False, it's the other way around: you divide the numerator by the denominator.
For example, to evaluate
you divide 8 by 15:

Assuming the 2nd one is 4a^2 - 20a +25, it is the one you're looking for. It factors to be (2a-5)^2
Answer:
This is not really clear, I will assume that the values in the question are:
{0, 1, 0, 2, 3, 2, 3, 4}
For a set of N elements, {x₁, x₂, ..., xₙ}
The mean of the set is given by:

In the case of our set, {0, 1, 0, 2, 3, 2, 3, 4}, we have 8 values.
Then the mean of our set is:
