Y=15/x or xy=15 it seems that a should be 15/x
Since <em>x</em> is the number of 14-year periods, the first thing we do is divide 28 years by 14. 28/14=2. Now we use that in our function,

.

There will be 220 foxes after 28 years.

Answer: 
Step-by-step explanation:
The confidence interval to estimate the population mean is given by :_

Given : Sample size : n= 60 , the sample is a large sample (n>30), so we can apply z-test.
Sample mean = 
Standard deviation : 
Level of confidence:

Then, critical z-value =
Then, a 95% confidence interval estimate of the population mean will be

Hence, the 95% confidence interval to estimate the population mean =
.
