The equation to determine the cost per box, b, can be written as 6b = $132, and solving for b yields b = $22.

Let's denote the cost per box as b. Since Jorge bought a crate with 6 boxes of floor tiles, the total cost of the crate is equal to the cost per box multiplied by the number of boxes: 6b.

According to the given information, the crate of floor tiles cost $132. Therefore, we can write the equation as follows: 6b = $132.

To determine the cost per box, we solve the equation for b. Dividing both sides of the equation by 6, we have b = $132 ÷ 6 = $22.

Hence, the cost per box, b, is $22.

There are 28 ways to choose 6 teams for the playoffs if there are 8 college basketball teams in a certain sub-division.

To determine the number of ways to choose 6 teams for the playoffs out of the 8 college basketball teams in a certain Sub-Division, we can use the combination formula. The formula for combinations is given by

nCr = n! / (r! * (n-r)!),

where n represents the total number of teams and r represents the number of teams to be chosen.

In this case, n = 8 and r = 6.

Plugging in these values, we have

8C6 = 8! / (6! * (8-6)!) = 8! / (6! * 2!) = (8 * 7) / (2 * 1) = 28.

Therefore, there are total 28 ways to choose 6 teams.

We are given the following expression

The subset {[-8x, −5x, 9x]T | x is an arbitrary number, The subset {[x, y, z]T | 3x + 4y = 0, 2x − 8z = 0} their sum will not satisfy the given equations. Therefore, it is not a subspace of R³.

To determine which of the subsets are subspaces of R³, we need to check if they satisfy the three conditions for a subspace: closure under addition, closure under scalar multiplication, and containing the zero vector.

1. The subset {[x, y, z]¹ | 5x – 9y + 6z = 8} satisfies all three conditions and is therefore a subspace of R³.

2. The subset {[x, y, z]T | − 3x – 4y – 2z = 0} also satisfies all three conditions and is a subspace of R³.

3. The subset {[-8x, −5x, 9x]T | x is an arbitrary number} satisfies closure under addition and scalar multiplication, but it does not contain the zero vector [0, 0, 0]T. Therefore, it is not a subspace of R³.

4. The subset {[x, y, z]T | x ≥ 0, y ≥ 0, z ≥ 0} satisfies all three conditions and is a subspace of R³.

5. The subset {[-8x − 6y, −5x – 7y, 9x + 7y]T | x, y are arbitrary numbers} satisfies all three conditions and is a subspace of R³.

6. The subset {[x, x - 3, x − 4] | x is an arbitrary number} satisfies all three conditions and is a subspace of R³.

7. The subset {[x, y, z]T | 3x + 4y = 0, 2x − 8z = 0} does not satisfy closure under addition because if we take two vectors that satisfy the conditions, their sum will not satisfy the given equations. Therefore, it is not a subspace of R³.

The per cent markup for a dozen roses is 166.67%.

Calculate the profit made from selling a dozen roses

24.00 - 9.00 = $15.00

Calculate the markup as a percentage of the cost price

Markup = (Profit / Cost price) × 100%

Markup = (15.00 / 9.00) × 100%

Markup = 166.67%

Therefore, the per cent markup for a dozen roses is 166.67%. This means that for every $9.00 spent on purchasing a dozen roses, the flower stand makes a profit of $15.00, which is 166.67% of the cost price.

To define a default field value in a form or a database, you can use the attribute "default". When you add the "default" attribute to a field, it will automatically assign the specified value to that field if no other value is provided by the user or system.

This can be particularly useful when designing forms or databases that require certain fields to have a value even when the user does not provide one.
For example, in a web form, you might have a "Country" field that requires users to select their country from a dropdown list. By setting a default value for this field, such as "United States," the system ensures that there is always a value associated with that field even if the user does not make a selection.
Similarly, in a database schema, you might have a "DateCreated" field that automatically assigns the current date and time as the default value. This ensures that the date and time are always recorded for each new entry, even if the user does not manually input a value.
In both cases, the "default" attribute allows you to streamline the data collection process and ensure that your forms and databases maintain consistent and complete data. Using default values can also improve the user experience by reducing the amount of input required, making it easier for users to complete forms and submit their data.

The coordinates of the orthocenter of triangle XYZ are (3,2).

To find the coordinates of the orthocenter of triangle XYZ, we need to find the intersection point of the altitudes.

First, we need to find the equations of the three altitudes. An altitude is perpendicular to a side and passes through the opposite vertex.

The equation of the line through X(-1,-4) and perpendicular to YZ is:

y - 4 = (4-(-4))/(7-(-1))(x-7)

y - 4 = 8/8(x-7)

y = -x + 11

The equation of the line through Y(4,7) and perpendicular to XZ is:

y - 7 = (-1/4)*(x-4)

y = (-1/4)x + 8.5

The equation of the line through Z(7,4) and perpendicular to XY is:

y - 4 = (7-(-1))/(-4-(-4))(x-7)

y - 4 = -8/10(x-7)

y = -4/5*x + 36/5

Next, we need to find the intersection points of these lines. We can solve the system of equations:

y = -x + 11

y = (-1/4)x + 8.5

y = -4/5*x + 36/5

Solving this system of equations, we get the coordinates of the orthocenter H:

H(3,2)

x = 28, y = 33 and z = 2,

Given Equations:

3x + 3y − 2z = 14......(1)

x − 6z = 16.......(2)

2x + 5z = −2.......(3)​

Solve equation (2) and (3)

Multiple by 2 in equation (2)

2x − 12z = 32.........(4)

Subtract equation (4) from (3)

According to the Central Limit Theorem, when N (sample size) is sufficiently large, the variance of the distribution of means is one-ninth as large as the original population's variance. The correct answer is A.

In other words, the variance of the sample means is equal to the variance of the original population divided by the sample size. Since N = 9 in this case, the variance of the distribution of means would be one-ninth (1/9) as large as the original population's variance.

The Central Limit Theorem states that as the sample size increases, the distribution of sample means approaches a normal distribution with a mean equal to the population mean and a variance equal to the population variance divided by the sample size.

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.
