The correct option is D.

The variance is based on the deviation about the mean.

The variance is a measure of how spread out a set of data is from its mean value. It measures the average of the squared differences between each data point and the mean of the set.

The formula for variance is given by:

Var(X) = (1/n) * Σ(xᵢ - μ)²

where X is the set of data, n is the number of data points in X, Σ represents the sum of the values from i=1 to n, xᵢ is the i-th data point, and μ is the mean of X.

In the formula, we can see that the deviation from the mean is squared for each data point before taking the average, which means that larger deviations will contribute more to the overall variance.

The variance provides a measure of how much variability there is in the data set relative to the mean, and is often used as a measure of dispersion.

Therefore, the correct option is d.

The triangle ABC

See attachment for the triangle

Also, we have

cos(A) = 12/13

In a right triangle where the acute angles are A and B

This means that

cos(A) = sin(B)

sin(A) = cos(B)

using the above as a guide, we have the following:

sin(B) = cos(A) = 12/13

In conclusion, the present value of your return from this investment, when the stock price is 98, is approximately $1.965.

To find the present value of your return from the investment, we need to calculate the value of the European put option at time t=1/2 and then discount it back to the present value using the nominal annual interest rate of 6 percent compounded monthly.

(a) If S(1/2) = 102:
To calculate the value of the European put option at time t=1/2, we need to determine if it is in-the-money or out-of-the-money.

The strike price is K=100, and since the stock price is greater than the strike price (102 > 100), the put option is out-of-the-money. In this case, the put option has no intrinsic value.

The present value of your return from this investment would be $5, as the put option has no value. There is no profit or loss.

(b) If S(1/2) = 98:
Similar to the previous case, we need to determine if the put option is in-the-money or out-of-the-money. Since the stock price is less than the strike price (98 < 100), the put option is in-the-money.

The intrinsic value of the put option is given by the difference between the strike price and the stock price:

K - S(1/2) = 100 - 98 = 2.

To calculate the present value of your return from this investment, we need to discount the intrinsic value of the put option back to the present value. The nominal annual interest rate of 6 percent compounded monthly translates to a monthly interest rate of 6% / 12 = 0.5%.

Using the formula for the present value of a future cash flow:
Present Value = Intrinsic Value / (1 + Monthly Interest Rate)^(Number of Months)

Number of Months = 1/2 years * 12 months/year = 6 months.

Present Value = 2 / (1 + 0.005)^(6)
Present Value ≈ $1.965.

In conclusion, the present value of your return from this investment, when the stock price is 98, is approximately $1.965.

Answer:

6 trabalhadores

Step-by-step explanation:

Aqui, sabemos que 4 trabalhadores produzem 60 sanduíches em 6 dias.

Agora, queremos saber o número de trabalhadores que produzirão os mesmos 60 sanduíches em 4 dias O que isto significa é que os 4 trabalhadores produzem 10 sanduíches por dia e, portanto, cada um produz 2,5 sanduíches por dia.

Agora temos 4 dias para trabalhar e temos que completar 60 sanduíches. Isso significa que devemos completar 15 sanduíches por dia.

Como cada trabalhador completa 2,5 em um dia, o número de trabalhadores que completam 15 será 15 / 2,5 = 6 trabalhadores

18,995 × 0.82^(6) = $5,774 so he should not sell

if the percentage decrease is 18% then do 100% - 18% which is 82. divide by 100 = 0.82. if it does this for 6 years then do 18,995 × 0.82^(6) because it's 6 years. the number is larger than Manuel's offer therefore he shouldnt sell

1) None of these samples is representative of (or is characteristic of) the entire 10,000 part-time student population.

In the first sample, only students in an organic chemistry class who are also taking first-term calculus are polled. These ten students' experiences with textbooks will be different from those of the other students.

The same applies to the second sample. Only senior citizens who take P.E. classes were polled, and they may have different purchasing patterns than the general population of part-time students.

2) Since these samples are not representative of the entire population, it is not wise to use the results to describe the entire population. As a result, these findings do not reveal anything about the whole population.

3) The first sample (ten students from an organic chemistry class who are also taking first-term calculus) is biased. This sample only contains students who are taking a specific set of courses, and the findings cannot be used to represent the entire population.

In addition, we cannot tell whether the second sample (ten senior citizens who take P.E. classes) is biased. This is because we do not have enough information about the population of senior citizens who take P.E. classes at ABC College.

Answer:

7.62

Step-by-step explanation:

To calculate the distance we can set up a right triangle and use the pythagorean theorem to calculate the distance.

A^2 + B^2 = C^2

Keep in mind that the A and B in this theorem (and my proceeding work) does not correlate to the labels for the points in the problem and are the standard variables used in the theorem.

First lets find the lengths of the sides A and B of our triangle by determing the distance on each axis that seperates the points.

On the x-axis we have

A = 5 - 2

A = 3

The y-axis has

B = 4 - (-3)

B = 7

Plugging these values into the equation from earlier we get:

3^2 + 7^2 = C^2
Where C is the hypotenuse of the right triangle we have created, and the distance between the two points.

9+49 = C^2

sqrt(58) = C

7.615773106 = C

Rounded the the nearest hundredth:

C = 7.62

sinC = 72/97

68 percent of all x values fall between the mean and one standard deviation.

The statement is related to the empirical rule that is often used in statistics. The empirical rule states that for a normal distribution, nearly all data will fall within three standard deviations of the mean. Additionally, the rule mentions that about 68% of the observations will lie within one standard deviation of the mean.

The empirical rule is an observation in statistics that states that for a normal distribution, nearly all data will fall within three standard deviations of the mean. The empirical rule is also called the 68-95-99.7 rule because it states that around 68% of the values fall within one standard deviation of the mean, around 95% of the values fall within two standard deviations of the mean, and nearly all (99.7%) of the values fall within three standard deviations of the mean.

Thus, 68 percent of x values lie between mean and standard deviation(one sided).

If we apply polynomial regression with degree =3 to a task with 3 features, a total of 20 features will be used in this model. This is because for each feature, we generate a polynomial combination with degree up to 3, resulting in a total of (3+3-1) choose 3 = 20 features.

If we apply polynomial regression with degree = 3 to a dataset with 3 features, then the resulting model will use a total of 20 features.

This is because polynomial regression with degree 3 involves creating new features by taking all possible combinations of the original features up to degree 3. In this case, we have 3 original features, so the number of new features created will be:

1 (constant term) + 3 (first-degree terms) + 32/2 (second-degree terms, since there are 3 features and we are taking combinations of 2) + 33*2/6 (third-degree terms, since there are 3 features and we are taking combinations of 3)

= 1 + 3 + 3 + 1 = 8 + 12 = 20

Therefore, the polynomial regression model with degree 3 applied to a dataset with 3 features will use 20 features in total.
