<u>Your answer is 28x^2-37x+12</u>
<u>1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd</u>
28x^2-21x-16x+12
<u>2) Collect like terms</u>
28x^2+(-21-16x)+12
<u>3) Simplify</u>
28x^2-37x+12
The mean increases by 1.5 because every value is increased by 1.5, take this example.
{1, 3, 7, 9} has a mean of 5.
Add 1 to each value.
{2, 4, 8, 10} has a mean of 6.
Standard Deviation generally stays the same despite the change in values, because of it's equation is based on the mean and data values and the distance between them in the end do not change if ALL values in a data set increase/decrease by the same number.
