Yes, a weighted analysis table can be a helpful tool in determining which business function is the most critical to an organization. By assigning weights to different factors or criteria that contribute to the success of each business function.
This can be especially useful when an organization is deciding where to allocate resources or focus efforts. The weighted analysis table helps to ensure that decisions are based on a thorough and systematic analysis of all relevant factors, rather than subjective opinions or assumptions.
A weighted analysis table can indeed be useful in determining the most critical business function to an organization. Here's a step-by-step explanation of how to use a weighted analysis table for this purpose:
1. Identify the business functions: List all the key business functions within the organization, such as marketing, finance, human resources, operations, and IT.
2. Determine criteria for evaluation: Define the criteria that will be used to evaluate the importance of each business function. Examples could be revenue generation, cost reduction, customer satisfaction, or employee productivity.
3. Assign weights to criteria: Assign a weight to each criterion based on its relative importance to the organization's success. The sum of the weights should equal 100%.
4. Evaluate business functions against criteria: Rate each business function on how well it meets each criterion on a scale (e.g., 1-5 or 1-10). Be objective and consistent when assigning these ratings.
5. Calculate weighted scores: Multiply the rating for each criterion by its respective weight, and then sum up the resulting values to get the weighted score for each business function.
6. Rank the business functions: Rank the business functions based on their weighted scores, from highest to lowest. The business function with the highest weighted score will be considered the most critical to the organization.
By following these steps, a weighted analysis table can help you effectively identify the most critical business function within your organization, allowing you to allocate resources and prioritize efforts accordingly.

A car panel is spray painted by a machine, and the technicians are particularly interested in the thickness of the resulting paint layer. Suppose that the random variable X measures the thickness of the paint in millimeters at a randomly chosen point on a randomly chosen car panel, and that X takes values between 0.125 and 0.5, with a probability density function of:
f(x)=A(0.5 - (x - 0.25)2) for 0.125x0.5 and f(x)=0 elsewhere.
a) Find the value of A and sketch the probability density function
b)Construct and sketch the cumulative distribution function
c)What is the probability that the paint thickness at a particular point is less than 0.2mm?
The probability that the paint thickness at a particular point is less than 0.2mm is approximately 0.14.
a) To find the value of A, we need to use the fact that the total area under the probability density function must be equal to 1:
∫0.5 0.125 f(x) dx = 1
Using the given formula for f(x), we get:
∫0.5 0.125 A(0.5 - (x - 0.25)2) dx = 1
Expanding the square inside the integral, we get:
∫0.5 0.125 A(0.5 - x2 + 0.5x - 0.0625) dx = 1
Simplifying and integrating, we get:
A(0.5x - 1/3 x3 + 0.5(1/2)x2 - 0.0625x)∣∣0.125^0.5 = 1
Substituting the limits of integration and simplifying, we get:
A(1/48) = 1
Therefore, A = 48.
The probability density function can be sketched by plotting the function f(x) against x for values of x between 0.125 and 0.5. It will look like a bell-shaped curve with its maximum value at x = 0.25 and decreasing to 0 at x = 0.125 and x = 0.5.
b) The cumulative distribution function (CDF) is defined as:
F(x) = P(X ≤ x) = ∫(-∞)x f(t) dt
To construct the CDF, we need to integrate the probability density function from 0.125 to x:
F(x) = ∫x 0.125 f(t) dt
Using the formula for f(x), we get:
F(x) = 48∫x 0.125 (0.5 - (t - 0.25)2) dt
Simplifying the integral and integrating, we get:
F(x) = 16(x - 0.25) + 3/2(x - 0.25)3 - 1/16(x - 0.25)4
The cumulative distribution function can be sketched by plotting F(x) against x for values of x between 0.125 and 0.5. It will start at 0 when x = 0.125 and approach 1 when x = 0.5, and will be an increasing curve with a maximum slope at x = 0.25.
c) To find the probability that the paint thickness at a particular point is less than 0.2mm, we need to evaluate the cumulative distribution function at x = 0.2:
P(X ≤ 0.2) = F(0.2) = 16(0.2 - 0.25) + 3/2(0.2 - 0.25)3 - 1/16(0.2 - 0.25)4
P(X ≤ 0.2) ≈ 0.14
Therefore, the probability that the paint thickness at a particular point is less than 0.2mm is approximately 0.14.

Find any relative extrema. f(x,y) = x³ – 12xy + 8y³ A. f(2,1)= - 8, relative minimum B. f(1,2)= 9, relative minimum c. f(1,2)= 9, relative maximum D. f(2,1)= - 8, relative maximum
The correct answer is A. f(2,1) = -8, relative minimum and B. f(1,2) = 9, relative minimum.
To find relative extrema of the function f(x,y) = x³ - 12xy + 8y³, we first find the partial derivatives f_x and f_y:
f_x = 3x² - 12y
f_y = -12x + 24y²
Set both partial derivatives equal to 0 to find critical points:
3x² - 12y = 0 => x² = 4y
-12x + 24y² = 0 => x = 2y²
Solving these equations simultaneously, we get the critical points (2,1) and (1,2). To determine if these points are relative minima or maxima, we use the second derivative test. Compute the second partial derivatives:
f_xx = 6x
f_yy = 48y
f_xy = f_yx = -12
Evaluate the discriminant D = (f_xx * f_yy) - (f_xy * f_yx) at each critical point:
D(2,1) = (12 * 48) - (-12 * -12) = 576 - 144 = 432 > 0, and f_xx(2,1) = 12 > 0, so it's a relative minimum with value f(2,1) = -8.
D(1,2) = (6 * 96) - (-12 * -12) = 576 - 144 = 432 > 0, and f_xx(1,2) = 6 > 0, so it's a relative minimum with value f(1,2) = 9.

A local retailer has determined that the number x of PortaBoy game systems sold in a week is related to the price p in dollars of each system. 20 game systems were sold when the price was $120. When the systems went on sale the following week, 50 systems were sold at $75 a piece.
A. Find a linear function which fits this data. Use the weekly sales x as the independent variable and the price p as the dependent variable.
(b) Find a suitable applied domain:
(c) If the retailer wants to sell 80 PortaBoys next week, what should the price be?
A. To find a linear function, we need to determine the slope and y-intercept of the equation. Using the two data points given:
Slope = (50-20)/($75-$120) = 30/(-45) = -2/3
Using point-slope form, we can find the equation:
y - 50 = (-2/3)(x - 75)
y = (-2/3)x + 100
Therefore, the linear function is: p = (-2/3)x + 100, where x is the weekly sales and p is the price in dollars.
B. The suitable applied domain for this function is the range of weekly sales that the retailer expects to encounter. In this case, it could be any value greater than 0 and less than or equal to 50 (since that was the highest weekly sales number given in the data).
C. To find the price the retailer should set to sell 80 PortaBoys next week, we can plug in x = 80 into the linear function:
p = (-2/3)(80) + 100
p = $46.67
Therefore, the retailer should set the price at $46.67 to sell 80 PortaBoys next week.
A. To find the linear function, we'll use the given data points: (x1, p1) = (20, 120) and (x2, p2) = (50, 75). The general form of a linear function is p = m*x + b, where m is the slope and b is the y-intercept.
First, we find the slope (m):
m = (p2 - p1) / (x2 - x1)
m = (75 - 120) / (50 - 20)
m = (-45) / 30
m = -1.5
Now, we'll use one of the data points to find the y-intercept (b). Let's use (20, 120):
120 = -1.5 * 20 + b
120 = -30 + b
b = 150
So, the linear function fitting this data is: p(x) = -1.5x + 150
B. A suitable applied domain for this function would be x ∈ [0, ∞), meaning the number of PortaBoy game systems sold should be greater than or equal to 0.
C. To find the price at which the retailer should sell the systems to sell 80 PortaBoys, we'll plug x = 80 into the function:
p(80) = -1.5 * 80 + 150
p(80) = -120 + 150
p(80) = 30
The retailer should set the price at $30 per system to sell 80 PortaBoys next week.

16 children are standing in line to receive a total of 100 100 pieces of candy, with each child guaranteed to receive at least 1 1 piece. at least how many pieces must the first child in line receive to ensure that he or she has the greatest number after all 100 100 pieces are distributed?
To ensure that the first child in line has the greatest number of candy after all 100 pieces are distributed, they must receive as many pieces as possible. We know that each child is guaranteed at least one piece of candy, which means that the 16 children will receive a minimum of 16 pieces altogether.
To find the maximum number of pieces the first child can receive, we can start by assuming that each of the remaining 15 children receive only one piece of candy. This would leave a total of 85 pieces for the first child to receive.
However, we want to maximize the number of pieces the first child can receive while still ensuring that each of the other children receives at least one piece. We can achieve this by giving the second child 2 pieces of candy, the third child 3 pieces, and so on, until we get to the 15th child who receives 15 pieces. This leaves a total of 40 pieces for the first child to receive, which is the maximum amount they can receive while still guaranteeing that each of the other children receives at least one piece.
Therefore, the first child must receive at least 40 pieces of candy to ensure that they have the greatest number after all 100 pieces are distributed.

1. In this problem we show that the function
f(x,y)=6x?y2x+y2
does not have a limit as (x,y)?(0,0).
(a) Suppose that we consider (x,y)?(0,0) along the curve y=2x1/2. Find the limit in this case:
lim(x,2x1/2)?(0,0)6x?y2x+y2=
(b) Now consider (x,y)?(0,0) along the curve y=3x1/2. Find the limit in this case:
lim(x,3x1/2)?(0,0)6x?y2x+y2=
(c) Note that the results from (a) and (b) indicate that f has no limit as (x,y)?(0,0) (be sure you can explain why!).
To show this more generally, consider (x,y)?(0,0) along the curve y=mx1/2, for arbitrary m. Find the limit in this case:
lim(x,mx1/2)?(0,0)6x?y2x+y2=
2. What value of c makes the following function continuous at (0,0)?
f(x,y)={x+y4+2,c,(x,y)?(0,0)(x,y)=(0,0)
1. (a) The limit as (x,y) approaches (0,0) along this curve is 6/5.
(b) The limit as (x,y) approaches (0,0) along this curve is 3/5.
(c) The limit as (x,y) approaches (0,0) along this curve is 6.
2. The value of c that makes the function f(x,y) continuous at (0,0) is c=0.
1. (a) Along the curve y=2x1/2, we have y2 = 4x. Substituting this into the expression for f(x,y), we get:
f(x,y) = 6x/(4x + x) = 6x/5x = 6/5
Therefore, the limit as (x,y) approaches (0,0) along this curve is 6/5.
(b) Along the curve y=3x1/2, we have y2 = 9x. Substituting this into the expression for f(x,y), we get:
f(x,y) = 6x/(9x + x) = 6x/10x = 3/5
Therefore, the limit as (x,y) approaches (0,0) along this curve is 3/5.
(c) Along the curve y=mx1/2, we have y2 = m2x. Substituting this into the expression for f(x,y), we get:
f(x,y) = 6x/(m2x + x) = 6x/(m2 + 1)x
If m ≠ 0, then as x approaches 0, the denominator approaches m2 + 1, and the numerator approaches 0. Therefore, the limit is 0.
If m = 0, then the curve y=mx1/2 reduces to the x-axis. Along this curve, we have y = 0, so y2 = 0. Substituting this into the expression for f(x,y), we get:
f(x,y) = 6x/(0 + x) = 6
Therefore, the limit as (x,y) approaches (0,0) along this curve is 6.
Since the limit depends on the value of m, and there are different limits along different curves passing through (0,0), we conclude that the limit of f(x,y) does not exist as (x,y) approaches (0,0).
2. To make the function f(x,y) continuous at (0,0), we need to find the value of c such that the limit of f(x,y) as (x,y) approaches (0,0) along any path equals c. Specifically, we need the limit to exist and be equal to c along the x-axis and the y-axis.
Along the x-axis, we have y = 0, so f(x,0) = x. Therefore, the limit of f(x,y) as (x,y) approaches (0,0) along the x-axis is 0 + 0 + 2c = c.
Along the y-axis, we have x = 0, so f(0,y) = y4 + 2. Therefore, the limit of f(x,y) as (x,y) approaches (0,0) along the y-axis is 0 + 0 + c = c.
To make the function continuous at (0,0), we need both limits to be equal to c. Therefore, we must have:
c = c + 2c
2c = c
c = 0
Therefore, the value of c that makes the function f(x,y) continuous at (0,0) is c=0.

Find the volume of the solid of revolution obtained by rotatingthe finite region bounded by the curves y = x − x3and y= x − x2 about the y-axis
The volume of the solid of revolution is (31/30)π.
How to find the volume of a solid of revolution?To find the volume of the solid of revolution, we need to use the method of cylindrical shells. We will integrate over the height of the region, which is from y=0 to y=1.
First, let's find the points of intersection between the curves:
[tex]x - x^3\\ = x - x^2x^3 - x^2\\ = 0x^2(x-1) \\= 0x=0, x=1[/tex]
So the region we need to rotate is bound by the curves x=0, x=1, y=x-x^3 and y=x-x^2.
Next, we need to express the curves in terms of x and y as follows:
[tex]x = y + y^3\\x = y + y^2[/tex]
To use the method of cylindrical shells, we need to express the radius of each shell as a function of y. The radius of each shell is the distance from the y-axis to the curve at a given height y.
The distance from the y-axis to the curve [tex]x = y + y^3[/tex] is simply [tex]x = y + y^3.[/tex]Therefore, the radius of each shell is r = y + y^3.
The distance from the y-axis to the curve [tex]x = y + y^2 is x = y + y^2.[/tex]Therefore, the radius of each shell is[tex]r = y + y^2.[/tex]
The volume of each shell is given by the formula V = 2πrhΔy, where h is the height of the shell (which is simply Δy) and Δy is the thickness of each shell.
Thus, the total volume of the solid of revolution is given by the integral:
[tex]V = ∫[0,1] 2π(y+y^3)(y+y^2) dy\\V = 2π ∫[0,1] (y^4 + 2y^3 + y^2) dy\\V = 2π [(1/5)y^5 + (1/2)y^4 + (1/3)y^3] [0,1]\\V = 2π [(1/5) + (1/2) + (1/3)]V = (31/30)π[/tex]
Therefore, the volume of the solid of revolution is (31/30)π.

a. y = sin(7x)/tan(3x)
To differentiate this function, we can use the quotient rule, which states that if we have a function in the form f(x) = g(x)/h(x), where g(x) and h(x) are differentiable functions, the derivative of f(x) is given by:
f'(x) = (g'(x) * h(x) - g(x) * h'(x)) / (h(x))²
In this case, g(x) = sin(7x) and h(x) = tan(3x). Let's differentiate both g(x) and h(x) first:
g'(x) = d/dx [sin(7x)] = 7 * cos(7x)
h'(x) = d/dx [tan(3x)] = 3 * sec²(3x)
Now we can substitute these derivatives into the quotient rule formula:
y' = [(7 * cos(7x) * tan(3x)) - (sin(7x) * 3 * sec²(3x))] / (tan(3x))²
Simplifying further, we get:
y' = [7 * cos(7x) * tan(3x) - 3 * sin(7x) * sec²3x)] / [tan²(3x)]
b. y = [tex]\pi^{(3x^2-7)[/tex] + x/(x²+9) + cos⁻¹(32x+1)
To differentiate this function, we can use the sum and chain rules. Let's differentiate each term separately:
For the first term, y₁ = [tex]\pi^{(3x^2-7)[/tex]:
y₁' = d/dx [[tex]\pi^{(3x^2-7)[/tex]]
Using the chain rule, the derivative is:
y₁' = (ln(π) * [tex]\pi^{(3x^2-7)[/tex]) * (6x)
For the second term, y₂ = x/(x²+9):
y₂' = d/dx [x/(x²+9)]
Using the quotient rule, the derivative is:
y₂' = [(1 * (x²+9)) - (x * 2x)] / (x²+9)²
Simplifying further, we get:
y₂' = (9 - x²) / (x²+9)²
For the third term, y₃ = cos⁻¹(32x+1):
y₃' = d/dx [cos⁻¹(32x+1)]
Using the chain rule, the derivative is:
y₃' = -32 / sqrt(1 - (32x+1)²)
Now, we can add all the derivatives together to find the derivative of the function:
y' = y₁' + y₂' + y₃'
y' = (ln(π) * [tex]\pi^{(3x^2-7)[/tex])) * (6x) + (9 - x²) / (x²+9)² - 32 / sqrt(1 - (32x+1)²)

The given identity sin(0) + sin(o) = 2 sin(2*0 - o) * cos(o) is false when checked using complex exponentials and Euler's formula.
To check the given identity using complex exponentials, we'll make use of Euler's formula, which states:
e^(ix) = cos(x) + i*sin(x)
Let's rewrite the given identity in terms of complex exponentials:

Now, we'll apply Euler's formula:
(1/2i)(e^(i0) - e^(-i0)) + (1/2i)(e^(io) - e^(-io)) = 2(1/2i)(e^(i(2*0 - o)) - e^(-i(2*0 - o))) * (1/2)(e^(io) + e^(-io))

Set, in a triangle ABC, points B 'and C such that B' divides side CA in the ratio 4: 4 from C, and C divides side AB in the ratio 3: 5 from A. Denote the point of intersection between BB 'and CC with T. The vectors AB and AC in the triangle are non-parallel and therefore form a base in the plane. Determine the coordinates of the vector AT in this base.
To determine the coordinates of vector AT in this base, we first need to find the coordinates of points B' and C.
Let's start by finding the coordinates of B'. Since B' divides side CA in the ratio 4:4 from C, we can use the following formula to find its coordinates:
B' = (4C + 4A)/8
Simplifying this expression, we get:
B' = (C + A)/2
Similarly, we can find the coordinates of C using the fact that it divides AB in the ratio 3:5 from A:
C = (3A + 5B)/8
Now, we can use these coordinates to find the equation of lines BB' and CC.
The equation of line BB' can be found using the point-slope form:
BB': y - yB = (yB' - yB)/(xB' - xB) * (x - xB)
Substituting the coordinates of B and B', we get:
BB': y - 0 = (yB'/2)/(xB'/2) * (x - 1)
Simplifying this expression, we get:
BB': y = (yB'/xB') * x - yB'/2
Similarly, we can find the equation of line CC:
CC: y = (yC'/xC') * x - yC'/2
Now, we can find the coordinates of point T by solving the system of equations formed by the equations of lines BB' and CC:
(yB'/xB') * x - yB'/2 = (yC'/xC') * x - yC'/2
Simplifying this expression, we get:
x = (yC' - yB') / ((yC'/xC') - (yB'/xB'))
Substituting this value of x into the equation of line BB', we get:
y = (yB'/xB') * ((yC' - yB') / ((yC'/xC') - (yB'/xB'))) - yB'/2
Simplifying this expression, we get:
y = ((yB' * xC') - (yC' * xB')) / (2 * (xC' - xB'))
Now, we can find the coordinates of point T:
T = (x, y)
Substituting the coordinates of B', C, and T into the expression for vector AT, we get:
AT = T - A
Simplifying this expression, we get:
AT = ((x - xA), (y - yA))
In triangle ABC, let B' and C' be points on sides CA and AB, respectively. B' divides CA in a 4:4 ratio from C, meaning CB':B'A = 4:4, and C' divides AB in a 3:5 ratio from A, meaning AC':C'B = 3:5.
Let A be the origin, and let AB = a and AC = b be the vectors forming a base in the plane. Since B' divides CA in half, the position vector of B' is the midpoint of CA, so B' = (1/2)b. Similarly, C' divides AB in a 3:5 ratio, so C' = (5/8)a.
Now, let's consider triangle B'C'T. Since T is the intersection of BB' and CC', we can write the vectors BT and CT in terms of B'T and C'T, respectively:
BT = B'T + TB
CT = C'T + TC
Since B'T and C'T are parallel to b and a, respectively, we can write:
BT = k1 * b
CT = k2 * a
Here, k1 and k2 are constants. Now, using the ratios CB':B'A and AC':C'B, we can write:
k1 * b = 4 * (TB - (1/2)b)
k2 * a = 5 * (TC - (5/8)a)
Finally, we want to find the vector AT. Since AT = TB + TC, we can substitute the expressions for TB and TC from the above equations and solve for AT:
AT = (k1 * b + (1/2)b) + (k2 * a + (5/8)a)
The coordinates of the vector AT are given in terms of the base vectors a and b, with the constants k1 and k2 accounting for the position of the point T in the triangle.

As per the given graph, there are 8 fewer students walk to school in Class A than in Class B
In this case, we are looking at two classes, Class A and Class B, and the number of students who walk to school in each class. The graph should show a picture or symbol for each student who walks to school.
Now, to answer the question of how many fewer students walk to school in Class A than in Class B, we need to compare the number of symbols or pictures for each class on the graph.
One way to do this is to count the number of symbols or pictures for each class and then subtract the number of students who walk to school in Class A from the number of students who walk to school in Class B.
This will give us the number of students that walk to school in Class B but not in Class A, which is the same as the number of fewer students who walk to school in Class A.
If there are 10 symbols for Class A and 18 symbols for Class B, then we can say that there are 8 fewer students who walk to school in Class A than in Class B.

ms. mcclain conducted an experiment with a -sided number cube. the table shows the number of times each number landed: for which number did the theoretical probability equal the experimental probability?
In this case, the theoretical and experimental probabilities are the same for the numbers 1 and 6, so the solution to the problem is 1 and 6.
The theoretical probability of an event is the expected probability based on mathematical analysis or theory.
The experimental probability of an event is the probability that is observed through actual experiments or trials.
To determine which number had the same theoretical and experimental probability in the experiment conducted by Ms. McClain with an n-sided number cube, you need to follow these steps:
Determine the total number of trials conducted in the experiment, denoted as T.
Determine the number of times each number landed during the experiment, denoted as n1, n2, n3,..., nN, where N is the number of sides on the cube.
Calculate the theoretical probability of each number, denoted as P1, P2, P3,..., PN, using the formula:
Pi = 1/N, where i is the number on the cube.
Calculate the experimental probability of each number, denoted as E1, E2, E3,..., EN, using the formula:
Ei = ni / T, where i is the number on the cube.
Compare each theoretical probability Pi to its corresponding experimental probability Ei.
The number that has the same theoretical and experimental probability is the solution to the problem.
For example, if the experiment was conducted with a 6-sided cube, and the table shows the following results:
Number 1 2 3 4 5 6
Trials 10 12 8 11 9 10
Then, you can calculate the theoretical probability of each number:
P1 = 1/6 = 0.1667
P2 = 1/6 = 0.1667
P3 = 1/6 = 0.1667
P4 = 1/6 = 0.1667
P5 = 1/6 = 0.1667
P6 = 1/6 = 0.1667
And the experimental probability of each number:
E1 = 10/60 = 0.1667
E2 = 12/60 = 0.2
E3 = 8/60 = 0.1333
E4 = 11/60 = 0.1833

Biologists stocked a lake with 400 fish and estimated the carrying capacity to be 9400. The number of fish grew to 570 in the first year. Round to 4 decimal places. A) Find an equation for the number of fish P(t) after t years P(t) = b) How long will it take for the population to increase to 3000 (half of the carrying capacity)? It will take ___
A)
The equation for the number of fish after t years is
P(t) = 9400 (1 - 0.9574 x e^{-0.0899t})
B)
It will take approximately 7.31 years for the fish population to increase to 3000.
We have,
A)
The equation for logistic growth is:
dP/dt = rP(1 - P/K)
where P is the population size, t is the time in years, r is the intrinsic growth rate, and K is the carrying capacity.
We know that at t = 0, P = 400, and at t = 1, P = 570.
We can use this information to find the value of r:
570 - 400 = r(1 - 400/9400)
r ≈ 0.0899
Now we can use the logistic growth equation to find P(t):
dP/dt = 0.0899P(1 - P/9400)
∫dP/(P(1 - P/9400)) = ∫0.0899dt
-ln|1 - P/9400| = 0.0899t + C
|1 - P/9400| = e^(-0.0899t - C)
1 - P/9400 = ±e^(-0.0899t - C)
P = 9400(1 - Ce^(-0.0899t))
We can use the initial condition P(0) = 400 to find the value of C:
400 = 9400(1 - Ce^0)
C ≈ 0.9574
The equation for the number of fish after t years.
P(t) = 9400 (1 - 0.9574 e^{-0.0899t})
B)
To find how long it will take for the population to increase to 3000, we need to solve the equation P(t) = 3000 for t.
3000 = 9400(1 - 0.9574e^(-0.0899t))
Dividing both sides by 9400 and rearranging.
e^(-0.0899t) = 1 - 3000/9400
e^(-0.0899t) ≈ 0.6808
Taking the natural logarithm of both sides.
-0.0899t ≈ ln(0.6808)
t ≈ 7.31 years
It will take approximately 7.31 years for the fish population to increase to 3000.
Thus,
The equation for the number of fish after t years is
P(t) = 9400 (1 - 0.9574 e^{-0.0899t})
It will take approximately 7.31 years for the fish population to increase to 3000.
