Answer:
The margin of error is of 0.038 = 3.8%.
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
.
For this problem, we have that:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The margin of error is:



The margin of error is of 0.038 = 3.8%.
The answer is A. 540
540 divided by 2 = 270
540 divided by 3 = 180
The number 540 is also composite, which is required in your answer.
The other numbers do not end in 0,2,4,6 or 8, which is required to be divided evenly by 2. And only answer choices A. B. and C. can be evenly divided by 3.

Answer:
D x2 + y2 = 4
Step-by-step explanation:
The following are the functions
y = 4
y = x - 4
y = x^2 - 4
but
x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values
But the above equation does not meet the criteria so this represent non-function
