Given the equation: (.5475 - .3025) x .15. What is the solution rounded to the nearest
thousandth?
A. .03675
B. .0368
C. .368
D. .037 - ANS✔✔-D. .037
Rational Number - ANS✔✔-A rational number is a number that can be written as a ratio
of integers, which means it can be written as a fraction.
Percent Sign - ANS✔✔-A symbol used to denote percentages.
Horizontal Line - ANS✔✔-A line that runs left to right on the coordinate plane, parallel to
the x-axis. It has no 'rise' or change in y-value.
Interquartile Range - ANS✔✔-The difference, in value, between the bottom and top 25
percent of the sample or population.
Box Plot - ANS✔✔-A graphical rendering of the range and the first and third quartiles of
a data set with the data set's median in the center.
Control Group - ANS✔✔-In an experimental study, this group does not receive
treatment or receives a placebo.
Venn Diagram - ANS✔✔-A type of chart that illustrates distinct sets, topics, or objects
relate to one another. Uses circles to represent events.
, 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.
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.
Experiment - ANS✔✔-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 - 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.
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.
