This passage is about the domain of a function. The domain of a function is the set of all points that you can give to the function as an input.
Points not belonging to the domain are not good inputs for the function. In this example, 3 is not a good input, because if you try to evaluate the function at
, i.e. if you plug 3 in place of x, you get
![f(3) = \dfrac{5}{3-3} = \dfrac{5}{0}](https://tex.z-dn.net/?f=%20f%283%29%20%3D%20%5Cdfrac%7B5%7D%7B3-3%7D%20%3D%20%5Cdfrac%7B5%7D%7B0%7D%20)
which is undefined, because you can't divide by 0.
So, when defining this function, you have to specify
, so that the function will be defined for every other input.
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.

5^-4 x 5^6 = 25. This one should be on top
10^2 x 10^-1 = 10. This should be in the middle
1^0 x 1^10 = 1. This should be at the bottom
Answer:
74
Step-by-step explanation:
P(AD) + P(BD)
=(6x7) + (4x8)
=42+32
=74
