Answer:
A, c(excluding tip, if the tip is included then c is not the answer)
Step-by-step explanation:
I solved the Equations:
A)1/8(x+16)=76/8----60 (this is the correct answer!)
B)1/8(x+16=76)------ 592 (NOT the correct answer
c)x=60 Represents total food bill excluding tip
d) x=60 does represent each friends share of the food bill
E) not correct
Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.
μ =2000, σ =100
We have to find z score for income $2100 i.e x=2100
Z = 
= 
Z = 100/100
Z = 1
The z score for income $2100 is 1
You weren't clear on the equation so I did it both ways. It didn't really matter though because both equations had the same answer. ♀️
Step-by-step explanation:
the problem description is incomplete or wrongly copied.
we don't know the thickness of the boards, and we cannot understand what we need to calculate, and what the answer options are.
An equation is something with a = sign btw and it’s C because it’s the only one with the = sign
