Answer:
There is a 10% chance of the mean oil-change time of 20.53 minutes
Explanation:
Given that:
There are 45 oil changes between 10
a.m. and 12 p.m. treating this as a random sample, n = 45 and there would be a 10% chance of the mean oil-change time, therefore P = 10% = 0.1
A probability of 0.1 gives a corresponding z score of -1.28, this is gotten from the z table. z = -1.28
z score (z) = (x - mean) / (standard deviation / √n)
Let us assume mean = 21.2 minutes and standard deviation = 3.5 minutes. substituting values:
-1.28 = (x - 21.2)/(3.5 ÷ √45)
-1.28 = (x - 21.2) / 0.522
x - 21.2 = -0.6678
x = 21.2 - 0.6678 = 20.53
x = 20.53

Answer: $756
Explanation:
Based on the information given in the question, the fee that should be charged to obtain a contribution margin of 18% will be:
Target fee = Variable cost/(1-Contribution Margin)
= $620/(1 - 18%)
= $620/(82%)
= $620/0.82
= $756
They should charge $756
Answer:
The cost of producing one bottle is $10
.
Explanation:
The fixed costs of making the drug = $1 million
The selling price of the 50 pills bottles = $10
Total number of bottles sold at breakeven =200000
Total revenue from the sale of bottle = $10 × 200000
Total revenue from the sale of bottle = $2000000
Since at breakeven point the total revenue is equal to total cost. So, total cost of producing the 200000 bottles is $2000000.
Thus, the cost of producing one bottle = $2000000 / 200000 = $10
Answer:
2.88%
Explanation:
According to the fisher equation :
(1 + Nominal interest ) = (1 + real interest) (1 + inflation rate)
(1.07) = (1.04) x (1 + real interest)
(1.07) / (1.04) = (1 + real interest)
1.028846
real interest rate = 2.88%
