  1. A data set contains the values 4, 7, 7, 9, 13. What is the median?

    Answer: 7

    When the values are ordered (4, 7, 7, 9, 13), the middle value (median) is 7.

  2. A bag contains 3 red, 5 blue, and 2 green marbles. What is the probability of randomly picking a blue marble?

    Answer: 5/10

    Probability = favorable outcomes ÷ total outcomes = 5 ÷ 10 = 5/10 = 1/2.

  3. What is the mean of the numbers 8, 12, 15, 9, 16?

    Answer: 12

    Mean = sum ÷ count = (8 + 12 + 15 + 9 + 16) ÷ 5 = 60 ÷ 5 = 12.

  4. A number pattern begins: 2, 6, 18, 54, ... What is the next number?

    Answer: 162

    Each term is multiplied by 3: 54 × 3 = 162.

  5. If f(x) = 2x² − 3, what is f(4)?

    Answer: 29

    f(4) = 2(4²) − 3 = 2(16) − 3 = 32 − 3 = 29.

  6. A store offers a 20% discount on an item originally priced at $85. What is the sale price?

    Answer: $68

    Discount = 20% × $85 = $17; Sale price = $85 − $17 = $68.
