The source of bias that affected the confidence interval, but is not included among the sources covered by the margin of error is; Under coverage Bias
The reason why I picked under coverage bias is because we see from the survey that they send a survey home with a random sample of students in the district. However, when the survey was not completed, calls are made to ensure responses are obtained from the parents of every selected student. Then the question is changed again.
Thus, it is clear that not all was captured and that is why we go with under coverage bias.

Using the intersecting chord theorem:
15 x 2 = 5 x n
Simplify:
30 = 5n
Divide both sides by 5:
n = 30/5
n = 6
Answer:
887.74

Answer:
x = 3/5
Step-by-step explanation:
15x+3(5x-3) = 9
15x+15x-9 =9
30x-9 = 9
30x-9+9 = 9+9
30x = 18
x = 18/30
x = 3/5
Answer:
He didn't calculate the b-value correctly.
Step-by-step explanation:
The given parent function is:
The transformation is of the form:
The period is given by
If we want the new function to have a period of
Then we solve the following equation for b.
will translate the graph horizontally to the right by
units.
+d shifts the graph up by d units.
The new function then becomes:
