The value of h is 99.969.

The Esscher Premium Principle is a method of calculating insurance premiums that considers the risk of an event occurring and the potential severity of the loss. The formula for the Esscher Premium Principle is:

Ex = ln(∑eαx Px)/α

Where Ex is the Esscher premium, α is the parameter, x is the loss amount, and Px is the probability of the loss occurring.

In this case, we are given X (3, 0.02), meaning that the loss amount is 3 and the probability of the loss occurring is 0.02. We are also given that the Esscher premium is 300 and the parameter is 1. Plugging these values into the formula, we get:

300 = ln(∑e1(3) 0.02)/1

Simplifying the equation, we get:

300 = ln(0.02e3)

Taking the natural logarithm of both sides, we get:

e300 = 0.02e3

Dividing both sides by 0.02, we get:

e300/0.02 = e3

Taking the natural logarithm of both sides again, we get:

300 - ln(0.02) = 3

Solving for h, we get:

h = (300 - ln(0.02))/3

h = 99.969

Therefore, the value of h is 99.969.

Check out the diagram below. We have 3 pizza slices shaded out of 6 total to represent 3/6 of the entire thing. This is also 1/2 of the entire thing.

This is one visual way to see how 3/6 = 1/2.

You can multiply top and bottom of 1/2 to get 1*3 = 3 up top and 2*3 = 6 down below.

\(\frac{1}{2} = \frac{1*3}{2*3} = \frac{3}{6}\)

The answer is (f) None of the above.

We can use the inclusion-exclusion principle to find the cardinality of the set A ∪ (B ∩ C). The formula is:

n(A ∪ (B ∩ C)) = n(A) + n(B) + n(C) - n(B ∪ C) - n(A ∩ B ∩ C)

We are given the values of n(A), n(B), n(C), n(A ∩ B), n(B ∩ C), and n(C ∩ A) from the Venn diagram. We can use these values to find n(B ∪ C) and n(A ∩ B ∩ C) as follows:

n(B ∪ C) = n(B) + n(C) - n(B ∩ C)

n(A ∩ B ∩ C) = n(A) + n(B) + n(C) - n(A ∪ B) - n(B ∪ C) - n(C ∪ A) + n(A ∩ B ∩ C)

Substituting the values from the Venn diagram, we get:

n(B ∪ C) = 50 + 28 - 16 = 62

n(A ∩ B ∩ C) = 18 + 16 + 28 - 50 - 62 - 20 + 10 = 0

Therefore,

n(A ∪ (B ∩ C)) = n(A) + n(B) + n(C) - n(B ∪ C) - n(A ∩ B ∩ C) = 32 + 50 + 20 - 62 - 0 = 40

The equation in x and y for the line tangent to the curve x(t) = 10t + 46 and y(t) = 2t² + 20t + 56 at the point (10, 46).

By finding the derivatives of x(t) and y(t) with respect to t, we can determine the slope of the tangent line at any given point. Plugging in the value of t corresponding to the point (10, 46) into the derivatives will give us the slope of the tangent line at that point. Finally, using the point-slope form of a linear equation, we can write the equation of the tangent line in terms of x and y.

To find the equation of the line tangent to the curve x(t) = 10t + 46 and y(t) = 2t² + 20t + 56 at the point (10, 46), we need to determine the slope of the tangent line at that point. We start by finding the derivatives of x(t) and y(t) with respect to t.

The derivative of x(t) with respect to t gives us the rate of change of x with respect to t, which is the slope of the tangent line for the x-coordinate. Taking the derivative of x(t) = 10t + 46, we get dx/dt = 10.

The derivative of y(t) with respect to t gives us the rate of change of y with respect to t, which is the slope of the tangent line for the y-coordinate. Taking the derivative of y(t) = 2t² + 20t + 56, we get dy/dt = 4t + 20.

To find the slope of the tangent line at the point (10, 46), we substitute t = 10 into the derivatives: dx/dt = 10 and dy/dt = 4(10) + 20 = 60.

Now that we have the slope (m) of the tangent line, we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) represents the given point on the curve. Substituting (10, 46) and the slope m = 60, we get the equation of the tangent line:

y - 46 = 60(x - 10)

Simplifying the equation further, we have:

y - 46 = 60x - 600

This is the equation in x and y for the line tangent to the curve x(t) = 10t + 46 and y(t) = 2t² + 20t + 56 at the point (10, 46).

Answer:

Step-by-step explanation:

If the sine is negative then theta must be in Quadrant III or Quadrant IV.

If the tangent is positive then theta must be in Quadrant I or III.

If both conditions must be satisfied, then we conclude that thera is in Quadrant III.

Note that \(\tan\theta=\frac{\sin\theta}{\cos\theta}.\) Thus, if \(\sin\theta<0\) and \(\tan\theta>0,\) then we must have \(\cos\theta<0\) as well. The sine function is negative when \(\theta\) lies in Quadrant III or IV, and the cosine function is negative when \(\theta\) lies in Quadrant II or III. Thus, the two are both negative when \(\theta\) lies in Quadrant III, or \(\pi+2\pi n<\theta<\frac{3\pi}{2}+2\pi n\) for integer values of \(n.\)

The given statement is proven below:

(i) t(n + 1) = n t(n)

(ii) t(2) = 2t(1), t(3) = 3t(2), T() = √π

(i) To show that t(n + 1) = n t(n), we can use mathematical induction.

First, we establish the base case: t(2) = 2t(1). This is given in the problem statement.

Next, we assume that the equation holds for some arbitrary value k: t(k + 1) = k t(k).

Now, we need to prove that it holds for k + 1 as well: t((k + 1) + 1) = (k + 1) t(k + 1).

Using the recursive definition of t(n), we can rewrite the equation as t(k + 2) = (k + 1) t(k + 1).

Expanding t(k + 2) using the recursive definition, we have t(k + 2) = (k + 2) t(k + 1).

Since (k + 2) is equal to (k + 1) + 1, we can substitute it into the equation.

This gives us (k + 2) t(k + 1) = (k + 1) t(k + 1), which simplifies to t(k + 2) = (k + 1) t(k + 1).

Therefore, the equation t(n + 1) = n t(n) holds for all positive integers n.

(ii) To find the values of t(2), t(3), and T(), we can use the given initial conditions.

We are given that t(1) = 1. Using the recursive definition, we can find t(2) = 2t(1) = 2(1) = 2.

Similarly, t(3) = 3t(2) = 3(2) = 6.

Finally, we are given that T() = √π.

After factoring out the common term of xy from the numerator and denominator, the given algebraic fraction simplifies to \((x^2 - 2xy) / [(2y - x) y]\).

The given algebraic fraction is:

\((x^3y - 2x^2y^2) / (2xy^3 - x2y2)\)

To simplify the expression, we can factor out the common term of xy from both the numerator and denominator:

\((xy) (x^2 - 2xy) / (xy^2) (2y - x)\)

Now we can simplify further by canceling out the common factor of xy in the numerator and denominator:

\((x^2 - 2xy) / (2y - x) y\)

So the simplified form of the algebraic fraction is:

\((x^2 - 2xy) / (2y - x) y\)

To simplify an algebraic fraction, we want to find a way to write it in a form that is easier to work with. One common method is to factor out common terms in both the numerator and denominator.

Answer:

Question a)

\(9^{3x+4}=27^{4x+3}\)

\(x=-0.166\)

Question b)

\(4^{3x}=2^{x+1}\)

\(x=0.2\)

Step-by-step explanation:

Question a)

Given the expression

\(9^{3x+4}=27^{4x+3}\)

Taking log on both sides

\(log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)\)

\(\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)\)

\(3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)\)

\(3x+4=1.5\times \left(4x+3\right)\)

\(3x+4=6x+4.5\)

\(3x=6x+0.5\)

\(\frac{-3x}{-3}=\frac{0.5}{-3}\)

\(x=-0.166\)

Therefore, the value of x:

\(x=-0.166\)

Question b)

Similarly, we can solve the 'b' expression

Given the expression

\(4^{3x}=2^{x+1}\)

Taking log on both sides

\(log\left(4^{3x}\right)=log\left(2^{x+1}\right)\)

\(3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)\)

\(3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)\)

\(3x=0.5\times \left(x+1\right)\)

\(3x=0.5x+0.5\)

\(2.5x=0.5\)

Divide both sides by 2.5

\(\frac{2.5x}{2.5}=\frac{0.5}{2.5}\)

\(x=0.2\)

Therefore, the value of x = 0.2

Step-by-step explanation:

You have to set each individual equation equal to zero.

ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2

as for the y intercept I don't know

Answer:

see explanation

Step-by-step explanation:

g(x) = (x + 2)(x - 1)(x - 2)

To find the zeros let g(x) = 0 , then

(x + 2)(x - 1)(x - 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

The zeros are x = - 2, x = 1, x = 2

To find the y- intercept substitute x = 0 into g(x)

g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4

The y- intercept is 4 or (0, 4 )

The derivative of y = 30e^(-x^(2/3)) with respect to x is dy/dx = 30e^(-x^(2/3)) * -(2/3)x^(-1/3).

The inside function is u = -x^(2/3), and the outside function is y = 30e^u. Rewrite y in terms of u: y = 30e^(-x^(2/3)).

To find dy/dx using the chain rule, we need to differentiate the outside function with respect to the inside function (u) and then multiply it by the derivative of the inside function with respect to x. Applying the chain rule, we have:

dy/du = 30e^u  (derivative of the outside function with respect to u)

du/dx = -(2/3)x^(-1/3)  (derivative of the inside function with respect to x)

Now we can multiply these two derivatives together to find dy/dx:

dy/dx = dy/du * du/dx = 30e^u * -(2/3)x^(-1/3)

Substituting u = -x^(2/3) into the equation, we get:

dy/dx = 30e^(-x^(2/3)) * -(2/3)x^(-1/3)

Therefore, the derivative of y = 30e^(-x^(2/3)) with respect to x is dy/dx = 30e^(-x^(2/3)) * -(2/3)x^(-1/3).

a. In the function y = 30e^(-x^(2/3)), the inside function is -x^(2/3) denoted as u, and the outside function is y = 30e^u.

b. To differentiate the function using the chain rule, we start by finding the derivative of the outside function with respect to the inside function, which is dy/du = 30e^u. Then, we find the derivative of the inside function with respect to x, du/dx = -(2/3)x^(-1/3). Finally, we multiply these two derivatives together to obtain the derivative of the entire function with respect to x, which is dy/dx = 30e^(-x^(2/3)) * -(2/3)x^(-1/3).

Step-by-step explanation:

The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.

x^2 - 6x + 12 = 2x - 4

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x = 4

Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.

y = 2x - 4 = 2(4) - 4 = 4

Therefore, the solution of this system of equations is (4, 4).

False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.

In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.

When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.

In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.

However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.

Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.
