| Question | Answer |
|---|---|
| something that follows a particular rule | mathematical pattern |
| symbol that represents an unknown number | variable |
| fixed quantity that cannot change | constant |
| a number that multiplies a variable ex: 5y | coefficient |
| a string of numbers, mathematical operations, and an equal sign that tells you a math fact | number sentence |
| >,<...instead of = | inequalities |
| mathematical phrase that may include numbers, variables, and operators basically like a sentence | algebraic expression |
| constants, variables, and products of constants and variables | terms |
| individual terms that have the same variable | like-terms |
| the process of simplifying expressions by joining terms that have the same variable | combining like-terms |
| the steepness of a line; measures steepness of objects | slope |
| y=m x + b m=slope (if no number, then slope=1); b= y-intercept | equation of a line |
| a set of descriptive measures that indicate the typical score | measures of central tendency |
| the average | mean |
| "most often"; 2 or more numbers occurring at the same time (so report both) | mode |
| the complete collection to be studied | population |
| a section/part of the population anywhere from 1%-99% of population | sample |
| finding the probability of a single event occurring # of favorable outcomes/# of total outcomes | probability of simple events |
| involve the probability of more than one event happening together # of favorable outcomes/# of total outcomes (multiply the probabilities together) | compound events |
| events that add together to equal a whole or one | complementary events |
| events that don't affect the outcome | independent events |
| events that affect the outcome | dependent events |
| probability using a logical approach to theorize how likely it is that a given situation will occur # of favorable outcomes/# of probable outcomes | theoretical probability |
| devises tests and experiments whose results are used to determine probability | experimental probability |
| express the likelihood of an event through the use of numbers between 0 & 1 | probability values |
