Answer:
a. Z-test of a population mean.
Step-by-step explanation:
The current owner claims that over the past 5 years, the average daily revenue was $675 with a standard deviation of $75.

I don't understand what you're asking
There's an equation to find the length between 2 points on a plane.
√[(2-4)2 + (2-7)2] = √29
√[(4-6)2 + (7-2)2] = √29
√[(2-6)2 + (2-2)2] = 4
Therefore, Triangle ABC is an iscoceles triangle!
12.
3/4=0.75
0.75×4=3 (closest whole number)
4×3= 12
