Answer:
18.2
Step-by-step explanation:
A way we can find the average is by finding the mean.
Mean is found when you add up all the numbers and divide by the total amount of values there are.
In this case there are 5 values in total.
= 91/5 = 18.2

<h3>Answer: 32.5 units (choice C)</h3>
This value is approximate.
=============================================================
Explanation:
To find the perimeter, we simply add up the lengths of the three external sides.
The horizontal side from D to E is 16 units long since |-10-6| = 16. I subtracted the x coordinates of the points and applied absolute value. You could also count out the spaces and you should count 16 spaces from D to E.
Unfortunately, the diagonal lengths aren't as straight forward. We have two options here: The pythagorean theorem, or the distance formula.
I'll go with the distance formula.
Let's find the distance from C to D, aka the length of side CD
Side CD is roughly 9.2195 units long.
Repeat this idea to find the length of CE
Side CE is roughly 7.2801 units long
The perimeter of triangle CDE is approximately...
P = DE+CD+CE
P = 16 + 9.2195 + 7.2801
P = 32.4996
This then rounds to 32.5 units. The answer is choice C.
