Answer:
22 people would be expected to participate in the survey.
Step-by-step explanation:
We are given that a research company found that 11% of the people that they called agreed to participate in a survey.
The company called 196 people and we have to find that how many would be expected to participate in the survey.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 196 people
r = number of success
p = probability of success which in our question is probability
that people agreed to participate in a survey, i.e; p = 11%
Let X = <em><u>Number of people who agreed to participate in a survey</u></em>
SO, X ~ Binom(n = 196, p = 0.11)
Now, the expected number of people who would participate in the survey is given by;
E(X) =
= = 21.56 ≈ <u>22 people</u>
<u></u>
Hence, 22 people would be expected to participate in the survey.
Answer:
I'm assuming (4,2) since its not gathered with the other points
Solution of the equation:
Step-by-step explanation:
The equation that we have to solve in this problem is:
The first step to do is to rewrite the mixed fractions as improper fractions. We have:
And
So the equation becomes
Now we multiply by 4 each term on both sides, and we get
Now we subtract 29 from both sides,
And finally, we divide both sides by 4:
