Answer:

360 msec

Explanation:

Data provided in the question:

Distance between the two hosts = 15,000 kilometer

= 1.5 × 10⁷ m    [ ∵ 1 km = 1000 m ]

Transmission rate, R = 5 Mbps = 5 × 10⁶ bits per second

Propagation speed over the link = 2.5 × 10⁸ meters/sec

Size of file to be sent = 1,500,000 bit

Now,

Propagation delay (dprop)

= Distance ÷ Speed

= ( 1.5 × 10⁷ ) ÷ (2.5 × 10⁸)

= 0.06 sec

= 60 msec           [ ∵ 1 sec = 1000 millisecond ]

Transmission delay (dtrans)

= Size of file ÷ Rate of transmission

= 1500000 ÷ ( 5 × 10⁶ )

= 0.3 sec

= 300 msec

Therefore,

Time required for transmitting the file

= Propagation delay + Transmission delay

= 60 msec + 300 msec

= 360 msec

Final answer:

The total time to send a 1,500,000-bit file from host A to host B over a distance of 15,000 kilometers at a rate of 5 Mbps is 0.36 seconds, which is the sum of the transmission time (0.3 seconds) and the propagation delay (0.06 seconds).

Explanation:

To calculate the time taken to send a 1,500,000-bit file from host A to host B separated by 15,000 kilometers at a rate of 5 Mbps, you need to consider both the transmission time and the propagation delay. The transmission time is the time required to push all the file's bits onto the wire and is given by the file size divided by the transmission rate. The second part is the propagation delay, which is the time it takes for the first bit to travel from the source to the destination.

The transmission time can be calculated as: Transmission Time = File size / Rate = 1,500,000 bits / (5 x 10⁶ bits/sec) = 0.3 seconds.

The propagation delay is the distance divided by the speed of light in the medium, which is: Propagation Delay = Distance / Speed of light = 15,000 km / (2.5 x 10⁸ m/s) = 0.06 seconds. Since the distance needs to be in meters, we convert it by multiplying by 1,000: Propagation Delay = 15,000,000 m / (2.5 x 10⁸ m/s) = 0.06 seconds.

The total time to send the file is the sum of transmission time and propagation delay: Total Time = Transmission Time + Propagation Delay = 0.3 s + 0.06 s = 0.36 seconds.

Answer:

salary = 1250

numofDependents = 2

stateTax = (6.5/100)*salary

federalTax = (28/100)*salary

dependentDeduction = ((2.5/100)*salary)*(numofDependents)

totalWithHolding = stateTax+federalTax+dependentDeduction

takeHomePay = salary - totalWithHolding

print('State Tax: {}'.format(stateTax))

print('Federal Tax: {}'.format(federalTax))

print('Dependents: {}'.format(dependentDeduction))

print('Salary: {}'.format(salary))

print('Take Home: {}'.format(takeHomePay))

MODIFIED TO ACCEPT FOR SALARY AND NUMBER OF DEPENDENTS

salary = float(input("Please enter your salary: "))

numofDependents = int(input("How many dependents do you have "))

stateTax = (6.5/100)*salary

federalTax = (28/100)*salary

dependentDeduction = ((2.5/100)*salary)*(numofDependents)

totalWithHolding = stateTax+federalTax+dependentDeduction

takeHomePay = salary - totalWithHolding

print('State Tax: {}'.format(stateTax))

print('Federal Tax: {}'.format(federalTax))

print('Dependents: {}'.format(dependentDeduction))

print('Salary: {}'.format(salary))

print('Take Home: {}'.format(takeHomePay))

Explanation:

See the attached screen shot for the input and program output

The input Statement in python is used to receive and store the values for salary and number of dependents

Final answer:

To calculate the taxes and take-home pay in Python, modify the code to accept user input for salary and dependents, then calculate state and federal tax, dependent deductions, total withholding, and take-home pay. The input is processed to dynamically produce the specified outputs, including taxes and deductions.

Explanation:

To calculate the taxes and take-home pay in Python, we would start by modifying the initial code to accept user input for the salary and the number of dependents. This can be done using the input() function in Python. After obtaining these inputs, we apply the specified rates to calculate state withholding tax, federal withholding tax, and dependent deductions. Finally, we calculate the total withholding and take-home pay.

Here is an example of how the code could look:

salary = float(input('Enter your salary: '))
numDependents = int(input('Enter the number of dependents: '))
stateTax = salary * 0.065
federalTax = salary * 0.28
dependentDeduction = salary * 0.025 * numDependents
totalWithholding = stateTax + federalTax + dependentDeduction
takeHomePay = salary - totalWithholding
print(f'State Tax: $',stateTax)
print(f'Federal Tax: $',federalTax)
print(f'Dependents: $',dependentDeduction)
print(f'Salary: $',salary)
print(f'Take-Home Pay: $',takeHomePay)

This code snippet will dynamically calculate the taxes and take-home salary based on the user's input, making the program more useful and interactive.

Relational data model:

The use of data tables to organize sets of entities into relationships requires a relational data model. this model work on the assumption, which is a primary key or code, that is included in each table configuration. The symbol for "relational" data links and information is used by other tables.

Model Design:

This model is used for database management, it consists of structure and language consistency. It is design in 1969.

Importance of data model:  

This provides a common standard for processing the potentially sound data in machines, that was usable on almost any one device.  

Big Data:

It moves to locate new and innovative ways to handle large volumes of authentication tokens and to gather business insights when offering high efficiency and usability at an affordable cost at the same time.

Final answer:

The question involves displaying how a string and numerical data will be stored in hexadecimal format in memory on a machine with both big-endian and little-endian architectures. The storage pattern involves converting ASCII strings and numbers into hexadecimal format and then storing them sequentially in memory according to the endianess. Exact hexadecimal values would require ASCII and IEEE 754 format conversions.

Explanation:

The given question involves storing textual and numerical data on a byte-addressable machine that uses 32-bit integers and single-precision floating-point format, according to the IEEE 754 standard. The data to be stored includes a string 'Inventory', a decimal integer value (569)10, a string 'Price', and a decimal floating-point number (49.75)10. We are asked to show how this information would be stored in both big-endian and little-endian representation. Firstly, we need to translate the ASCII strings and numerical values into hexadecimal, suitable for storage in memory:

The string 'Inventory' is broken into 32-bit words and converted to hexadecimal.

The integer value 569 is represented in hexadecimal as 0x00000239.

The string 'Price' is similarly broken into 32-bit words and converted to hexadecimal.

The floating-point number 49.75 is converted into IEEE 754 single-precision format and represented in hexadecimal.

For big-endian representation, the most significant byte (MSB) is stored at the lowest memory address:

Each character of 'Inventory' and 'Price' is represented by its ASCII hexadecimal value and stored in sequential memory addresses, starting with the MSB.

The integer and floating-point numbers are stored with their MSB first in the 32-bit word boundary.

For little-endian representation, the least significant byte (LSB) is stored at the lowest memory address:

Each character of 'Inventory' and 'Price' is represented in reverse order compared to big-endian.

The integer and floating-point numbers are also reversed, with the LSB first.

The exact hexadecimal values in memory would depend on the binary representations of the strings and the specifics of the IEEE 754 conversion process for the number 49.75.

Answer:

The correct option is B: Old brick-and-mortar rules, regulations, and habits

Explanation:

Globalization has been made possible because of the internet. However, the promise of what is considered "borderless commerce" is limited due to the old brick and mortar rules, regulations, and habits. Brick and mortar is considered the traditional businesses offering products and services to customer in a rented or owned store and requires face-to-face business. Hence globalization via the internet is limited because companies have to sort out their building and stores, follow every law and regulation to opening offices and other habits practiced by these brick-and-mortar businesses.

Answer:

85 %

Explanation:

Historically, data warehouses had been formed using structured repetitive data that was filtered before entering the data warehouse. However, in recent years, the data warehouse has evolved due to contextual information that can now be attached to unstructured data and that can also be stored.

Those first structured relational data could not be mixed and matched for analytical subjects with unstructured textual data. But with the advent of contextualization, these types of analyzes can now be done naturally and easily.

Classic analytical processing of transaction-based data is performed in the data warehouse as it has always been done. Nothing has changed there. But now you can become analytical about contextualized data, and that form of analysis is new. Most organizations, until now, did not have to base their decision making on unstructured textual data. And now there is a new way of analysis possible in a Data Warehouse: the possibility of mixing analysis. The combined analysis is performed by a combination of structured transactional data and unstructured contextual data.

According to a research by Merrill Lynch indicates that 85 % of all coporate date is stored in some sort of unstructured form like data warehouse.

Final answer:

To solve the student's problem, input the current and last month's house prices, calculate the price change, compute the estimated mortgage, and correctly format the output presenting the figures.

Explanation:

To create a program that takes the current price and last month's price of a house as inputs, and outputs a summary of the price change and estimated monthly mortgage, follow these instructions:

Here's how the output should look like:

This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.000000.

```python

current_price, last_month_price = map(int, input().split())

print(f'This house is ${current_price}. The change is ${last_month_price - current_price} since last month. The estimated monthly mortgage is ${(current_price * 0.051) / 12:.6f}.')

```

The program takes two integer inputs, representing the current house price and last month's price. It then uses a formatted string to output a summary, including the current price, the change since last month (calculated by subtracting the current price from last month's price), and the estimated monthly mortgage computed using the given formula. The use of f-strings in Python allows for concise and readable code, embedding expressions directly within the string.

The map function is employed to convert the input values into integers. The program calculates the change in price by subtracting the current price from last month's price. To ensure precise spacing and formatting, the f-string includes the required text and variable values in a structured manner. The estimated monthly mortgage is calculated using the provided formula and formatted as a floating-point value with six decimal places.

The code adheres to the assignment's emphasis on precision in spacing, punctuation, and newlines. By using f-strings and the specified formula, the program produces the required output with clarity and accuracy.

There are three packages: Package A offers 10 hours for $9.95 with additional hours at $2 each, Package B provides 20 hours for $14.95 with additional hours at $1 each, and Package C offers unlimited access for $19.95. The program will also calculate potential savings for customers of Package A if they switch to Package B or C, and for Package B customers if they switch to Package C, provided switching would result in savings.

The largest numeric value that can be represented in 3 bytes is 224

Explanation:

Final answer:

The largest value with three bytes using ASCII is 127127127, but for practical numerical storage in binary notation, the largest value with three bytes is 16777215, represented as 11111111 11111111 11111111 in binary.

Explanation:

The largest numeric value that could be represented with three bytes using one ASCII pattern per byte depends on the ASCII printable characters range. ASCII characters are represented within the range of 0 to 127, therefore in three bytes, the largest decimal values you could represent would be 127127127. However, this is not typically how numeric values are stored.

When using binary notation, each byte consists of 8 bits, and the maximum value for each bit is 1. Therefore, the largest value in a single byte is 11111111, which is 255 in decimal. Hence, in three bytes, the largest decimal number that can be stored is 16777215 (which is 11111111 11111111 11111111 in binary).

Final answer:

The task requires a Python code using a for loop to count down from a specified starting number, printing 'Ready!', each number on a new line, and 'Run!' at the end.

Explanation:

To write code that counts down from a given number and prints 'Ready!', followed by each number, and ending with 'Run!', we can use a for loop. Here is a sample Python code snippet that accomplishes this:

firstNumber = 3
print('Ready!')
for num in range(firstNumber, 0, -1):
   print(num)
   print('\n')
print('Run!')

This code starts by printing 'Ready!', then it enters a for loop that counts down from firstNumber to 1, printing each number followed by a newline. Finally, it prints 'Run!' after exiting the loop. Remember to replace firstNumber with the actual starting number you wish to count down from.

Final answer:

The question involves creating an algorithm to generate permutations of a given string without altering the positions of uppercase alphabets, a problem suitable for Computers and Technology at the college level.

Explanation:

The task requires generating all permutations of a given string while maintaining the original positions of the uppercase alphabets. This is typically a problem that can be approached algorithmically, falling under the category of Computers and Technology. To solve it, you would need to find permutations of the lowercase letters only and then insert them back into the string at the positions not occupied by uppercase letters.

One way to achieve this is to extract all lowercase letters and use a permutation algorithm, such as Heap's algorithm, to generate all permutations while the uppercase letters act as anchors, holding their respective positions fixed. As each permutation of the lowercase letters is generated, it's interlaced with the uppercase ones to construct a full-string permutation that meets the condition. This process is repeated until all permutations of the lowercase characters are exhausted.

Answer:

There are four options for this question: A and D are correct.

A. By adding a mobile layout and assigning it to a profile.

B. By adding quick actions in the publisher section

C. By adding actions in the Salesforce1 action bar section.

D. By adding Visualforce page to the mobile cards section.

Explanation:

We can add a different view for the users instead of the standard web, we can use a mobil design and assign a different profile, addition, we can implement the visualforce page to create a new view, with this option we make a better and interesting user interface with interaction with different views.
