Magazine Problem 5
Archaeologists and forensic scientists use the length of human bones to
estimate the height of individuals. A person's height, \(h\), in centimeters can
be determined from the length of his/her femur, \(f\) (the bone from the knee to
the hip socket), in centimeters using the following formulas:
$$\text { Male: } h=69.089+2.238 f$$
$$\text { Female: } h=61.412+2.317 f$$
a. A partial skeleton of a male is found. The femur measures 50 centimeters.
How tall was the man?
b. What is the length of the femur for a female who is 150 centimeters tall?

Problem 6
The recommended weight for an adult male is given by the formula
\(w=\frac{11}{2} h-220,\) where w represents the recommended weight in pounds
and \(h\) represents the height of the person in inches. Determine the height of
an adult male whose recommended weight is 165 pounds.
