An equation for Windy Kite's total cost, y, in terms of the number of kites purchased, x, is y = 2x + 20.

An equation for Kites-R-Fun's total cost, y, in terms of the number of kites purchased, x, is y = 4x + 8.

Based on the table, if the Alaskan customer wants to buy 4 kites, Kites-R-Fun charges the least.

If the Alaskan customer wants to buy 10 kites, Windy kites charges the least.

The solution to the system of equations is (6, 32)

In order to write a linear equation to describe this situation, we would a assign variable to the number of kites purchased and the total cost respectively, and then translate the word problem into a linear equation as follows:

Since Wendy charges $2 per kite and a flat rate of $20 for shipping, a linear equation that models the total cost is given by:

y = 2x + 20

When x = 4, the total cost for Windy kites is given by:

y = 2(4) + 20

y = $28.

When x = 7, the total cost for Windy kites is given by:

y = 2(7) + 20

y = $34.

When x = 10, the total cost for Windy kites is given by:

y = 2(10) + 20

y = $40.

For Kites-R-Fun, a linear equation that models the total cost is given by:

y = 4x + 8

When x = 4, the total cost for Kites-R-Fun is given by:

y = 4(4) + 8

y = $24.

When x = 7, the total cost for Kites-R-Fun is given by:

y = 4(7) + 8

y = $36.

When x = 10, the total cost for Kites-R-Fun is given by:

y = 4(10) + 8

y = $48.

The resulting disjoint sets after the operation union({7, 4}) would be: {5, 7, 9, 1, 11, 4, 2, 3, 6, 8, 10}.

The union of two sets A and B is denoted by A ∪ B and is defined as the set of all elements that are either in A or in B or in both. Therefore, the resulting disjoint sets after the operation union({7, 4}) would be:

{5, 7, 9, 1, 11, 4, 2, 3, 6, 8, 10}.

To calculate the union, we can use the following formula:

A ∪ B = {x : x ∈ A or x ∈ B}

Therefore, the union of {7, 4} can be calculated as:

{7, 4} ∪ {7, 4} = {x : x ∈ {7, 4} or x ∈ {7, 4}}

= {7, 4}

The investment compounded periodically will be worth $14,054.52, which is $596.10 more than the investment compounded annually.

To calculate the future value of the investment compounded periodically, we need to use the formula:

FV = P * (1 + (r / n))^(n * t)

where:

P = $6,000 (principal)

r = 6% (annual interest rate)

n = 12 (number of interest periods per year)

t = 17 (number of years)

Plugging in the values, we get:

FV = $6,000 * (1 + (0.06 / 12))^(12 * 17) = $6,000 * (1 + 0.005)^204

FV = $6,000 * (1.005)^204

FV = $14,054.52

So, the investment compounded periodically will be worth $14,054.52 after 17 years.

To calculate the future value of the investment compounded annually, we use the same formula but with n = 1 (one interest period per year):

FV = $6,000 * (1 + 0.06)^17

FV = $6,000 * (1.06)^17

FV = $13,458.42

Answer:

x = 11√2

Step-by-step explanation:

This is a special right triangle. It is marked with a small box in one angle. That is a right angle. So it is a right triangle. It is also marked on two sides with a single hash mark to show that those two sides are the same. This means that the two smaller angles are the same. This is a 45°-45°-90° triangle.

A 45°-45°-90° triangle has a special pattern for knowing the sides of the triangle. One leg is given that it is 11. So the other leg is also 11. Then you could use Pythagorean theorem to find x. But there is a short cut!

Because this is a 45°-45°-90° triangle the hypotenuse (the long side) is:

hypotenuse = leg√2

hypotenuse = 11√2

x = 11√2

This is a handy shortcut, it works for all 45°-45°-90° triangles.

We know that the mean of the data set as computed is obtained from; 345+340+400+625/ 4=  427.5

To obtain the variance of the data.

We now have to take the difference of the values and square it.

The rate of change of the distance among the car and the person at that instant is 110,98 m/s.

To find the average rate of change, we need to divide the change in y (output) by the change in x (input). And visually, all we are doing is calculating the slope of the secant line passing among two points. Finding the average rate of change is particularly useful for determining changes in measurable values like average speed or average velocity.

In this case, consider A as the point where a person is, the intersection (o) and the car from the north form a right triangle. So, based on Pythagoras Theorem:

L^2 = x^2 + y^2

where:

L is the distance between the person and the car.

x is constant since the person does not move.

Now, taking derivatives with respect to time, we will have:

2 * L * dL/dt = 2 * y * dy/dt (1)

where:

x = 15 mts

y = 888

dy/dt = 111 m/s

Now, substitute all the values into the formula:

L^2 = x^2 + y^2

L = √ (15)^2 + (888)^2

L = √ 225 + 788544

L = 888,13 m

So, when we apply to the (1) equation, it will be:

2 * L * dL/dt = 2 * 888 * 111

dL/dt = (888) * 111 / 888,13

dL/dt = 0,99 * 111

dL/dt = 110,98 m/s

Hence, the rate of change of the distance is 110,98 m/s.

Based on the scatterplots provided, the answer would be A. A power model is suitable because the scatterplot of log(weeks) against log(stock price) shows a curved relationship.

In the scatterplots of log(weeks) against log(stock price), we can see that the relationship between the two variables is not linear, but rather appears to be curved. This suggests that a power model may be more appropriate, since this type of model can capture non-linear relationships.

A linear model is not suitable in this case, as the relationship between weeks and stock price does not appear to be linear. While the scatterplot of weeks against log(stock price) shows a strong linear relationship, this plot is not as appropriate for estimating the stock price as the plot of log(weeks) against log(stock price).

An exponential model may also be appropriate for capturing non-linear relationships, but the plot of weeks against log(stock price) does not show a strong linear relationship, so it is less appropriate than the plot of log(weeks) against log(stock price).

There are 363600 ways to arrange 6 people in a row from a group of 10 people, where the bride and the groom are among these 10 people if the bride must be in the picture.

There are 2 possibilities for the position of the bride: either she is first in the row, or she is not first in the row.

If the bride is first in the row, then there are 5 people to choose from for the second person, 4 people to choose from for the third person, and so on, until there is only 1 person left to choose from for the last person in the row. Thus, there are 5! (5 factorial) ways to arrange the 5 people after the bride.

If the bride is not first in the row, then there are 9 people to choose from for the first person, 8 people to choose from for the second person, and so on, until there is only 1 person left to choose from for the last person in the row. Thus, there are 9! (9 factorial) ways to arrange the 9 people before the bride.

Therefore, the total number of ways to arrange the 6 people in a row is 5! + 9! = 720 + 362880 = 363600.

The correct association for each correlation coefficient is as follows:

-0.86: Strong association, 0.52: Moderate association, 0.93: Strong association, -0.66: Moderate association, -0.01: Weak association.

Correlation is a statistical concept that measures the relationship between two or more variables. It is a measure of the degree of association between variables, which can range from -1 to 1. If the correlation between two variables is strong and positive, this means that as one variable increases, the other variable also increases. Conversely, if the correlation is strong and negative, then as one variable increases, the other variable decreases. A correlation of 0 means that there is no association between the variables.

In order to calculate the correlation coefficient, statistical methods such as Pearson's correlation or Spearman's rank correlation are used. The correlation coefficient is a single number that indicates the strength and direction of the relationship between the variables. It is important to note that correlation does not imply causation, and it is possible for two variables to be highly correlated without any causal relationship between them.

The correlation coefficient represents the strength of the relationship between two variables. A positive correlation coefficient implies that the two variables have a positive link, whereas a negative correlation value shows that the two variables have a negative association. The size of the correlation coefficient shows its strength: a coefficient of 0.86 suggests a high relationship between the two variables, whilst a coefficient of 0.52 indicates a moderate relationship. A coefficient of 0.93 suggests a stronger relationship, whilst a value of -0.66 shows a somewhat negative relationship between the two variables. Finally, a correlation value of -0.01 shows that the two variables have a very weak relationship.
