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 |
