Solve for y means we need to isolate y from the equation:
We need to use inverse operations to solve equations:
Answer:

Step-by-step explanation:
If we assume that the number of arrivals is normally distributed and we don't know the population standard deviation, we can calculated a 95% confidence interval to estimate the mean value as:

where x' is the population mean value, x is the sample mean value, s is the sample standard deviation, n is the size of the sample,
is equal to 0.05 (it is calculated as: 1 - 0.95) and
is the t value with n-1 degrees of freedom that let a probability of
on the right tail.
So, replacing the mean of the sample by 49, the standard deviation of the sample by 17.38, n by 10 and
by 2.2621 we get:

Finally, the interval values that she get is:

Answer:
if you want an equation... an example could be
y=3x+5
