The answer would C. You must remember for the mean you need to add up all of the numbers, then divide the answer by the number of numbers you have.
Ex:
5,3,7,2,1
All of these numbers added up together is 18.In order to find out the mean, we need to divide the answer(18) by 5 because there are 5 numbers.
Hope this helps!

Given:
Consider the pentagon MVEDR is dilated with the origin as the center of dilation using the rule  to create pentagon M'V'E'D'R'.
 to create pentagon M'V'E'D'R'.
To find:
The correct statement.
Solution:
If a figure dilated by factor k, then the rule of dilation is

Here, 
If k>1, then the image is larger than the original figure.
If k<1, then the image is smaller than the original figure.
We have,

Here, M'V'E'D'R' is image and MVEDR is original figure. The scale factor is

Pentagon M'V'E'D'R' is smaller than pentagon MVEDR because the scale factor is less than 1.
Therefore, the correct option is B.
