Formulas (1/2)
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
B. 46
C. 67
D. 99 - (ANSWER)C. 67
Multi-Step Expression - (ANSWER)An expression or equation with more than two
values and two or more operators that requires multiple steps to be solved.
Improper Fraction - (ANSWER)A fraction where the number in the numerator is
more than the number in the denominator.
