A+
◉ 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.
