luke is 5 feet 11 inches and weighs 170 pounds. using the body mass index chart as a guide, under which category would he fall? a. underweight b. normal c. overweight d. obese please select the best answer from the choices provided.

Explanation:

Step1: Convert height to inches

5 feet 11 inches = 5*12 + 11 = 71 inches.

Step2: Convert height to meters

1 inch = 0.0254 meters, so 71 inches = 71*0.0254 = 1.8034 meters.

Step3: Convert weight to kilograms

1 pound = 0.453592 kilograms, so 170 pounds = 170*0.453592 = 77.11064 kilograms.

Step4: Calculate BMI

BMI formula is $BMI=\frac{weight(kg)}{height(m)^2}$, so $BMI=\frac{77.11064}{1.8034^2}\approx23.7$.

Step5: Determine category

A normal - BMI range is typically 18.5 - 24.9. Since 23.7 is in this range, Luke is normal weight.

Answer:

B. normal
