The probability that exactly 2 of the elks captured are tagged is approximately 0.218, or 21.8%.

The probability that exactly 2 of the captured elks are tagged can be calculated using the hypergeometric distribution.

The total number of elks in the forest is 20, of which 5 are tagged and 15 are untagged. We are randomly capturing 4 elks for analysis.

The probability of selecting exactly 2 tagged elks can be calculated as follows:

P(2 tagged elks) = (C(5, 2) * C(15, 2)) / C(20, 4)

Here, C(n, r) represents the number of combinations of choosing r items from a set of n items. In this case, we are selecting 2 tagged elks from the 5 available and 2 untagged elks from the remaining 15.

Evaluating this expression:

P(2 tagged elks) = (10 * 105) / 4845

P(2 tagged elks) ≈ 0.218

Therefore, the probability that exactly 2 of the elks captured are tagged is approximately 0.218, or 21.8%.

The hypergeometric distribution is used in situations where we are sampling without replacement from a finite population. In this case, we have a total of 20 elks in the forest, 5 of which are tagged and 15 are untagged. We are capturing 4 elks randomly, without replacement, for analysis. The probability of selecting exactly 2 tagged elks can be calculated by considering the number of ways to choose 2 tagged elks from the 5 available and 2 untagged elks from the remaining 15. Dividing this by the total number of possible combinations of selecting 4 elks from the 20 elks in the forest gives us the probability

Step-by-step explanation:

Our basic problem looks like:

y = qx

When we plug in our variables, we get:

20 = q * 4

To isolate q, we divide both sides by 4:

20 / 4 = q * 4 / 4, which becomes:

5 = q, leading to 5x = y

now to plug in our 5 variable:

5 * 5 = 25 = y

To solve this problem, we'll need to use algebraic expressions. Let's start by breaking down the information given to us.

The problem states that we need to multiply a sum by -3. Let's call this sum "x." So, -3x is our first algebraic expression.

Next, the problem states that this result (which is -3x) is 3 less than the product of 8 and the opposite of the second. We can represent the opposite of the second as -y (since we don't know the value of the second number, we'll use "y" to represent it). So, the product of 8 and -y is -8y. The problem tells us that -3x is 3 less than -8y, so we can represent this with the expression -8y - 3.

Now we can set these two expressions equal to each other, since they both represent the same value:

-3x = -8y - 3

To solve for x and y, we'll need to use some algebraic manipulation. Let's start by isolating one of the variables. We can do this by adding 8y to both sides:

-3x + 8y = -3

Now let's isolate the other variable by dividing both sides by -3:

x - (8/3)y = 1

So we have two equations:

-3x + 8y = -3

x - (8/3)y = 1

We can use these equations to solve for x and y using a method like substitution or elimination. However, since the problem doesn't ask for specific values of x and y, we don't need to solve for them here.

In summary, the problem involved multiplying a sum by -3 and then finding the result of a specific equation involving that sum. We used algebraic expressions to represent the information given to us and then solved for the two variables involved (x and y) using algebraic manipulation.

EXPLANATION

The equation of the tangent plane to the surface z=2x^2 + y^2 - 5y at the point (1, 2, -4) is z = 9x + 6y - 16. To find the equation of the tangent plane, we need to determine the normal vector and use the point-normal form of the plane equation.

First, we find the partial derivatives of the surface equation with respect to x and y:

∂z/∂x = 4x

∂z/∂y = 2y - 5

Next, we evaluate these partial derivatives at the point (1, 2, -4):

∂z/∂x = 4(1) = 4

∂z/∂y = 2(2) - 5 = -1

These values represent the components of the normal vector to the tangent plane at the given point: N = (4, -1).

Using the point-normal form of the plane equation, we have:

4(x - 1) - 1(y - 2) + (z + 4) = 0

Simplifying this equation gives:

4x - y + z - 4 = 0

Rearranging the terms, we get the equation of the tangent plane:

z = -4x + y + 4

Therefore, the equation of the tangent plane to the surface at the point (1, 2, -4) is z = 9x + 6y - 16.

The cartesian equation of the curve \(r=2 \hspace{0.1cm} csc \hspace{0.1cm} \theta\) is \(y=2\).

A Cartesian equation is essential in mathematics. It corresponds to a mathematical formula that expresses the connection between elements as a function of their positions on a plane known as Cartesian.

A two-dimensional coordinate scheme called the Cartesian plane employs a horizontal x-axis and an upward y-axis to identify locations in space.

Given that, \(r=2 \hspace{0.1cm} csc \hspace{0.1cm} \theta\).

So, \(csc\hspace{0.1cm}\theta=cosec \hspace{0.1cm}\theta\).

The equation becomes as follows:

\(r=2cosec\hspace{0.1cm} \theta\)

By using the trigonometric equation \(cosec\hspace{0.1cm} \theta=\frac{1}{sin\hspace{0.1cm}\theta}\), we get

\(r= \frac{2}{sin \hspace{0.1cm} \theta}\)

Multiplying both sides by \(sin\hspace{0.1cm}\theta\), we get

\(r \hspace{0.1cm}sin\hspace{0.1cm}\theta =2\hspace{0.1cm}\frac{sin\hspace{0.1cm}\theta}{sin\hspace{0.1cm}\theta}\)

\(rsin\hspace{0.1cm}\theta=2\)

By the parametric equations \(x=rcos\hspace{0.1cm}\theta\) and \(y=rsin\hspace{0.1cm}\theta\), we get

\(y=2\)

It is a horizantal line.

Hence, the cartesian equation of the curve \(r=2 \hspace{0.1cm} csc \hspace{0.1cm} \theta\) is \(y=2\).

The cartesian equation for the curve is: y = 2 This is a horizontal line passing through the point (0,2).

To find a Cartesian equation for the curve given by the polar equation r = 2 csc(θ), we will convert the polar coordinates (r, θ) into Cartesian coordinates (x, y) using the following relationships:

x = r * cos(θ)
y = r * sin(θ)

Step 1: Express r in terms of θ
r = 2 csc(θ)

Step 2: Since csc(θ) = 1 / sin(θ), rewrite the equation as
r = 2 / sin(θ)

Step 3: Express x and y in terms of r and θ
x = r * cos(θ)
y = r * sin(θ)

Step 4: Substitute r from Step 2 into the y equation
y = (2 / sin(θ)) * sin(θ)
