The break-even point is 1100 products sold. This means that if the store can sell 1100 products, it will be able to cover its costs and make a profit.

What is average ?

The average is a measure of central tendency that is calculated by adding a set of values together and dividing the sum by the number of values. It is also known as the arithmetic mean. It is a way to represent a typical value of a dataset.

The break-even point is the point at which the cost of the products equals the revenue from the sales of the products. To find the break-even point, we need to set the cost function (C(x) = 550 + 3.00x) equal to the revenue function (R(x) = 5.50x) and solve for x.

C(x) = 550 + 3.00x = R(x) = 5.50x

3.00x = 5.50x - 550

0.50x = 550

x = 1100

So the break-even point is 1100 products sold. This means that if the store can sell 1100 products, it will be able to cover its costs and make a profit.

The z score associated with four cups of coffee is -0.19.

To calculate the z score, we use the formula z = (x - μ) / σ,

where x is the value we want to find the z score for, μ is the mean, and σ is the standard deviation.

In this case, x = 4, μ = 4.76, and σ = 4.18. Plugging these values into the formula, we get:
z = (4 - 4.76) / 4.18
z = -0.19
Therefore, the z score associated with four cups of coffee is -0.19.

Hence,  The z-score of -0.182 represents how many standard deviations away 4 cups of coffee is from the mean number of daily cups of coffee for college student respondents in the survey.

Answer:

(1, -3) is a solution to the system of equations ⇒ B

Step-by-step explanation:

Let us solve the system of equations

∵ 3x + 2y = -3 ⇒ (1)

∵ 3x - y = 6 ⇒ (2)

→ Subtract equation (2) from equation (1)

∵ (3x - 3x) + (2y - -y) = (-3 - 6)

∴ (0) + (2y + y) = (-9)

∴ 3y = -9

→ Divide both sides by 3 to find y

∴ y = -3

→ Substitute the value of y in equation (2) to find x

∵ 3x - (-3) = 6

∴ 3x + 3 = 6

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = 6 - 3

∴ 3x = 3

→ Divide both sides by 3 to find x

∴ x = 1

To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right

∵ 3x + 2y = -3

∵ 3(1) + 2(-3) = -3

∴ 3 - 6 = -3

∴ -3 = -3

→ The two sides of the equation are equal

∵ 3x - y = 6

∵ 3(1) - (-3) = 6

∴ 3 + 3 = 6

∴ 6 = 6

→ The two sides of the equation are equal

∴ The solution satisfies the two equations

∴ (1, -3) is a solution to the system

The probability that m balls is P(m balls in first compartment) = (nCm) * ((n-1)^(n-m)) / (n^n).

The total number of possible arrangements of distributing n balls into n compartments is given by n^n. Each ball has n choices for which compartment to fall into, and since there are n balls, we multiply n by itself n times.

Now, let's consider the number of ways m balls can fall into the first compartment. We can choose m balls out of the n balls to go into the first compartment in nCm ways, which is the binomial coefficient.

The remaining (n-m) balls can go into any of the remaining (n-1) compartments in (n-1)^(n-m) ways. Therefore, the probability that m balls will fall into the first compartment is given by:

P(m balls in first compartment) = (nCm) * ((n-1)^(n-m)) / (n^n)

This formula calculates the ratio of favorable outcomes (m balls in the first compartment) to the total number of possible outcomes (all possible arrangements of distributing n balls into n compartments).

A numerical variable is a numerical measure of the outcome of a probability experiment, so its value is determined by chance.

In the mathematical language of measurement theory, the difference between variables is defined as the distance from the measurement point (called the sampling point) to the measurement point. This allows the forward measurement, called the distribution of the variable, to be determined; so the distribution is a measure of the probability of a set of all values ​​of a random variable. The two variables may differ but differ in important respects; so they will be free.

Consider the special cases of random variables and non-continuous random variables, corresponding to how random variables take values ​​in non-continuous problems (for example, as finite sets) or in the range of real numbers. There is another important point, especially in the theory of random processes, where it is important to determine arbitrary sequences or arbitrary functions.

The problem described is option A: "Give an example of a graph that has a relaxed 3-coloring but does not have a proper 3-coloring (where every edge has endpoints of different colors)."

To illustrate this, consider a cycle graph with four vertices. Let's label the vertices as A, B, C, and D. We can assign the colors red, green, and blue to the vertices in the following way:

A -> red

B -> green

C -> red

D -> blue

This is a relaxed 3-coloring because no edge has both endpoints with the same color. However, it is not a proper 3-coloring because vertices A and C are both assigned the color red, and they are connected by an edge.

Regarding option B, proving that it is NP-hard to determine whether a given graph has a relaxed 3-coloring would require a more in-depth analysis and proof based on complexity theory and reduction from known NP-hard problems.

The first derivative of q(x) is q'(x) = (1/(7x^2+3x+7)^(5x^6tan(x))) * [5x^6tan(x)*(7x^2+3x+7)^(5x^6tan(x)-1)*(14x+3) + (7x^2+3x+7)^(5x^6tan(x))*(30x^5tan(x) + 5x^6sec^2(x))].

To find the first derivative of q(x) = ln(7x^2+3x+7)^(5x^6tan(x)), we can use the chain rule and the product rule of differentiation.

Let u = 7x^2+3x+7 and v = 5x^6tan(x). Then, using the chain rule, we have:

q(x) = ln(u^v)

q'(x) = (1/u^v) * d/dx(u^v)

To find d/dx(u^v), we can use the product rule:

d/dx(u^v) = v*u^(v-1)*du/dx + u^v * dv/dx

where du/dx = 14x + 3 is the derivative of u with respect to x, and dv/dx = 30x^5tan(x) + 5x^6sec^2(x) is the derivative of v with respect to x.

Substituting these values into the equation, we get:

d/dx(u^v) = v*u^(v-1)*(14x + 3) + u^v * (30x^5tan(x) + 5x^6sec^2(x))

Substituting this into the expression for q'(x), we get:

q'(x) = (1/u^v) * [v*u^(v-1)*(14x + 3) + u^v * (30x^5tan(x) + 5x^6sec^2(x))]

Finally, we can substitute the expressions for u and v back into this equation to get the first derivative of q(x) in terms of x:

q'(x) = (1/(7x^2+3x+7)^(5x^6tan(x))) * [5x^6tan(x)*(7x^2+3x+7)^(5x^6tan(x)-1)*(14x+3) + (7x^2+3x+7)^(5x^6tan(x))*(30x^5tan(x) + 5x^6sec^2(x))]

The approximate value of ㏒(b) to the nearest hundredth is 1.23.

The other method to write exponents in mathematics is using logarithms. A number's base-based logarithm is equal to some other number. A logarithm performs exponentiation's exact opposite function. 

In Logarithms, ㏒ₐ(b) = ㏒(b)/ ㏒(a)

Given that

The two expressions below have the same value when rounded to the nearest hundredth

=> ㏒₅ (b) = ㏒₉ (48)  

As we know  ㏒ₐ(b) = ㏒(b)/ ㏒(a)

=> ㏒₅ (b) = ㏒(b)/㏒(5)

=> ㏒(b)/㏒(5) = ㏒₉ (48)  

=> ㏒(b) = ㏒₉ (48) ㏒(5)

=> ㏒(b) =  (1.7618)(0.6989)  

=> ㏒(b) = 1.23132202  

=> ㏒(b) = 1.23

There are three possible partitions on the set {1, 2, 3}: Partition 1: { {1}, {2}, {3} } This partition corresponds to the equivalence relation R1 from the previous problem. Partition 2: { {1, 2}, {3} } This partition corresponds to the equivalence relation R2 from the previous problem. Partition 3: { {1, 3}, {2} } This partition corresponds to the equivalence relation R3 from the previous problem.
A partition of a set is a collection of disjoint subsets of the set that together cover the entire set. In other words, each element of the set belongs to exactly one of the subsets. For the set {1, 2, 3}, there are five partitions:
- P1 = {{1}, {2}, {3}}
- P2 = {{1, 2}, {3}}
- P3 = {{1, 3}, {2}}
- P4 = {{2, 3}, {1}}
- P5 = {{1, 2, 3}}
Each of these partitions corresponds to a different equivalence relation on the set {1, 2, 3}.

For example, the partition P1 corresponds to the equivalence relation R1 = {(1, 1), (2, 2), (3, 3)}, which is the identity relation. The partition P2 corresponds to the equivalence relation R2 = {(1, 1), (2, 2), (3, 3), (1, 2), (2, 1)}, which relates 1 and 2 to each other but not to 3. The partition P3 corresponds to the equivalence relation R3 = {(1, 1), (2, 2), (3, 3), (1, 3), (3, 1)}, which relates 1 and 3 to each other but not to 2. The partition P4 corresponds to the equivalence relation R4 = {(1, 1), (2, 2), (3, 3), (2, 3), (3, 2)}, which relates 2 and 3 to each other but not to 1.

Finally, the partition P5 corresponds to the equivalence relation R5 = {(1, 1), (2, 2), (3, 3), (1, 2), (2, 1), (1, 3), (3, 1), (2, 3), (3, 2)}, which relates all of the elements to each other.

The value for the hotspots of the similar triangles ∆ABC and ∆PWR are:

(1). angle B = 68°

(2). PQ = 5cm

(3). BC = 19.5cm

(4). area of ∆PQR = 30cm²

Similar triangles are two triangles that have the same shape, but not necessarily the same size. This means that corresponding angles of the two triangles are equal, and corresponding sides are in proportion.

(1). angle B = 180 - (22 + 90) {sum of interior angles of a triangle}

angle B = 68°

Given that the triangle ∆ABC is similar to the triangle ∆PQR.

(2). PQ/7.5cm = 12cm/18cm

PQ = (12cm × 7.5cm)/18cm {cross multiplication}

PQ = 5cm

(3). 13cm/BC = 12cm/18cm

BC = (13cm × 18cm)/12cm {cross multiplication}

BC = 19.5cm

(4). area of ∆PQR = 1/2 × 12cm × 5cm

area of ∆PQR = 6cm × 5cm

area of ∆PQR = 30cm²

Therefore, the value for the hotspots of the similar triangles ∆ABC and ∆PWR are:
