Question

Anais, a math teacher, noticed that the average grade on an exam, G, given that n students watch the related video can be given by the function G(n)=50+1.5n G(n)=50+1.5nG Find an explicit expression that gives the average grade on an exam if the related video is mmm minutes.

Answer 1

The explicit expression that gives the average grade on an exam if the related video is m minutes is G(m) = 50 + 1.5m.

Step-by-step explanation:

The average grade on an exam, given that n students watch the related video, can be determined using the function G(n)=50+1.5n.

To find the average grade on an exam if the related video is m minutes, we need to substitute m for n in the equation.

Therefore, the explicit expression that gives the average grade on an exam if the related video is m minutes is G(m) = 50 + 1.5m.
