Answer:
B) greater than $30 but less than $40
Explanation:
the options are missing:
A) less than or equal to $30
B) greater than $30 but less than $40
C) greater than $40 but less than $50
D) greater than $50
we must first calculate safety stock = (Z-score x √lead time x standard deviation of demand) + (Z-score x standard deviation of lead time x average demand)
- Z-score for 98% confidence level = 2.326
- standard deviation of demand = 30
- √lead time = √5 = 2.23607
- we are not given any standard deviation of lead time, so we can assume that it is 0
safety stock = (2.326 x √2.23607 x 30) + (2.326 x 0 x 300) = 156.03 ≈ 156 units
the annual holding cost of 156 units = 156 x $0.25 = $39
Answer:
Explanation:
See the attached for a spreadsheet of the values given in the problem statement. We have simply added the salary to the value of the preference and subtracted the one-time moving expense.
The right-most column shows the net increase in value of moving to Miami for each of the householders. Bonnie achieves so much more value that her net value outweighs the rather significant hit in value that Donna experiences.
If the vote is by net value to the householders, they must vote to move. There are no householders that have a net zero change in value.

A decision based on net value does not account for the rather significant cost to Donna. If the household values mental health and interpersonal relationships, the fact that one member suffers badly from the move should be enough to sway the decision against it.
Answer:
D. Limited Partnership
Explanation:
Sole proprietorship is business owned , run & managed by single owner. Partnership is a business owned , run & managed by small group of people - deciding to share its profits .
Entrepreneurs in these have Unlimited Liability on personal assets, in case business assets are insufficient to settle business liabilities .
Corporation is a separate legal entity, distinct from its huge group of owners , guided by a board of directors. In case of any claim / sue case : it is against corporate entity & not the people, so they don't have any unlimited liability risk on personal assets to fulfil company's claims .
The waiting time at which 10 percent of the people would continue to hold is given as 2.3
<h3>How to solve for the waiting time</h3>
We have to solve for X ~ Exponential(λ).
then E(X) = 1/λ = 3,
= 0.3333
Remember that the cumulative distribution function of X is F(x) = 1 - e^(-λx). ; x is equal to the time in over case
For 10 percent of the people we would have a probability of
10/100 = 0.1
we are to find
P(X ≤ t)
= 1 - e^(0.3333)(t) = 0.1
Our concern is the value of t
Then we take the like terms
1-0.1 = e^(0.3333)(t)
1/0.9 = e^(0.3333)(t)
t = 3 * ln(1/0.9)
= 0.3157
