Question

18. During the investigation of an archeological
dig, a femur bone was found and used to
estimate the height of the person it came
from using the formula h = 61.4+ 2.3F, where
h is the height, in centimeters, of a person
whose femur is F centimeters in length.
Using this formula, the height of the person
was estimated to be 5 feet 8 inches. The
length of the femur, in centimeters, was
closest to which of the following lengths?
[Note: 1 inch = 2.54 centimeters]
(A) 37.3
(B) 48.4
(C) 51.0
(D) 56.3​

Answer 1

length of the femur = 48.4 cm using formula h = 61.4+ 2.3F in investigation of an archeological

Step-by-step explanation:

h = 61.4+ 2.3F

h is the height, in centimeters, of a person whose femur is F centimeters in length.

h = 5 feet  8 inches

1 feet = 12 inches

=> 5 feet = 60 inches

5 feet  8 inches  = 68 inches

68 inches = 68 * 2.54 = 172.72 cm

h = 61.4+ 2.3F

172.72 = 61.4 + 2.3F

=> 2.3F = 111.32

=> F = 48.4

length of the femur = 48.4 cm
