Step-by-step explanation:

The break even point is x = 4  for cost C = 24x + 80 and Revenue R = 44x.

Cost is the amount of money spent by a business to produce or provide goods or services. It excludes the profit margin markup. Cost is the sum of money spent on making a thing or product, as seen from the seller's perspective.

Cost is defined as the total of real input costs and imputed costs associated with owner-supplied inputs.

The entire money derived from the sale of products or services pertaining to a business's core operations is referred to as revenue. Because it appears at the top of the income statement, revenue, which is also known as gross sales, is sometimes referred to as the "top line." A company's overall profits or profit are referred to as income, or net income.

The break-even threshold is reached when overall costs and total revenues are equal, leaving your small firm with no net benefit or loss. In other words, you've achieved the point in manufacturing when the income from a product matches the cost of manufacture.

At break even point cost equals revenue,

Therefore,

Cost = Revenue

⇒ 24x +80 = 44x

⇒ 20x = 80

⇒ x = 4.

The break even point is x = 4 .

Option B is Correct. Determine the number of solutions to a quadratic equation using the discriminant, b^2-4ac. We utilise the condition as follows for a quadratic equation of the form ax^2+bx+c=0.a=0. There is only one solution to the equation if b^2 - 4ac = 0.

Keeping in mind that a, b, and c are the coefficients of your quadratic in standard form, the discriminant is calculated using the formula b squared minus 4ac. It reveals how many possible answers there are to a quadratic problem.

There are two solutions if the discriminant is bigger than zero. The square root's input (i.e., its contents), which is the phrase b^2 = 4ac, is known as the "discriminant" because using its value, you may "discriminate" between (i.e., be able to distinguish between) the different solution types.

Answer:

2.5n is larger than or equal to (> with the line under) 5.25

Step-by-step explanation:

let's say the number is "n"

2 1/2 of n is at least 5 1/4

at least is a synonym to larger than or equal to, which is the fourth symbol, >_ with the line underneath.

The inequality 2.5x ≥ 5.25 represents the statement "Two and a half times a number is at least five and one-fourth"

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality symbol "≥" represents "at least," indicating that the result should be greater than or equal to 5.25.

The inequality that represents this statement is:

2.5x ≥ 5.25

Where x is the number,

This means that if we multiply a number by 2.5, the result should be greater than or equal to 5.25. In other words, 2.5x should be greater than or equal to 5.25.

No, X or y-axis scale does not have to always start at zero. In a line chart, it's OK to start the axis at a number other than zero

A line that is used to take or mark measurements is known as an axis in mathematics. Two crucial axes of the coordinate plane are the x and y axes. A horizontal number line is the x-axis, while a vertical number line is the y-axis. The coordinate plane is created by the perpendicular intersection of these two axes.

Given,

No, X or y-axis scale does not have to always start at zero.

A line chart encodes data using location (x, y coordinates), whereas a bar chart represents data using length.

When comparing the means of two populations using hypothesis testing, the choice between the pooled t-test and the Mann-Whitney test depends on the nature of the populations' distributions. Let's explore  both scenarios:

a. The correct answer is D. Use the pooled t-test. When the distributions of the variable are normal and have the same shape, the pooled t-test is appropriate for comparing the means of the two populations.

The pooled t-test assumes normality, and when the distributions are normal, it provides slightly more statistical power compared to the Mann-Whitney test. The assumption of equal standard deviations between the populations is also necessary for using the pooled t-test.

b. The correct answer is B. Use the Mann-Whitney test since the distributions of the variable are not normal and have the same shape.

The Mann-Whitney test is a nonparametric test that does not require the assumption of normality. It is suitable for comparing the means of two populations when the distributions are not normal.

As the question states that the distributions have the same shape, the Mann-Whitney test can be used to test for a difference in the population means.

The pooled t-test assumes normality, and since the distributions are not normal, it is not appropriate to use in this case.

The Mann-Whitney test is a nonparametric test that does not require normality assumptions, and can be used to compare the medians of two populations based on independent samples.

the number of students who use none of the three browsers is the difference between the total number of students in the class (85) and the number of students who use at least one of the three browsers: 85 - 100 = 10.

From the given information, we know that 20 students use only Chrome, 15 students use only Safari, and 15 students use only Internet Explorer. Since none of the students use all three browsers, the number of students using only one browser is 20 + 15 + 15 = 50.

Now, let's calculate the number of students who use multiple browsers. The total number of students using Chrome is 45, and 20 of them use only Chrome. Therefore, the number of students using Chrome along with other browsers is 45 - 20 = 25. Similarly, the number of students using Safari or Internet Explorer along with other browsers is also 25.

Substitution is the replacing the variables in an algebraic expression with their numerical values. It involves substituting the value of any one of the variables.

How to determine this

When an adult ticket costs  £7.50

A child ticket costs  £3.50.

Let x represent the number of adult tickets

And let y represent the number of child tickets

When Brooke sold tickets for her show

i.e x + y = 100 ----  (1)

From the equation, by making y the subject of the formula

y = 100 - x ----  (2)

7.50x + 3.50y = 590  ---- (3)

By substituting equation 2 into 3

7.50x + 3.50(100 - x) = 590

Open bracket

7.50x + 350 - 3.50x = 590

Collect like terms

7.50x - 3.50x = 590 - 350

4x = 240

Divides through by 4

4x/4 = 240/4

x = 240/4

x = 60

When y = 100 - x

x = 60

So, y = 100 - 60

y = 40

Therefore, the amount she sold for adult tickets to child tickets is 60 tickets to 40 tickets respectively

Answer:

We rotate the point counterclockwise by an angle θ = tan⁻¹ (y/x)

Step-by-step explanation:

If we have the point (x, y), its reflection along the x-axis (x,-y). The reflection of the point (x, -y) along the y - axis is (-x, -y). So, the angle between the initial point (x, y) and the final point (-x, -y) is θ = tan⁻¹ [(-y - y)/(- x -x)] = tan⁻¹ [(-2y/(-2x)] =  tan⁻¹(y/x).

So, the point (x, y) is rotated counterclockwise by an angle of  θ = tan⁻¹ (y/x) to perform both reflections.

The 99% confidence level produces the most comprehensive interval due to the increase in critical value.

99%, because, as the level of confidence increases, zc increases.

The level of confidence is the probability that actual value will fall in the confidence interval determined using sample statistics. As the probability increases, the area (middle part) under the curve expands, which results in increasing the critical value(zc) that determines the acceptance region.

The increase in the critical value results in increasing the margin of error, which defines the confidence interval's spread from the mean value of the distribution.

Hence, the 99% confidence level produces the most comprehensive interval due to the increase in critical value.

We can see that the statement is not always true for any vectors u and v in V3.

The statement is not always true.

The cross product of vectors u and v in V3 is a vector that is orthogonal to both u and v. That is,

u x v ⊥ u and u x v ⊥ v

However, this does not necessarily mean that (u x v) * u = 0 for all u and v in V3.

For example, let u = <1, 0, 0> and v = <0, 1, 0>. Then,

u x v = <0, 0, 1>

(u x v) * u = <0, 0, 1> * <1, 0, 0> = 0

So in this case, the statement is true. However, consider the vectors u = <1, 1, 0> and v = <0, 1, 1>. Then,

u x v = <1, -1, 1>

(u x v) * u = <1, -1, 1> * <1, 1, 0> = 0

So in this case, the statement is also true. However, if we take the vector u = <1, 0, 0> and v = <0, 0, 1>, then

u x v = <0, 1, 0>

(u x v) * u = <0, 1, 0> * <1, 0, 0> = 0

So in this case, the statement is true as well.

However, if we take the vector u = <1, 1, 1> and v = <0, 1, 0>, then

u x v = <1, 0, 1>

(u x v) * u = <1, 0, 1> * <1, 1, 1> = 2

So in this case, the statement is not true.

Limit does not exist at x=3.

Step-by-step explanation:

Using the given graph, we need to check whether the limit exists or not.

From the given graph it is clear that

1. When x approaches to 3 from the left side then function approaches to -1.

2. When x approaches to 3 from the right side then function approaches to -3.

3. When x=3, the value of function is 7.

So, we conclude that

\(LHL=\lim\limits_{x\to 3^-}f(x)=-1\)

\(RHL=\lim\limits_{x\to 3^+}f(x)=-3\)

\(\lim\limits_{x\to 3}f(x)=7\)

Since \(LHL\neq RHL\), therefore the limit does not exist at x=3.
