What is the mean of the following numbers? 11,3,5,13

the mean is 8. add all the numbers then divide by the amount of numbers there are (in this case, 4.)

8

Step-by-step explanation:

3  5  11  13

3+5+11+13

32

32/4

8

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
