Update ) Quantitative Literacy
| Questions & Answers | 100% Correct |
Grade A – WGU
Question 1: What is a unit in the context of quantitative literacy?
Answer: A value related to a specific quantity
Rationale: A unit relates a numerical value to a specific measurement, such as inches for length
or liters for volume.
Question 2: What is the bottom of a fraction called?
Answer: Denominator
Rationale: The denominator represents the number of equal parts in a whole, located below the
fraction line.
Question 3: What is a relation of each value of one variable to a value of another variable?
Answer: Function
Rationale: A function maps each input value to exactly one output value, defining a relationship
between variables.
Question 4: What is the process of earning interest on both the principal and previously earned
interest?
Answer: Compounding
Rationale: Compounding involves earning interest on the initial amount (principal) and
accumulated interest.
Question 5: What is the formula for the volume of a cylinder?
Answer: V = πr²h
Rationale: The volume of a cylinder is calculated as π times the radius squared times the height.
, Question 6: What must be consistent when adding units in an equation?
Answer: Units must be the same
Rationale: Units must be converted to the same type (e.g., inches to feet) for addition or
subtraction.
Question 7: What is the slope-intercept form of a linear equation?
Answer: y = mx + b
Rationale: In this form, m is the slope, and b is the y-intercept of the line.
Question 8: What is the formula for the area of a rectangle?
Answer: A = l × w
Rationale: The area of a rectangle is calculated by multiplying its length by its width.
Question 9: What is the probability of rolling a 3 on a six-sided die?
Answer: 1/6
Rationale: There is one favorable outcome (3) out of six possible outcomes, so P = 1/6.
Question 10: What does a negative slope indicate on a graph?
Answer: Decreasing relationship
Rationale: A negative slope shows that as the x-value increases, the y-value decreases.
Question 11: How many significant figures are in the number 0.00720?
Answer: 3
Rationale: Leading zeros are not significant; the digits 7, 2, and 0 after the decimal are
significant.
Question 12: What is the formula for simple interest?
Answer: I = PRT
Rationale: Simple interest is calculated as principal (P) times rate (R) times time (T).
