are two events that exist such that one event will occur if and only if the other does not take place

is the average of a set of given numbers. Add up all of the numbers and divide by the number of numbers in the data set

an equation between two variables that gives a straight line when plotted on a graph, which is represented by y = mx + b

all positive and negative whole numbers

the chance of an event occurring

the entire group of items or individuals being studied

a variable quantity having a constant ratio to another quantity

the part of a fraction that is below the line and that functions as the divisor of the numerator
