Question

the formula for calculating your bmi is below. bmi = 703 (weight in pounds) / (height in inches)^2. which line of code will correctly calculate the bmi? select 3 options. bmi = 703 weight / (height height) bmi = 703 weight / height height bmi = (703 weight) / height * 2 bmi = 703 weight / height * 2 bmi = 703 weight / height ^ 2

Explanation:

Step1: Recall the BMI formula

The formula is $BMI = 703\times\frac{\text{weight in pounds}}{(\text{height in inches})^2}$. In code, height squared can be written as height height or height * 2.

Step2: Analyze each option

• Option 1: bmi = 703 weight / (height height) is correct as it follows the formula.
• Option 2: bmi = 703 weight / height height is incorrect because in the order of operations, division and multiplication are done from left - to - right. This will not calculate height squared in the denominator as required.
• Option 3: bmi = (703 * weight) / height 2 is correct. height 2 represents height squared and the overall expression follows the formula.
• Option 4: bmi = 703 weight / height * 2 is correct as it is equivalent to the formula.
• Option 5: bmi = 703 * weight / height ^ 2 is incorrect as in most programming languages, ^ is the bitwise XOR operator, not the exponentiation operator.

Answer:

• bmi = 703 weight / (height height)
• bmi = (703 weight) / height * 2
• bmi = 703 weight / height * 2
