Need asap the equation yˆ=−2.5x+222.5 models the amount of cholesterol, ldl , for a person, in mg/dl , where x is the time spent exercising per day, in minutes. according to the regression equation, what is the amount of cholesterol for a person exercising 20 minutes a day? a. 61.5 mg/dl b. 81.5 mg/dl c. 172.5 mg/dl d. 272.5.5 mg/dl

172.5 mg/dl

Step-by-step explanation:

Given the equation y= -2.5x + 222.5, where 'x' is the time spent exercising in minutes. If we want to know the amount of cholesteron for a person exercising 20 minutes a day, we just have to subtitute 20 into the equation for x.

So we have: y= -2x + 222.5 → y= -2.5(20 minutes) + 222.5 = 172.5 mg/dl
