,Question 1
Q: What is the correct order of operations for evaluating mathematical expressions?
A) Parentheses, exponents, addition, subtraction, multiplication, division
B) Exponents, parentheses, multiplication, division, addition, subtraction
C) Parentheses, exponents, multiplication and division, addition and subtraction
D) Multiplication, division, exponents, parentheses, addition, subtraction
Correct Answer: C
Rationale: The standard order is PEMDAS (Please Excuse My Dear Aunt Sally):
Parentheses first, then Exponents, then Multiplication and Division (left to right), finally
Addition and Subtraction (left to right).
Question 2
Q: Which type of store is typically over 50,000 square feet and resembles a large box in
design?
A) Specialty Stores
B) Big Box Stores
C) Convenience Stores
D) Discount Stores
Correct Answer: B
Rationale: "Big box stores" is the retail industry term for large, plain, warehouse-like
stores (e.g., Walmart, Home Depot).
, Question 3
Q: What is the act of estimation by projecting known information beyond the range of
available data?
A) Linearization
B) Regression
C) Interpolation
D) Extrapolation
Correct Answer: D
Rationale: Extrapolation uses known data points to predict values outside the original
data range. Interpolation predicts within the range.
Question 4
Q: What is the notation called that names a function defined by an equation (e.g.,
f (x) = 3x + 2)?
A) Interval notation
B) Inequality notation
C) Function notation
D) Ordered pair notation
Correct Answer: C
Rationale: Function notation (e.g., f (x)) explicitly names the function and shows input-
output relationship.
Question 5
Q: What is the representation of an input and output as (x, y)?
A) Input-output pair
B) Output variable
C) Ordered pair
D) Coordinate notation
