C957 APPLIED ALGEBRA -
MODULE 1 EXAM QUESTIONS

CORRECT ANSWERS GRADE A+

Asymptote - answer-a horizontal, vertical, or slanted line that a graph approaches but
never touches
coefficient of determination - answer-A statistic that measures how well a regression
prediction approximates the real data points. An r^2 of 1 indicates that the regression
prediction is a perfect fit for the data
common ratio - answer-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 - answer-Occurs when the numeric relationship between two quantities-
that is, how many times one number contains the second- remains unchanged over
time
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
equation - answer-A mathematical sentence that contains an equals sign.
explanatory variable - answer-A variable that, as it changes, affects another variable
(called the response variable); for example, as a person pumps more gas into a car's
tank(the explanatory variable), the cost of the purchase rises (the response variable)
