What is the probability of receiving at least three e-mails during an hour (to 4 decimals)? For this question, if calculating the probability manually make sure to carry at least 4 decimal digits in your calculations. c. What is the expected number of e-mails received during minutes (to 2 decimals)? d. What is the probability that no e-mails are received during minutes (to 4 decimals)?
Answers
b) The probability of receiving at least three e-mails during an hour is of: 0.8754 = 87.54%.
c) The expected number of e-mails received during 15 minutes is of: 1.25 e-mails.
d) The probability that no e-mails are received during 15 minutes is of: 0.2865 = 28.65%.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following mass probability function defines as follows:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successes that we want to find the probability of.e = 2.71828 is the Euler number.[tex]\mu[/tex] is the mean in the given interval or range of values of the input parameter.The daily mean is of 121 e-mails, hence the hourly mean is of:
[tex]\mu = \frac{121}{24} = 5[/tex]
Then the probability of at least three e-mails during the hour is of:
P(X ≥ 3) = 1 - P(X < 3)
In which:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
Hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-5}(5)^{0}}{(0)!} = 0.0067[/tex]
[tex]P(X = 1) = \frac{e^{-5}(5)^{1}}{(1)!} = 0.0337[/tex]
[tex]P(X = 2) = \frac{e^{-5}(5)^{2}}{(2)!} = 0.0842[/tex]
Then:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0067 + 0.0337 + 0.0842 = 0.1246
Hence:
P(X ≥ 3) = 1 - P(X < 3) = 1 - 0.1246 = 0.8754 = 87.54%.
The mean during 15 minutes is one-fourth of the hourly mean, hence:
5.04/4 = 1.25 e-mails.
The probability of no-emails during the 15 minutes is of:
P(X = 0) = e^(-1.25) = 0.2865 = 28.65%.
Missing InformationIn items c and d, the measure is of 15 minutes, and the description of the problem is given by the image shown at the end of the answer.

If the government imposes a price floor at $10, it would be:
C) non-binding if market demand is Demand A and binding if market demand is Demand B.
In this scenario, the price floor is non-binding for Demand A if the equilibrium price is already above $10, meaning that the market price naturally remains above the price floor.
However, the price floor becomes binding for Demand B if the equilibrium price is below $10, forcing the market price to stay at the imposed $10 level.
It's important to note that when a price floor is binding, it can create several consequences, including:
a. Surplus: As mentioned, a binding price floor may lead to a surplus of the product. Suppliers are willing to sell a larger quantity at the higher price floor, but demand is insufficient to meet that level of supply.
b. Inefficient Allocation: The binding price floor may result in an inefficient allocation of resources since some willing buyers are excluded from the market due to the higher price.
c. Potential Government Interventions: The government may need to implement measures to manage the surplus, such as purchasing excess supply or providing subsidies to support producers.
In summary, a price floor is considered non-binding if the equilibrium price is already above the set minimum price. However, if the equilibrium price is below the price floor, the price floor becomes binding, leading to potential consequences such as a surplus and inefficient resource allocation.
The impact of a price floor depends on the specific market conditions and the relationship between the price floor and the equilibrium price.

how would you evaluate the courts claim that giving a gift of trading information is the same thing as trading by the tipper followed by a gift of the proceeds?
Answers
Answer:
Explanation:
To evaluate the courts claim that giving a gift of trading information is the same thing as trading by the tipper followed by a gift of the proceeds, it is necessary to consider the legal definitions and implications of these actions.
Under the law, trading on inside information, or "tipping," is illegal if it is done for personal gain or to benefit someone else. This is because it allows individuals to profit from non-public information that others do not have access to, which can be unfair and harmful to the market.
However, if the tipper simply provides the inside information as a gift, without any expectation of receiving anything in return, this may not be considered illegal. In this case, the tipper is not personally profiting from the information and is not directly benefiting anyone else through the gift.
Therefore, the courts claim that giving a gift of trading information is the same thing as trading by the tipper followed by a gift of the proceeds may not be entirely accurate. While both actions involve the sharing of inside information, the motivations and implications of these actions are different and may be treated differently under the law.

If Sunland Company is considering buying a machine for $240,000 with an estimated life of ten years and no salvage value. The cash payback period on this investment is: c. 8 years.
How to find the Cash payback periodFirst step is to calculate the depreciation using this formula

I believe I am not able to contribute much during a problem-solving process, even though I might be able to provide valuable inputs. Since I end up delaying my final decision, I miss opportunities to present solutions due to my lack of time management.

If a scenario occurred where supply decreased and led to an increase in price, as it happened with oil, the economy will work to adjust the aggregate supply curve back to equilibrium.
