Answer:
70 miles /hour = r
Step-by-step explanation:
d=rt
Substitute d=350 miles and t = 5 hours
350 miles = r* 5 hours
Divide each side by 5 hours
350 miles = 5 hours = r
70 miles /hour = r
The correct answer is: <span>D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )</span>
