You have a $15,000 portfolio which is invested in Stocks A and B, and a risk-free asset. $6,000 is invested in Stock A. Stock A

DerKrebs [107]

Answer:

$7073.68

Explanation:

Data provided in the question:

Worth of portfolio = $15,000

Amount invested in stock A = $6,000

Beta of stock A = 1.63

Beta of stock B = 0.95

Beta of portfolio = 1.10

Now,

Beta portfolio = ∑(Weight × Beta)

let the amount invested in Stock B be 'x'

thus,

1.10 = [($6,000 ÷ $15,000 ) × 1.63] + [( x ÷ $15,000 ) × 0.95 ]

1.10 = 0.652 + [( x ÷ $15,000 ) × 0.95 ]

0.448 = [( x ÷ $15,000 ) × 0.95 ]

x = ( 0.448 × $15,000 ) ÷ 0.95

x = $7073.68

The Federal Reserve System and the New York Stock Exchange regulations currently require the short seller to have an initial mar

lutik1710 [3]

Answer:

Correct answer is 50%

Explanation:

The appropriate response is half.

The Regulation T of the Federal Reserve Board requires the equalization for all short deal records to be at any rate 150% of the estimation of the protections at the time the deal is started.

This implies when the short deal is started, as we are selling the offers first, our record will have the 100% estimation of the offers sold (as we receipts of cash from selling) in addition to an extra edge prerequisite of half of the estimation of the short deal.

For instance, on the off chance that I am short selling an offer whose cost is $100, at that point when I short sell the offer, my record equalization will become $100, as receipts of the deal.

Along these lines, at the hour of inception of offer, my record equalization ought to be 150% of the estimation of short deal = 150% of $100 = $150. The separation of this sum is

100% of $100 = $100, which gets credited to my record

in addition half of $100 = $50, which is the edge necessity at the inception of short deal.

In this way, Initial edge necessity is atleast half of the cost of the stock.

The student ought not befuddle the underlying edge necessity with the base upkeep edge.

The base support edge required to be kept up is 25%. This implies the short dealer ought to consistently have an edge (not balance) of 25% in the record. In the event that the edge goes beneath 25%, at that point the edge require the distinction sum is actuated, which the short dealer is required to pay to keep on keeping her situation in the market unaltered.

Be that as it may, beginning edge required to be kept up is half.

On October 1, Black Company receives a 10% interest-bearing note from Reese Company to settle a $22,200 account receivable. The

lorasvet [3.4K]

Answer:

$555

Explanation:

The computation of the interest revenue is shown below:

= Account receivable × rate of interest × number of months ÷ (total number of months in a year)

= $22,200 × 10% × (3 months ÷ 12 months)

= $2,220 × (3 months ÷ 12 months)

= $555

The three month is calculated from October 1 to December 31. The six month period of note is ignored

A body in the solar system has a period of 10,759.22 days and a perihelion speed of 10.18 km/s. a. Calculate the aphelion radius

anastassius [24]

Answer:

Explanation:

From the information given, by applying Kepler's 3rd law,

$T^2 \alpha a^3$

where;

T = period

a = semi major axis

T = 356 days (for earth)

a = 1 AU = 1.496 $\times 10^8 \ km$

Therefore, $T^2 = ca^3$

$c= \dfrac{365^2}{(1.496 \times 10^8)^3}$

c = 3.9791 $\times 10^{20} \ day^2/km^3$

However, if the body in the solar system has a period of 10.759.22 days, then, a =?

∴

$T^2 = ca^3$

$a3 = \dfrac{10759.22^2}{3.9791 \times 10^{-20}}$

$a^3 = 2.9092 \times 10^{27}$

$a= \sqrt[3]{2.9092 \times 10^{27}}$

a = 1.4275 $\times 10^9 \ km$

However, the velocity for a perihelion = 10.18 km/s

Using the formula

$v = \sqrt{GM ( \dfrac{2}{r}-\dfrac{1}{a})}$ to calculate the radius, we have:

G = $6.674 \times 10^{-11}$

M = $1.989\times 10^{30} \ kg$

r = perihelion

$v ^2= GM ( \dfrac{2}{r}-\dfrac{1}{a})$

$(10.18 \times 10^3) ^2= 6.674 \times 10^{-11} \times 1.989 \times 10^{30} ( \dfrac{2}{r}-\dfrac{1}{1.425 \times 10^{12}})$

$7.8068 \times 10^{-13}= \dfrac{2}{r}-\dfrac{1}{1.425 \times 10^{12}}$

$\dfrac{2}{r} = 1.4824 \times 10^{-12}$

$r = \dfrac{2}{1.4824 \times 10^{-12}}$

$r = 1.349 \times 10^{12}$

Similarly, the perihelion is expressed by the equation,

r = a(1 - e)

where ;

e= eccentricity

∴

$1.349 \times 10^{12} = 1.425 \times 10^{12} ( 1 - e)$

$1.349 \times 10^{12} - 1.425 \times 10^{12}= - 1.425 \times 10^{12} (e)$

$-7.6\times 10^{10}= - 1.425 \times 10^{12} (e)$

$\dfrac{-7.6\times 10^{10}}{- 1.425 \times 10^{12}}= (e)$

e ( eccentricity) = 0.0533

Aphelion radius in natural miles, r = a( 1+ e)

$r = 1.425 \times 10^{12} ( 1 + 0.0533)$

$r = 1.50 \times 10^{12} \ m$

to nautical miles, we have:

$r = 1.50 \times 10^{12} \times 0.00054 \ nautical \ mile$

radius of aphelion $\mathbf{r = 8.10 \times 10^8}$ nautical miles

In respect to the value of a( i.e $1.4275 \times 10^9 \ km)$

the body of the solar system is Saturn

kramer

Answer:

The correct answer is the option C: Conducting the job analysis.

Explanation:

To begin with, the term of <em>"Job Analysis"</em> refers to a method used in the organizations with the purpose of generating job descriptions and specifications in order to establish a better communication inside the organization and also to know better who the best candidates will be for future jobs. Therefore that this analysis focus on the correct comprehension from the analyst regarding the job that is being under analysis. When the analysis has began the person in charge of it will have to planned carafully the way that she will get the information for later transform it into the job description and that is why that once that the planning has been done the person needs to conduct the job analysis in order to obtain the results expect that are the proper description of the job and all of its specifications for future employees.
