Answer:
option C 13.5%
Step-by-step explanation:
As the heights of adults is normally distributed with mean=69 and standard deviation=2.5 so, the percent of men that are between 64 and 66.5 inches tall can be calculated as
P(64<X<66.5)=P[ (64-69)/2.5<(X-μ)/σ<(66.5-69)/2.5]
P(64<X<66.5)=P(-2<Z<-1)
P(64<X<66.5)=P(-2<Z<0)-P(-1<Z<0)
P(64<X<66.5)=0.4772-0.3413=0.1359
Thus, the percent of men are between 64 and 66.5 inches tall is 13.59%.
If we round the resultant quantity then it will be rounded to 13.6% but considering the given options, option C is most appropriate.

Answer:
<h2>3</h2>
Step-by-step explanation:
<h3>Step 1: Identify two points on the line</h3>
1,2 & 2,5
<h3>Step 2: Select x1, y1 & x2, y2</h3>
x1 = 2, y1 = 5 x2 = 1, y2 = 2
<h3>Step 3: Use the Slope Formula</h3>
change y/ change x
<u><em>IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.</em></u>
Y 5 -2 = 3
X 2 - 1 = 1
3/1 = 3
