WGU C955 OBJECTIVE ASSESSMENT
APPLIED PROBABILITY AND
STATISTICS OA EXAM Questions and
Answers Graded A+
Discrete data - Correct answer-Has distinct values, can be counted, had
unconnected points (think dots)
Continuous data - Correct answer-Has values within a range, measured not
counted, does not have gaps between data points (data is connected lines or
curves).
Example of discrete data - Correct answer-Days of the week
Expressions - Correct answer-A group of symbols such as numbers and operators
that has mathematical validity
Commutative - Correct answer-The order in which the numbers appear in the sum
can be reversed

,Identity property - Correct answer-Adding 0 to any number does not change the
original number
Additive inverse - Correct answer-Values that are equally far from 0 on the number
line.
Negative - Correct answer-When multiplying a positive number by a negative
number the result is always
Positive - Correct answer-Multiplying a negative number by a negative number
results in a positive
Factors - Correct answer-Integers that evenly divide the initial integer
Prime number - Correct answer-Positive integer with exactly two positive factors
consisting of 1 and itself
Composite number - Correct answer-Has at least one positive factor other than one
and itself
Factorization - Correct answer-Process of breaking up a composite number into its
prime factors
fundamental theorem of arithmetic - Correct answer-Any integer greater than one
is either Prime or the product of Prime numbers
Principal square root - Correct answer-Positive square root of a number

, Radican - Correct answer-Number under radical sign √16=4
Open Circle - Correct answer-Represents less than or greatest than on the number
line
Perfect square - Correct answer-Product of any integer with itself yields a perfect
square.
Whole numbers - Correct answer-positive numbers with a whole value
Integers - Correct answer-Numbers with no fractions or decimal value but can be
positive or negative
Rational numbers - Correct answer-Numbers that can be expressed as a fraction or
decimal values that have that end or repeat forever. Includes all integers since all
integers can be expressed as fractions.
Real numbers - Correct answer-Everything that can be included in a number line
including pi.
Fractions - Correct answer-Express numbers which are part of a whole
Numerator - Correct answer-Number written before the slash or above the fraction
bar
Proper fraction - Correct answer-Numerator is less than denominator and the value
of the fraction is less than one
