Mean = 0.53*23.7% + 0.25*12.7% + 0.22*(-0.112)= 15.71%
standard deviation= sqrt(0.53*(23.7%-15.71%)^2 + 0.25*(12.7%-15.71%)^2 + 0.22*(-0.112-12.40%)^2)= 8.40%

Answer:
98.8 cm²
Step-by-step explanation:
Hi there!
where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)
<u>1) Find the perimeter</u>
where l is the side length
Plug in the side length 7.6 cm

Therefore, the perimeter of the pentagon is 38 cm.
<u>2) Find the area</u>
Plug in the perimeter (38) and the apothem (5.2)

Therefore, the area of the pentagon is 98.8 cm².
I hope this helps!
