What is the degree measure of FEG?
A 20°
B 31°
C 56°
D
124°

C) 56

Step-by-step explanation:

DEG and FEG are on a straight line forming 180 degree.

Set your formula up as

180 = (3x+31)+(2x-6)

180 = 3x +2x +31 - 6

180 - 31 + 6 = 5x

155 = 5x

155/5 = x

31 = x

Now substitute 31 in place of x

FEG = (2*31-6)

FEG = 56

a. 1

Step-by-step explanation:

Given : Population mean :

Standard deviation :

Let n be the number of times  a beach ball with a diameter of 26.7 cm differ from the mean.

Then, we have

Hence, a beach ball with a diameter of 26.7 cm is 1 standard deviation differ from the mean.
