  1. If 4 workers can build a wall in 6 days, how many days would 3 workers take at the same rate?

    Answer: 8 days

    Total work is 24 worker-days, so 3 workers take 24 / 3 = 8 days.

  2. What is the slope of the line passing through (1, 2) and (4, 11)?

    Answer: 3

    Slope = (11 - 2)/(4 - 1) = 9/3 = 3.

  3. Simplify: (2x^3)(3x^4).

    Answer: 6x^7

    Multiply coefficients (6) and add exponents (3+4=7) to get 6x^7.

  4. A bag has 3 red, 4 blue, and 5 green marbles. What is the probability of drawing a blue marble?

    Answer: 1/3

    There are 12 marbles and 4 blue, so probability is 4/12 = 1/3.

  5. Solve for x: 2(x + 3) = 4x - 2.

    Answer: 4

    2x + 6 = 4x - 2 gives 8 = 2x, so x = 4.

  6. The price of a stock rose from $50 to $65. What was the percent increase?

    Answer: 30%

    Increase is $15; 15/50 = 0.30, or 30%.

  7. What is the median of the data set 4, 8, 15, 16, 23, 42?

    Answer: 15.5

    With six values, the median is the average of the two middle numbers: (15 + 16)/2 = 15.5.
