Answer:
Step-by-step explanation:
Given that a cola-dispensing machine is set to dispense a mean of 2.02 liters into a bottle labeled 2 liters.
Std deviation =0.015 litres
X- litres contained in a bottle is N(2.02, 0.15)
Z score is obtained as
a) probability a bottle will contain between 2.00 and 2.03 liters
=P(2<x<2.03) = P(-1.33<Z<2)
= 0.4082+0.4772
=0.8854
b) P(X<2) = P(Z<-1.33) =0.5-0.4082 = 0.0918
c) 2% of containers
|z|<0.11
X lies between 0.6883 and 3.352 l
Brad's profit was 30%
Further explanation:
Profit is the money someone earns on selling a product on more than its actual cost.
The formula for profit is:
Given
Purchase price of energy drinks = £9.25
Selling price of one bottle=£1
Selling price of 12 bottles=1*12=£12
Profit= Selling Price - Purchse price
=12-9.25
=£2.75
Brad's profit was £2.75
Now,
Profit percentage= (Profit/Purchase Price)*100
=(2.75/9.25)*100
=0.30*100
=30%
Brad's profit was 30%
