WILL MARK BRAINLEST! HELP ASAP Pedro has a spinner with 4 sections numbered 1 through 4. Pedro spins the spinner 100 times and r

ecords the results. He calculates the relative frequency of each outcome. Outcome 1 2 3 4 Relative Frequency 0.24 0.25 0.26 0.25 Which statements about Pedro's experiment are true? Select each correct answer.
A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment.

The theoretical probability that any one number is chosen is likely 0.20.

It is likely that the spinner is fair.

The relative frequencies in the table are very differenT.

Answer with explanation:

Relative frequency of a Spinner having 4 sections ,numbered through 1 through 4

Outcome                   1            2         3         4

Relative Frequency 0.24    0.25   0.26     0.25

As,the Spinner is Spined 100,times ,so there is little difference in relative frequency of outcome 1 and Outcome 4.

If the Spinner has been ,Spined more than 100 times , may be more than 150 times, the Relative frequency of each outcome would have been equal to 0.25.

Probability of getting either of section on the spinner ,that is from 1 to 4

              =\frac{1}{4}=0.25

The correct statement are

1. A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment.

2.The theoretical probability that any one number is chosen is likely 0.20.

   ⇒⇒Incorrect,should be 0.25.

3.As,the relative frequency are closer to ,0.25 when spinner got Spined 100 times.

It is likely that the spinner is fair.

4. Relative frequency of each outcome should be 0.25, and the all the numbers in the table which are relative frequency are approximately equal to 0.25.

The relative frequencies in the table are very different.⇒⇒Incorrect Statement

⇒⇒⇒⇒⇒Option 1 and Option 3, are correct statement.

7. In a state lottery, a player must choose 8 of the numbers from 1 to 40. The lottery commission then performs an experiment th
Vlad1618 [11]

Answer:a) P(8 of the players numbers are drawn)=1.3×10^-8

b) P(7 of the players number are drrawn)=3.33×10^-c) P(at least 6 of the players number were drawn)=1.84×10^-4

Step-by-step explanation:

Players has 8 combinations of numbers from 1-40. The outcome S contains all the combinations of 8 out of 40

a) P(8 of the players numbers are drawn)= 1/40/8= 1.3×10^-8

There are one in hundred million chances that the draw numbers are precisely the chosen ones.

b) Number of ways of drawing 78 selected numbers from 1-40=8×(40-7)

8×32

P(7 of the players number are drawn)=8×32/40 =3.33×10^-6.

There are approximately 300,000 chances that 7 of the players numbers are chosen

c) P(at least 6 players numbers are drawn)= 32/2×(8/6) ways to draw.

P(at least 6 players numbers are drawn)=P(all 8 chosen are drawn)+P(7 players numbers drawn)+P(6 chosen are drawn) = 1+ 8 x32/40/8 +[8\6 ×32/2]

P(at least 6 players numbers are drawn) = 1.84×10^-4.

There are approximately 5400chances that at least6 of the numbers drawn are chosen by the player.

Given m∠JML = 80 and m∠KML = 33, what is m∠JMK
Harrizon [31]

Answer:

<h2>47°</h2>

Step-by-step explanation:

Given m∠JML = 80 and m∠KML = 33, to calculate the value of angle m∠JMK, we will apply the formula since all the angles are all acting at point M.

m∠JML = m∠JMK+m∠KML

Substituting the values given into the equation;

80 = m∠JMK + 33

subtract 33 from both sides of the equation

m∠JMK = 80-33

m∠JMK = 47°

<em>Hence the value of angle m∠JMK is 47°</em>

luke jogged a total of 56.5 miles last week. if luke jogged the same distance,d, each day for 3 days and half that distance on e
Leokris [45]
The algebraic equation used to answer this question is:
3d + 4(1/2d) = 56.5
This is because he ran d, the distance, three times that week. For the rest of the four days, he ran 1/2 the distance, or half d.
To find the answer, you first distribute:
3d + 2d = 56.5
Add like terms:
5d = 56.5
Divide both side by 5:
5d/5 = 56.5/5
d = 11.3
On the first three days, Luke jogged 11.3 miles. On the remaining days, where he jogged 1/2d, Luke jogged 5.65 miles.
Hope this helps!

Can someone help me?
Readme [11.4K]

Answer:

B

Step-by-step explanation:

The answer is B because if you move two times to the right it gives you 0.09 like the eqution.

But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.

Just reminder: B and D have the same result!! just different coefficient

True or false 798.7 divided by 1,000= 7.987
aleksandrvk [35]

False. 798.7 divided by 1000 is 0.7987 because 1000 has three zeros, so you move the decimal point three units/numbers to the left

False. 73.09 divided by 100 is 0.7309, you are not multiplying by 100

False. 75.04 divided by 10 is 7.504, you are not multiplying by 10
