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 = ![\frac{x-mean}{standard deviation}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx-mean%7D%7Bstandard%20deviation%7D%20%20)
= ![\frac{2100 - 2000}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2100%20-%202000%7D%7B100%7D%20%20)
Z = 100/100
Z = 1
The z score for income $2100 is 1
Well it depends on the type of crayon box that she buys. For instance, some crayon boxes have a 24 pack box of crayons while others have 64 or maybe even a 16 pack box of crayons. So it all depends on what kind of box she bought.

its like a pack of 12 magazines costing $36 and you asked the cost of one magazine
by proportion; let average be=?
12~$36
1~?
1/12=?/36
?=(1/12)*36
?=3=average
Answer:
y = 3x -13
Step-by-step explanation:
