Answer: 115 degrees
Step-by-step explanation:
Since a kite has one pair of opposite angles which are congruent, W and Y must be congruent because X and Z are not.
The sum of the angles in any quadrilateral is 360 degrees. We know two of the angles as 90 degrees and 40 degrees, so the sum of the other two angles must be 360-90-40 = 230 degrees.
We know that W and Y must be equal so each of them is equal to 230/2 degrees = 115 degrees.
Answer:
True
Step-by-step explanation:
a negative number like -6 which would be found on the left of the number line is not larger than 2 which is found on the right side of the number line.
Using the z-distribution, it is found that the 95% confidence interval for the proportion of all seafood sold in the United States that is mislabeled or misidentified is (0.3036, 0.3564).
<h3>z-distribution interval:</h3>
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
.
For this problem:
- 1215 samples, hence
.
- 33% was mislabeled or misidentified, hence
.
- 95% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
<h3>The lower limit of this interval is:</h3>

<h3>The upper limit of this interval is:</h3>

The 95% confidence interval for the proportion of all seafood sold in the United States that is mislabeled or misidentified is (0.3036, 0.3564).
