PERCENT CORRECT
◉ constant ratio.
Answer: Occurs when the numeric relationship between two
quantities - that is, how many times one number contains the second
- remains unchanged over time.
◉ data.
Answer: A collection of facts, which might be numbers, words,
measurements, observations or simply descriptions.
◉ data regression.
Answer: 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.
Answer: 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.
Answer: A mathematical statement that two things are equal; it
consists of two expressions, one on each side of an equals sign.
◉ exponent.
Answer: A mathematical notation - a superscript - that defines the
number of times a number is multiplied by itself.
◉ exponential function.
Answer: A function that has an extremely rapid increase or decrease
in quantity in proportion to its current value; its form is f(x) = b^2.
◉ extrapolation.
Answer: A method of inserting new data points outside the range of
a known set of data points. ("Extra" means outside.)
◉ f(x) = mx.
Answer: A very basic function; it means that the function of x is the
product of a constant multiplied by a variable input, x.
