- Parallel lines are lines that never meet and which are straight.
- Perpendicular lines are lines that intersect at a 90° angle.
A picture of different types of lines will be shown below
A picture of the graph will be shown below.
Looking at the graph, we can see that lines intersect and seem to have a 90°.
Therefore, they are perpendicular.
Best of Luck!

Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
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 z-score that has a p-value of .
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that
95% confidence level
So , z is the value of Z that has a p-value of
, so
.
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
