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)

Bias
A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

Chord of a conic
A line segment with endpoints on the conic

Combinatorics
A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

Dot product
The number found when the corresponding components of two vectors are multiplied and then summed

Explanatory variable
A variable that affects a response variable.

Fitting a line or curve to data
Finding a line or curve that comes close to passing through all the points in a scatter plot.

Implied domain
The domain of a function’s algebraic expression.

Lower bound test for real zeros
A test for finding a lower bound for the real zeros of a polynomial

Multiplicative inverse of a real number
The reciprocal of b, or 1/b, b Z 0

Polynomial function
A function in which ƒ(x)is a polynomial in x, p. 158.

Position vector of the point (a, b)
The vector <a,b>.

Reference angle
See Reference triangle

Semiperimeter of a triangle
Onehalf of the sum of the lengths of the sides of a triangle.

Solve by elimination or substitution
Methods for solving systems of linear equations.

Standard representation of a vector
A representative arrow with its initial point at the origin

Symmetric about the origin
A graph in which (x, y) is on the the graph whenever (x, y) is; or a graph in which (r, ?) or (r, ? + ?) is on the graph whenever (r, ?) is

Triangular form
A special form for a system of linear equations that facilitates finding the solution.
