Given the following
... [Show More] 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.
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.
Equivalent Fractions - ANS✔✔---Different fractions that represent the
same value.
Extrapolate - ANS✔✔---Using information from a data set to make
predictions about data outside of the original set.
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.
Event - ANS✔✔---An outcome, or set of outcomes, whose chance of
occurrence can be represented with a probability.
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.
.
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.
Experiment - ANS✔✔---A procedure that can be done repeatedly which
has a well defined set of outcomes
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 whic [Show Less]
