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.

A volleyball player sets the ball in the air, and the height of the ball after t seconds is given in feet by h= -16^2+12t+6. A t
pychu [463]

Answer:

Step-by-step explanation:

The given function is

h=-16t^2+12t+6

The graph of this function is a parabola that opens downwards

The line h(t)=8 intersects this parabola, when

t=0.5,t=0.25

The teammate can spike the ball after 0.25 seconds or 0.5 seconds.

The two solutions are reasonable. When the volleyball is accelerating into the air, it passes a height of 8 after 0.25 seconds.

When the ball is dropping after it attains maximum height, it attains another height of 8 after 0.5 seconds again.
