Incomplete question
First aspect of the question is typed below.
The shape of the distribution of the time required to get an oil change at a 20-minute oil-change facility
is unknown. However, records indicate that the mean time is 2l.2-minutes, and the standard deviation 3.5 minutes.
Explanation:
Employees bonus $50
35 oil changes between 10:00 am to 12:00pm
n = 35
10% changes
So, the z - score can be calculated using
z-score = InvNorm(0.10)
z-score = -1.28
So, given that,
Standard deviation is 3.5minutes
σ = 3.5 minutes
Mean time is 21.2 minutes
μx = 21.2 minutes
Then,
σx = σ / √n
σx = 3.5 / √35
σx = 0.5916 minutes
Then, Z score can be written as
Z = (x - μx) / σx
-1.28 = (x - 21.2) / 0.5916
Cross multiply
-1.28 × 0.5916 = x - 21.2
-0.7573 = x - 21.2
x = 21.2 - 0.7573
x = 20.443 minutes
There is a 10% chance of being at or below a mean oil-change time of 20.44 minutes
Answer:
The expected rate of return is 8.65%
Explanation:
The expected return on a stock can be calculated by multiplying the return in each scenario by the probability of that scenario. This will provide the expected value of the return based on all these scenarios. Thus, the rate of return is,
Rate of return = rA * pA + rB * pB + rC * pC
Where,
- r represents the return in each scenario
- p represents the probability of each scenario
The probability of normal state is = 1 - 0.45 - 0.05 = 0.5
Rate of return = 0.13 * 0.45 + 0.06 * 0.5 + (-0.04) * 0.05
Rate of return = 0.0865 or 8.65%
Answer:
1999 Merger of Exxon and Mobil
The reason that made the U.S. government to require Exxon and Mobil to divest themselves of so many gas stations in localized parts of the country to be willing to allow the merger to occur is:
c. To ensure competition in these regions and protect consumers from unwarranted price increases.
Explanation:
The agreement to sell so many gas stations in localized parts of the country was to forestall antitrust lawsuits. It was also made to protect consumers from unwarranted price increases, allowing more competition in the affected areas, where ExxonMobil owed too many gas stations.
Based on the payment you can afford, the interest rate, and the number of years, the loan you can afford is $6,774.15
<h3>What size of a loan can you afford?</h3>
First find the monthly interest rate:
= 4% /12
= 1/3%
Number of periods:
= 3 x 12
= 36 months
The loan you can afford can be found as:
= Payment x ( 1 - (1 + rate) ^ -number of periods) / rate
= 200 x (1 - (1 + 1/3%)⁻³⁶) / 1/3%
= $6,774.15

Answer: See explanation
Explanation:
a. The Law of Demand states that when the price of a good rises, then the Quantity Demanded will (fall)
b. The Law of Demand states that when the price of a good falls, then the Quantity Demanded will (rise).
According to the law of demand, when there's an increase in the price of a product, there'll be a reduction in the quantity of the good that will be demanded by the consumers and vice versa.
