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?

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

you probably already have the answer but anyways it's b. 15.0
