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 %.

A transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°. What is the value of x?
Answer:
x=116°
Step-by-step explanation:
If a transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°, then the sum of those angles is equal to 180°.
ATQ,
x°+(x-52)°=180°
2x=180°+52
⇒2x=232
⇒x=116°
So, the value of x is 116°

- The value of y varies directly with x. If x= 4,
then y= 32. What is the value of x when y= 176?
Answer: Wouldn't that make it x=44

Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8
Answer:
D
Step-by-step explanation:
Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.
The total number of marbles in the bag could be (d) 8
How to determine the possible total?We have:
Blue proportion = 3/4
This means that the green proportion is
Green proportion = 1 - 3/4
Evaluate
Green proportion = 1/4
Express as ratio
Blue: Green = 3/4 : 1/4
Simplify
Blue: Green = 3 : 1
Add the ratios
Total = 3 + 1
Total = 4
The above means that the total number of marbles in the bag is a multiple of 4
i.e. 4, 8, 12, 16, 20......
Hence, the total number of marbles in the bag could be (d) 8

A company that manufactures dishwashers is testing their latest product to see how long it takes to cool down once a cycle is complete. The function, f(x) = 360 - 15x, represents the cooling cycle, where x is equal to the number of minutes and f(x) is equal to the temperature of the dishwasher after x minutes.
Step-by-step explanation:
Given that the function for the temperature of the dishwasher is
f(x) = 360 - 15x
We are told that x represents the number of minutes it takes to cool down.
with a given/known value of x we can predict the temperature of the dishwasher.
Say x=12 minutes, we can tell what the temperature will be after 12 minutes
by plugin in the value of x=12 in the expressions for the temperature
f(x) = 360 - 15(12)
f(x) = 360 - 180
f(x) = 180
The temperature after 12 minutes will be 180°

1. A hexagon is inscribed in a circle. If the difference between the area of the circle and the area
of the hexagon is 24 m”, use the formula for the area of a sector to approximate the radius
of the circle. Give an exact answer( doesn't have to be rationalized) and round to 2 decimals.
Answer:
The radius, r ≈ 6.55 m
Step-by-step explanation:
The given parameters are;
An inscribed hexagon in a circle
The area of the hexagon = Area of the circle - 24 m²
The formula for the area of the circle = π·r² = π × r²
The area of each of the six equilateral triangle in the hexagon = √3/4 × r²
Where;
r = The radius of the circle
The area of a sector of a circle in which the equilateral triangle is inscribed = 60/360×π·r² = 1/6×π·r² = 1/6 × Area of the circle
Given that the sector of the circle in which one of the six equilateral triangles of the hexagon is inscribed is 1/6 the area of the circle, the difference in area between the equilateral triangle and the sector = 24/6 = 4
Therefore, the difference in the area between the sector of the circle and the area of the equilateral triangle = 4 m²
We then write; 1/6×π·r²- √3/4 × r² = 4
r²·(1/6×π- √3/4) = 4
r² = 4/(1/6 ×π - √3/4) = 48/(2·π -3·√3)
r = √(48/(2·π -3·√3) = 6.55 m to 2 decimal places
The radius, r ≈ 6.55 m.

Calculate the mean of Bryanna's test scores if she has scored 75, 97, and 92 so far this
semester
A 284
o
B
88
c. 75
D
Work Shown:
Add up the values
75+97+92 = 264
Then divide by 3 since there are 3 scores
264/3 = 88
You can write this all as one step
(75+97+92)/3 = 88
So in short, you add the scores and then divide by the number of scores.

4. Which of the following could be the areas of the three squares shown?
Answer:
Option (A)
Step-by-step explanation:
Three squares shown in the figure are formed on the sides of the given right triangle.
By Pythagoras theorem,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
Area of the square on the hypotenuse = Area of the square on the leg 1 + Area of the square on leg 2
Option (A).

True.
Option (B).
45 ≠ 35 + 25
False.
Option (C).
100 ≠ 10 + 10
False.
Option (D).
1200 ≠ 40 + 30
False
Therefore, Option (A) shows the areas of three squares.
Audrey has already scored 53 points,and scored 22 more points with every coin she collects.How many coins does Audrey have to collect to score a total of 97 points
Answer:
Audrey needs to collect 3 more coins.
Step-by-step explanation:
Since she already scored 53 points, we have to find out how many more points she needs to score 97.
So, 97-53=45 points.
The problem says that each coin Audrey collects is worth 22 points. Therefore, 45 divided by 22= 2 remainder 1. However, if she only collects two more coins, Audrey will only have 96 points in total, not 97.
So, add another coin to make 3.
