WGU C955 CERTIFICATION EVALUATION
2026 EXAM QUESTIONS AND SOLUTIONS
Answer: The number an exponent is written next to
◉ Variable.
Answer: Symbol that represents our holds the place of a numerical
value
◉ Coefficient.
Answer: A number by which a variable is being multiplied.
Coefficients are written in front of variables. 16x, 16 is coefficient. If
there is no number you assume an invisible1.
◉ Term.
Answer: Can be a single constant, a single, or a number of constants
and variables multiplied together.
◉ Algebraic expression.
Answer: String of terms connected by division, addition, and
subtraction.
,◉ How to write an algebraic expression.
Answer: Constants at end. Write terms with the largest exponents
first. Always write in descending order of exponent value with
constants at the end.
◉ Inverse operation.
Answer: Operations that undo each other. Subtraction is inverse of
addition. Division is inverse of multiplication.
◉ Like terms.
Answer: Have the same variable with the same exponent
◉ Degree of an expression.
Answer: Refers to largest exponent in an expression
◉ Linear.
Answer: Has degree of 1
◉ Quadratic.
Answer: Has degree of 2
◉ Cubic.
, Answer: Has degree of 3
◉ Constant.
Answer: Has degree of 0
◉ Distributive property.
Answer: Principle used to multiply a single term by multiple terms.
If there are parenthesis around multiple terms which are in turn
multiplied by a single term, we can use this property.
◉ Histogram.
Answer: A graphical representation -- bars, measuring the frequency
within each interval
◉ Skewed right.
Answer: Not a symmetric distribution, the tail is on the right
◉ Measures of center.
Answer: Median, the mean (and mode)
◉ Measures of spread.
Answer: Range, IQR & standard deviation
