**Math**

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. a. 2 * -9 = -9 + -9 = -18 d. 7 * 0 = 0 Use process in a to solve b and c.

**Statistics**

Is Z = +1 the same as the mean? That should give you the answer.

**STATS**

Z = (score-mean)/SD Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability (.025) related to the Z score. Insert Z and other values into above equation.

**math 3**

P(red) = 2/(4+2+6) = ? If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. P(red) * P(red) = ?

Here is the process. It doesn't fit with the above answer. m = j + 17 m + j = 49 Substitute j+17 for m in second equation and solve for j. Insert that value into the first equation and solve for m. Check by inserting both values into the second equation.

**Algebra**

a. Best = y = 40 + .10x A+ = y = 35 + .20x b. Calculate y when x = 500. c. 40 + .10x = 35 + .20x Solve for x.

**Algebra**

Substitute the value for x and solve the equation for S. S = 50(14) + 450 = 700 + 450 = 1150 Do the same for the other values.
