The probabilities of each number are equal. Then statements A and C are correct.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Given

Pedro has a spinner with 4 sections numbered 1 through 4.

Pedro spins the spinner 100 times and records 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

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

B)  The theoretical probability that any one number is chosen is likely 0.20. This is incorrect because every number has an equal probability.

C)  It is likely that the spinner is fair. This statement is correct because the probabilities of each number are equal.

D)  The relative frequencies in the table are very different. This statement is incorrect. Because numbers 2 and 4 have the same frequency and the number 1 and 3 have slightly different frequencies.

More about the probability link is given below.

Complete the table of values for the equation y=x2-2x-1
lord [1]
  • y = x^2 - 2x - 1

1. If x = -2, then

y = (-2)^2 - 2(-2) - 1

= 4 + 4 - 1

= 7

2. If x = 0, then

y = (0)^2 - 2(0) - 1

= 0 - 0 - 1

= -1

3. If x = 2, then

y = (2)^2 - 2(2) - 1

= 4 - 4 - 1

= -1

4. If x = 3, then

y = (3)^2 - 2(3) - 1

= 9 - 6 - 1

= 2

Hope you could understand.

If you have any query, feel free to ask.

My head is HURTINGG and I cannot do this
tester [92]

Answer:

I think you didn't specify what order this decimals you want to be so:

  • If you want these to be in ascending order (lowest to highest), then:
  • 3.5, 4.37, 8.93, 10.4, 14.2 and 17.86.
  • If you want these to be in descending order (highest to lowest), then:
  • 17.86, 14.2, 10.4, 8.93, 4.37 and 3.5.

Hope this helps and if you could mark me as brainliest. Thanks!
