Question

the formula w = 0.00189h^{2.63} is used to estimate the normal weight w of a boy h inches tall. find the expected weight of a boy who is 45 inches tall. the expected weight of the boy is approximately lb. (type an integer or a decimal rounded to the nearest tenth as needed.)

Explanation:

Step1: Substitute height value

Substitute $h = 45$ into $w=0.00189h^{2.63}$. So $w = 0.00189\times45^{2.63}$.

Step2: Calculate $45^{2.63}$

Using a calculator, $45^{2.63}\approx1599.47$.

Step3: Calculate weight

$w=0.00189\times1599.47\approx 3.0$.

Answer:

$3.0$
