Based on experience, the time required to complete a college statistics exam is normally distributed with a mean of 42 minutes and a standard deviation of 8 minutes. The class is a large lecture and has 900 students. Simulate the exam completion times for the 900 students. (Convert to a percent then round to two decimals) a) What percent of students are still working when the professor stops the exam at 50 minutes

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

squares, rhombus, rectangles

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
