Sample NES Mathematics (304) Practice Questions

Try these sample questions to review concepts for the NES Mathematics (304) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A class has 250 students. If 18% of the students are absent on a field-trip day, how many students are absent?
A.45
B.18
C.36
D.50
Explanation: Convert 18% to 0.18 and multiply by 250: 0.18(250) = 45. So 45 students are absent.
2A recipe uses 3 cups of flour for every 2 cups of oats. If 8 cups of oats are used, how many cups of flour are needed?
A.12
B.8
C.10
D.16
Explanation: The oat amount is multiplied by 4, from 2 cups to 8 cups. Multiply the flour amount by the same factor: 3 x 4 = 12 cups.
3Which number is the greatest common factor of 84 and 126?
A.42
B.21
C.14
D.84
Explanation: Prime factorization gives 84 = 2^2 x 3 x 7 and 126 = 2 x 3^2 x 7. The common factors with the least exponents are 2 x 3 x 7 = 42.
4Which set is not closed under subtraction?
A.Whole numbers
B.Integers
C.Rational numbers
D.Real numbers
Explanation: Whole numbers are not closed under subtraction because 3 - 5 = -2, and -2 is not a whole number.
5Which expression represents the statement: five less than twice a number n?
A.2n - 5
B.5 - 2n
C.2(n - 5)
D.5n - 2
Explanation: Twice the number is 2n. Five less than that quantity is 2n - 5.
6A cyclist's distance changes from 20 miles to 50 miles over 6 hours. What is the average rate of change?
A.5 miles per hour
B.6 miles per hour
C.8 miles per hour
D.12 miles per hour
Explanation: Average rate of change is change in distance divided by change in time: (50 - 20) / 6 = 30 / 6 = 5 miles per hour.
7A store sells notebooks for $1.95 each. Which estimate is most reasonable for the cost of 48 notebooks before tax?
A.About $96
B.About $50
C.About $120
D.About $150
Explanation: Round $1.95 to about $2 and 48 to about 50. Then 2 x 48 is about 96, or 2 x 50 is about 100, so $96 is the most reasonable estimate.
8Which statement is the contrapositive of: If a quadrilateral is a square, then it has four congruent sides?
A.If a quadrilateral does not have four congruent sides, then it is not a square.
B.If a quadrilateral has four congruent sides, then it is a square.
C.If a quadrilateral is not a square, then it does not have four congruent sides.
D.If a quadrilateral has four congruent sides, then it is not a square.
Explanation: The contrapositive of if p then q is if not q then not p. Here p is being a square and q is having four congruent sides.
9For which truth values of p and q is the conditional statement p -> q false?
A.p is true and q is false
B.p is true and q is true
C.p is false and q is true
D.p is false and q is false
Explanation: A conditional p -> q is false only when the hypothesis p is true and the conclusion q is false.
10What is (3 + 2i)(1 - 4i) in standard form?
A.11 - 10i
B.-5 - 10i
C.11 + 10i
D.-5 + 14i
Explanation: Multiply: 3(1) + 3(-4i) + 2i(1) + 2i(-4i) = 3 - 12i + 2i - 8i^2. Since i^2 = -1, this is 3 - 10i + 8 = 11 - 10i.

NES Mathematics (304): Suggested Study Strategy

1Treat algebra and functions as the largest domain: work mixed problems on function notation, transformations, inverses, systems, rational expressions, logarithms, and quadratic modeling.
2Practice mathematical reasoning explicitly: identify assumptions, justify steps, use counterexamples, and translate among verbal, symbolic, tabular, and graphical representations.
3For geometry, pair formulas with reasoning: know why scale factors square for area, how coordinate proof supports classification, and which congruence or parallel-line theorem applies.
4For trigonometry and calculus, keep a fast reference sheet of unit-circle values, identities, derivative rules, integral rules, and common interpretations of rates and accumulation.
5For probability and statistics, distinguish similar concepts: conditional probability vs joint probability, mean vs median, standard deviation vs IQR, and sample bias vs random variation.
6Use calculator-aware practice: let the provided scientific calculator handle arithmetic, but reserve study time for setup, domain restrictions, sign analysis, and reasonableness checks.
