Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?

Answer: ✔ He did not perform enough trials to compare the theoretical and experimental probabilities.

Mali performed an experiment with a standard deck of 52 cards. She wanted to see if the face cards (Ace, King, Queen, and Jack) came up the expected number of times when she randomly selected 13 cards from the deck.

Mali noticed that the observed frequencies did not match the predicted frequencies. What does she need to change in her experiment to get closer to the predicted values based on the theoretical probability for all the face cards?

Answer: ✔ increase the number of trails

Emma conducted an experiment in which she rolled a six-sided, fair number cube 300 times. How many times would you predict she rolled a 6?

Answer: ✔ Emma conducted an experiment and she rolled a six sided number cube 300 times. The theoretical will be rolling a 6 and it can also be 1/6. 6 would be rolled about (1/6)(300), or it could be 50, times.

A number cube is rolled 60 times. The results of those 60 trials are recorded in the table. Complete the table

Answer: ✔ 1/5 ✔ 2/15

Which statements are true? Check all that apply.

Answer: ✔ As the number of trials increases, experimental probability is closer to theoretical probability.

✔ As the number of trials increases, there is no change in the theoretical probabilities.

John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even number. He makes a prediction of 20 times. Is it a good prediction? What would your prediction be based on theoretical probability?

Answer: ✔ If John rolled a six- sided number and he predicts that it would be 20 times, and my predict would be 3 cause i divided 60 and 20 which gave me 3. And John prediction was to low and the theoretical probability of 1/2, and (1/2)(60) is 30. and also a number cube has 3 even number.

Maya wants to perform an experiment with a spinner labeled A, B, and C. The theoretical probabilities for each section are: P(A) = ½, P(B) = ¼, and P(C) = ¼. Which spinner could she use?

If A PQR = ASTU, which statement must be true?

Aleks [24]

**Answer:**

O A. PQ = SU

**Step-by-step explanation:**

When two triangles are congruent then by CPCTC,

their corresponding parts ( angles and sides ) must be congruent.

In triangles PQR and STU,

Side PQ, QR and RP are corresponding to the sides ST, TU and US respectively,

Also, angles P, Q and R are corresponding to angles S, T and U respectively.

Here, Δ PQR ≅ Δ STU,

Thus, by the above property,

PQ ≅ ST, QR ≅ TU and RP ≅ US,

∠P ≅ ∠T, ∠Q ≅ ∠T and ∠R ≅ ∠U

Solve the slope for the table.

Nikitich [7]

**Answer:**

The slope is 0

**Step-by-step explanation:**

All y-values are equal to 5 meaning the graph is a straight horizontal line. Slope is the rate at which a graph increases or decreases. Seeing as this graph doesn't do so, the slope is 0.

**Answer:**

## 50

**Step-by-step explanation:**

A number cube has six sides.

The probability of landing on any of the numbers is equal. The theoretical probability of rolling a 6 is 1/6. I expect a 6 to be rolled (1/6)(300), or **50** of 300 times.
