A large population of ALOHA users manages to generate 50 requests/sec, including both originals and retransmissions. Time is slo
krok68 [10]

Answer:

The answer is below

Explanation:

Given that:

Frame transmission time (X) = 40 ms

Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request

a) Probability that there is success on the first attempt = e^{-G}G^k but k = 0, therefore Probability that there is success on the first attempt = e^{-G}=e^{-2}=0.135

b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)

P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = [1-e^{-G}]^k=[1-0.135]^k=0.865^k

P(success in k+1 attempt) = e^{-G}=e^{-2}=0.135

Probability of exactly k collisions and then a success = 0.865^k0.135

c) Expected number of transmission attempts needed = probability of success in k transmission = e^{G}=e^{2}=7.389

Write a program that calculates the average rainfall for three months. The program should ask the user to enter the name of each
Eduardwww [97]

Answer:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

   Scanner input = new Scanner(System.in);

       System.out.println("Enter the month name:");

       String month1 = input.next();

       System.out.println("Enter the amount of rain for "+month1);

       double month1Rain = input.nextDouble();

       System.out.println("Enter the second month: ");

       String month2 = input.next();

       System.out.println("Enter the amount of rain for "+month2);

       double month2Rain = input.nextDouble();

       System.out.println("Enter the Third month: ");

       String month3 = input.next();

       System.out.println("Enter the amount of rain for "+month3);

       double month3Rain = input.nextDouble();

       double averageRainfall = (month1Rain+month2Rain+month3Rain)/3;

       System.out.printf("Average Rainfall is: %,.2f  ", averageRainfall);

   }

}

Explanation:

This is written in Java Programming language

  1. Import  the scanner class to prompt user for the inputs (Months and amount of rainfall for each month)
  2. Find the average of the three rainfall amount by adding up and dividing by 3
  3. Output the average. Pay particular attention to the use of java's printf in order to print the average to 2 decimal places

What were the technological innovations that allowed for the rapid expansion of the railroads?
liraira [26]

Answer:

There are different phases of railroad expansion with the innovations in technology.

Explanation:

Few of the technological innovations are described below that leads in railroad expansion more rapid.

1. Centralized Traffic control (CTC) is introduced in 1960's that is used to control the traffic on railroads using different signal control.

2. In 1990's after computer technology involvement, railway ticket and reservation system is automate and being centralized. That makes the railroad expansion improve.

3. Bullet train technology has been introduced, that makes the railway trains more faster.

4. Electric trains has been introduced to use green energy and reduce the dependency on the fuel to make environment clean and green.

String line = fileScanner.nextLine().trim();

//calculate the sum of first 5 digits

int sum = 0;

for(int i = 0; i < 5; i++) {

sum += Integer.parseInt( line.charAt(i) + "");

}

//Get the last digit

int lastDigit = Integer.parseInt(line.charAt(5)+"");

//Check if the remainder of the sum when divided by 10 is equal to last digit

if(sum%10 == lastDigit) {

//write the number in each line

fileWriter.write(line);

fileWriter.newLine();

System.out.println("Writing valid number to file: " + line);

}

}

System.out.println("Verifying valid numbers completed.");

} catch(IOException ex ) {

System.err.println("Error: Unable to read or write to the file. Check if the input file exists in the same directory.");
