Addition principle of probability.
P(A or B) = P(A) + P(B)  P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

Combination
An arrangement of elements of a set, in which order is not important

Constant term
See Polynomial function

Division
a b = aa 1 b b, b Z 0

Endpoint of an interval
A real number that represents one “end” of an interval.

Equal complex numbers
Complex numbers whose real parts are equal and whose imaginary parts are equal.

Frequency distribution
See Frequency table.

Leaf
The final digit of a number in a stemplot.

Line graph
A graph of data in which consecutive data points are connected by line segments

Major axis
The line segment through the foci of an ellipse with endpoints on the ellipse

Measure of spread
A measure that tells how widely distributed data are.

Number line graph of a linear inequality
The graph of the solutions of a linear inequality (in x) on a number line

Outcomes
The various possible results of an experiment.

Paraboloid of revolution
A surface generated by rotating a parabola about its line of symmetry.

Power rule of logarithms
logb Rc = c logb R, R 7 0.

Pseudorandom numbers
Computergenerated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

Quartile
The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

Range (in statistics)
The difference between the greatest and least values in a data set.

Speed
The magnitude of the velocity vector, given by distance/time.

Vector
An ordered pair <a, b> of real numbers in the plane, or an ordered triple <a, b, c> of real numbers in space. A vector has both magnitude and direction.
