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
a. The store charges $94.5 for the skis
b. 150% of the original price is the final price
Step-by-step explanation:
The given is:
- A store that sells skis buys them from a manufacturer at a wholesale price of $63
- The store’s markup rate is 50%
We need to find at what price the store charges its customers for the skis and
what percent of the original price is the final price
∵ The store buys the skis at $63
∴ The cost price of the skis = $63
∵ The store’s markup rate is 50%
- Find the amount of 50% of the cost price
∵ 50% of 63 = × 63 = 31.5
∴ the store's markup the cost of the skis by $31.5
- To find the selling price add 31.5 to the cost price
∴ The selling price of the skis = 63 + 31.5 = $94.5
a. The store charges $94.5 for the skis
To find what percent of the original price is the final price divide the final price by the original price then multiply the quotient by 100%
∵ 94.5 ÷ 63 = 1.5
∵ 1.5 × 100% = 150%
∴ The final price is 150% of the original price
b. 150% of the original price is the final price
