| Sample |
A
small group of elements used to represent a much larger group
of elements called the population. |
| Sample
Space |
The
list of all possible outcomes for an event. |
| Secant
(Sec) |
For
any acute angle in a right triangle, the ratio of the length
of the hypotenuse, to the length of the side adjacent. Sec x
= 1/cos x |
| Self-selected
Sample |
A
sample where information is volunteered by responding to a survey
or questionnaire. |
| Sine
(Sin) |
For
any acute angle in a right triangle, the ratio of the length
of the opposite side, to the length of the hypotenuse. |
| Slope |
Denoted
by the letter "m", the slope of a line represents
the change in the vertical coordinates (rise) over the change
in the horizontal coordinates (run) for any two points on a
given line. |
| Slope-Intercept
Form |
A
linear equation in the form: y = mx + b, where the coefficient
of "y" is positive 1. |
| Solve
the Triangle |
Determine
the measure of all unknown angles and sides of a given triangle. |
| Standard
Position |
An angle is said to be in standard position when its vertex
is located at the origin and its initial arm is resting on the
positive x-axis. |
| Standard
Form |
A
linear equation in the form: ax + by = c, where a, b, and c
are integers, and "a" is positive. |
| Stratified
Sample |
A
sample that is obtained by dividing the population into groups
so that each item in the population belongs to only one group. |
| Substitution |
A
method of solving systems of linear equations where you solve
for one variable in one equation and substitute this quantity
into the variable spot in the second equation. |
| Synthetic
Division |
A
method of dividing polynomial expressions using the coefficients
of the dividend and numerical divisor. |
| System
of Linear Equations |
A
set of two or more equations. The solution is the point of
intersection of lines representing the equations (if present). |
| Systematic
Sample |
A
sample that is drawn according to an arithmetic sequence. |
