PLEASE HELP ME ASAP !! A small cheese pizza costs you $2.50 to make and its box costs $0.25. A large cheese pizza costs $4.15 and its box costs $0.50. You sell a small cheese pizza for $9.00 and a large for $14.25. Give a few different combinations of boxes and pizza that you will have to sell to have a profit the first year of business? Second year? (not including taxes)

Answers

Answer 1

Answer:

To make a profit in the first year of business, the company needs to sell enough small and large cheese pizzas with their respective boxes to generate more revenue than the cost of making and packaging the pizzas.

Similarly, to make a profit in the second year, the company needs to sell enough small and large cheese pizzas with their respective boxes to generate more revenue than the cost of making and packaging the pizzas. Different combinations of pizzas and boxes can be used to achieve a profit, as long as the total revenue generated is greater than the total cost incurred.

Step-by-step explanation:

To find the profit for each combination of boxes and pizzas, we need to subtract the total cost from the total revenue. Let's call the number of small cheese pizzas sold S, the number of large cheese pizzas sold L, the number of small boxes used for the small pizzas B1, and the number of large boxes used for the large pizzas B2. Then, the profit for each year can be calculated as follows:

First year profit:

Total revenue = 9S + 14.25L

Total cost = 2.5S + 0.25B1 + 4.15L + 0.5B2

Profit = Total revenue - Total cost

Profit = 9S + 14.25L - 2.5S - 0.25B1 - 4.15L - 0.5B2

Profit = 6.5S + 10.1L - 0.25B1 - 0.5B2

Second year profit:

Total revenue = 9S + 14.25L

Total cost = 2.5S + 0.25B1 + 4.15L + 0.5B2

Profit = Total revenue - Total cost

Profit = 9S + 14.25L - 2.5S - 0.25B1 - 4.15L - 0.5B2

Profit = 6.5S + 10.1L - 0.25B1 - 0.5B2

To have a profit for the first year, the profit equation should be greater than 0. We can find different combinations of S, L, B1, and B2 that will satisfy this condition. Here are a few examples:

Sell 10 small cheese pizzas and 5 large cheese pizzas. Use 20 small boxes and 10 large boxes.

Profit = 6.5(10) + 10.1(5) - 0.25(20) - 0.5(10) = $55.75

Sell 20 small cheese pizzas and 10 large cheese pizzas. Use 40 small boxes and 20 large boxes.

Profit = 6.5(20) + 10.1(10) - 0.25(40) - 0.5(20) = $111.50

Sell 30 small cheese pizzas and 15 large cheese pizzas. Use 60 small boxes and 30 large boxes.

Profit = 6.5(30) + 10.1(15) - 0.25(60) - 0.5(30) = $167.25

Similarly, to have a profit for the second year, the profit equation should be greater than 0. We can find different combinations of S, L, B1, and B2 that will satisfy this condition. Here are a few examples:

Sell 15 small cheese pizzas and 7 large cheese pizzas. Use 30 small boxes and 15 large boxes.

Profit = 6.5(15) + 10.1(7) - 0.25(30) - 0.5(15) = $89.65

Sell 25 small cheese pizzas and 12 large cheese pizzas. Use 50 small boxes and 24 large boxes.

Profit = 6.5(25) + 10.1(12) - 0.25(50) - 0.5(24) = $166.65

Sell 35 small cheese pizzas and 17 large cheese pizzas. Use 70 small boxes and 34 large boxes.

Calculate the probability that the next home in the community will sell for less than $350,000.00 but more than $250,000.00. Label the mean, standard deviation, and indicate the appropriate area on the included graph of a normal distribution.

Answers

On the graph of the normal distribution, we would label the mean as 276,000, the standard deviation as 32,000, and shade the appropriate area to represent the probabilities we calculated.

To calculate the probabilities, we will use the normal distribution function on the calculator. The parameters we will enter are the mean, standard deviation, and the values we are interested in finding the probability for.

a. To find the probability that the next home will sell for less than $220,000.00, we need to calculate the z-score first.
z-score = (220,000 - 276,000) / 32,000 = -1.75

Using the calculator, we will enter the function:

normdist(-1.75, 0, 1, TRUE)

where -1.75 is the z-score, 0 is the mean, 1 is the standard deviation, and TRUE indicates that we want to find the area to the left of the z-score.

The result is 0.0401, which means there is a 4.01% chance that the next home will sell for less than $220,000.00.

b. To find the probability that the next home will sell for less than $350,000.00 but more than $250,000.00, we need to calculate the z-scores for both values.

z-score for $350,000 = (350,000 - 276,000) / 32,000 = 2.31
z-score for $250,000 = (250,000 - 276,000) / 32,000 = -0.81

Using the calculator, we will enter the function:

normdist(2.31, 0, 1, TRUE) - normdist(-0.81, 0, 1, TRUE)

where 2.31 and -0.81 are the z-scores for $350,000 and $250,000 respectively, 0 is the mean, 1 is the standard deviation, and TRUE indicates that we want to find the area to the left of the z-scores.

The result is 0.3758, which means there is a 37.58% chance that the next home will sell for less than $350,000.00 but more than $250,000.00.

Find the critical value t Subscript c for the confidence level c=0.98 and sample size n=24

Answers

The critical value t Subscript c for a confidence level of 0.98 and sample size of 24 is 2.500.

To find the critical value t Subscript c for the confidence level c=0.98 and sample size n=24, we can use a t-distribution table or calculator.

Since we have a sample size of n=24, we have n-1 = 23 degrees of freedom. Using a t-distribution table or calculator with 23 degrees of freedom and a confidence level of 0.98, we get

t Subscript c = 2.500

Therefore, the critical value t Subscript c for the confidence level c=0.98 and sample size n=24 is 2.500. This means that if we calculate the t-value from our sample data and it is greater than or less than 2.500 in absolute value, we can reject the null hypothesis at the 0.02 level of significance.

Answers

The perimeter of the triangle is 56 inches.

The Pythagorean theorem is a fundamental concept in mathematics that relates to the sides of a right triangle. It states that the square of the length of the hypotenuse (the longest side) of a right triangle is equal to the sum of the squares of the lengths of the other two sides

We can use the Pythagorean theorem to find the length of the hypotenuse, which is the missing side of the right triangle:

[tex]c^2 = a^2 + b^2[/tex]

[tex]c^2 = 7^2 + 24^2[/tex]

[tex]c^2 = 625[/tex]

c = 25

So the length of the hypotenuse is 25 inches. The perimeter of the triangle is the sum of the lengths of its three sides:

P = 7 + 24 + 25

P = 56

Therefore, the perimeter of the triangle is 56 inches.

The function which describes the zeroes of the graph of f(x) = 3x6 + 30x5 +75x42 is 5 with multiplicity 2 and 3 with multiplicity 4, the correct option is B.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The function  f(x) = 3x6 + 30x5 +75x42

Now,

We can factorize f(x) = 3x6 + 30x5 +75x4 by taking out the common factor of 3x4:

f(x) = 3x4(x2 + 10x + 25)

Then we can factorize the quadratic expression inside the parentheses by finding two numbers that multiply to 25 and add to 10. These numbers are 5 and 5, so we have:

f(x) = 3x4(x + 5)(x + 5)

To find the zeroes, we set f(x) equal to zero and solve for x:

0 = 3x4(x + 5)(x + 5)

This equation has two solutions: x = 0 and x = -5. However, x = 0 is a zero of multiplicity 4, because it makes x4 equal to zero four times. Similarly, x = -5 is a zero of multiplicity 2, because it makes (x + 5) equal to zero twice.

Therefore, by the function the answer will be 5 with multiplicity 2 and 3 with multiplicity 4

(Chapter 12) For any vectors u and v in V3, (u + v) X v= (u X v)

Answers

After substitution, we get (u + v) X v = u X v + 0, which simplifies to (u + v) X v = u X v thus proving that (u + v) X v = u X v for any vectors u and v in V3.

To prove the statement (u + v) X v = u X v for any vectors u and v in V3, we will use the properties of the cross product. First, we know that the cross product is distributive over addition, meaning that (u + v) X v = u X v + v X v.

However, we also know that the cross product of a vector with itself is zero, since the angle between the two vectors is zero degrees. Therefore, v X v = 0.

Substituting this into the previous equation gives us (u + v) X v = u X v + 0, which simplifies to (u + v) X v = u X v.

Therefore, we have proven that (u + v) X v = u X v for any vectors u and v in V3.

You are given a z-test statistic of -0.99, and you want to find the corresponding P-value. The P-value represents the probability of observing a test statistic as extreme as, or more extreme than, the one calculated, given that the null hypothesis is true.

Step 1: Identify the z-test statistic
The z-test statistic is given as -0.99.

Step 2: Find the cumulative probability associated with the z-test statistic
Using a z-table or a statistical software, you can find the cumulative probability associated with a z-test statistic of -0.99.

Step 3: Determine the P-value
The cumulative probability you find in Step 2 is equivalent to the P-value since the alternative hypothesis is of the form p < p₀, and the P-value is the area under the z curve to the left of the calculated value of the test statistic.

P-value = (z curve area to the left of -0.99)

After finding the cumulative probability in a z-table or using a statistical software for a z-score of -0.99, you get:

P-value = 0.1611 (rounded to four decimal places)

If x is a nontrivial solution of Ax=0​, then every entry in x is nonzero. T/F?

Answers

The statement "If x is a nontrivial solution of Ax=0​, then every entry in x is nonzero" is False.

A nontrivial solution means that there is at least one nonzero entry in x. However, it doesn't imply that every entry in x must be nonzero. It's possible to have a mixture of nonzero and zero entries in a nontrivial solution.

If x is a nontrivial solution of Ax=0, it means that x is a nonzero vector in the null space of A. This implies that A x = 0, which means that the linear combination of the columns of A given by x results in the zero vector.

However, this does not necessarily mean that every entry in x is nonzero. For example, consider the matrix A given by:

A = [1 0 1;

0 1 1;

1 1 2]

The null space of A contains the vector x = [-1; 1; 1], which is a nontrivial solution of Ax = 0. However, this vector has one entry that is zero and two entries that are nonzero.

g in a simple undirected graph with 8 vertices and 27 edges, how many vertices can have degree 7?

Answers

In a simple undirected graph with 8 vertices and 27 edges, the maximum degree for a vertex is 7, since a vertex can connect to all other vertices. To determine the number of vertices that can have degree 7, we will consider the properties of simple graphs and the relationship between vertices, edges, and degrees.

In a simple graph, there are no self-loops or multiple edges between the same pair of vertices. Therefore, the maximum number of edges in a simple graph with n vertices can be calculated using the formula:


[tex]Max edges = n(n-1)/2\\[/tex]

For our graph with 8 vertices, the maximum number of edges is:

Max edges = 8(8-1)/2 = 8(7)/2 = 28

Since our graph has 27 edges, it is almost a complete graph (which would have 28 edges). To figure out how many vertices can have a degree of 7, we can examine the degrees of other vertices.

If we have one vertex with degree 7, the remaining 7 vertices will be fully connected to each other, forming a complete subgraph with 7 vertices. The number of edges in this subgraph is:

Edges = 7(7-1)/2 = 7(6)/2 = 21

The total number of edges in the graph, including the vertex with degree 7, is 21 + 7 = 28. Since our graph has 27 edges, we need to remove one edge from this configuration. We can remove one edge between two of the vertices that are not the vertex with degree 7. By doing this, we maintain the degree 7 for the first vertex while reducing the degrees of two other vertices to 6.

Therefore, in a simple undirected graph with 8 vertices and 27 edges, 1 vertex can have a degree of 7.

The total cost for 13 rides is 46 $.

Amount to be paid as entry fee = 20 $

Amount to be paid in each ride = 2 $

Therefore, total cost for 13 rides, P = 20 + (2 x 13)

P = 46 $

Total cost for r rides, P' = (20 + 2r) $

What is the yield on a corporate bond with a $1000
face value purchased at a discount price of $850, if
it pays 8% fixed interest for the duration of the
bond?
yield = [?] %
Give your answer as a percent rounded to the nearest
hundredth.

Answers

The yield on a corporate bond is A = 9.14 %

Given data ,

Face value of the bond (FV) = $1000

Purchase price of the bond = $850

Fixed interest rate = 8%

The annual interest payment (I) can be calculated as a percentage of the face value:

I = (Fixed interest rate / 100) * FV

Substituting the given values:

I = (8 / 100) x 1000 = $80

The yield (Y) can be calculated as:

Y = (Annual interest payment / Purchase price) * 100

Substituting the calculated values:

Y = (80 / 850) x 100 = 9.41%

Hence , the yield on the corporate bond is 9.41%

6. an economics researcher wants to estimate the mean number of hours worked by all grocery store employees in the county. how many employees must be included in the sample to be 95% confident that the sample mean is within 1.5 hours of the population mean? a previous study showed that the population standard deviation is 7.9. the critical value for a level of confidence of 95% is 1.96.

Answers

The number of employees that must be included in the sample to be 95% confident that the sample mean is within 1.5 hours of the population mean is 107 employees.

To estimate the mean number of hours worked by all grocery store employees in the county with 95% confidence and a margin of error of 1.5 hours, we can use the sample size formula:

n = (Z * σ / E)²

where:
- n is the required sample size
- Z is the critical value (1.96 for a 95% level of confidence)
- σ is the population standard deviation (7.9 from the previous study)
- E is the margin of error (1.5 hours)

Plugging in the given values:

n = (1.96 * 7.9 / 1.5)²

n ≈ 106.56

Since you cannot have a fraction of an employee, you need to round up to the nearest whole number. Therefore, the researcher must include 107 employees in the sample to be 95% confident that the sample mean is within 1.5 hours of the population mean.

can someone help with question 19

Answers

Answer:

48. 192

Step-by-step explanation:

In order to get from 3/4 to 3/16, one way would be to divide by 4. Another way is to multiply 3/4 by 1/4.

You can test whether multiplying by 4 works by multiplying 3/4 by 4 and 3 by 4.

When 3/4 is multiplied by 4, it would equal 12/3 which will simplify to 3. This can be done again with 3*4=12.

So the answer would be 12*4 = 48 and 48*4 = 192.
