The equations below express the relationship between a person's height, H, and femur (thigh bone) length, F. Both measurements are in inches.
Males : H=27.5+2.24F
Females: H=24+2.32F

a) If a man's femur is 20 inches long, about how tall is he?
b) If a woman's femur is 15 inches long, about how tall is she?
c) If a man is 65 inches tall, about how long is his femur?
d) If a woman is 68 inches tall, about how long is her femur?
e) What do the numbers 2.24 and 2.32 tell you about the relationship between femur length and height for males and females?

Just plug in your numbers.
(a) H = 27.5 + 2.24*20
(d) 68 = 24+2.32F
(e) as femurs lengthen, men grow more slowly
