The markup is 73.17 percentage , calculated by subtracting the wholesale price ($41) from the retail price ($71) and then dividing the difference by the wholesale price ($41).

The markup is the difference between the wholesale price and the retail price, divided by the wholesale price. To calculate the markup on each club, subtract the wholesale price from the retail price and then divide the difference by the wholesale price. In this example, the wholesale price is $41 and the retail price is $71, so the difference is $30. Dividing $30 by $41 gives a result of 0.7317, which is the markup expressed as a decimal. To express the markup as a percentage, multiply the result by 100, giving a final answer of 73.17%. This means that the retailer is marking up their clubs by 73.17% of the wholesale price.

x = 3 is the answer that gives the equation 4x2 + 12x = 135 a positive solution

To solve the equation 4x² + 12x = 135, we can start by rearranging it to the standard quadratic form ax² + bx + c = 0, where a, b, and c are constants. We get:

4x² + 12x - 135 = 0

Next, we can divide both sides of the equation by 4 to simplify it:

x² + 3x - 33.75 = 0

To solve for x, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

In this case, a = 1, b = 3, and c = -33.75. Substituting these values into the formula, we get:

x = (-3 ± √(3² - 4(1)(-33.75))) / 2(1)

Simplifying the expression inside the square root, we get:

x = (-3 ± √(9 + 135)) / 2

x = (-3 ± √144) / 2

x = (-3 ± 12) / 2

So the two solutions are:

x = -7.5 or x = 3. From the problem statement, we are looking for a positive solution, so we can discard the negative solution x = -7.5.

Therefore, the positive solution to the equation 4x² + 12x = 135 is x = 3.

The probability that a person surveyed went to the concert given they are a fan club member is 2/3 or approximately 0.667.

Probability is a branch of mathematics that deals with the study of random events or phenomena. It is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain.

To find the probability that a person surveyed went to the concert given they are a fan club member, we need to use conditional probability. We can use the following notation:

P(concert | fan club)

This means the probability of going to the concert given that the person is a fan club member.

Let's assume that Jennifer surveyed 100 classmates, and 40 of them are in the Panic Squadron Fan Club and also went to the concert. Also, let's assume that 60 of Jennifer's classmates are in the Panic Squadron Fan Club.

Then, we can use the formula for conditional probability:

P(concert | fan club) = P(concert and fan club) / P(fan club)

Plugging in the values we know, we get:

P(concert | fan club) = 40/60 = 2/3 or approximately 0.667

Therefore, the probability that a person surveyed went to the concert given they are a fan club member is 2/3 or approximately 0.667.

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

Then, we may determine the item's price after the initial 20% discount.

20% of 520$ equals (20/100) * 520$ = 104$, hence the item's new price is 520$ - 104$ = 416$.

After another six months of not selling, the item gets reduced by 60%.

60% of 416$ equals (60/100) * 416$ = 249.60$, therefore the item's ultimate sale price after both markdowns is 416$ - 249.60$ = 166.40$.

Using equations, we can find that the item's selling price after both markdowns is 166.40$.

In an algebraic equation, the equals symbol (=), which represents equality, can be used to connect two quotes. In algebra, an explanation is a declarative statement that establishes the similarity of two formulas. For example, the integers 3x + 5 and 14 are divided by the same letter.

A linear equation can be used to identify the relationship between the texts written on the various sides of a letter. Applications and products can typically be used interchangeably. In this instance, 2x – 4 = 2.

After applying the initial 20% discount, we may determine the item's price as:

20% of 520$ equals (20/100) × 520$ = 104$

Hence the item's new price is 520$ - 104$ = 416$.

After another six months of not selling, the item gets reduced by 60%.

60% of 416$ equals (60/100) × 416$ = 249.60$

Therefore, the item's ultimate sale price after both markdowns is

The critical value of p in a test to determine if a filling system under-fills less than 10% of all boxes, with a significance level of 0.10 and a random sample of size 200, is -1.28.

Assuming that the filling system under-fills with probability p, the null hypothesis is:

H0: p >= 0.10

Ha: p < 0.10 (one-tailed test)

To find the critical value of p, we need to use the inverse cumulative distribution function (ICDF) of the standard normal distribution.

At a significance level of 0.10, the critical value is the value z such that P(Z <= z) = 0.10, where Z is a standard normal random variable. We can find this value using a standard normal table or calculator, or by using the function norm.inv(0.10) in Microsoft Excel, which gives the result -1.28 (rounded to two decimal places).

Since the sample size is large (n = 200), we can use the normal approximation to the binomial distribution to test the null hypothesis. The test statistic is:

z = (x/n - p0) /  √(p0*(1-p0)/n)

where x is the number of boxes that under-fill, n is the sample size, and p0 is the null hypothesis value of the proportion. We want to reject the null hypothesis if the test statistic is less than the critical value of -1.28.

Since we do not have any information about the sample proportion, we can use the null hypothesis value of p0 = 0.10. Then the critical value of the test statistic is:

z_critical = -1.28

Substituting the values into the test statistic formula, we get:

z = (x/200 - 0.10) / √(0.10*(1-0.10)/200)

Simplifying, we get:

z = (x - 20) / 4.24

To reject the null hypothesis at the 0.10 significance level, we need the test statistic z to be less than -1.28. Therefore, we can write the rejection region as:

z < -1.28

Substituting this inequality into the test statistic formula, we get:

(x - 20) / 4.24 < -1.28

Solving for x, we get:

x < 14.5

Therefore, if the number of boxes that under-fill is less than or equal to 14 (out of 200), we reject the null hypothesis at the 0.10 significance level and conclude that there is sufficient evidence to suggest that the filling system under-fills less than 10% of all boxes.

The standard deviation of the boys' marks is 0.33.

Standard deviation is a measure of the amount of variation or dispersion of a set of values from the mean. It is calculated as the square root of the variance. It is the most commonly used measure of spread. It is used to measure the degree of variation from the mean of the data set. It is a measure of the variability of the data. It is usually expressed as a positive number.

The standard deviation of the boys' marks can be calculated by subtracting the mean of the girls' marks from the mean of all 12 marks, and then dividing by the number of boys.

To calculate the mean of the girls' marks, add the three marks together (92 + 80 +71) and divide by 3 (243/3 = 81).

To calculate the mean of all 12 marks, add all 12 marks together (92 + 80 + 71 + …) and divide by 12 (1044/12 = 84).

Therefore the mean of the boys' marks is 84 - 81 = 3.

Now we can calculate the standard deviation of the boys' marks by dividing this value by the number of boys (3/9 = 0.33).

Therefore, the standard deviation of the boys' marks is 0.33.

Standard deviation is a measure of the spread of data around the mean. In this case, the boys' marks had a lower standard deviation than the overall marks, indicating that the boys' marks were more consistent than the girls' marks. This could be due to the fact that there were fewer boys taking the exam, so the boys had a smaller spread of scores than the girls.

Let's work backwards to figure out how many cookies were left after Mrs. Johnson ate 3 cookies:

Before Mrs. Johnson ate the cookies, the class had eaten 5/6 of the cookies, which means that 1/6 of the cookies were left.

Let's call the number of cookies in 1/6 of the batch "x". So the total number of cookies is 6x.

After the class ate 5/6 of the cookies, there were 1/6 of the cookies left, which is x.

Then Mrs. Johnson ate 3/4 of the cookies that were left, which means she ate 3/4*x cookies.

We know that Mrs. Johnson ate 3 cookies, so we can set up the equation: 3 = 3/4*x

Solving for x:

3 = 3/4x

34/3 = x

4 = x

So there were 4 cookies in 1/6 of the batch, which means there were 6 times as many, or 6*4 = 24 cookies in the whole batch.

Therefore, Mrs. Johnson brought 24 cookies to class that day.

Answer: 24 cookies.

Step-by-step explanation:

the answer to the questions is as below

Let's start by using variables to represent the number of cookies that Mrs. Johnson brought to class. Let's say she brought "x" cookies.

We know that the class ate five-sixths of the cookies, which means that there were only one-sixth of the cookies left. This can be represented as:(1/6)x cookies left

We also know that Mrs. Johnson ate three-fourths of the cookies that were left, which is equal to 3 cookies. We can set up an equation to represent this:

(3/4)(1/6)x = 3

Simplifying this equation, we get:

(1/24)x = 1

x = 24

Therefore, Mrs. Johnson brought 24 cookies to class that day.

Sοlving the equatiοns, we can find that, Nicο, Raj and Sandra are cοrrect.

Each term in a linear equatiοn has an expοnent οf 1, and when this algebraic equatiοn is graphed, it always prοduces a straight line. It is called a "linear equatiοn" fοr this reasοn.
