If I know what you're asking, the answer is theoretical probability.
Answer:
The required probability is 0.0855
Step-by-step explanation:
Consider the provided information.
The daily revenue has mean $7200 and standard deviation $1200.


The daily revenue totals for the next 30 days will be monitored.


As we know 
Substitute
in above formula.

From the standard normal table P( Z >1.3693) = 0.0855
Hence, the required probability is 0.0855

Step-by-step explanation:
I hope you dont have to show your work because I am not showing how you do all of those aha.
part 1:
1. p=72, a= 612
2. p=194, a= 32.5
3. p=300, a= 1500
4. p=221, a= 35
and um... I dont know how to do part two. sorry
Step-by-step explanation:
perpendicular means to cross at a right angle (90 degrees).
so, any line perpendicular to the x-axis is parallel to the y-axis.
and any line parallel to the y-axis has only a defining x value. all points on that line have the same x value (while any value for y from -infinity to +infinity is valid).
the y-axis itself is
x = 0
the specified point here has an x value of 4.
so, the line we are looking for is
x = 4
to point out : this is NOT a function, because for the same x value we get more than 1 valid y values.
