Answer:
Option C.
Step-by-step explanation:
For a given set of N elements:
{x₁, x₂, ..., xₙ}
The mean is given by:

And the variance is given by:

Then for our set:
{70, 80 ,75, 75, 80}
We have 5 elements, then N = 5
The first thing we need to find is the mean.

Then the variance will be:

The correct option is C, 14.
The solution to the equation is y = 5.5 + x , for any real number x greater than or equal to zero and y any real number greater than or equal to 5.5.
Analysis:
since number of items cannot be negative x and y are real number numbers since y or x can be a decimal so we do not use integers alone.
so y = 5.5 + x , for any real number x greater than or equal to zero and y any real number greater than or equal to 5.5.
