I have to solve this by setting up a proportion using either one of these theorems: 1. When an altitude is drawn to the hypotenuse of a right triangle, then the altitude is the geometric mean between the parts of the hypotenuse. (Part-altitude-altitude-part) Or 2. When an altitude is drawn to the hypotenuse of a right triangle, then each original leg is the geometric mean between the hypotenuse and the part of the hypotenuse adjacent to the leg. (Part-leg-leg-whole)

Suppose that a company must service customers lying in an area of A square miles with n warehouses. Kolesar and Blum showed that when the warehouse(s) are located properly, the average distance between a warehouse and a customer is (????)12. Assume that it costs the company $90,000 per year to maintain a warehouse and $5,000,000 to build a warehouse. Also, assume that this $5,000,000 building cost is equivalent to incurring a cost of $500,000 per year indefinitely. The company fills 180,000 orders per year, and the shipping cost per order is $1.25 per mile.

Based on the result, is 1 girl in 10 births a significantly low number of girls? Explain. A. Yes, 1 girl is a significantly low number of girls, because 1 girl is below the range of values that are not significant. B. No, 1 girl is not a significantly low number of girls, because 1 girl is within the range of values that are not significant. C. Yes, 1 girl is a significantly low number of girls, because 1 girl is above the range of values that are not significant. D. Not enough information is given.
