Best Answer

You can calculate standard deviation by addin the numbers of data that are together and dividing that number by the amount pieces of data.


What was answered above was the calculation for getting an (mean) average.

If you take five numbers for example 1, 2, 3, 4, 5 then the (mean) average is 3.

But the standard deviation between them is 1.58814 and the variance is 2.5

Also the population std. deviation will be 1.41421 and the population variance will be 2.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
