Users of a mobile application are categorized based on the average number of hours they use the application each day, as shown in the following table.   Mobile Number Users Category Average Hours of Use Per Day Top User Greater than 5 Regular User Between 1 and 5, inclusive Inactive User Less than 1     Suppose n is the average number of hours a user spends using the application each day. Which of the following algorithms can be used to assign the correct categorization to a user?

Consider the following code segment, which is intended to print true only when both r and v are positive numbers. Assume that r and v have been properly declared and initialized.   boolean rPos = r > 0; boolean vPos = v > 0;System.out.print(rPos == vPos);    The code segment does not always work as intended.   Which of the following values for r and v will demonstrate that this code segment does not work as intended?

In the following code segment, n is a properly declared and initialized int variable.     boolean result = false; if (n >= 10){ result = true;}if (n

What is the output of the following code segment?   for (int k = 5;  k > -5; k–){  System.out.print( k + ” ” );}System.out.println( );

A certain device requires a passcode to be used. The passcode must meet both of the following requirements.   • The passcode must be 4 digits long. • The passcode must not start with a zero (0) digit.   Assume that pass is a properly declared and initialized int variable.   Which of the following expressions will evaluate to true if pass is an acceptable passcode?
