Answer

To find mean of data add all the numbers in the set of data and divide the sum by the number of addends.

To find range, identify the difference between the highest value and lowest value in the set of data.

Explanation

Mean, mode, median and range are the primary measurements used to get the measures of central tendencies. To get the mean and range; first arrange the data in an ascending order, then identify the highest value and the lowest value in the set. The difference between these two data values gives the range of the set of values. For the mean, add all the set of values and then divide their sum with the number of values in the set of data.

Write a for loop that computes the following sum: 5+10+15+20+...+485+490+495+500. The sum should be placed in a variable sum tha
Strike441 [17]

Answer:

public class num9 {

   public static void main(String[] args) {

       int sum =0;

       int num =5;

       for(num =5; num<=500; num+=5){

           System.out.println(num);

           sum +=num;

       }

       System.out.println(sum);

   }

}

Explanation:

  • Declare and initialize the variables sum and num
  • Use a for loop with the condition for(num =5; num<=500; num+=5) Since the loop will increment by 5 and run from 5 to 500
  • Within the loop, add num to sum at each iteration
  • Print all elements on seperate lines
  • Outside the loop, print the final value of sum

Answer:

Code is given below and output is attached as an image.

Explanation:

#include <iostream>

#include <fstream>

using namespace std;

bool isPalindrome(int n)

{

       // Find reverse of n

       int rev = 0;

       for (int i = n; i > 0; i /= 10)

               rev = rev * 10 + i % 10;

       // If n and rev are same,then n is a palindrome

       return (n == rev);

}

int main()

{

       int min = 1;        // Lower Bound

       int max = 200;      // Upper Bound

       ofstream myfile;

       myfile.open("palindrome.txt");

       for (int i = min + 1; i < max; i++)

               if (isPalindrome(i))

                       myfile << i << endl;

       myfile.close();

       return 0;

}
