Answer:
25%
Step-by-step explanation:
20/80 in can be reduced to 1/4 and 1/4 equals 25%.
I would say division, you are trying to see how many cans can fit on those 15 shelves so you should do 585/15.
Why not look up "standard deviation" yourself, to be sure? But yes, the std. dev. is the sqrt of the variance.
your answer is (1,3) but positive
Plug in -1 for x and work it ou'
g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8
= -1 + 6 - 12 + 8
= 1
