Answer:

For the new set of marks, the median is of 55

Step-by-step explanation:

The median is the halfway point of a dataset, that is, the value that separates the lower 50% of the data set from the upper 50%.

In a data set, if we subtract or add all marks by x, the median will be subtracted or added by x.

In this question, we have that:

Median 65

From all marks, 10 is subtracted.

So, for the new set of marks, the median is of 65 - 10 = 55

Desreumaux Inc's stock has an expected return of 12.25%, a beta of 1.25, and is in equilibrium. If the risk-free rate is 5.00%,
zhenek [66]

Answer:

MRP=\frac{12.25\% -5.00\%}{1.25}=5.8 \%

Step-by-step explanation:

Previous concepts

The Capital Asset Pricing Model (CAPM) is a concept that "analyze the relationship between risk  of any type and the definition of expected return  about the assets".

By definition the Market risk premium is defined as "the difference between the average return and the return on a risk-free".

The value of  \beta represent an adimensional number that allows to measure if we create more/low risk on any investment.  

Solution to the problem

Assuming that we can use the capital asset pricing model we can calculate the market risk premium (MRP) with the following formula:

MRP= \frac{ER -RFR}{\beta}

Where:

ER= Expected return = 12.25 %

RFR= Risk free rate= 5.00%

\beta = 1.25

So then if we replace we got:

MRP= \frac{12.25\% -5.00\%}{1.25}=5.8 \%

What is the surface area of the triangular prism? A triangular prism. The base is 6 feet by 9 feet. The 2 rectangular sides are
Darina [25.2K]

Answer:

  168 ft²

Step-by-step explanation:

The area of the two triangular bases is ...

  total base area = 2×(triangle area) = 2×(1/2)bh = (6 ft)(4 ft) = 24 ft²

The lateral area of the prism is the product of the triangle perimeter and the height of the prism.

  lateral area = (6 ft + 5 ft + 5 ft)(9 ft) = 144 ft²

The surface area is the sum of the base area and the lateral area:

  surface area = base area + lateral area

  surface area = 24 ft² +144 ft² = 168 ft²

The surface area of the prism is 168 square feet.
