  1. Which of the following is equivalent to 2(x − 5) + 3x?

    Answer: 5x − 10

    Distribute: 2(x − 5) = 2x − 10. Then add 3x: 2x − 10 + 3x = 5x − 10. Always distribute before combining like terms.

  2. A bag contains 4 red, 6 blue, and 2 green marbles. What is the probability of randomly picking a blue marble?

    Answer: 1/2

    Total marbles = 4 + 6 + 2 = 12. P(blue) = 6/12 = 1/2. Simplify by dividing numerator and denominator by 6.

  3. The price of a jacket was reduced from $80 to $60. What was the percent decrease?

    Answer: 25%

    Percent decrease = (change / original) × 100 = (20/80) × 100 = 25%. The decrease in price is $80 − $60 = $20.

  4. Solve the inequality: 2x − 3 > 7

    Answer: x > 5

    Add 3 to both sides: 2x > 10. Divide by 2: x > 5. When dividing by a positive number, the inequality direction stays the same.

  5. A data set has mean = 42 and median = 38. This indicates the distribution is:

    Answer: Skewed right (positively skewed)

    When the mean is greater than the median, the data is skewed right (positively skewed) because large outliers pull the mean upward.

  6. What is the slope of the line passing through (2, 3) and (6, 11)?

    Answer: 2

    Slope = (y₂ − y₁)/(x₂ − x₁) = (11 − 3)/(6 − 2) = 8/4 = 2. The slope represents the rate of change between two points.
