Choose four numbers from the whole numbers 0 to 9, with repeats allowed that (a) have the smallest possible standard deviation.
(b) have the largest possible standard deviation.

what is the question?

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
