Use the quadratic regression feature of a graphing calculator to find a quadratic model. round to the nearest thousdandths place.

Option d. 555.5

Step-by-step explanation:

The given regression equation is y = -0.008x² + 0.518x + 131.886

We have to predict the value of y if the x value is 200.

By putting x = 200 in the quadratic regression equation

y = 0.008(200)² + 0.518(200) + 131.886

y = (80 × 4) + (51.8 ×2) + 131.886

y = 320 + 103.6 + 131.886

y = 555.486 ≈ 555.5

Therefore, Option d. 555.5 is the answer.
