Answer: The answer is D: can be viewed on a screen.

Compared to a virtual image, a real image can be viewed on a screen.

Explanation:

A real image refers to an image that is formed when there is a meeting point between rays of light coming from an object after reflection. An example is the image seen on the cinema screen.

A virtual image refers to an image that is formed when there is no actual meeting point between rays of light coming from an object but they appear to meet when produced backwards. An example is the image seen in the mirror when standing in front of the mirror.

olchik [2.2K]

Here is code in java.

import java.util.*; // import package

class Main //  creating class

{

public static void main (String[] args) // main method

{

Scanner br=new Scanner(System.in); // scanner class for input

       int []a=new int[20]; // declaring array

       int count=0,x,j; // creating variable

       int sum =0;

       System.out.println("Enter a weight (0 to stop):");

       x=br.nextInt(); // taking input

while(x!=0) // iterating over the loop

       {

           a[count] = x;

           count++;

           System.out.println("Enter a weight (0 to stop):");

           x=br.nextInt();

}

       for( j=0;j<count;j++) // iterating over the loop

       {

       sum+=a[j];

       }

       double avg = sum/(double)count;

       System.out.println("The total is: "+sum);

       System.out.println("The average is: "+avg);

       System.out.println("Here are all the numbers less than the average: ");

     for( j=0;j<count;j++) //  // iterating over the loop

       {

           if(a[j]<avg)

           System.out.print(a[j]+" ");

       }

}

}

Explanation:

First create an object of "Scanner" class to read input from the user.

Create an array of size 20, which store the number given by user.Ask user

to give input and keep the count of number in the variable "count". If user

give input 0 then it will stop taking input.And then calculate sum of all the

input.It will calculate average by dividing the sum with count and print it.

It will compare the all elements of array with average value, if the element

is less than average, it will print that element.

Output:

Enter a weight (0 to stop):

1

Enter a weight (0 to stop):

2

Enter a weight (0 to stop):

3

Enter a weight (0 to stop):

4

Enter a weight (0 to stop):

5

Enter a weight (0 to stop):

6

Enter a weight (0 to stop):

7

Enter a weight (0 to stop):

8

Enter a weight (0 to stop):

9

Enter a weight (0 to stop):

10

Enter a weight (0 to stop):

0

The total is: 55

The average is: 5.5

Here are all the numbers less than the average:

A bakery collects data on sales. Each sales record includes the date of the sale and some metadata about the items that were par
professor190 [17]

Answer:

B. Which customer most frequently purchases bread.

Explanation:

As per the scenario, the data we are receiving from the sales record of the bakery is :

The date on which the items are sold

Each items name which are sold

The number of each item sold and

The price of each item sold  

These data are required to estimate how much the company has earned the profit during a given period of time.

So from the above scenario, there is no data given about the customer i.e customer name, customer number, etc. So there is no chance to track the details of a customer purchase history.

Therefore, the most appropriate answer is option B
