Step-by-step explanation:

Suppose each stock in Andre’s portfolio has a correlation coefficient of 0.40 (rho = 0.40) with each of the other stocks. The market’s average standard deviation is approximately 20%, and the weighted average of the risk of the individual securities in the partially diversified four-stock portfolio is 39%. If 40 additional, randomly selected stocks with a correlation coefficient of 0.30 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio’s standard deviation?

Answers

Answer:

Explained below.

Step-by-step explanation:

The correlation coefficient for the portfolio with each of the other stocks is 0.40.

This correlation coefficient is less than 1. This implies that the portfolio’s assets are weakly correlated with each other.  

The portfolio profits from modification. Randomly selected stocks are added to the portfolio.  

The correlation coefficient of these stocks with the other stocks in the portfolio is about 0.30.  

Therefore adding these randomly selected stocks will decrease the portfolio’s standard deviation.  

Company-specific risk in portfolio can be reduced by this diversification but systematic or market risk can’t be eliminated. Thus the risk will (σ) decrease slowly until σp reaches to the average standard deviation of returns on the market i.e. about 20 %.

For the rate, r, for sam to change all the light bulbs in the office building by himself?

One job is involved

3r = 1 - 3/8

r = 1/3 - 3/8÷3

the figure below is a rhombus y = ?

Answers

Answer:

y = 28°

Step-by-step explanation:

The opposite angles of a rhombus are congruent.

The diagonal divides the rhombus into 2 isosceles triangles, as all sides are congruent.

Thus the triangle containing base angles y and w has vertex = 124°

Since the triangle is isosceles then the base angles are congruent , thus

y = [tex]\frac{180-124}{2}[/tex] = [tex]\frac{56}{2}[/tex] = 28°

Sam decides to download some new music. She downloaded 3 albums and 10
singles, and her total was $61. The next day she purchased more music from the
same retailer and downloaded 6 more albums and 8 singles for a total of $74.
Assuming that all albums and singles are the same price, how much did she spend on
each album and each single? Write a system of equations to represent this
situation. Then solve for the solution using the elimination method.

Answers

Answer:

An album costs $7 while a single cost $4

Step-by-step explanation:

Let the amount spent on singles be $x while the amount spent on albums be $y

First day, she downloaded 3 albums and 10 singles that cost $61

Hence;

3y + 10x = 61 ••••••••(ii)

Second day, she downloaded 6 albums and 8 singles for $74

8x + 6y = 74 ••••••••(ii)

We now want to use elimination method to solve both equations

Multiply equation i by 2 and ii by i

20x + 6y = 122

8x + 6y = 74

Subtract ii from i now

12x = 48

x = 48/12

x = 4

Recall;

3y + 10x = 61

substitute for x

3y + 10(4) = 61

3y + 40 = 61

3y = 61-40

3y = 21

y = 21/3

y = 7

An album costs $7 while a single cost $4

10 more than a number c is 3.

Answers

Answer:

10 +c=3

C=3-10

C=-7

.....

Answer:

c = -7

first, make the equation.

10 more than a number c is 3

the variable is c, according to the sentence.

c

"10 more than a number c"

c + 10

"10 more than a number c is 3 "

c + 10 = 3

now that you have your equation, time to solve it.

it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.

for example.

2 + 2 = 4

if you add 1 to both sides of the equation,

2 + 2 + 1 = 4 + 1

5 = 5

this is still true.

Solving the equation.

c + 10 = 3

subtract 10 from both sides of the equation.

c + 10 - 10 = 3 - 10

c = 3 - 10

c = -7

C. It has reflectional symmetry with five lines of symmetry.
D. It has no rotational symmetry.
HELP WILL MARK BRAINLIEST.

Answers

Answer: C. It has reflectional symmetry with five lines of symmetry.

The five lines of symmetry are shown in the diagram below. Each line splits a flower petal in half. Each line also splits the entire flower in half. In other words, reflecting one half of a flower over any given line of symmetry, generates the other half of the flower.

The correct answer is C. The given figure has reflectional symmetry with five lines of symmetry.

Symmetry refers to the property of an object remaining unchanged when certain transformations are applied to it.

A. Point symmetry, also known as rotational symmetry, means that the object looks the same when rotated by a certain angle around a central point. However, a given figure does not have point symmetry since it does not look the same when rotated by any angle around a central point.

B. The statement that the flower has rotational symmetry with an angle of rotation of 120° is incorrect because, as mentioned above, it does not possess rotational symmetry.

C. The flower does have reflectional symmetry with five lines of symmetry. This means that the flower can be divided into five equal parts using five lines of reflectional symmetry, such that each part is a mirror image of the other.

D. The statement that the flower has no rotational symmetry is correct, as mentioned in A and B.

Therefore, the correct answer is C. It has reflectional symmetry with five lines of symmetry.
