An equation solution is simply the limit for an inequality. So if it is a < or > then the solution does not include the solution for the quation, but everything below or above it (depending on the sign of the inequalities). If the inequality is <= or => then the solution would include the solutions for the equation.

OMGGGG OMGGG I NEEDTHIS QUESTION TOOOOOO
Because it goes up for a constant rate, to find the rice for 1 hour of parking do 16.00-12.50 and get 3.50 . To find the fee, just subtract 12.5 - 3.5
The fee for parking is $9
Hope this helps
Answer: (a) ![13.046](https://tex.z-dn.net/?f=13.046%3C%5Cmu%3C%2022.15)
(b) The best point estimate of
is the sample mean ![=17.598](https://tex.z-dn.net/?f=%3D17.598)
The margin of error = 4.552
Step-by-step explanation:
Given : The confidence interval for the population mean = (13.046 , 22.15)
Sample mean : ![\overline{x}=17.598](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%3D17.598)
Standard deviation : ![\sigma= 16.01712719](https://tex.z-dn.net/?f=%5Csigma%3D%2016.01712719)
Sample size : ![n=50](https://tex.z-dn.net/?f=n%3D50)
a. Let
represents the population mean.
Then we can write the confidence interval for the population mean as :-
![13.046](https://tex.z-dn.net/?f=13.046%3C%5Cmu%3C%2022.15)
b. The best point estimate of
is the sample mean ![=17.598](https://tex.z-dn.net/?f=%3D17.598)
Also, the lower limit of confidence interval can be written as
![\overlien{x}-E](https://tex.z-dn.net/?f=%5Coverlien%7Bx%7D-E)
i.e. ![\overlien{x}-E=13.046](https://tex.z-dn.net/?f=%5Coverlien%7Bx%7D-E%3D13.046)
![E=\overline{x}-13.046=17.598 -13.046=4.552](https://tex.z-dn.net/?f=E%3D%5Coverline%7Bx%7D-13.046%3D17.598%20-13.046%3D4.552)
Hence, the margin of error = 4.552
