I would say B. The mean is a good measure of central tendency.
I hope this helps!
Answer:
0.8
Step-by-step explanation:
-8.1+8.9=0.8
so the answer is 0.8
The perimeter = 4 * length of a semicircle of radius 5 == 4* pi * 5 = 20 pi cm
The area of one of the clear parts = 1/2 area of square - area semicircle
= 1/2 * 10^2 - 1/2 pi *5^2 = 50 - 12.5pi
So area of shaded parts = area of square - 4 (50 - 12.5pi)
= 100 - 200 + 100pi = (100pi - 100) cm^2
Range is 6 and the mode is 8
