compound event
an event consisting of two or more events that can happen at the same time or one after
the other
constant of variation
the rate of change in a direct variation; also known as constant of proportionality
coordinate plane
a two-dimensional system in which a location is described by its distance from two
intersecting, perpendicular axes
counting principle
principle that states that the number of outcomes for a compound event is found by
multiplying the total number of outcomes for each event together
dependent events
compound events in which one event affects the likelihood of the other event
direct variation
a function of the form y = kx, where k is not zero
disjoint events
events that have no outcomes in common
domain
the independent or x values
experimental probability
a ratio representing the actual results of an experiment
favorable outcome
outcomes for a specific event
function
a relation in which there is only one output value for any given input value
independent events
compound events in which one event does not affect the likelihood of the other event
input
a value that is substituted in for the variable in a function and generates another value
(the output)
linear function
a function that forms a line when graphed
ordered pair
a group of two numbers written in the order (x, y), where the first value represents a
horizontal position and the second value represents a vertical position
origin
the intersection of the x-axis and y-axis
outcome
any possible results of an experiment
output
a value generated by a function from another value (an input) which was substituted into
the function and evaluated
probability
a measure of the likelihood of an event
