Box Plot Examples

The parts of a box plot is minimum, first quartile, median, third quartile, and maximum.

Parallelogram Area Formula

bh or b x h

Rectangle Area Formula

bh or b x h

Square Area Formula

bh or b x h

Quartile Range

scale divided into 4 equal parts

Range

subtracting the lowest value from the highest value

Diameter

A straight line passing from side to side through the center of a circle or sphere.

Volume Triangular Prism

(b x h divided by 2) x H

Median

1. Arrange the data points from smallest to largest. 2. If the number of data points is odd, the median is the middle data point in the list. 3. If the number of data points is even, the median is the average of the two middle data points in the list.

Volume Rectangular Pyramid

1/3 (L x W) times H

Volume Triangular Pyramid

1/3 (b x h divided by 2) x H

Inequalities - Examples

Example + steps of MAD

Mean Absolute Deviation

percent proportion

One ratio or fraction that compares part of a quantity to the whole quantity. The other ratio is the equivalent percent written as a fraction with a denominator of 100.

Mode

Put the numbers in order from least to greatest and count how many times each number occurs.

Rules of Multiplying and Dividing Integers rules

RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive. RULE 3: The product of two negative integers is positive.

Radius

The distance from the center of a circle to any point on the circle

distubitive property

The distributive property tells us how to solve expressions in the form of a(b + c)

Supplementary Angles

The sum of 2 angles that equal 180°

Complementary Angles

The sum of 2 angles that equal 90°

Rules of Adding and Subtracting Integers rules

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite

When do I flip an inequality sign?

When you multiply or divide both sides of an inequality by a negative number.

constant of proportionality

the constant ratio in a proportional linear relationship or y = kx

order of operations

the order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction

Adjacent Angles

two angles that have a common side and a common vertex (corner point) but do not overlap in any way.
