Which of the following values are solutions to the inequality 5x+5≥−9?

An increase in an asset's expected return relative to that of an alternative asset, holding everything else constant, (option a) increases the quantity demanded of the asset.

Given,

Asset's expected return;-

The weight of each asset is multiplied by its projected return to determine the expected return. The total predicted return for your portfolio may then be calculated by adding the figures for each investment. Hence, the equation Asset 1 Weight x Expected Return = Expected Portfolio Return Plus (Asset 2 Weight x Expected Return)

Hence,

An increase in an asset's expected return relative to that of an alternative asset, holding everything else constant, (option a) increases the quantity demanded of the asset.

The given statement that Adverse selection occurs because of asymmetric information is true . Because it happens when one party have no idea about other party .

Adverse Selection:

Adverse selection generally refers to the situation in which the seller has information that the buyer does not have or, conversely, knows about aspects of the product's quality. In other words, it is a case of misusing asymmetric information. Information asymmetry, also known as information impairment, occurs when one party to a transaction has more important knowledge than the other party.

For example, corporate managers may be more willing to issue stock if they know that the stock is overvalued relative to its true value. Buyers may suffer losses by purchasing overvalued stocks. In the used car market, sellers can learn about vehicle defects and charge buyers extra fees without disclosing the problem.

A common consequence of negative selection is that consumers lack information from sellers and manufacturers, increasing costs and creating market asymmetries.

Selling price of the hair clip with markup 200 percent and cost of $0.50 is $1.50.

As given in the question,

Cost to manufacture a hair clip is equal to $0.50

Markup percent = 200%

Let 'x' be the selling price of the hair clip.

Formula used for markup percent is:

Markup percent =( Selling price - cost ) / cost

Substitute the value we get,

⇒ 200% =( x- 0.50) / 0.50

⇒ 200/100 =( x- 0.50) / 0.50

⇒ x - 0.50 =2 × 0.50

⇒ x =  $1.50

Therefore, the selling price of the hair clip with given markup percent and cost is $1.50.

What are the linear equations in two variables?

A linear equation in two variables is one that is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e. a and b, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are two-variable linear equations.

Let the cost of one hot dog be 'x' dollars and the cost of one water bottle be 'y' dollars.

By using the given data, we can prepare the equations

             4x + 6y = 22 ------(I)

             8x + 3y = 35------(II)

Multiplying equation(I) and taking subtraction, we get

               9y =  9

                 y = 9/9

                 y = 1

Put y = 1 in equation (I), and we get

          4x + 6 = 22

          4x = 22 - 6

          4x = 16

            x = 4

Hence, the cost of one hot dog would be $4 and the cost of one water bottle would be $1.

Joint Distribution of x and y is 25.

Joint Distribution is based on joint probability, which can be simply defined as the probability of two events happening together.

We know the formula for joint distribution

F(x,y) = P(X ≤ x and Y ≤ y) = ∑∑p(xi,yi)

Here x is the number of aces and y is the number of kings in a poker hand.

That means x can take values from 0 to 4 and y can take values from 0 to 4.

∴ F(x,y) = P(X ≤ 4 and Y ≤ 4)

⇒ F(x,y) = p(0,0) + p(0,1) + p(0,2) + p(0,3) + p(0,4) + p(1,0) + p(1,1) + p(1,2) + p(1,3) + p(1,4) + p(2,0) + p(2,1) + p(2,2) + p(2,3) + p(2,4) + p(3,0) + p(3,1) + p(3,2) + p(3,3) + p(3,4) + p(4,0) + p(4,1) + p(4,2) + p(4,3) + p(4,4).

To find all these values we will construct a table as follows;

P(x,y)           Y=0      Y=1         Y=2      Y=3    Y=4

X=0              0          1/4          1/2        3/4       1      

X=1               1/4        1/2        3/4         1        5/4

X=2             1/2         3/4         1            5/4     3/2

X=3             3/4          1          5/4         3/2      7/4      

X=4               1          5/4         3/2       7/4       2

Now the joint distribution will become,

F(x,y) = 0 + 1/4 + 1/2 + 3/4 + 1 + 1/4 + 1/2 + 3/4 +1  + 5/4 + 1/2 + 3/4 + 1 + 5/4 + 3/2 + 3/4 + 1 + 5/4 + 3/2 + 7/4 + 1 + 5/4 + 3/2 + 7/4 + 2

F(x,y) = 25

The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

So having at lest 1 girl out of 3 children is the same as saying that all 3 children are not boys.

The probability that all 3 children are boys would be

chance that child 1 is a boy * chance that child 2 is a boy * chance that child 3 is a boy = 0.5 * 0.5 * 0.5 = 0.125

"When the relationship between two quantities is such that if we increase one, the other will also rise, and if we decrease one, the other quantity will also drop, then the two quantities are in a direct proportion," according to the definition of direct proportion. For instance, suppose there are two numbers, x and y, where x is the number of candies and y is the total amount of money spent. If we purchase more candy, we will be required to pay more, and if we purchase fewer candies, we will be required to pay less. This means that x and y are directly proportional to one another in this situation. The symbol for it is x y. Direct variation is another name for direct proportion.

So,

In the given question, we have:

y as 8 and x as 16;

So,

In order to find the proportional value, we have to divide the x quantity by the y quantity.

So, after dividing we get:
