A Number Coefficent is a number that multiplies the variables.

Variable:

A Variable is a letter that represents an unknown number.
 Expression:

An Expression is any single number or variable combination of operation ( -, +, x, ./.) involving a number.

 Math review:
Constant - a number that does not change and it increases or decreases the value of an expression

Math Notes:

Random- An event in which every outcome has an equal chance of happening.

eg. Flipping a coin, Rolling a standard die, drawing a card from a deck of cards

Exam review:

Experimental probability: The probability of an event occurring based on experimental results

Theoretical probability: The expected probability of an event occurring *STUDY*

Exam notes:

Range: the positive difference, the largest and smallest in a data set

Exam review: Measures of central tendency

-A value that repesents the center of a data set
- Can be the Mean, Median, or Mode
-Data set is a group of numbers that you must arrange from least to greatest
