  1. What is the probability of drawing a red card from a standard deck of 52 playing cards?

    Answer: 1/2

    A standard deck has 26 red cards (13 hearts + 13 diamonds) out of 52 total cards. Probability = 26/52 = 1/2.

  2. What is the value of log₁₀(1000)?

    Answer: 3

    log₁₀(1000) = 3 because 10³ = 1000.

  3. If the mean of five numbers is 12, what is their sum?

    Answer: 60

    Mean = Sum / Count, so Sum = Mean × Count = 12 × 5 = 60.

  4. What is the length of the hypotenuse of a right triangle with legs of 5 cm and 12 cm?

    Answer: 13 cm

    Using the Pythagorean theorem: c² = a² + b² = 25 + 144 = 169, so c = √169 = 13 cm.

  5. What is the equation of a circle with center (3, -2) and radius 5?

    Answer: (x - 3)² + (y + 2)² = 25

    The standard form of a circle is (x - h)² + (y - k)² = r², where (h,k) is the center and r is the radius: (x - 3)² + (y - (-2))² = 5² = (x - 3)² + (y + 2)² = 25.

  6. What is the domain of the function f(x) = √(x - 4)?

    Answer: x ≥ 4

    The expression under the square root must be non-negative: x - 4 ≥ 0, so x ≥ 4.
