& Answers | 100% Correct | Grade A -
WGU
asymptote
A horizontal, vertical, or slanted line on a graph that a curve approaches but never
touches.
average rate of change
The average rate at which one variable is changing in relation to another variable's
changing.
big-box stores
A very large store, typically over 50,000 square feet, of plain design, resembling a large
box.
broadband
High-speed Internet access that is always on and much faster than dial-up.
calculate the average rate of change
The formula to compute an average rate of change is (y2-y1) divided by (x2-x1).
coefficient of determination
A statistic that measures how well a regression predictions approximate the real data
points. An r^2 of 1 indicates that the regression prediction is a perfect fit for the data.
common era
, A designation previously called "A.D.," meaning annus domini, "year of the Lord"; the
Common Era dates year 1 as the presumed year of Jesus of Nazareth's birth.
common ratio
The number by which each term in a sequence is multiplied to find the next number in
the sequence; for example 4 is the common ratio for the sequence [1, 4, 16, 64, 256...].
constant ratio
Occurs when the numeric relationship between two quantities - that is, how many times
one number contains the second - remains unchanged over time.
data
A collection of facts, which might be numbers, words, measurements, observations or
simply descriptions.
data regression
The process of examining data points to determine a valid equation. "Regression" refers
to bringing different data points down toward a normal average - "regressing" them.
dependent variable
A variable that is changed by another variable (called the independent variable); for
example, when a person is purchasing gas, the cost (the dependent variable) rises as
more gas is pumped into a car's tank (the independent variable).
equations
A mathematical statement that two things are equal; it consists of two expressions, one
on each side of an equals sign.
exponent
