Answer:
Option (C)
Step-by-step explanation:
In this question we will use the property " similarity of the triangles".
If DE and AC are parallel two triangles BED and BCA will be similar, corresponding sides of the triangles will be proportional.
Option (A).
But
Therefore, given triangles are not similar.
AC and DE are not parallel.
Option (B).
But
Therefore, AC and DE are not parallel.
Option (C).
2.5 = 2.5
Therefore, AC║DE.
Option (D).
But
Therefore, AC and DE are not parallel.
Option (C) will be the answer.

Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
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 lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
