Question

There's a roughly linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height. Within a certain population, this relationship can be expressed using the formula h=2.35f+54.7h, where h represents the expected height in centimeters and ff represents the length of the femur in centimeters. What is the meaning of the ff-value when h=149h

Answer 1

The ff-value represents the length of the femur in centimeters when the expected height is 149 centimeters.

Step-by-step explanation:

The given formula h = 2.35f + 54.7 represents a linear relationship between the length of someone's femur (f) and their expected height (h) in a certain population.

To find the meaning of the ff-value when h = 149, we can substitute h = 149 into the formula and solve for f:

149 = 2.35f + 54.7

2.35f = 149 - 54.7

2.35f = 94.3

f = 94.3 / 2.35

f ≈ 40.13

Therefore, when the expected height is 149 centimeters, the length of the femur is approximately 40.13 centimeters.
