Answer:
Partial and disjoint
Explanation:
Since there is overlapping in relationship of HAIR_STYLIST and MANAGER it can't be tree structure.
A MANAGER can or can't be HAIR_STYLIST. In order for the relationship to be multiple inhertiance am entity in sub-class has to be union of all subclasses
In single inheritance, a sub-class has to be a union of a single super class.
In partial and disjoint, some entity in super class may or may not be related to a sub-class.
Write a function called print_kth_top_movie_year. It should take a single argument, the rank of the year (like 2, 3, or 5 in the above examples). It shouldn't have a return statement.
Final answer:
Creating a function to print the kth top movie year involves programming skills, understanding of data structures, and error handling. In the example provided, Python is used to access a list of movie years sorted by rank and print the year at the provided rank, illustrating both functional logic and basic error management.
Explanation:
Creating a function in a programming language to print the kth top movie year involves selecting a programming language (like Python), then utilizing data about movie years and their ranks. The function, print_kth_top_movie_year, would likely access a pre-sorted or dynamically sorted list or array of movie years based on some criteria, such as box office success, critical acclaim, or other metrics. Given the specificity of the task, it assumes access to structured data about movies.
For example, in Python, one might start with creating a list of movie years and their rankings. Then, the function would use the rank (an integer) as an index to find and print the respective year from the list. It's important to handle cases where the rank provided is out of range, ensuring the function gracefully handles such errors without crashing.
An illustration of this in code (assuming Python and a predefined list of movie years named movie_years_ranked):
def print_kth_top_movie_year(k):
try:
print(movie_years_ranked[k-1]) # Adjust for zero-based indexing
except IndexError:
print("Rank out of range.")
Write an if-else statement to describe an integer. Print "Positive even number" if isEven and is Positive are both true. Print "Positive number" if isEven is false and is Positive is true. Print "Not a positive number" otherwise. End with newline.
Answer:
C code explained below
Explanation:
#include <stdio.h>
#include <stdbool.h>
int main(void) {
int userNum;
bool isPositive;
bool isEven;
scanf("%d", &userNum);
isPositive = (userNum > 0);
isEven = ((userNum % 2) == 0);
if(isPositive && isEven){
printf("Positive even number");
}
else if(isPositive && !isEven){
printf("Positive number");
}
else{
printf("Not a positive number");
}
printf("\n");
return 0;
}
Write a Scheme function that takes two atoms and a list as parameters and returns a list identical to the parameter list except all occurrences of the first given atom in the list are replaced with the second given atom, no matter how deeply the first atom is nested.
Answer:
(define (delete-atom list atom )
(cond ((null? list) '()) ;;if list is empty returns empty
((equal? (car list) atom) (delete-atom (cdr list) atom)) ;;checking fiest element of element of list with item
(else (cons (car list) (delete-atom (cdr list) atom))))) ;;recursively check for rest of the elements
Explanation:
atom is first compared with first element of list, if both are equal it recursively calls that function with deleting first element. if both are not equal it cons the first element and recursively calls rest of the elements.
Obeserve that if list is nested list for ex '((1 2) 2 3) and if we want to delete 2 it returns ((1 2) 3) becuase it deletes top level of 2 only. when (car list) i., (2 3) compared with 2, both are not equal and it cons the entire sublist ((2 3) and recursively calls delete-atom function. so it doesn't deletes the element inside and deletes top level only.
Consider a simple list '( 1 2 3). Here deleting 1 is just a simple deletion and returns (2 3)
consider deleting 1 from top level of a nested list '(1 2 3 (1 3) 1 3 4) returns (2 3 (1 3) 3

The given example is of looping because each activity is leading to another activity on the completion of some conditions. The answer a is not valid as it is not just an example of conditional statements rather it is a loop which will keep moving until unless reached a situation to end it.The option c, d an e are not right options for the given example.Which sort has the best big-oh in the best case? Which sort has the best big-oh in the worst case? Which sort does the most swapping in the worst case. Which sorts swap? Which sorts shift? What is the best big-oh off all the sorts?
Answer:
The answer to these questions can be defined as below:
Explanation:
Question 1:
In the best case big-oh the bubble and selection sort is used, where bubble style simply swaps the items, whereas the sort of sorting takes place by choosing the element.
Question 2:
In the worst case, the merge and selection is used, where Merge-sort splits the list into two sub-lists equally and incessantly names itself in the sublists to still be sorted, whereas Heap-sort is an anti-recursive type.
Question 3:
In the worst case of swapping the bubble sort algorithm is used.
Question 4:
In sorts of swap selection, bubble, and quick sort is used.
Question 5:
Insertion sorts provide the shift sorts.
Question 6:
The best big-oh is o(n), in the worst case, best case complexity of different sorts are different.
Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 38 then the output is: 83 Your program must define and call a function. SwapValues returns the two values in swapped order. void SwapValues (int* userVali, int* userVal2) LAB ACTIVITY 6.22.1: LAB: Swapping variables 22.1. LAB 0/10 ] main.c Load default template... #include /* Define your function here */ int main(void) { Ovo AWN /* Type your code here. Your code must call the function. */ return 0; 10 }
Answer:
Following are the program in the C++ Programming Language.
#include <iostream>
using namespace std;
//define function for swapping
void SwapValues(int* userVal1,int* userVal2){
//set integer variable to store the value
int z = *userVal1;
//interchange their value
*userVal1 = *userVal2;
//interchange their value
*userVal2 = z;
}
//define main method
int main()
{
//declare variables
int x,y;
//get input from the user
cin>>x>>y;
//Call the method to swap the values
SwapValues(&x,&y);
//print their values
cout<<x<<" "<<y;
return 0;
}
Output:
3 8
8 3
Explanation:
Following are the description of the program.
Firstly, we define required header file and function 'SwapValues()', pass two pointer type integer variables in argument that is 'userVal1' and 'userVal2'.Set integer data type variable 'z' and initialize the value of 'userVal1' in it, then initialize the value of 'userVal2' in 'userVal1' and then initialize the value of 'z' in 'userVal2'.Finally, define the main method in which we set two integer type variables and get input from the user in it then, call and pass those variables and print it.To swap two integers in C, you define a function using pointers. The program reads two integers, swaps them using this function, and then prints the swapped values. Implementing SwapValues ensures correct swapping.
To swap two integers in C, you need to use a function that takes pointers as arguments. A particularly clever application of pointer manipulation allows us to swap the values of two variables.
Firstly, let's define the function SwapValues:
void SwapValues(int* userVal1, int* userVal2) { int temp = *userVal1; *userVal1 = *userVal2; *userVal2 = temp; }
Inside main(), we will call this function:
#include <stdio.h>
void SwapValues(int* userVal1, int* userVal2);
int main(void) { int num1, num2;
scanf("%d %d", &num1, &num2);
SwapValues(&num1, &num2);
printf("%d %d\n", num1, num2);
return 0; }
This code reads two integers, swaps them using the SwapValues function, and prints the result.
A variation of client-server computing is ____, in which software that allows for applications are installed on servers and then accessed and executed through desktop clients, instead of installing applications on each individual client computer.
Answer:
Terminal services
Explanation:
Terminal services are multiuser, lean client environment from Microsoft which was built for Windows servers. It was first launched on the Windows NT 4.0 in 1996, as of the 2009 the launch of Windows Server 2008 R2, it became part of Remote Desktop Services (RDS), and exclusively, the "shared sessions" method in RDS.
Just like in the old times of mainframes, Terminal Services supports numerous users connected to a central computer. The user's device can be a compact PC, bare-bones PC or a dedicated terminal, and all of them are to function as input/output (I/O) terminals and use the same OS and applications running in the server. Terminal Services utilizes the Microsoft's Remote Desktop Protocol (RDP) to govern mouse, keyboard and screen transfer.
You are required to come up with a single header file (IntList.h) that declares and implements the IntNode class (just copy it exactly as it is below) as well as declares the IntList Class interface only. You are also required to come up with a separate implementation file (IntList.cpp) that implements the member functions of the IntList class. While developing your IntList class you must write your own test harness (within a file named main.cpp).
Never implement more than 1 or 2 member functions without fulling testing them with your own test harness. IntNode struct I am providing the IntNode class you are required to use. Place this class definition within the IntList.h file exactly as is. Make sure you place it above the definition of your IntList class. Notice that you will not code an implementation file for the IntNode class. The IntNode constructor has been defined inline (within the class declaration). Do not write any other functions for the IntNode class. Use as is.

IntList(): Initializes an empty list.
~IntList(): Deallocates all remaining dynamically allocated memory (all remaining IntNodes). void display() const: Displays to a single line all of the int values stored in the list, each separated by a space. This function does NOT output a newline or space at the end.
void push_front(int value): Inserts a data value (within a new node) at the front end of the list.
void pop_front(): Removes the value (actually removes the node that contains the value) at the front end of the list. Does nothing if the list is already empty.
bool empty() const: Returns true if the list does not store any data values (does not have any nodes), otherwise returns false. main.cpp test harness for lab
Use this main.cpp file for testing your IntList:
. #include using namespace std; #include "IntList.h" int main() {
//tests constructor, destructor, push_front, pop_front, display { cout << "\nlist1 constructor called"; IntList list1;cout << "\npushfront 10"; list1.push_front(10); cout << "\npushfront 20"; list1.push_front(20); cout << "\npushfront 30"; list1.push_front(30); cout << "\nlist1: "; list1.display(); cout << "\npop"; list1.pop_front(); cout << "\nlist1: "; list1.display(); cout << "\npop"; list1.pop_front(); cout << "\nlist1: "; list1.display(); cout << "\npop"; list1.pop_front(); cout << "\nlist1: "; list1.display(); cout << endl; } cout << "list1 destructor called" << endl; return 0;}

A nearest neighbor approach is best used: (a) With large-sized data sets. (b) When irrelevant attributes have been removed from the data. (c) When a generalized model of the data is desirable. (d) When an explanation of what has been found is of primary importance. Select only one choice and give additional explanations
Answer:
(b) When irrelevant attributes have been removed from the data.
Explanation:
A nearest neighbor approach -
It refers to the method of searching where the nearest point from the given set can be determined with respect to some specific point , is referred to as the nearest neighbor approach .
The method is used for the purpose of finding soe data in order to replace , edit , remove or add some data .
Hence , from the given question ,
The correct answer about nearest neighbor approach is b.
A Nearest Neighbor approach is best used when irrelevant attributes have been removed from the data. This algorithm works best when the dataset is clean and free of irrelevant, misleading, or noisy data. It is less effective with large data sets, and doesn't provide a generalized model or easy explanation of results.
Explanation:A Nearest Neighbor approach in machine learning is typically best used when irrelevant attributes have been removed from the data. This type of algorithm generally works well when the dataset is clean and free of irrelevant, misleading, or noisy data that could interfere with finding the nearest neighbors. Notably, it does not work as effectively with large data sets due to computational demands. Furthermore, it does not provide a generalized model of the data or an easy explanation of the results, which eliminates options (a), (c), and (d).
To illustrate, consider a dataset used for predicting house prices. Irrelevant attributes including the house color, name of the owner, etc., have to be removed for the Nearest Neighbor algorithm to be effective as they do not have a direct impact on the house price. The algorithm then identifies the 'neighbor' house prices that are most similar to the house price we're trying to predict.

Suppose that the UDP receiver computes the Internet checksum for the received UDP segment and finds that it matches the value carried in the checksum field.
Can the receiver be absolutely certain that no bit errors have occurred?
Answer:
No, the receiver cannot be absolutely certain that no bit errors have occurred. This is because of the manner in which the checksum for the packet is calculated. If the corresponding bits (that would be added together) of two 16-bit words in the packet were 0 and 1 then even if these get flipped to 1 and 0 respectively, the sum still remains the same. Hence, the 1s complement the receiver calculates will also be the same. This means the checksum will verify even if there was transmission error
Explanation:
No, the receiver cannot be confident that there haven't been any bit mistakes.
What is UDP?UDP stands for user data protocol. UDP is defined as a messaging protocol that makes it easier for computers to communicate with one another via a network. A communications protocol called User Datagram Protocol (UDP) is largely used to provide low-latency, loss-tolerant connections between internet-based applications. UDP allows data to be transferred before the receiving party provides an agreement, which speeds up transfers.
A checksum field on UDP allows for the detection of IP header errors; if a checksum error is found, the IP header checksum is recalculated before the IP packet is delivered. Therefore, it cannot ensure that your package will reach the receiver. However, UDP does guarantee that if it is delivered, it will be error-free.
Thus, no, the receiver cannot be confident that there haven't been any bit mistakes.

Question 3. Using simulation with 10,000 trials, assign chance_of_all_different to an estimate of the chance that if you pick three words from Pride and Prejudice uniformly at random (with replacement), they all have different lengths. Hint: Remember that !
Final answer:
The chance of picking three words with different lengths from Pride and Prejudice can be estimated using a simulation of 10,000 independent trials, checking for unique word lengths in each trial.
Explanation:
To estimate the chance that if you pick three words from Pride and Prejudice uniformly at random (with replacement), they all have different lengths, you need to perform a simulation with 10,000 trials. This simulation involves generating lengths for three different words and checking if all lengths are unique, then repeating this trial 10,000 times to estimate the probability of this event.
Each word length can be thought of as a random variable, and since words are picked with replacement, the trials are independent. Use the principle of statistical independence as well as discrete distribution and the concept of distinguishability of random variables to structure the simulation. For example, you could use a list of words from the book and their lengths. In each trial, three word lengths would be randomly selected with replacement, and you would check if all three are different. The series of trials would give you a proportion of trials where all the word lengths are different. However, this problem is not a binomial distribution, as each trial can have more than two outcomes.
In this Python code, a simulation is performed to determine the number of times, out of 10,000 trials, that two words chosen randomly with replacement from the text "Pride and Prejudice" have different lengths.
Import random module: This module is used for random number generation.
Define the list of words from "Pride and Prejudice": Replace the ellipsis (...) with the actual list of words from the text.
Set the number of trials and initialize num_different to 0:
trials is the number of times you want to repeat the experiment.
num_different will keep track of the number of times two words have different lengths.
Run the simulation using a for loop:
The loop runs trials times.
Inside the loop, two words are randomly chosen from the list using random.choice().
Check if the lengths of the two words are different:
If the lengths are different, increment num_different.
Print the result:
After the loop, print the final count of num_different.
import random
# Assume you have a list of words from "Pride and Prejudice"
pride_and_prejudice_words = ["word1", "word2", "word3", ...] # Replace ellipsis with the actual words
trials = 10000
num_different = 0
# Run the simulation
for _ in range(trials):
# Randomly pick two words with replacement
word1 = random.choice(pride_and_prejudice_words)
word2 = random.choice(pride_and_prejudice_words)
# Check if the lengths of the two words are different
if len(word1) != len(word2):
num_different += 1
# Print the result
print("Number of times two words have different lengths:", num_different)
This code will give you an estimate of the number of times two words with different lengths are chosen randomly from "Pride and Prejudice" in 10,000 trials.
Complete question:
Using a simulation with 10,000 trials, assign num_different to the number of times, in 10,000 trials, that two words picked uniformly at random (with replacement) from Pride and Prejudice have different lengths. Hint 1: What function did we use in section 1 to sample at random with replacement from an array? Hint 2: Remember that != checks for non-equality between two items. trials = 10000 num_different = ... for ... in ...: num_different =... num_different
There is a way to use Linux commands to display all programs with the setuid bit on. I run this periodically to look for programs that are setuid and owned by root, and I jot down the number of them. If this number gets larger it may indicate a security breech. Why
Answer:
The SUID bit is a type of permission files that is previously granted to a file. In Linux when you run a program, these special permissions are inherited to the user who is working. The SUID grants permissions to a user temporarily.
Explanation:
If the time lengthens, it is possibly due to a security breach. A change of the password is recommended, through the passwd command. Through this command, some files cannot be opened or seen by the user, only by the user who has root permissions. By configuring the passwd through the SUID we can grant root user permissions to any type of user, so that in such case update, use the shadow and files.
Monitoring setuid root programs helps spot security risks. These programs have high privileges and can be exploited if compromised. A sudden increase might indicate a new risky program or a malicious attack. But it's not the only sign, so stay familiar with your system's programs.
You're right on track! Monitoring the number of setuid programs owned by root is a good security practice. Here's why:
Setuid programs have elevated privileges: The `setuid` bit allows a program to run with the permissions of the file's owner, even if the user running it doesn't have those permissions themselves. This is useful for some programs that need to access resources or perform actions that normal users can't.
Root ownership implies high privilege: Programs owned by `root` have the highest level of permissions on the system.
Security vulnerabilities in setuid root programs are critical: If a program with `setuid` and root ownership has a security vulnerability, an attacker can exploit it to gain complete control of the system. This is because the program is already running with the most powerful privileges.
By monitoring the number of `setuid root` programs, you can potentially detect:
Accidental addition:*A new program might have been incorrectly given `setuid` privileges, creating an unnecessary risk.
Malicious activity: An attacker might try to add a malicious program with `setuid root` permissions to gain access.
However, it's important to note that a sudden increase isn't the only indicator of a security breach. Here are some additional points to consider:
Some legitimate programs require setuid root: There are valid reasons for some system programs to be `setuid root`. You'll need to be familiar with the expected setuid programs on your system.
Look for changes in specific programs: A program that wasn't previously `setuid root` becoming so is more suspicious than a known program remaining setuid.
In conjunction with monitoring the number of `setuid root` programs, consider these security practices:
Keep your system updated: This includes patching the kernel and all installed software.
Minimize the number of setuid root programs: If a program doesn't strictly need `setuid` privileges, remove them.
Use tools for a more comprehensive security check: There are system security scanners that can help identify vulnerabilities in setuid programs.

The firm plans to hold about dozens of different regional competitions at various dates that will take place at different branches around the country. For each competition, you need to store a name, date, and the name of the branch where it is going to take place. For each college that has agreed to participate in the competition, you need to store the college name, a contact phone number, and a contact address. Each college can participate in only one competition, and the database should know which competition each college is participating in. On the other hand, each college is allowed to send more than one team to its competition. Each team gives itself a name and a color, and consists of several students of the same college; for each student, you want to store a first name, last name, date of birth, major, and expected graduation date. Question: How many tables do you need
Answer:
We will ned (4) four tables.
Explanation:
For the given scenario we will have to build a relational database. The database will have four tables i.e. Competation, Collage, Team and student.
For each table the database fields are mention below. Note that foreign keys are mentioned in itallic.
Competition:
Competition_ID, Competition_Name, Competition_Data, Competition_Name _of_Branch, College_ID
Collage:
Collage_ID, Collage_Name, Collage_Contact, Collage_address
Team:
Name, Color, Team_ID, College_ID, Competition_ID
College:
Student_ID, First_Name, Last_Name, Date_of_Birth, Major, Expected_Gradiuation_Date, Collage_ID, Team_ID, Competation_ID
To organize the required data for your firm's case competitions, you would need to create four tables: Competitions, Colleges, Teams, and Students. These tables would store competition details, college contact information, team names and colors, and student demographics, respectively.
Explanation:Databases organize information into tables that are composed of rows and columns where each row is a record for an entity and each column is an attribute of the entity. For your case competition database, you will need different tables to store related data without redundancy. The goal here is consistency, efficiency, and comprehensibility. Let's break down the tables you would require:
A Competitions table to store each competition's name, date, and branch location.A Colleges table to store participating college's name, contact phone number, and address, with a reference to the competition they are participating in.A Teams table to record each team's name, color, and associated college.A Students table to keep track of all student participants' first name, last name, date of birth, major, and expected graduation date, with a reference to their team.By designing your database with these four tables, you ensure data is grouped logically and related information is linked appropriately to eliminate the need for repeated data entry and promote efficient data management.
When using an IDE, what must you do to use a class that's stored in a library? Select one: a. Nothing. Classes in libraries are automatically available. b. Code an import statement for the class. c. Add the library to your project. d. Both b and c.
Answer:
Both B and C
Explanation:
In order to use methods from another class (library) in your code, the class library will have to be added or imported into your code.
This is implemented in different ways across different programming languages, for example;
Java uses the keyword import followed by the class library name
C++ uses the key word #include
C# Uses the keyword using
Answer:
Both b and c.
Explanation:
In my opinion, I think the IDE determines how to use the class. While you import some, some have to be added to your project
British mathematician Alan M. Turing wrote a number of papers on theoretical computer science. In one paper, written in 1936 before any programmable computer had ever been built, he described the logical structure any such machine would have to possess. His description of an idealized computer specified in mathematical terms the relations between the input, output, actions, and states of what is called a Turing machine.
What can the reader infer from the passage?
A. Turing invented the first computer.
B. Turing physically developed the structure of a programmable computer.
C. Turing analyzed the first computer.
D. Turing conceived the structure of a programmable computer.
Answer: D. Turing conceived the structure of a programmable computer.
Explanation: The passage describes how Alan M. Turing described the theoretical aspect of a programmable computer. There is no reference to a physical machine or Turing working on an actual (physical) computer.
The Turing machine, although it does sound like a physical computer was an abstract idea, conceived in mathematical form of what a programmable machine would be like. Alan Turing is considered one of the founding fathers of theoretical computer science.
The correct answer is D. Turing conceived the structure of a programmable computer.The passage indicates that Alan Turing conceived the theoretical structure of a programmable computer in 1936. He did not physically build or analyze an actual computer.
The passage describes how Alan Turing, a British mathematician, conceived the structure of a programmable computer in a 1936 paper. He did not invent or physically build the first computer but outlined its logical framework in mathematical terms, which later became known as the Turing machine. Turing's work laid the foundation for modern computers and is why he is regarded as the father of theoretical computer science and artificial intelligence.Turing conceived the structure of a programmable computer: The passage explains Turing’s conceptual and theoretical contributions rather than any physical development or analysis of an existing computer.Thus The correct answer is D. Turing conceived the structure of a programmable computer.
Write a function stats that takes an array and the number of elements in the array. Then, it computes and prints the minimum value, maximum value, and the average value of all the values in the array. The output should be formatted with a two-digit precision. The function name: stats The function parameters (in this order): an array, double The number of elements in the array, int The function should not return anything.
Answer:
#include<iostream>
using namespace std;
void stats(double [],int);
int main()
{
int totalElements,i;
cout<<"Enter total elements:"<<endl;
cin>>totalElements;
double array[totalElements];
cout<<"Enter the elements in array:"<<endl;
for(i=0;i<totalElements;i++)
cin>>array[i];
stats(array,totalElements);
}
void stats(double array[],int totalElements)
{
int i;
double minimum,maximum;
double Sum=0.0,average=0.0;
minimum=array[0],maximum=array[0];
for(i=0;i<totalElements;i++)
{
if(array[i]>maximum)
maximum=array[i];
if(array[i]<minimum)
minimum=array[i];
Sum+=array[i];
}
average=Sum/totalElements;
cout<<"Test: ";
for(i=0;i<totalElements;i++)
cout << fixed << setprecision(2) <<array[i]<<" ";
cout<<endl;
cout <<"minimum:"<< fixed << setprecision(2) <<minimum<<endl;
cout <<"maximum:"<< fixed << setprecision(2) <<maximum<<endl;
cout <<"average:"<< fixed << setprecision(2) <<average<<endl;
}
Explanation:
Loop through the total elements to get the input from user and call the stats function.In the stats function check whether a number is maximum, minimum or average.Calculate the average by finding the sum of all the numbers in array and dividing it by total numbers.Finally display the results.
Final answer:
The 'stats' function calculates and prints the minimum, maximum, and average values from a given array with two-digit precision.
Explanation:
The function named stats is designed to compute statistical values such as the minimum value, maximum value, and the average value of elements in an array. The function takes two parameters: an array of type double and the number of elements in the array of type int. It then proceeds to calculate the required statistics and prints them with a precision of two decimal places. This function does not return any value as its primary purpose is to print out the calculated statistics.
Write a short reflection piece (it may consist of three bulleted items, with one explanatory sentence) on three things you learned about computer architecture and/or operating systems.
Answers
OS(The Operating System) sends interrupts to the processor to stop whatever is being processing at that moment and computer architecture send data bus. This bus sends data between the processor,the memory and the input/output unit.The operating system is a low-level software that supports a computer’s basic functions, such as scheduling tasks and controlling peripherals while the computer architecture has the address bus bar. This bus carries signals related to addresses between the processor and the memory. The interface between a computer’s hardware and its software is its Architecture while An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.Explanation:
In short explanation,the Computer Architecture specifically deals with whatever that's going on in the hardware part of the computer system while the Operating System is the computer program which has been program to execute at some instances depending on the programming instructions embedded in it. An example is the MS Office.
Nunya is a computer software company that employs highly intelligent, but somewhat unusual people. Every Friday, free lollipops, toys, or other treats are given out to encourage employees to remember how creative they were when they were children. All the new members of the organization are told about the founders who were three young people who "got lucky" and sold a video game that they invented. The employees are allowed to dress informally and can set their own working hours. Informing employees about the founders is an example of which technique for transmitting culture?
Answer:
Stories
Explanation:
Storytelling is regarded as being on the core of culture. Stories is a way of passing history down generations after generations, and how customs are being shared. It also denotes how people adopt a tradition and these traditions never change. The stories told by a group indicates the values of its culture. In the question, informing employees about founders is like telling them stories to pass customs, values, and tradition.
The easiest type of error to fix is Group of answer choices a runtime error because the program will halt when it gets to the error a user error because you can rewrite the code to account for this a syntax error because web browsers and IDEs provide helpful error messages a logic error because the program will run even with a logic error
Answer:
A Syntax error because web browsers and IDEs provide helpful error messages
Explanation:
A Syntax error occurs when an aspect of a code don't completely conform to the syntax of the programming language. They are mistakes in the source code, such as the misspelling of an instruction or failure to declare a label before using it in the program. This can be easily corrected by going back to the code to trace where the error and correcting it.
A person's birth date consists of the month, day, and year in which that person was born. The domain for a relation R is a set of people. There are at least two people in the group with the same birth date and at least two people with different birth dates. A person x is related to person y under the relation if they have the same birth date or if x's birth date is earlier than y's birth date. Which description correctly characterizes the relation?
The relation R in question is a partial order relation characterized as reflexive, antisymmetric, and transitive, based on the properties of birth dates among a set of people.
Explanation:The relation R described in the question operates under two conditions within the domain of people's birth dates: first, a person x is related to person y if they have the same birth date; second, x is related to y if his birth date is earlier than y's birth date. Given that there are at least two people with the same birth date and at least two people with different birth dates, the correct characterization for this relation is that it is reflexive, antisymmetric, and transitive. These characteristics define a partial order relation. Reflexive because every person is related to themselves (has the same birth date), antisymmetric because if person x is related to person y due to an earlier birth date, then y cannot be related to x in the same manner, and transitive because if person x is born earlier than person y, who in turn is born earlier than person z, then x is also born earlier than z.

Find the number of times a value appears in a list, and create a new list that contains the index positions where the value occurs in the list argument.
Answer:
Program :
list_1=[]#take the empty list.
size=int(input("Enter the size of the list: "))#take the size of the list from the user
for x in range(size): #for loop which insert the elemnt on the list.
list_1.append(int(input("Enter the "+str(x+1)+" element of the list: ")))#take the user input and insert the element.
element=int(input("Enter the element to be searched: "))#it take the elemnt to search.
loc=1#intialize the location value.
count=0
for x in list_1:#for loop to check the element.
if(x==element): #check the element.
print(loc,end=", ")#print the location of the element.
count=count+1
loc=loc+1
if(count==0):
print("The element is not present on the list")#print when elemnt are not present.
Output:
If the user input 5 for the size and 1,2,3,4,5 for the list and 5 for the element, then it will print 5.Explanation:
The above code is in python language which is used to take the size for the list, then take the value to add on the list.Then the element is entered from the user to search on the list.Then the element is searched on the list with the help of for loop.It prints the location when the element is matched.Design a program that gives simple math quizzes. The program should display two random numbers that are to be added, such as

Here is the pseudo-code to follow
//Declare the variables to hold intermediate and final values
Declare Integer rand1, rand2, sum ans
//Get the random numbers generated by the function
//random and assign those values in rand1 and rand2 respectively
Set rand1 = random(1, 999)
Set rand2 = random(1, 999)
//Dsiplay rand1 and rand2 in a formatted way treated for addition
Display
Answer:
import java.util.Scanner; import java.util.Random; public class Main { public static void main(String[] args) { int rand1, rand2, sum, ans; Random rand = new Random(); rand1 = rand.nextInt(1000); rand2 = rand.nextInt(1000); sum = rand1 + rand2; System.out.println(rand1 + " + " + rand2); Scanner input = new Scanner(System.in); System.out.print("Please enter your answer: "); ans = input.nextInt(); if(ans == sum){ System.out.println("Congratulations! You did it right!"); }else{ System.out.println("Wrong answer. The correct answer should be " + sum); } } }Explanation:
Firstly import Scanner and Random libraries which will be used to get input number and to generate random value (Line 1 -2).
Next declare all the necessary variables as given in pseudo-code (Line 7 - 8)
Then use nextInt method to randomly generate integer and assign them to rand1 and rand 2, respectively (Line 10 - 11). Next, sum up the two random values and assign it to variable ans (Line 12).
Display the two random numbers (Line 14) and create a Scanner object and prompt user input for answer (Line 16- 18).
Create an if-else condition to check if the input answer (ans) is equal to the real answer (sum) and display the appropriate message accordingly (Line 20 - 24).
write a function that takes a string as parameter, return true if it’s a valid variable name, false otherwise. You can use keyword module’s iskeyword() to determine if a string is keyword.
Answer:
The solution code is written in Python 3:
import keyword def checkValidVariable(string): if(not keyword.iskeyword(string)): return True else: return False print(checkValidVariable("ABC")) print(checkValidVariable("assert"))Explanation:
Firstly, we need to import keyword module so that we can use its iskeyword method to check if a string is registered as Python keyword (Line 1).
Next, we create a function checkValidVariable that takes one input string (Line 3). Within the function body, we use iskeyword method to check if the input string is keyword. Please note the "not" operator is used here. So, if iskeyword return True, the True value will be turned to False by the "not" operator or vice versa (Line 4-5).
We test the function by passing two input string (Line 9-10) and we shall get the sample output as follows:
True
False
Given dictionaries, d1 and d2, create a new dictionary with the following property: for each entry (a, b) in d1, if a is not a key of d2 (i.e., not a in d2) then add (a,b) to the new dictionary for each entry (a, b) in d2, if a is not a key of d1 (i.e., not a in d1) then add (a,b) to the new dictionary For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6:4, 5:12, 4:3, 3:9} Associate the new dictionary with the variable d3
Done in Python please!
Here's what I have:
d3 = {}
for i,v in d1.items():
if v in d2.keys():
d3[i] = d2[v]
Answer:
Python code explained below
Explanation:
# python code
import sys
import readline
from sys import stdin
import random
d1 = {2:3, 8:19, 6:4, 5:12}
d2 = {2:5, 4:3, 3:9}
d3 = {}
#for each entry (a, b) in d1
for i,v in d1.items():
# if a is not a key of d2
if i not in d2.keys():
# add (a,b) to the new dictionary
d3[i] = v
# for each entry (a, b) in d2
for i,v in d2.items():
# if a is not a key of d1
if i not in d1.keys():
#add (a,b) to the new dictionary
d3[i] = v
print "d3: ", d3
#output: d3: {8: 19, 3: 9, 4: 3, 5: 12, 6: 4}
Answer:
d1 = {2:3, 8:19, 6:4, 5:12}
d2 = {2:5, 4:3, 3:9}
d3 = {}
for key,value in d1.items():
if key not in d2.keys():
d3[key] = value
for key,value in d2.items():
if key not in d1.keys():
d3[key] = value
print(d3)
Explanation:
The code is written in python as instructed from the question.
d1 = {2:3, 8:19, 6:4, 5:12} This is the d1 dictionary entry with the key-value pair.
d2 = {2:5, 4:3, 3:9} This is the d2 entry with the key-value pair.
d3 = {} This is an empty dictionary to unpack values
for key,value in d1.items(): This code loops through dictionary d1 and get the key-value pair
if key not in d2.keys(): If any of key in d1 is not in d2 keys.
d3[key] = value Then add the key-value pair to the empty d3
for key,value in d2.items(): This code loops through dictionary d2 and get the key-value pair
if key not in d1.keys(): If any of key in d2 is not in d1 keys
d3[key] = value Then add the key-value pair to the empty d3
print(d3) Display the final key-value pairs of d3
Write a program to do the following: Load $t0 with 12 and call it x. Load 21 in $t1 and denote it as y. Finally, load 32 in $t2 and refer to it as z. Now, compute 3x2 +10y+5z. Output the result using syscall 1 (remember the result has to be in $a0). Write down the output number on your answer sheet.

addi $t1, $zero, 21 # y = 21
addi $t2, $zero, 32 # z = 32
addi $t3, $zero, 3
mul $t3, $t3, $t0
mul $t3, $t3, $t0 # $t3 = 3x^2
addi $t4, $zero, 10
mul $t4, $t4, $t1 # $t4 = 10y
addi $t5, $zero, 5
mul $t5, $t5, $t2 # $t5 = 5z
add $a0, $t3, $t4
add $a0, $a0, $t5 # $a0 = 3x^2 + 10y + 5z
addi $v0, $zero, 1
syscall
