Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
Answer:
Economic models often vary greatly in assumptions and simplifications.
Explanation:
Most models in Classical Economics are based on a lot of generalizations and simplifications, that intend to model the behavior of the situations of the real world but often fail to encompass all the intricacies and complications that even most straightforward situations present. These simplifications help the Economists figure out the mathematical laws that are governing the real world economic systems. Therefore making the economic modeling a simpler process.
Classic economics implies three basic assumptions:
1- People behave rationally in any situation.
2- Firms and individual want to maximize profit and utility
3- People act independently based on available information.
Answer:
Line
Explanation:
The line organization is the organization structure in which the authority and responsibility are communicated from the top to bottom level of management so that the proper coordination could be done at each level of management i.e top, middle and lower.
Moreover, it is a two ways lines of responsibility i.e to be communicated from high to low level of management. Plus it would be reported to one supervisor only
Answer:
a. $28
b. $19
c. 800 watches
Explanation:
The equation is
p = D(q) = 28 - 2.25
The equation of the demand would be
P = 28 - 2.25q
a. The price would be
= $28 - 2.25 × 0
= $28 - 0
= $28
b. The price would be
= $28 - 2.25 × 4
= $28 - 9
= $19
The quantity demanded is come in hundreds so we take only 4
c. The quantity woul dbe
$10 = $28 - 2.25q
$10 - $28 = -$2.25q
-$18 = -$2.25q
So q would be
= 800 watches
Answer:
B. make it unequivocally clear that the company's core values and ethical standards are strictly enforced cultural norms.
Explanation:
Once values and ethical standards have been formally adopted, a company must make it unequivocally clear that the company's core values and ethical standards are strictly enforced cultural norms.
This ultimately implies that, when an organization has developed its policy which normally connotes its values and ethical standards, it is very important and essential that it communicates succinctly to its employees they must abide by this policy and must be strongly adopted and adhered to by them.
