Answer:
118 degrees
Step-by-step explanation:
A line has an angle of 180 degrees, so to find the unknown angle of b just subtract the known angle from 180.
180 - 62 = 118
The answer is .6666666667
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
