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 - (ANSWER)D. +/- 5
Composite Number - (ANSWER)A number with more factors that just one and itself.
Equivalent Fractions - (ANSWER)Different fractions that represent the same value.
X-Axis - (ANSWER)The horizontal line that passes through the origin on a coordinate plane.
Qualitative Data - (ANSWER)Non-numeric information based on some quality or characteristic.
No Correlation - (ANSWER)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 - (ANSWER)Using information from a data set to make predictions about data outside of the
original set.
Event - (ANSWER)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 - (ANSWER)D. 15
Operation - (ANSWER)In Mathematics, an operation is a procedure which generates a new value from
one or more operands, or Mathematical values.
Conditional Proportion - (ANSWER)A proportion where one part of the proportion is a variable, or
unknown quantity.
Coefficients - (ANSWER)A number by which a number is multiplied. This number is written in front of the
variable(s).
Mean - (ANSWER)Average, calculated by adding a series of elements in a data set together and dividing
by the total number in the series.
Outlier - (ANSWER)An observation point that is statistically distant from the other observations in the
dataset.
Regression Line - (ANSWER)The line of best fit to show the relationship between variables, the one that
minimizes distance from each data point to the line.
Experiment - (ANSWER)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
