Answer:
The answer is in the photo.
Step-by-step explanation:
Slopes are represented using:
y = mx + b
_______
m - the slope, represented by a fraction or whole number
x - x, don't plug in the x-value
b - where you start on the y-axis
_______
On the left is the original slope. You apply the same slope to (5,-1). You don't have to apply the b.
So, all you have to do is start at (5,-1) and apply the angle, going up 8 and right 3.

Answer:
The 99th percentile for a man’s arm span is 80.47 inches.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
99th percentile
X when Z has a pvalue of 0.99. So X when Z = 2.327.
The 99th percentile for a man’s arm span is 80.47 inches.
