Experimental probability- actually doing the trails
Theoretical probability- what you expect to happen  

Transformations

Transformations 
Translation- slide along a straight line
Rotation- turn about a fixed point
Reflection- mirror image

Divisibility Rules

Divisibility - means when a number can be divided by another number, with no remainder or decimal

it is a whole number

Divisibility Rules

 0- end in a zero
1-  all numbers
2- eve numbers
3- sum of the digit is 3
4- divisible by 2 twice
5- ends in a 0  or 5
6- divisible by 2 and 3
8- divisible by 2 twice
9- sum of the digits is 9
10- ends in a zero

Quadrant

(+,+) quadrant |
(-,+) quadrant ||
(-,-) quadrant |||
(+,-) quadrant |V

describe the horizontal and vertical movements between two points, 2 units right and 3 units left.

Mean, Median, Mode, Range, Outlier.

Mean- add up all values divided by how many values there are
Median- the middle number in a set of ordered values, might be the mean of a middle values
Mode- the value that shows up the most
Range- positive difference between largest and smallest values
Outlier- values that are too big or too small compared to the other values
Variable is an unknown number
expression contains variables, operation, and numbers in an combination.

Practice finding the pattern
eg: 24,21,18,15
and write equations for the pattern
eg: 27-3t=n
T=term
