an integer greater than zero

an integer less than zero

The set of whole numbers, their opposites, and zero

The distance a number is from zero on a number line

For any number x, there exists a number −x, such that x + −x= 0.

The multiplicative inverse of a number

A decimal number that ends or terminates

A decimal that repeats a digit or group of digits forever.

The number by which another number is divided.

Two numbers with a product of 1

A rate in which the second quantity in the comparison is one unit

having the same value

A relationship between two quantities in which the ratio of one quantity to the other quantity is constant.

An equation stating that two ratios are equal

the difference between the actual value and the estimated value compared to the actual value and is expressed in a percentage format

If a function has a rule in the form y= Kx, then for any input x≠0, the quotient of y/x will always have the value K. The number K is called constant of proportionality.

An equation that describes the relationship between the part, whole, and percent.

A figure that is made up of two or more figures.

percent increase or decrease from the original amount

the difference coming after subtracting the old value from the new value and then divide by the old value and the final answer will be multiplied by 100 to show it as a percentage

Interest earned only on the original principal amount invested or borrowed I=Prt

an expression that contains at least one variable

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

The numerical value of the ratio of the circumference of a circle to its diameter of approximately 3.14159.

A symbol used to represent a quantity that can change

A number multiplied by a variable in an algebraic expression.

the perimeter of a circle, πd or 2rπ

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

The value of the variable that makes the equation true.

a variable without a coefficient is understood to have a coefficient of 1.

two angles whose measures have a sum of 180 degrees

A pair of opposite congruent angles formed by intersecting lines

Terms that contain the same variables raised to the same power.

Numbers that are multiplied together to get a product

To get a variable alone on one side of an equation or inequality in order to solve the equation or inequality

Two angles that share a common side and have the same vertex

two angles whose measures have a sum of 90 degrees

the number of times an event occurs divided by the total number of events occurring in a given scenario

operations that undo each other

a drawing that uses a scale to represent an object as smaller or larger than the original object

When both sides have the same quantity

any subset of the sample space

A statement that compares two quantities using <, >, ≤,≥, or ≠

Probability that is based on repeated trials of an experiment

lists the possible outcomes of a probability experiment and each outcome's probability

a sample that fairly represents a population because each member has an equal chance of inclusion

randomly selected sample of subjects from a larger population of subjects

The possible results of an experiment

Probability based on comparing the number of possible favorable outcomes to the number of total possible outcomes

A statement that is true about the population. It is based on data from a representative sample.

a graphic way of showing a summary of data using the median, quartiles, and extremes of the data

in a set of numbers, how widely dispersed the values are from each other and from the mean

likelihood that a particular event will occur

each of four equal groups into which a population can be divided according to the distribution of values of a particular variable.

mean, median, mode

The difference between the upper and lower quartiles.

the average distance between each data value and the mean

A measure of space; the number of unit cubes needed to fill a three-dimensional shape.
