Given statement: Diversification can reduce portfolio risk even when correlations across stock returns equal zero.
Given statement is true.
Because, By diversifying, you spread your investments across various assets, which can help reduce the overall risk of your portfolio. When correlations are zero, it means that the stock returns move independently of each other, further supporting the benefit of diversification in this case.
Diversification can reduce portfolio risk by combining assets with different return patterns, but even when the correlations between the returns are zero, there is still systematic risk (market risk) that cannot be diversified away.
This is because all stocks are subject to macroeconomic factors such as inflation, interest rates, and changes in consumer confidence, which can affect the entire market.
Therefore, even if the correlations across stock returns are zero, diversification cannot completely eliminate portfolio risk.
However, it can still reduce it to a certain extent by spreading the risk across different assets.
The more uncorrelated the assets are in a portfolio, the greater the potential for risk reduction.

A boutique sells blouses and purses. The blouses cost $28 each and the purses cost $39 each. On a certain day the store sells three times as many blouses as purses. If the store sold $1107 worth of these two items on that day, how many of each were sold
Thus, the store sold 9 purses and 27 blouses on that day, and the total revenue from selling these items was $1107.
To solve this problem, we need to use algebraic equations. Let's start by assigning variables to the unknown quantities. Let x be the number of purses sold and y be the number of blouses sold.
From the problem, we know that the blouses cost $28 each and the purses cost $39 each. Therefore, the total revenue from selling x purses and y blouses is given by:
Revenue = 28y + 39x
We also know that the store sold three times as many blouses as purses. Therefore, we can write:
y = 3x
Now we can substitute y = 3x into the revenue equation and solve for x:
1107 = 28y + 39x
1107 = 28(3x) + 39x
1107 = 84x + 39x
1107 = 123x
x = 9
So the store sold 9 purses. To find the number of blouses, we can use the equation y = 3x:
y = 3x = 3(9) = 27
Therefore, the store sold 27 blouses.
In summary, the store sold 9 purses and 27 blouses on that day, and the total revenue from selling these items was $1107.

The area of the composite figure is 84.85 square units
How to find the area of the composite figureThe area of the composite figure is solved by breaking it up and adding together
To find the area of a semicircle of diameter 8, we first need to find the radius of the semicircle, which is half of the diameter:
radius = diameter / 2 = 8 / 2 = 4
area of semicircle = (1/2) * pi * radius^2
= (1/2) * pi * 4^2
= 8 pi
Now, let's find the area of the parallelogram. The area of a parallelogram is given by the formula:
area of parallelogram = base * height
In this case, the base is 10 and the height is 6, so we have:
area of parallelogram = 10 * 6

Students in a high school mathematics class decided that their term project would be a study of the strictness of the parents or guardians of students in the school. Their goal was to estimate the proportion of students in the school who thought of their parents or guardians as “strict”. They do not have time to interview all 1000 students in the school, so they plan to obtain data from a sample of students.
1. Describe the parameter of interest and a statistic the students could use to estimate the parameter.
2. Is the best design for this study a sample survey, an experiment, or an observational study? Explain your reasoning.
3. The students quickly realized that, as there is no definition of “strict”, they could not simply ask a student, “Are your parents or guardians strict?” Write three questions that could provide objective data related to strictness.
4. Describe an appropriate method for obtaining a sample of 100 students, based on your answer in question 1.
Answer:
1. The parameter of interest is the proportion of students in the school who think of their parents or guardians as “strict”. A statistic that the students could use to estimate the parameter is the proportion of students in their sample who think of their parents or guardians as “strict”.
2. The best design for this study is a sample survey. An experiment would involve manipulating the parents' behavior and observing the effect on the students, which is not ethical. An observational study would only observe the behavior without manipulation, but it is not clear what behavior to observe in this case.
3. Here are three questions that could provide objective data related to strictness:
How often are your parents or guardians late to pick you up from school or activities? How often do your parents or guardians check your homework or schoolwork? How often do your parents or guardians allow you to go out with friends on school nights?4. An appropriate method for obtaining a sample of 100 students is random sampling. The students could assign each student in the school a number, and then use a random number generator to select 100 numbers. They could then survey the students corresponding to those numbers. Another method could be stratified sampling, where the students divide the school into groups based on grade level, and then randomly sample a proportionate number of students from each group.
What is an equation of the line that passes through the points (6,4) and (-5,4)?
Hello and Greetings Brainly users.
Answer:The equation of the line that passes through the points (6,4) and (-5,4) is y = 4 , since it is a horizontal straight line through the values of y = 4.Step-by-step explanation:This is an exercise in "Equation of the line that passes through two points". The equation of a line is a mathematical formula used to describe a straight line in a Cartesian plane.
To find the equation of a line that passes through two points, you must first calculate the slope using the formula: m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the given points. Then, the point-slope form of the equation of the line is used to obtain the equation of the line: y - y₁ = m(x - x₁).
By solving this equation, we can obtain the equation of the line that passes through two points. If the slope of the line is zero, as in the case of two points lying on the same horizontal line, then the equation of the line is simply a horizontal line at y = k, where k is the y-coordinate of the points.
As it tells us, we first need to calculate the slope of the line.Applying the following formula:
m = (y₂ - y₁) / (x₂ - x₁)
where m is the slope of the line.
We find that the points are:
x₁ = 6 , y₁ = 4
x₂ = -5 , y₂ = 4
We substitute the data in the formula and solve:
m = (y₂ - y₁) / (x₂ - x₁)
m = (4 - 4)/(-5-6)
m = 0/-11
m = 0
Now, we can use the point-slope form of the equation of the line to obtain the equation of the line:
y - y₁ = m(x - x₁)Where m = 0 and (x₁, y₁) is one of the two given points. We can choose any of the two points, but for this we will choose (6,4).
So, substituting the values we have, we have:
y - 4 = 0(x - 6)
Simplifying, we arrive at:
y - 4 = 0
y = 4
The equation of the line that passes through the points (6,4) and (-5,4) is y = 4 , since it is a horizontal straight line through the values of y = 4.

Answer:
Kailey flipping heads: 3/4 as a fraction, 0.75 as a decimal, and 75% as a percent.
Olivia flipping tails: 9/20 as a fraction, 0.45 as a decimal, and 45% as a percent.
Step-by-step explanation:
Kailey flipped heads 15 times and tails 5 times.
First, find the total amount of times that Kailey flipped the coin.
15+5=20
Kailey flipped the coin 20 times.
Out of those 20 times, she flipped heads 15 times. We can rewrite this as:
[tex]\frac{15}{20}[/tex]
and simplify it:
[tex]\frac{3}{4}[/tex]
3/4 as a decimal is 0.75, and to find the percentage, simply multiply the decimal form by 100.
We can find that 3/4 as a percentage is 75%.
So, the probability of Kailey flipping heads is:
3/4 as a fraction, 0.75 as a decimal, and 75% as a percent.
Olivia flipped heads 11 times and tails 9 times.
Let's find how many times she flipped the coin.
11+9=20
Olivia flipped the coin 20 times.
Out of 20 times, Olivia flipped tails 9 times.
This can be rewritten as:
[tex]\frac{9}{20}[/tex]
This fraction is already in simplest form.
To find what 9/20 is as a decimal, divide 9 by 20. You'll get 0.45.
Now, multiply 0.45 by 100 to find the percent. You'll get 45%.
So, the probability of Olivia flipping tails is:
9/20 as a fraction, 0.45 as a decimal, and 45% as a percent.

b = 3√3
What is the right triangle?A right triangle is a triangle that has a right angle that measures 90 degrees. The hypotenuse, which is the side that faces the right angle, is the longest side. The right triangle's other two sides are referred to as its legs.
1) Cos 45 = 5/c
√2/2 = 5/c
c√2 = 10
c = 10/√2
c = 5√2
2) Tan 30 = b/3
√3/3 = b/3
3√3= 3b
b = 3√3/3
b = 3√3
We have used to concept of the special angles to solve the problem above.
