complete questions and answers
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 -ANSD. +/- 5
Composite Number -ANSA number with more factors that just one and itself.
Equivalent Fractions -ANSDifferent fractions that represent the same value.
X-Axis -ANSThe horizontal line that passes through the origin on a coordinate plane.
Qualitative Data -ANSNon-numeric information based on some quality or characteristic.
No Correlation -ANSThere 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 -ANSUsing information from a data set to make predictions about data
outside of the original set.
Event -ANSAn 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 -ANSD. 15
Operation -ANSIn Mathematics, an operation is a procedure which generates a new
value from one or more operands, or Mathematical values.
, Conditional Proportion -ANSA proportion where one part of the proportion is a variable,
or unknown quantity.
Coefficients -ANSA number by which a number is multiplied. This number is written in
front of the variable(s).
Mean -ANSAverage, calculated by adding a series of elements in a data set together
and dividing by the total number in the series.
Outlier -ANSAn observation point that is statistically distant from the other observations
in the dataset.
Regression Line -ANSThe line of best fit to show the relationship between variables, the
one that minimizes distance from each data point to the line.
Experiment -ANSA 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 -ANSC. 67
Multi-Step Expression -ANSAn expression or equation with more than two values and
two or more operators that requires multiple steps to be solved.
Improper Fraction -ANSA fraction where the number in the numerator is more than the
number in the denominator.
Y-Intercept -ANSThe y-value of the point at which a line intersects with the y-axis.
Check Sheet -ANSA structured form or table that allows data to be collected by marking
how often an event has occurred in an certain interval.
Linear -ANSAn expression or equation of degree 1.
Least Squares -ANSA technique for finding the regression line.
Sample Size -ANSThe 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
