WGU C784: A+ Graded End Term Exam –
Objective Assessment #1
What is the greatest common factor of 24 and 84 using prime factorization?
A. 2
B. 4
C. 8
D. 12 - ✔✔D. 12
Negative Number - ✔✔A number whose value is less than zero. On the number line, negative numbers
are to the left of zero.
Numerator - ✔✔The number that is written before the slash, or above the fraction bar, in a fraction.
Slope - ✔✔The number that describes the direction and steepness of a line drawn on the coordinate
plane. It is measured by 'rise over run'. Rise/Run = (the change in y value) / (the change in x value) = (y2-
y1)/(x2-x1).
Statistics - ✔✔The science that deals with the interpretation of numerical facts or data through theories
of probability. Also, the numerical facts or data themselves.
Conditional Percentages - ✔✔A way to approximate a percentage by dividing the number of times an
event occurred in an experiment by the total number of respondents in that row or column. See Relative
Frequency.
Hypothesis Test - ✔✔A statistical test that tells us whether a result is significant.
Disjoint - ✔✔Two events which both cannot occur at the same time.
What is 3/14 - 1/7?
, A. 1/14
B. 2/7
C. 5/14
D. 3/2 - ✔✔A. 1/14
Whole Number - ✔✔A number whose value is 0 or greater (negative number are not considered whole
numbers) and can be represented without a fractional or decimal component.
Cross Multiplying - ✔✔A method used to prove that a proportion is true.
Addition Principle of Equality - ✔✔The fact that we can add the same number to both sides of an
equation, and the result will be an equivalent equation.
Dot Plot - ✔✔A graphical representation of data that plots the frequency of data along a horizontal line.
Independent Variable - ✔✔The variable that may be the cause of some result, or is presented as the
variable that offers an explanation. Also called an explanatory variable.
Regression Equation - ✔✔An equation used to model the relationship between the response and
explanatory variables in a regression.
Tree Diagram - ✔✔A diagram that records all the events in a sample space by attaching each new set of
events to each branch of the earlier events. The number of outermost branches gives the sample size.
What is 2/3 + 1/4?
A. 11/12
B. 3/12
C. 3/7
D. 8/3 - ✔✔A. 11/12
