a. When circuit switching is used, only one user can be supported on a 2 Mbps link, since each user continuously transmits at 1 Mbps.

b. If two or fewer users transmit at the same time with packet switching, there will be essentially no queuing delay before the link.

c. The probability that a given user is transmitting is 20 percent, since each user transmits only 20 percent of the time.

d. If there are three users, the probability that all three users are transmitting simultaneously is 0.008.

Circuit switching creates a dedicated connection between two nodes for the duration of a transmission, meaning that only one transmission can take place at a time on a single link.

The fraction of time during which the queue grows is equal to the probability that all three users are transmitting simultaneously, since this is the only time when the incoming traffic will exceed the link's capacity. In this case, the fraction of time during which the queue grows is 0.008.

The probability that all three users are transmitting simultaneously is

A foreign key must match a primary key or be null in order to maintain referential integrity. Because it is given between parent and child tables, this constraint maintains the relationship between the rows in both.

An attribute is said to be derived if its value can be inferred from the values of other attributes, in which case it is said to be derivable. For instance, age can be derived if we have an attribute for birthdate.

Answer: With the criteria you have listed, here's the code.

import java.util.Scanner;

public class CaloricExpenditure {

 public static void main(String[] args) {

   Scanner scan = new Scanner(System.in);

   System.out.print("Enter the number of hours spent bicycling: ");

   int hoursBicycling = scan.nextInt();

   System.out.print("Enter the number of hours spent jogging: ");

   int hoursJogging = scan.nextInt();

   System.out.print("Enter the number of hours spent swimming: ");

   int hoursSwimming = scan.nextInt();

   int totalCalories = (hoursBicycling * 200) + (hoursJogging * 475) + (hoursSwimming * 275);

   double poundsLost = totalCalories / 3500.0;

   System.out.println("You have burned a total of " + totalCalories + " calories.");

   System.out.println("This means you have lost " + poundsLost + " pounds.");

 }

}

Explanation:

The Scanner class is used in this software to ask the user to enter how many hours they spent doing each activity. The total amount of calories burned is then determined by dividing the caloric expenditure of each activity by the quantity of time spent engaging in that activity. The total amount of calories burned is then divided by 3500 to determine the number of pounds lost. The user sees the outcome in the console.

The output of the code snippet, assuming the user inputs 25 for the price and 10 for the discount rate, is 22.5.

This is because the new price is calculated by subtracting the discount rate (10%) from the original price (25). Therefore, the new price is 25 - (25 * (10 / 100.0)) = 22.5.

It is also important to note that the discount rate should always be expressed in terms of a percentage, as this makes it easier to calculate the discounted amount and the amount saved. Additionally, it is important to remember that the discount rate should always be expressed as a decimal, as this is the form used in calculations.

This indicator may appear in a variety of situations, although DDoS attacks are frequent. Such an assault is indicated by a significant number of RST and ACK flags.

It is also commonly used for developing large-scale software systems, as it provides a high level of control over system resources and can handle complex data structures with ease.

It is difficult to determine the exact output without the complete code, but here's a sample response to fill in the blanks:

polyFunc(x, y) = __

polyMacro(x, y) = __

In VS: the result of polyFunc = 36 and polyMacro = 36

In GCC: the result of polyFunc = 36 and polyMacro = 36

Explanation: The reason for the difference in output could be due to the different implementation of the C++ standard library and the compiler optimization settings used by VS and GCC.

To ensure that polyFunc and polyMacro produce the same output of 36, you need to edit the code. Here's one possible way to do this:
