Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Ex: If the input is: 15 20 0 5 -1 the output is: 10 20

Step-by-step explanation:

import java.util.Scanner;

public class LabProgram

{

  public static void main(String[] args) {

  Scanner sc = new Scanner(System.in);//to read input

  int count=0;//to keep track of the count of numbers entered

  int max=0;//to store the maximum value

  int sum=0;//to store the sum of numbers entered

  double av=0;//to calculate and store the average

  //reading inputs until a negative number is entered

  while(true)

  {

  int n = sc.nextInt();//reading input

  if(n<0)//if negative number

  break;//then stopping loop

  count++;//increasing count

  if(count==1)//means it is first number

  max=n;

  else if(max<n)//if current number is greater than previous max

  max=n;//updating max

  sum+=n;//adding new number to sum

  }

  //finding average

  av = (double)sum/count;

  //displaying output

      System.out.println((int)av+" "+max);//remove type casting (int) here, if you want decimal places also

  }

}

output:

15 20 0 5 -1

10 20

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
