Suppose that you add 10 to all of the observations in a sample. how does this change the sample mean? how does it change the sample standard deviation?

The sum of ten and the quotient of a number x and 6.

Which shows the equation y + 2 = 3 (x - 2) written in standard form A: y - x - 3 = 0 B: y=3x C: y = x + 3 D: y - 2 = x + 3

B2 - 4ac > 0 means the root is real. True or False
