X then y
So add 7 to -1=6 which is x
Moving left is still x
So subtract 6-5= 1 is now x
So the coordinates are{1,-2)

Answer:
The margin of error for a 99% confidence interval for the population mean is 1.8025.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem:
So
The margin of error for a 99% confidence interval for the population mean is 1.8025.
Use the ticket price in the first column in the formula 400-7p to get the answer for the second column (number of tickets sold)
Then multiple the number to f tickets in the second column by the price in the first to determine the revenue.
