  • Question 5 (request help)

    Multiple Representations A spinner with three equal-sized sections marked A, B, and C is spun 100 times.

    a. Numbers What is the theoretical probability of landing on A?
  • Question 5 (request help)

    b. Numbers The results of the experiment are shown in the table. What is the experimental probability of landing on A? on C?

  • Question 6 (request help)

    Persevere with Problems The experimental probability of a coin landing on heads is \(\frac{7}{12}\) . If the coin landed on tails 30 times, find the number of tosses.

  • Question 7 (request help)

    Reason Inductively Twenty sharpened pencils are placed in a box containing an unknown number of unsharpened pencils. Suppose 15 pencils are removed at random and five of the removed pencils are sharpened. Based on this, is it reasonable to assume that the number of unsharpened pencils was 40? Explain your reasoning.

  • Question 8 (request help)

    The results of spinning a spinner with six equal sections  are shown. Determine the minimum number of additional spins needed and their frequency of landing on each color so that the experimental probabilities will be equal with the theoretical probabilities.

    Explain your reasoning.

  • Question 9 (request help)

    When playing a board game, Marisol rolled a number cube 10 times. She rolled an even number 7 times. Based on her results, what is the experimental probability Marisa will roll an odd number on her next roll?
    • \(\large\frac{1}{6}\)
    • \(\large\frac{3}{10}\)
    • \(\large\frac{7}{10}\)
    • \(\large\frac{5}{6}\)
