Step-by-step explanation:
![\left|\begin{array}{cccc}$Brand&$Total Sold&$Returns&$Probability of Returns\\---&---&---&---\\$Brand A&343&17&\dfrac{17}{343}=0.0496 \\\\$Brand B&180&14&\dfrac{14}{180}=0.0778 \\\\$Brand C&383&16&\dfrac{16}{383}=0.0418\\\\$Brand D&246&8&\dfrac{8}{246}=0.0325\\&&&\end{array}\right|](https://tex.z-dn.net/?f=%5Cleft%7C%5Cbegin%7Barray%7D%7Bcccc%7D%24Brand%26%24Total%20Sold%26%24Returns%26%24Probability%20of%20Returns%5C%5C---%26---%26---%26---%5C%5C%24Brand%20A%26343%2617%26%5Cdfrac%7B17%7D%7B343%7D%3D0.0496%20%5C%5C%5C%5C%24Brand%20B%26180%2614%26%5Cdfrac%7B14%7D%7B180%7D%3D0.0778%20%5C%5C%5C%5C%24Brand%20C%26383%2616%26%5Cdfrac%7B16%7D%7B383%7D%3D0.0418%5C%5C%5C%5C%24Brand%20D%26246%268%26%5Cdfrac%7B8%7D%7B246%7D%3D0.0325%5C%5C%26%26%26%5Cend%7Barray%7D%5Cright%7C)
We can see from the table above that the experimental probability of returns of Brand B is the highest, therefore it has the highest likelihood of being returned.
The store should consider eliminating Brand B.
Answer: 4
Since we need to find the y, we're going to substitute the x's with the numbers in the x column.
Let's try to find the first y box.
We're going to substitute all of the x's with -0.5.
y = 4(-0.5)^2 - 8(-0.5) + 4
Now, we're just going to solve that.
-2^2 - 4 + 4
-2 squared is 4. It's a positive 4 because a negative times a negative is a positive.
4 - 4 + 4
= 4
