Step-by-step explanation:

If an investor bought a put option on ABC common stock for $53 per contract with an exercise price of $558 and the stock price at expiration is $46, the net profit would be $459.

To calculate the net profit on a put option, we need to consider the initial cost of the option and the difference between the exercise price and the stock price at expiration.

Given:

Put option purchase price: $53 per contract

Exercise price: $558

Stock price at expiration: $46

Since the stock price at expiration ($46) is lower than the exercise price ($558) in the case of a put option, the option is in the money. The option holder has the right to sell the stock at a higher price than its market value.

To calculate the net profit, we need to consider the initial cost and the difference in stock price:

Net Profit = [(Exercise Price - Stock Price) - Option Cost] * Number of Contracts

In this case:

Net Profit = [(558 - 46) - 53] * 1 (assuming one contract)

= (512 - 53) * 1

= $459

Therefore, the net profit from this put option, assuming one contract, would be $459.

Conclusion: If the stock price at expiration is $46 and an investor purchased a put option on ABC common stock for $53 per contract with an exercise price of $558, the net profit would be $459. This implies that the investor would have a positive return on their investment, as the option is in the money.

The distance of the student from the foot of the tower is 25.63m the nearest 1/2 is 25.5m.

Given that From the top of a tower 14m high

The angle of depression of a student is 32°

we can use trigonometry to find the distance from the foot of the tower to the student:

tan(32°) = opposite/adjacent = 14/distance

Rearranging this equation gives:

distance = 14/tan(32°)

= 25.63m

Therefore, the distance of the student from the foot of the tower is approximately 25.63m nearest 1/2, this is 25.5m.

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Step-by-step explanation:

Answer:

Ummm What???

Step-by-step explanation:

To solve for C₁, C₂, and C₃ such that g(x) = 0 on the interval (-∞, ∞), we need to find the coefficients that make the linear combination of the functions f₁(x), f₂(x), and f₃(x) equal to zero.

We have the following functions:

f₁(x) = x

f₂(x) = x²

f₃(x) = 2x - 7x²

And we need to find C₁, C₂, and C₃ such that:

g(x) = C₁f₁(x) + C₂f₂(x) + C₃f₃(x) = 0

Substituting the given functions, we have:

C₁x + C₂x² + C₃(2x - 7x²) = 0

To solve for C₁, C₂, and C₃, we can equate the coefficients of like terms. Let's match the coefficients of x, x², and the constant term separately:

For the coefficient of x:

C₁ + 2C₃ = 0     ...(1)

For the coefficient of x²:

C₂ - 7C₃ = 0      ...(2)

For the constant term:

0 = 0              ...(3)

From equation (3), we can see that the constant term doesn't impose any constraints on the coefficients.

Now, we solve equations (1) and (2) simultaneously to find the values of C₁, C₂, and C₃:

From equation (2), we have:

C₂ = 7C₃

Substituting this into equation (1), we get:

C₁ + 2C₃ = 0

Since we have two variables and one equation, we can't determine unique values for C₁, C₂, and C₃. Instead, we can express them in terms of a single parameter, let's say C₃:

C₁ = -2C₃

C₂ = 7C₃

So, the solution for C₁, C₂, and C₃ in terms of C₃ is:

C₁ = -2C₃

C₂ = 7C₃

C₃ = C₃

In summary, the solution for C₁, C₂, and C₃ such that g(x) = 0 on the interval (-∞, ∞) is given by:

C₁ = -2C₃

C₂ = 7C₃

C₃ = C₃

Note that the parameter C₃ can take any real value, including zero, resulting in the trivial solution (0, 0, 0).

Step-by-step explanation:

Given:

Kendra charges $8.00 for two puzzles and a piece of candy.

She charges $4.50 for one puzzle and a piece of candy.

To find:

The cost of each puzzle.

Solution:

Let x be the cost of a puzzle and y be the cost of piece of candy.

Kendra charges $8.00 for two puzzles and a piece of candy.

\(2x+y=8\)               ...(i)

She charges $4.50 for one puzzle and a piece of candy.

\(x+y=4.50\)             ...(ii)

Subtracting (ii) from (i), we get

\(2x+y-(x+y)=8-4.50\)

\(2x+y-x-y=3.50\)

\(x=3.50\)

The cost of puzzle is $3.50. Therefore, the correct option is A.

The total number of red marbles in the vase are 10.

A ratio is described as a comparison between two amounts with the same unit to determine the amount of 1 quantity is contained in the other. Ratios are divided into two sorts.

The first is a part-to-part ratio, and the second is a part-to-whole ratio. The part-to-part ratio expresses the relationship between 2 separate entities or groupings.

Now, according to the question;

Let 'x' be the red marbles in the vase.

Let 'y' be the orange marbles in the vase.

The total number of marbles in the vase are 60

x  + y = 60 (equation 1)

The ratio of red marbles to orange ones is 1:5.

Thus, x/y = 1/5

cross multiplying;

5x = y

or y = 5x

substitute the value of y in equation 1;

x  + y = 60 (equation 1)

x  + 5x = 60

6x = 60

x = 10  (red marbles)

Thus, the number of red marbles in the vase are 10.

The probability that in a randomly selected year, the number of lightning strikes is 4, is 0.098.

What is Poisson distribution?

The Poisson distribution refers to a probability distribution expressing the probability of a specific number of events occurring in a fixed interval of time, if these events occur with a known constant mean rate and independent of the occurrence of the last event.

P(E) = Probability of occurrence of E in a fixed interval 'x', with constant mean = \(\frac{e^{-mean}. mean^{x}}{x!}\)

Step-by-step explanation:

Let A be the number of lightning strikes in a year at the top of particular mountain. Here, A follows Poisson distribution with mean = 2.1.

According to the question, x = 4, mean = 2.1

Thus, putting it in the formula for Poisson distribution, we get:

P(A) = \(\frac{e^{-2.1}(2.1)^{4} }{4!}\) = \(\frac{0.122(19.44)}{24}\) = 0.098

=> P(A) = 0.098

Hence, the probability that in a randomly selected year, the number of lightning strikes is 4, is 0.098.
