WGU C784 EXAM QUESTIONS
WITH COMPLETE SOLUTION (A+
GRADED)
Rational number - ANSWER-A number that can be written as a ratio of
integers, which means it can be written as a fraction.
Product - ANSWER-The result of multiplying values.
Whole number - ANSWER-A number whose value is 0 or greater and can be
represented without a fractional or a decimal component.
Identity property - ANSWER-The property that 0 can be added to any number
without changing the value of the number. Likewise, 1 can be multiplied by
any number without changing the value of that number.
Associative property - ANSWER-The property that under certain operations in
a multi-step expression, the computations may be done in any order.
Commonly represented as (a + b) + c = a + (b + c). Addition and
multiplication both have this property, but subtraction and division do not.
Perfect square - ANSWER-The product of any integer with itself yields this.
So, a number is this if it can be written as the square of an integer. For
example, 9 is this because 3 * 3 = 9. Other examples are 16, 25, 36, 49,...
Set - ANSWER-In mathematics: a collection of numbers.
Order of operations - ANSWER-A set of rules that defines the order in which
mathematical operations should be performed
Multiplicative inverse - ANSWER-The number you must multiply x by to get 1.
For example, 5 and 1/5.
Principal square root - ANSWER-The positive square root of a number.
, Interval - ANSWER-A set of numbers between two specified values.
Operators - ANSWER-A word or symbol (such as + or -) that indicates an
operation between values.
Commutative - ANSWER-The property that the order of the numbers under
the operation does not change the result. Addition and multiplication have
this property: a + b = b + a and ab = ba.
Radical sign - ANSWER-The symbol which indicates to take the square root of
the number that follows.
Additive inverse - ANSWER-Two numbers equidistant from 0 on a number
line whose sum is 0. For example, 3 and -3.
Greatest common factor (GCF) - ANSWER-The greatest number that is both a
factor of a and a factor of b.
Factor tree - ANSWER-A graphical method used to identify the prime
factorization of an integer.
Integer - ANSWER-A number, (positive, negative, or zero), that can be
represented without a fractional or a decimal component.
Discrete - ANSWER-A collection of numbers whose values are distinct,
separate, and unconnected.
Prime factorization - ANSWER-Determining the set of prime numbers whose
product is the original integer.
Continuous - ANSWER-A collection of numbers whose values are not
dividable into distinct units.
Expressions - ANSWER-A string of terms that are connected by division,
addition, and subtraction operations.
Quotient - ANSWER-The result of a division expression.
Exponents - ANSWER-Sometimes called a power, it is a quantity that
represents repeated multiplication.
