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
Answer:
m(x)= 0 when X= 3
Step-by-step explanation:
2*3=6
6-6=0
For (2x-6)
3-4=-1
So -1*0=0
it can also be look at like this (0,-1)
