Example 8: Speed Dating Suppose that the height of male speed daters follows a Normal distribution with a mean of 70 inches and a standard
deviation of 3.5 inches and the height of female speed daters follows a Normal distribution with a mean of 65 inches and a
standard deviation of 3 inches. What is the probability that a randomly selected male speed dater is taller than the
randomly selected female speed dater he is paired with?

the answers c

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

2 over 5 and 4 over 15
