Answer:

D. y= 555.5

Step-by-step explanation:

We are given,

The quadratic regression equation is $y=0.008x^2+0.518x+131.886$

It is required to predict the y-value, when the x-value is 200.

Substituting x= 200, we get,

$y=0.008x^2+0.518x+131.886\\\\y=0.008\times 200^2+0.518\times 200+131.886\\\\y=0.008\times 40000+0.518\times 200+131.886\\\\y=320+103.6+131.886\\\\y=555.5$

<h3>Thus, the predicted y-value is 555.5 when x= 200.</h3>

So, option D is correct.

The answer would be D: y=555.5, because y for x=175 is 470.4, and y goes up with the x.
