Answer:
(-2, 1)
Step-by-step explanation:
Hi Juliadayx! How are you?
Well, maybe you already heard about the domain and the range of a function.
The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.
In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).
I hope I've been helpful!
Regards!

Answer:
0.0000269
Step-by-step explanation:
Given that a researcher is looking for 10 people to participate to a medical study on diabetes.
Suppose the researcher has to find his 10 participants, out of 25, then he has to get 9 participants in 24 trials, and the last one in 25th trial
Out of 24 trials, 9 participants selecting is binomial with p =0.1 because there are only two outcomes and each trial is independent of the other.
Hence Prob for selecting 9 from 24 = Prob for 9 successes in 24 trials
=P(X=9)
=
...i
the probability that the researcher will have to call 25 candidates in order to find his 10 participants
= i * prob for 25th trial success
= ![0.000269(0.1)\\=0.0000269](https://tex.z-dn.net/?f=0.000269%280.1%29%5C%5C%3D0.0000269)
