Answer:
C. 50
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want a widest possible interval, we should select the smallest possible confidence interval.
So the correct answer is:
C. 50
When doing this, we would have to first straight them all out, and as we see above, they are just all over the place, and then, we would have to set them up as a sequence.
![\left[\begin{array}{ccc}5x2 + 5y2 - 20x + 30y + 40 = 0\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5x2%20%2B%205y2%20-%2020x%20%2B%2030y%20%2B%2040%20%3D%200%5Cend%7Barray%7D%5Cright%5D%20)
would be our first step in this problem mainly because it contains the most terms in this aspect.
Then we would then
, then, 
.
These would only be our first 3 part of the sequence in this aspect.
The others would then be the following:
Thus, as we would have one more afterward, our last part of the sequence would then be the following.
I hope this was found helpful!
