Therefore, the estimated population of great white sharks that have migrated from Mexico to Hawaii is 2,500.

Shark population estimation is the process of determining the size and trends of shark populations in a given area. It involves collecting and analyzing data on shark abundance, distribution, behavior, and other factors to understand their population dynamics.

There are different methods used to estimate shark populations, including mark-recapture studies, aerial surveys, acoustic tracking, and genetic analysis. These methods allow researchers to estimate the number of sharks in a given area, monitor changes in their population over time, and identify potential threats to their survival.

To estimate the population of great white sharks that have migrated from Mexico to Hawaii, we can use the capture-recapture method, also known as the Lincoln-Petersen index.

Let:

The Lincoln-Petersen index formula is:

\(N = (n_1 * n_2 * n_3) / (m_1 * m_2 * m_3)\)

Plugging in the given values, we get:

\(N = (45 * 20 * 20 * 20) / (3 * 2 * 4)\)

\(N = 60,000 / 24\)

\(N = 2,500\)

To find the area of g([0, 12] ×[0, 6]), we need to first find the image of the rectangle [0, 12] ×[0, 6] under the inverse transformation g. Hence, the area of g([0, 12] ×[0, 6]) is 72 square units.

To find the area of g([0, 12] ×[0, 6]), we need to first find the image of the rectangle [0, 12] ×[0, 6] under the inverse transformation g

Since g is the inverse of f, we can express x and y in terms of u and v:

x = (v + 4u)/41

y = (4u - 5v)/41

Thus, the inverse transformation g maps the point (u, v) in the uv-plane to the point (x, y) in the xy-plane, where x and y are given by the above formulas.

Now, we can find the image of the rectangle [0, 12] ×[0, 6] under g as follows:

g([0, 12] ×[0, 6]) = {(x, y) | 0 ≤ x ≤ 12, 0 ≤ y ≤ 6, x = (v + 4u)/41, y = (4u - 5v)/41}

Substituting v = x - y into the equation for u, we get:

u = (5x + 9y)/41

Substituting this expression for u into the equations for x and y, we get:

x = (4/41)x + (5/41)y

y = (-5/41)x + (4/41)y

These equations define a linear transformation of the xy-plane. The matrix representation of this transformation with respect to the standard basis {(1, 0), (0, 1)} is:

[4/41 5/41]

[-5/41 4/41]

The determinant of this matrix is:

det([4/41 5/41]

[-5/41 4/41]) = (4/41)(4/41) + (5/41)(5/41) = 41/41 = 1

Therefore, the transformation is area-preserving, and the area of g([0, 12] ×[0, 6]) is the same as the area of [0, 12] ×[0, 6], which is:

A = 12 × 6 = 72

Hence, the area of g([0, 12] ×[0, 6]) is 72 square units.

The volume of the canister is 339.1 cubic inches.

The volume of a cylinder is calculated by using the formula V=πr²h, where r is the radius of the cylinder and h is the height of the cylinder.

The radius of the cylinder is half of the diameter, so the radius of the canister is 3 inches.

Using the formula, we can calculate the volume of the canister as follows:

V = π×3²×12

V = 108×3.14

V = 339.1 cubic inches

The equation of the  given model is y = 13.16x + 251.05

First choose two point

The first point = (44, 830)

The second point = (63, 1080)

The slope of the line m = \(\frac{y_2-y_1}{x_2-x_1}\)

Substitute the values in the equation

The  slope of the line = (1080-830) / (63 - 44)

= 250 / 19

Consider the point (44, 830)

The point slope form is

\(y-y_1=m(x-x_1)\)

Where m is the slope of the line

y - 830 = 250/19(x - 44)

y - 830 = (250/19)x - 11000/19

y = (250/19)x - 11000/19 + 830

y = 250/19 x + 4770/19

y = 13.16x + 251.05

Hence, the equation of the  given model is y = 13.16x + 251.05

Answer:

y = - x + 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 1 , then

y = - x + c ← is the partial equation

to find c substitute (2, 4 ) into the partial equation

4 = - 2 + c ( add 2 to both sides )

6 = c

y = - x + 6 ← equation of line

The following Java code can be used to solve the given problem:

```public static int getDaysToReachID(long id) { double salary = 0.001; int days = 0; while (salary < id) { salary *= 2; days++; } return days; }```

Explanation:

The given problem can be solved by using a while loop which continues until the salary becomes at least as large as the given ID.

The number of days required to reach the given salary can be calculated by keeping track of the number of iterations of the loop (i.e. number of days).

The initial salary is given as 0.001 AED and it gets doubled every day.

Therefore, the salary on the n-th day can be calculated as:

0.001 * 2ⁿ

A while loop is used to calculate the number of days required to reach the given ID. In each iteration of the loop, the salary is doubled and the number of days is incremented.

The loop continues until the salary becomes at least as large as the given ID. At this point, the number of days is returned as the output.

Answer:

y=4x-9

Step-by-step explanation:

add 4x to both sides to isolate y

Answer:

The slope-intercept form of this equation would be y = 4x - 9.

(For explanation look down below)  

Step-by-step explanation:

Slope-intercept form would be an equation that would look like...

y = mx + b

Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...

y - 4x = - 9

y - 4x + 4x = - 9 + 4x

y = 4x - 9

The statement "A histogram with the hills to the far left means the image is overexposed" is not accurate. In fact, a histogram with the hills to the far left indicates that the image is underexposed, not overexposed.

A histogram is a graphical representation of the distribution of pixel values in an image. It displays the frequency of occurrence of different tonal values. The horizontal axis represents the tonal values, while the vertical axis represents the frequency or number of pixels.

When the hills of the histogram are concentrated towards the left side, it means that a significant portion of the image has darker or lower tonal values. This indicates an underexposed image, where the exposure settings were insufficient to capture enough light, resulting in a darker overall appearance.

Conversely, an overexposed image would have the hills of the histogram concentrated towards the right side, indicating that a significant portion of the image has brighter or higher tonal values.

Therefore, the correct interpretation is that a histogram with the hills to the far left means the image is underexposed, not overexposed.

Using the coordinate points the graph is obtained for a trapezoid.

What is a trapezoid?

A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.

To graph the points (-3, -5), (5, 1), (2, 3) and (-2, 0), we can plot them on a coordinate plane.

From the graph, we can see that the points do not lie on a straight line. Instead, they form a shape that looks like a quadrilateral.

We can confirm this by connecting the dots between the points.

The shape formed by connecting the points is a quadrilateral.

Specifically, it looks like a trapezoid, since one pair of opposite sides are parallel (the segment connecting (-2,-0) and (2,3) is parallel to the segment connecting (-3,-5) and (5,1)).

Therefore, the shape obtained is a trapezoid.

Answer:

836 cm^2

Step-by-step explanation:

30 *30 = 900

4*4=16 *4=64

900-64 = 836cm^2

Answer:

836\(cm^{2}\)

Step-by-step explanation:

So we know x = 30, which means to find the area you just do 30 x 30 which equals 900 (perimeter is when you add it all).

We also know that each square has an area of 16, because we're given one side length, and the ticks in the middle of each line means they are congruent, which means that they are equal to each other.

So now we can multiply 16 by 4 because there are 4 squares. 16 x 4 = 64

Now, we just subtract 64 from 900. 900 - 64 = 836

Where, a is the the side of the square.

We have,

Side of the square garden = 30 ft.
