To prepare for a job test, joan has to find the sum of 10 different scores for her friends, then divide by 10. which of these best describes what joan had to find? rate median mean mode

Joan had to find the mean.

The mean is a fancy word used to describe an average. When you add a series of numbers together and divide by the number of inputs, it gives you an average of them. Therefore, what she is finding is the mean.

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 !
