Older Adult Final Exam Practice Questions and Verified Answers
Given the following set of numbers: 3.3, -2.3, -16, 25. What D. +/- 5
are the square roots of the whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5
Composite Number A number with more factors that just one and itself.
Equivalent Fractions Different fractions that represent the same value.
X-Axis The horizontal line that passes through the origin on a coordinate plane.
Qualitative Data Non-numeric information based on some quality or characteristic.
No Correlation There is no apparent overall trend between the two variables. If the correlation
coefficient is 0, this only rules out a linear trend. There could be a non-linear or
curvilinear trend.
Extrapolate Using information from a data set to make predictions about data outside of the
original set.
Event An outcome, or set of outcomes, whose chance of occurrence can be represented
with a probability.
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. D. 15
What is the sum when adding together only the whole
numbers?
A. 5.5
B. 11
C. 12.5
D. 15
Operation In Mathematics, an operation is a procedure which generates a new value from one
or more operands, or Mathematical values.
Conditional Proportion A proportion where one part of the proportion is a variable, or unknown quantity.
Coefficients A number by which a number is multiplied. This number is written in front of the
variable(s).
Mean Average, calculated by adding a series of elements in a data set together and
dividing by the total number in the series.
Outlier An observation point that is statistically distant from the other observations in the
dataset.

Regression Line The line of best fit to show the relationship between variables, the one that
minimizes distance from each data point to the line.
Experiment A procedure that can be done repeatedly which has a well defined set of outcomes.
Given the following expression: 4 + 7 × (6 - 3)2. What is C. 67
the answer using proper order of operations?
A. 25
B. 46
C. 67
D. 99
Multi-Step Expression An expression or equation with more than two values and two or more operators
that requires multiple steps to be solved.
Improper Fraction A fraction where the number in the numerator is more than the number in the
denominator.
Y-Intercept The y-value of the point at which a line intersects with the y-axis.
Check Sheet A structured form or table that allows data to be collected by marking how often an
event has occurred in an certain interval.
Linear An expression or equation of degree 1.
Least Squares A technique for finding the regression line.
Sample Size The number of different outcomes for an experiment.
Given the following expression: 5 x (30 - 27)2 + 4. What is B. 49
the correct answer using the proper order of operations?
A. 34
B. 49
C. 65
D. 81
Exponents Sometimes called a power, it is a quantity that represents repeated multiplication.
Least Common Multiple (LCM) The smallest number in value that is a multiple of two or more numbers.
Order of Operations A set of rules that defines the order in which Mathematical operations should be
performed.
