<h3>How to Identify the source of Bias?</h3>
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.

Answer:
63568 dollars
Step-by-step explanation:
Given that in your computer store you charge $1012 per computer sold. Your costs are given by the equation
where x is the number of computers sold.
Revenue = sales price *no of computers sold
= 1012x
Profit = Revenue - cost
= 
Use derivative test to find maximum profit
Equate I derivative to 0
x= 128
i.e. if 128 computers are manufactured and sold profit wouldbemaximum
Profit maximum=

Answer:
25 ft^2
Step-by-step explanation:
In direct variation, if y varies directly with x, then the equation has the form
y = kx,
where k is the constant of proportionality. y is proportional to x.
Let's call the area y and the distance x.
Here, the area varies with the square of the distance, so the equation has the form
y = kx^2
Here, y is proportional to the square of x.
We can find the value of k by using the given information.
y = kx^2
When x = 20 ft, y = 16 ft^2.
16 = k(20^2)
k = 16/400
k = 1/25
The equation of the relation is:
y = (1/25)x^2
Now we use the equation we found to answer the question.
What is y (the area) when x (the distance) is 25 ft?
y = (1/25)x^2
y = (1/25)(25^2)
y = 25
Answer: 25 ft^2
