Question

Which of the following is an accurate assessment using the equation y = 0.625x - 27 to predict the number of minutes, y, it takes Khalil to check x emails, given that on Monday Khalil spent 25 minutes checking emails and on Tuesday he checked 35 emails?

A. Khalil spent less time than predicted on Monday and Tuesday.
B. Khalil spent more time than predicted on Monday and Tuesday.
C. Khalil spent the same amount of time as predicted on Monday and Tuesday.
D. The prediction cannot be assessed with the given information.

Answer 1

Khalil spent more time than predicted on Monday and Tuesday.

Step-by-step explanation:

To predict the number of minutes it takes Khalil to check emails, we need to substitute the given email counts into the equation y = 0.625x - 27.

For Monday, x = 25. Substituting into the equation, we have y = 0.625(25) - 27 = -11.625. So the predicted time is -11.625 minutes, which doesn't make sense.

For Tuesday, x = 35. Substituting into the equation, we have y = 0.625(35) - 27 = 7.375. So the predicted time is 7.375 minutes.
