A factory process requires 3 steps to finish a product. The steps each have a mean completion time of u= 10 seconds and a standard deviation of o = 5 seconds. The time it takes to complete each step is
independent from the other steps. Let T be the total completion time of the 3 steps on a randomly chosen
product.
Find the mean of T.
μY T =
seconds

Step-by-step explanation:

17seconds

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.
