8. The average annual rainfall for a town is 43.2 inches.
a. What is the average monthly rainfall?
b. The difference of a given month’s
rainfall from the average monthly
rainfall is called the deviation. What is
the deviation for each month shown?

c. The average monthly rainfall for the
previous 9 months was 4 inches. Did
the town exceed its average annual
rainfall? If so, by how much?

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
