Answer:
22
Step-by-step explanation:
5/3=x-4/2
10=x-12
x=22
Rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.

What is the range?</h3>
- In mathematics, the range of a function can refer to one of two notions that are closely related.
- The function's codomain, the function's visual representation.
- A binary relation f between two sets X and Y is a function if for every x in X there is exactly one y in Y such that f relates x to y.
To find the rejected masses:
- If each pack of trail mixes is supposed to weigh 9.25 oz and must be within 0.23 oz of that weight to be accepted, then rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.
Therefore, rejected masses x are those that weigh less than 9.02 oz or more than 9.48 oz.

The correct question is given below:
A company did a quality check on all the packs of trail mix it manufactured. each pack of trail mix is targeted to weigh 9.25 oz. a pack must weigh within 0.23 oz of the target weight to be accepted. what is the range of rejected masses, ×, for the manufactured trail mixes?
Answer: C
Step-by-step explanation:
Answer:
The upper bound of a 99% confidence interval for the percentage satisfied for all customers in the database is 88.70%.
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 
.
Sample of 252 customers, 208 are satisfied:
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The upper limit of this interval is:
As a percentage:
100%*0.8870 = 88.70%
The upper bound of a 99% confidence interval for the percentage satisfied for all customers in the database is 88.70%.
