K=3,052
Step-by-step explanation:
18,010-14,958=3,052
C. s is your answer.
The sum of 2 angles on a straight line (supplementary angles) is 180°. Vertical angles (opposites where a line intersects) are equal.
The upper left and lower right angles where p crosses the other lines (q, r, t) are 105°.
180 - 105 = 75°
So the upper right and lower left angles are 75°. The lower left angle where p intersects s is 85°, so it is not parallel to the others.

Answer:
The sample size is 1875.
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:
Sampling error of 0.03.
This means that 
99.74% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
25% of all adults had used the Internet for such a purpose
This means that 
What is the sample size
The sample size is n. So
Simplifying by 0.03 both sides
The sample size is 1875.
