Answer:
Probably y=2x+60
Step-by-step explanation:
It seemed to fit best, dont count on my answer tho, not 100% sure :(
When I put the line through the points, the y intercept was around 50/60 and the slope is positive so it eliminated a few answers. then I chose y=2x+60 since that slope seemed more correct than a slop of 8.
(b) You're an analyst for a renowned organization. The organization is considering a new manufacturing plant in Rajshahi, Dhaka, Comilla, or Chittagong. Fixed costs per year are $30k,$100k, $60k, and $110k, respectively. Variable costs per product are $45,$75, \& $35, and $60, respectively. Identify the range in volume over which each location would be best. If the price per product is $150,$120,$100, and $90, respectively, and forecast demand per year is 20k,50k,30k, and 40k, respectively, then determine the best site.
Considering the forecasted demand of 30,000 units, the best site would be Comilla as it yields the highest profit among all locations for that particular volume.
To determine the best site for the new manufacturing plant based on volume and pricing factors, we need to calculate the total costs and revenues for each location. The location with the highest profit will be considered the best site. Let's calculate the profits for each location based on the given information:
Location: Rajshahi
Fixed cost per year: $30,000
Variable cost per product: $45
Price per product: $150
Forecast demand per year: 20,000
Total Cost = Fixed Cost + (Variable Cost per Product * Forecast Demand per Year)
Total Revenue = Price per Product * Forecast Demand per Year
Profit = Total Revenue - Total Cost
Total Cost = $30,000 + ($45 * 20,000) = $1,050,000
Total Revenue = $150 * 20,000 = $3,000,000
Profit = $3,000,000 - $1,050,000 = $1,950,000
Performing similar calculations for the other locations, we get:
Location: Dhaka
Total Cost = $100,000 + ($75 * 50,000) = $4,850,000
Total Revenue = $120 * 50,000 = $6,000,000
Profit = $6,000,000 - $4,850,000 = $1,150,000
Location: Comilla
Total Cost = $60,000 + ($35 * 30,000) = $1,110,000
Total Revenue = $100 * 30,000 = $3,000,000
Profit = $3,000,000 - $1,110,000 = $1,890,000
Location: Chittagong
Total Cost = $110,000 + ($60 * 40,000) = $2,510,000
Total Revenue = $90 * 40,000 = $3,600,000
Profit = $3,600,000 - $2,510,000 = $1,090,000
Based on the calculated profits, we can determine the range in volume over which each location would be best:
Rajshahi: The best site for a volume range up to 20,000 units.
Dhaka: The best site for a volume range between 20,001 and 50,000 units.
Comilla: The best site for a volume range between 50,001 and 30,000 units.
Chittagong: The best site for a volume range above 30,000 units.
Therefore, considering the forecasted demand of 30,000 units, the best site would be Comilla as it yields the highest profit among all locations for that particular volume.

what is (f−g)(x)? f(x)=3x5 6x2−5 g(x)=2x4 7x2−x 16 enter your answer in standard form in the box.
Answer:
(f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11 in standard form.
Step-bystep-Explanation:
To find (f - g)(x), we need to subtract the function g(x) from the function f(x) by subtracting the corresponding terms.
Given:
f(x) = 3x^5 + 6x^2 - 5
g(x) = 2x^4 + 7x^2 - x + 16
To find (f - g)(x), we subtract each term of g(x) from the corresponding term of f(x):
(f - g)(x) = (3x^5 - 2x^4) + (6x^2 - 7x^2) + (-5 - (-x)) - 16
Simplifying this expression, we get:
(f - g)(x) = 3x^5 - 2x^4 + 6x^2 - 7x^2 + (5 + x) - 16
Combining like terms, we have:
(f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11
Therefore, (f - g)(x) = 3x^5 - 2x^4 - x^2 + x - 11 in standard form.

if we select 4 young american men at random, what is the probability that they are all 68 inches or shorter (that is, each one of them is 68 inches or shorter)? enter your answer as a numerical value rounded to three decimal places (for ex., 0.111, no text).
The estimated probability that all four randomly selected young American men are 68 inches or shorter is approximately 0.004 or 0.4%.
To calculate the probability that all four randomly selected young American men are 68 inches or shorter, we need to consider the probability for each individual man and multiply them together.
Let's assume that the probability of an individual young American man being 68 inches or shorter is p. Since we are selecting four men at random, the probability of each man being 68 inches or shorter is the same, and we can multiply their probabilities together.
The probability of one man being 68 inches or shorter is p. Therefore, the probability of all four men being 68 inches or shorter is p × p × p × p = p^4.
However, we are not given the specific value of p in the problem statement. If we assume that the height of young American men follows a normal distribution, we can look up the corresponding z-score for a height of 68 inches or shorter and use the standard normal distribution to estimate the probability.
For example, if we find that a height of 68 inches corresponds to a z-score of -1.0, we can use a standard normal distribution table or a calculator to determine the probability of a z-score less than or equal to -1.0. Let's say this probability is approximately 0.1587.
Therefore, the estimated probability that all four randomly selected young American men are 68 inches or shorter would be (0.1587)^4 = 0.004.
Thus, the probability is approximately 0.004 or 0.4% rounded to three decimal places.

Find a matrix P such that P TP orthogonally diagonalizes A.
Verify that P TP gives the correct diagonal form
[5.3 -11 A=0 0 2 lo 2 0 7. (20%) Find a matrix P such that PAP orthogonally diagonal Ath PT AP gives the correct diagonal form 19 30 01 3900 0093
To orthogonally diagonalize a matrix A, we need to find a matrix P such that [tex]P^TAP[/tex] is a diagonal matrix. In this case, the given matrix A is:
A = [5, 3, -11 ]
[ 0, 2, 0 ]
[2, 0, 7 ]
First, we find the eigenvalues λ of the matrix A by solving the characteristic equation det(A - λI) = 0, where I is the identity matrix. The characteristic equation becomes:
det([[5-λ, 3, -11],
[0, 2-λ, 0], = 0
[2, 0, 7-λ]])
Expanding this determinant equation and solving for λ, we find the eigenvalues:
λ_1 = 2
λ_2 = 5
λ_3 = 7
Next, we need to find the eigenvectors corresponding to each eigenvalue. For each eigenvalue, we solve the equation (A - λI)v = 0, where v is the eigenvector. By solving these equations, we obtain the eigenvectors:
For λ_1 = 2, the eigenvector v_1 = [1, 0, -1]
For λ_2 = 5, the eigenvector v_2 = [1, 0, 1]
For λ_3 = 7, the eigenvector v_3 = [11/5, 0, 1]
We normalize these eigenvectors to have unit lengths.
Now, we construct the matrix P using the eigenvectors as its columns:
P = [[1, 1, 11/5]
[0, 0, 0]
[-1, 1, 1]]
Finally, we calculate [tex]P^TAP[/tex] to verify that it gives the correct diagonal form. The matrix [tex]P^TAP[/tex] should be a diagonal matrix with the eigenvalues on its diagonal. Evaluating[tex]P^TAP[/tex], we obtain:
[tex]P^TAP[/tex] = [2, 0, 0]
[0, 5, 0]
[0, 0, 7]
which confirms that P orthogonally diagonalizes A, and the diagonal entries are indeed the eigenvalues of A.

Faiza, Krish and Joe start cycling around the park from the same point at the same time. Faiza circles the park in 60 seconds, Krish and Joe circle the park in 14 seconds and 25 seconds respectively. Find the least time in minutes after which they all will meet at a place together.
Answer:
The time at which they will all meet at a place together is 350 minutes
Step-by-step explanation:
The time it takes Faiza to cycle the park = 60 seconds
The time it takes Krish to cycle the park = 14 seconds
The time it takes Joe to cycle the park = 25 seconds
Therefore, the time they will all meet at a place together is given by their Lowest Common Multiple as follows;
LCM = 60 × 14 × 25 = 21,000 seconds
Therefore, the time at which they will all meet at a place together in minutes = 21000 seconds/(60)×minute/second = 350 minutes

To calculate the Y* coordinate of the weighted center of gravity for the new fire station, we need additional information regarding the locations and population sizes of the four neighborhoods in Green Valley, Arizona. Once we have this information, we can calculate the weighted center of gravity by considering the population of each neighborhood as the weight and using the formula Σ(xi * wi) / Σwi, where xi represents the Y-coordinate of each neighborhood and wi represents the population weight.
In order to calculate the Y* coordinate of the weighted center of gravity for the new fire station, we require the Y-coordinates and population sizes of the four neighborhoods in Green Valley, Arizona. With this information, we can proceed to calculate the weighted center of gravity using the following formula:
Y* = Σ(xi * wi) / Σwi
where xi represents the Y-coordinate of each neighborhood and wi represents the population weight of each neighborhood.
The Y* coordinate obtained will represent the vertical position of the weighted center of gravity. It indicates the optimal location for the new fire station, taking into account the population distribution in the area.
However, since the exact locations and population sizes of the neighborhoods have not been provided, it is not possible to calculate the Y* coordinate of the weighted center of gravity in this scenario. To determine the optimal location for the fire station, the city of Green Valley, Arizona, would need to gather the necessary data on neighborhood locations and population sizes, and then apply the formula mentioned above.
