  1. A store marks up items by 40%. If the cost price of an item is $50, what is the selling price?

    Answer: $70

    Markup = 40% × $50 = $20; selling price = $50 + $20 = $70.

  2. What is the value of (−3)³?

    Answer: −27

    (−3)³ = (−3)(−3)(−3) = (9)(−3) = −27.

  3. Two parallel lines are cut by a transversal. One angle measures 65°. What is the measure of its co-interior (same-side interior) angle?

    Answer: 115°

    Co-interior angles are supplementary, so the other angle = 180° − 65° = 115°.

  4. If the graph of a parabola has x-intercepts at x = 1 and x = 5, what is the x-coordinate of its vertex?

    Answer: 3

    The vertex lies on the axis of symmetry, halfway between the x-intercepts: (1 + 5)/2 = 3.

  5. In a data set, the mean is 12 and the median is 15. This suggests the distribution is:

    Answer: Skewed left (negatively skewed)

    When mean < median, the distribution is pulled toward lower values, indicating a left (negative) skew.

  6. What is the greatest common factor of 36 and 48?

    Answer: 12

    36 = 2² × 3² and 48 = 2⁴ × 3; GCF = 2² × 3 = 12.

  7. A function is defined as f(x) = 4 − x². For which values of x is f(x) > 0?

    Answer: −2 < x < 2

    4 − x² > 0 when x² < 4, which gives −2 < x < 2.
