Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots of the
whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5 - ANS✔✔-D. +/- 5
Composite Number - ANS✔✔-A number with more factors that just one and itself.
Equivalent Fractions - ANS✔✔-Different fractions that represent the same value.
X-Axis - ANS✔✔-The horizontal line that passes through the origin on a coordinate
plane.
Qualitative Data - ANS✔✔-Non-numeric information based on some quality or
characteristic.
No Correlation - ANS✔✔-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 - ANS✔✔-Using information from a data set to make predictions about data
outside of the original set.
Event - ANS✔✔-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. What is the sum when adding
together only the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15 - ANS✔✔-D. 15
Operation - ANS✔✔-In Mathematics, an operation is a procedure which generates a
new value from one or more operands, or Mathematical values.
Conditional Proportion - ANS✔✔-A proportion where one part of the proportion is a
variable, or unknown quantity.
Coefficients - ANS✔✔-A number by which a number is multiplied. This number is written
in front of the variable(s).
Mean - ANS✔✔-Average, calculated by adding a series of elements in a data set
together and dividing by the total number in the series.
Outlier - ANS✔✔-An observation point that is statistically distant from the other
observations in the dataset.
Regression Line - ANS✔✔-The line of best fit to show the relationship between
variables, the one that minimizes distance from each data point to the line.
Experiment - ANS✔✔-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 the answer using proper order
of operations?
A. 25
B. 46
C. 67
D. 99 - ANS✔✔-C. 67
Multi-Step Expression - ANS✔✔-An expression or equation with more than two values
and two or more operators that requires multiple steps to be solved.
Improper Fraction - ANS✔✔-A fraction where the number in the numerator is more than
the number in the denominator.
Y-Intercept - ANS✔✔-The y-value of the point at which a line intersects with the y-axis.
Check Sheet - ANS✔✔-A structured form or table that allows data to be collected by
marking how often an event has occurred in an certain interval.
Linear - ANS✔✔-An expression or equation of degree 1.
Least Squares - ANS✔✔-A technique for finding the regression line.
Sample Size - ANS✔✔-The number of different outcomes for an experiment.
Given the following expression: 5 x (30 - 27)2 + 4. What is the correct answer using the
proper order of operations?
A. 34
B. 49
C. 65
D. 81 - ANS✔✔-B. 49
Exponents - ANS✔✔-Sometimes called a power, it is a quantity that represents
repeated multiplication.
Least Common Multiple (LCM) - ANS✔✔-The smallest number in value that is a
multiple of two or more numbers.
Order of Operations - ANS✔✔-A set of rules that defines the order in which
Mathematical operations should be performed.
Numerical Summary - ANS✔✔-A number used to describe a specific characteristic
about a data set.
Joint Frequencies - ANS✔✔-The frequency counts in each cell of the table.
Linear Extrapolation - ANS✔✔-Estimation using the linear regression equation is made
outside known data points.
Fair - ANS✔✔-An experiment in which all outcomes are equally likely.
What is the greatest common factor of 132 and the square root of 121 using prime
factorization?
A. 1
B. 2
