If a rating has two 5s, and one 1, then what is the average?

Step-by-step explanation:

To find the average, add up all the ratings, then divide by the number of ratings.

μ = (5 + 5 + 1) / 3

μ = 11/3

μ ≈ 3.67

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
