Probability and Statistics

Simplify means to do whatever can be done (add, subtract, multiply, or divide).

Quotient means divide. (Leave, change, flip!)

Use cross products to solve.

Percent of Change = Amount of Change/Original Amount

I = PRT (Interest = principal • interest rate • time)

The bigger the negative number, the larger/smaller its value... (which one is correct?)

I = PRT (if you can't multiply, DIVIDE!)
