67. Forensic scientists use the lengths of certain bones to calculate the height of a person. Two
bones often used are the tibia (f), the bone from the ankle to the knee, and the femur (r), the
bone from the knee to the hip socket. A person's height (h) is determined from the lengths
of these bones by using functions defined by the following formulas. All measurements are
in centimeters.
Or
For men: h(r) = 69.09 + 2.24r ог h(t)= 81.69+2.39t
For women: h(r) = 61.41 + 2.32r
h(t) 72.57 +2.53t
