Snowcat [4.5K]

Answer:

E) none of the above

12.70% and 2.49% standard deviation

Explanation:

We multiply probability by the outcome to get the weighted amount, we add them and get the expected return.

probability outcome weighted

0.25          0.10   0.0250

0.45          0.12   0.0540

0.30          0.16   0.0480

expected return  0.1270

Now that we got the expected return at 12.7%

We now subtract the possible outcome with the expected return and square them:

(0.127-0.1)^2

(0.127-0.12)^2

(0.127-0.16)^2

Then we add them and divide by the sample which is 3

0.000622  

²√ 0.000622   = 0.024944383

<u><em>Final step,</em></u> will be the square root which gives the standard deviation

of 2.49% = 0.024947

A stock has annual returns of 5 percent, 21 percent, -12 percent, 7 percent, and -6 percent for the past five years. The arithme
sergij07 [2.7K]

Answer:

Arithmetic = 3%

Geometric = 2.37%

Explanation:

The arithmetic average of 'n' returns is given by:

A = \frac{\sum r_i}{n}

For five returns of 5% ,21%, -12%, 7%, and -6%:

A=\frac{0.05+0.21-0.12+0.07-0.06}{5}\\ A=0.03=3\%

The geometric average of 'n' returns is given by:

G=\sqrt[n]{(1+r_1)*(1+r_2)*...*(1+r_n)}-1

For five returns of 5% ,21%, -12%, 7%, and -6%:

G=\sqrt[5]{(1+0.05)*(1+0.21)*(1-0.12)*(1+0.07)*(1-0.06)}-1\\G=0.0237=2.37\%

<h3>What is the Parsons Thompson model?</h3>

The three layers or levels of the Parson and Thompson model describe what occurs in the enterprise and how a process or activity serves a particular goal.

Here is a summary of Thompson's levels of interdependence:

  • In order to create a team where each member contributes to the total, there are three types of interdependence that can be used.

In a business school, the degree of connection between the departments of finance and marketing is:

  • Structure of Reciprocal Interdependence.

There are various coordination techniques that might be applied to manage the interdependence, including:

  • complete cooperation
  • extensive preparation
  • Mutual apprehension

We must demonstrate the many layers of interconnectedness and how they might be applied in diverse systems, such as a business school's finance or marketing department, in order to answer the issue.
