**Data Analysis**

__line plot__: A number line with marks or dots **that show frequency.**

__scatter plot__: A graph with points plotted to **show a possible relationship between two ****sets of data.**

__stem-and-leaf plot__: A graph used to organize **and display data so that the frequencies can ****be. **

__circle graph__: A graph that uses sectors of a **circle to compare parts to the whole and parts ****to other parts.**

__frequency table__: A table that lists items **together according to the number of times, or ****frequency, that the items occur. **

__line graph__: A graph that uses line segments **to show how data changes.**

**Probability**

__combination__: An arrangement of items or events in which order does not matter.

__dependent events__: Events for which the **outcome of one event affects the probability ****of the second event.**

**experimental ****probability****: The ratio of the ****number of times an event occurs to the total ****number of trials, or times that the activity is ****performed.**

**independent events****: Events for which the ****outcome of one event does not affect the ****probability of the other.**

**Algebra-Solving Linear Equations & Inequalities**

__equivalent expression__: Equivalent **expressions have the same value for ****all values of the variables. 4x 5x and 9x are equivalent expressions. **

**like terms: Two or more terms that have the** same

**variable raised to the same power.****In the expression 3***a***5***b***12***a*, 3*a*and 12*a*are like terms.
__simplify__: To write a fraction or expression in **simplest form. 6/8 = 3/4**

__solution of a system of equations__: A set **of values that make all equations in a ****system true. **

__permutation__: An arrangement of items or **events in which order is important. ABC, ACB, BAC, BCA, CAB, CBA.**

__probability__: A number from 0 to 1 (or 0% to **100%) that describes how likely an event is ****to occur.**

__simulation__: A model of an experiment, often **one that would be too difficult or too time consuming ****to actually perform.**

**t heoretical probability: The ratio of the **

**number of equally likely outcomes in an event**

**to the total number of possible outcomes.**

**A bag contains 3 red**

**marbles and 4 blue**

**marbles. The probability of**

**randomly choosing a red**

**marble is 3/7.**

**When rolling a number**

**cube, the theoretical**

**probability of rolling a**

**4 is 1/6**

**.**

__binomial__: A polynomial with two terms.

__degree of a polynomial__: The highest power of **the variable in a polynomial.**

__monomial__: A number or a product of numbers **and variables with exponents that are whole ****numbers.**

__polynomial__: One monomial or the sum or **difference of monomials.**

__trinomial__: A polynomial with three terms.

__origin__: coordinate point (0,0). Where you begin on the coordinate plane to graph coordinate points.

__slope__: the steepness of a line (__rise__)

** run**

__y intercept__: where the line crosses on the y axis

__y=mx + b__ : slope intercept formula for a line

__domain__: the input, x

__range:__ the output, y

__coordinate point__: odered pairs or the x and y coordinates on a coordinate plane
