The mean of the values given is 6.5.
The mean in mathematics is found by finding the sum of all the values (adding the all together), then dividing the sum by the number of values there are.
If you add all the values given in the set above, you will get 65. There are 10 values, so you take 65 and divide it by 10. Thus getting 6.5 as your answer.
I hope this helps!

Answer:
<h2>440 square units</h2>
Step-by-step explanation:
We can find half of a side of the pentagon with the expression
Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.
Therefore, half of a side is 8 units long, which means each side measures 16 units.
Now, the area of a penthagon is defined by
Where 
is the perimeter and 
is the apothem. Where the perimeter is the sum of all sides, which is 80 units.
Therefore, the right answer is the second choice.
