Suppose the heights of women at a college are approximately Normally distributed with a mean of 66 inches and a population standard deviation of 2.5 inches. What height is at the 30th percentile?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
