Forensic scientists can determine the approximate height that a person was by measuring the length of the femur (thigh bone). They use a formula to calculate the person's height, based on the person's race and gender. The formula for a Caucasian female is given by: height = 2.47f + 54.13, where f is the length of the femur in centimeters. To the nearest centimeter, how many centimeters long is the femur of a female who is 168 centimeters tall? 469 centimeters 14 centimeters 90 centimeters 46 centimeters

The formula for a Caucasian female is given by: height = 2.47f + 54.13, where f is the length of the femur in centimeters.

assuming all caucasian female

height = 168 cmheight = 2.47f + 54.13168 = 2.47f + 54.13f = 46 cm

so the lenght of her femur is 46 cm
