An 8th grade class develops a linear model that predicts the number of cheerios (a small round cereal) that fit on the

circumference of a plate by using the diameter in inches. Their model is $\hat{\text{cheerios}}$ = 0.56 + 5.11(diameter).

-If the diameter is increased from 4 inches to 14 inches, the predicted number of cheerios will Increase by about……
A) 21
B) 72
C) none of these
D) 51
E) 10

Quizplus · Accepted Answer

The increase in diameter is 14 inches - 4 inches = 10 inches. Using the model, the increase in the predicted number of cheerios is 5.11 * 10 = 51.
