Answer:
True is the correct answer for the above question.
Explanation:
The software design consists of several phases which are also called the life cycle. It is used to develop the software.But there are so many models, that consist of rules and guidelines to states how these phases can work. It states that in which steps of the designing phase, which part of the life cycle works.For example, in the waterfall model, all phases work on a single time and there is no option to follow this in reverse scenario and in the agile model only one module is developed and proved by the client.So the style of the phase can state the model, which is followed in the software development process.This above concept can also be started from the question. Hence True is the correct answer.How much time per day does the average U.S. youth spend watching television, playing video games, or using a computer?

In the past, dedicated networks are installed for separate voice, text and video packets. But as information technology evolves, one network is used for all three packets. This network is called convergent network.
In Python, create a calculator that will ask the user to input a single dimension of a shape and then display its properties.
E.g. Enter the radius of a circle; Display the circle’s Diameter, Circumference and Area
Only done for square and circle.
The code is given in the explanation section.
Explanation:
def areacalcpy():
_input_ = input("Enter the shape that you wish to calculate the area: ")
shapearea = 0
pieval = 3.14
if _input_ == "Square":
sideval = int(input("Enter side value of the shape: "))
shapearea = shapearea + (sideval ** 2)
elif _input_ == "Circle":
circleradius = int(input("Enter radius value of the circle: "))
shapearea = shapearea + (2 * pieval * circleradius)
else:
print ("The given shape is invalid, give a valid shape to calculate area")
print ("%.2f" % shapearea)
areacalcpy()
The given code can calculate the area for both the shapes circle and square.
Similarly the area can be calculated for triangle and rectangle.

Explanation:
Evidence-based decision-making uses research as the backbone for making decisions. It ensures that proper investigations are done before any decision is made.
This decision making technique carries out an in-depth analysis of empirical data collected from targeted sources. The decisions made are based on the following type of evidence:
Ethical evidence: research based on social justice to guide in making ethical decisions.Statistical modeling: using regression methods to make decisions in organizations.Impact evidence: making investigations based on the impact on others.Implementation evidence: considering the implementation and delivery success, after proper investigation.L.L. Bean works with the records of how quick customers make decisions and whether they complete their purchase. This means that they suggest solutions based on the evidence retrieved from the data.
You have a folder on your Windows desktop system that you would like to share with members of your development team. Users need to be able to view and edit any file in the share folder.
You share the folder and give Everyone Full Control permission to the shared folder. Users connect to the shared folder and report that they can open the files, but they cannot modify any of the file. What should you do?
Answer:
Modify the NTFS permissions on the folder.
Explanation:
While any user using a folder on his Ms Windows Operating System and he wanted to share that folder with his team members by which they can view and modify any file in that shared folder. Then, He has to provide Full Control permission to that folder by which they can only view that file but they cannot modify it.
So, He has to modify the NTFS permission on the following folder by which only those people can view that folder who has logged in over the server.
Final answer:
The problem with users being unable to modify files in a shared Windows folder can typically be resolved by adjusting the NTFS permissions on the files or folder to grant the correct level of access for editing. This involves ensuring that the necessary user groups have the 'Modify' permission set under the folder's Security properties.
Explanation:
If users can open files in the shared folder but cannot modify them, this suggests that the NTFS permissions on the files or the parent folder may not allow for modifications, despite the share permissions being set to Full Control for Everyone. Share permissions and NTFS permissions work together to provide the final level of access for a user. Since the issue at hand deals with users being able to read but not write or edit files, it's important to check the NTFS permissions.
To resolve the issue, you need to perform the following steps:
Right-click on the folder in question and select Properties.Go to the Security tab.Ensure that the group or usernames that need write access are listed and have the Edit permissions.If not, click on Edit to modify the permissions.Grant the appropriate users or groups the Modify permission or full control as needed.Apply the changes and ensure that the users are informed so that they can test the new permissions.By ensuring that both share and NTFS permissions are set correctly, you will enable your development team to view and edit files within the shared folder.

producing output before accepting input
subtracting when you meant to add
misspelling a programming language word
all of the above
Answer:
misspelling a programming language word
Explanation:
Syntax error is the type of error in programming, when the programmer insert some symbol that is not present in directories or libraries, the programmer not followed the rules of that particular programming language that is understandable to compiler.
For example in C++, it is necessary to insert the semicolon (;) after each statement. If the programmer not insert the semicolon after each statement, the program will show the syntax error.
If the programmer use integer instead of int to assign datatype to the variable in C++, it will also leads to the syntax error. Because in C++ library, Integer is defined with the help of "int".

Which of the following ANSI SQL queries would return only the name of the sales representative and the name of the customer for each customer that has a balance greater than 400?a. SELECT *
FROM SALESREP, CUSTOMER
WHERE Balance > 400;
b. SELECT DISTINCT RepName, CustName
FROM SALESREP, CUSTOMER
WHERE Balance > 400;
c. SELECT *
FROM SALESREP, CUSTOMER
WHERE SALESREP.SalesRepNo = CUSTOMER.SalesRepNo
AND Balance > 400;
d. SELECT RepName, CustName
FROM SALESREP, CUSTOMER
WHERE SALESREP.SalesRepNo = CUSTOMER.SalesRepNo
AND Balance > 400;
e. SELECT RepName, CustName
FROM SALESREP, CUSTOMER
WHERE Balance > 400
GROUP BY SalesRepNo;
Answer:
D. is the answer.
Explanation:
Since we need sales representative name and customer name, we should select only those columns.
Also we need to join the two tables with the common column i.e. "SalesRepNo", to get only the sales reps that have a sale and their corresponding cutomer(s).
Finally, we need to check for customer balance > 400 condition.

Tier I (core) capital includes at least some part of which of the following? I. Common stockholders' equity II. Retained earnings III. Subordinated debt IV. Allowance for loan and lease losses
Answer:
I and II only
Explanation:
Tier 1 capital is the core measure of a bank's financial strength from a regulator's point of view. It is composed of core capital, which consists primarily of common stock and disclosed reserves (or retained earnings) —that appears on the bank's financial statements, but may also include non-redeemable non-cumulative preferred stock.
Tier 1 capital is the assets the bank holds in its reserves in order to keep it functioning through all the risky transactions it performs, such as trading/investing and lending. Tier 1 capital includes common stock, retained earnings, and preferred stock.
Thus, Tier I (core) capital includes common stockholders' equity and retained earnings among the options.
Answer:
I. Common stockholders' equity II. Retained earnings
Explanation:
Tier 1 capital is a primary indicator of the financial power of a bank from authority's perspective. It is comprised of main assets, consisting primarily of common shares and declared assets, but can also contain un-redeemable un-cumulative preferred shares.
The core parts of equity capital are identified as the tier 1 capital: bonds, non-disposable balance sheets and retained income of shareholders, earned through the bank's lifetime. This reflects the capital sum which enables a bank to bear deficits without impacting depositors ' interest.

public class Window {
private int width, height;
public Window(int width, int height) {
this.width = width;
this.height = height;
}
public int getHeight() {
return height;
}
public void setHeight(int height) {
this.height = height;
}
public int getWidth() {
return width;
}
public void setWidth(int width) {
this.width = width;
}
@Override
public String toString() {
return "Window [width=" + width + ", height=" + height + "]";
}
}
TitledWindow.java:
public class TitledWindow extends Window {
private int barHeight;
public TitledWindow(int width, int height, int barHeight) {
super(width, height);
this.barHeight = barHeight;
}
public int getClientAreaHeight() {
return barHeight + super.getHeight();
}
@Override
public String toString() {
return "TitledWindow [width=" + super.getWidth() + ", height=" + super.getHeight() + ", barHeight=" + barHeight + "]";
}
}
TestWindows.java:
public class TestWindows {
public static void main(String args[]) {
Window w = new Window(450, 200);
System.out.println("Window: " + w);
TitledWindow titledWindow = new TitledWindow(450, 200, 30);
System.out.println("titaledWindow: " + titledWindow);
System.out.println("titledWindow.height: " + titledWindow.getClientAreaHeight());
}
