- In Exercises 107 and 108, use the following information. The relationship between the length of an adult’s femur (thigh bone) and the height of the adult can be approximated by the linear equations y=0.514x14.75 Female y=0.532x17.03 Male where y is the length of the femur in inches and x is the height of the adult in inches (see figure). A crime scene investigator discovers a femur belonging to an adult human female. The bone is 18 inches long. Estimate the height of the female.arrow_forwardIn Exercises 107 and 108, use the following information.
