An association between the points in a plane and ordered pairs of real numbers; or an association between the points in three-dimensional space and ordered triples of real numbers

• Binomial

A polynomial with exactly two terms

• Correlation coefficient

A measure of the strength of the linear relationship between two variables, pp. 146, 162.

• Deductive reasoning

The process of utilizing general information to prove a specific hypothesis

• Exponent

The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.

The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).
