Answer with explanation:
1.Mean of a Data set


2. Range = Maximum value in two conferences - Minimum value in two conference
= 12 - 0
=12
The mean number of wins for teams from the two conferences is 7.65.
The range in wins is 12.
14/20
14/18

The length of each side of octagon is 1.66 inches.
The given equation is,

Thus, option (C) is the correct solution.
Using law of cosines:
Cos(angle) = adjacent/ hypotenuse
Cos(22) = 12/x
Rewrite to get:
X = 12/cos(22)
Simplify:
X = 12.9424
Round the answer as needed.
