The revenue function, R(x), for the Walter Serkin recording of Beethoven's Moonlight Sonata produced by Phonola Media can be found using the equation p = -0.00043x + 8, which gives R(x) = px = (-0.00043x + 8)x.

To find the profit function, P(x), subtract the cost function, C(x) = 600 + 2x - 0.00004x^2, from the revenue function: P(x) = R(x) - C(x) = (-0.00043x + 8)x - (600 + 2x - 0.00004x^2).

Next, find the derivative of the profit function, P'(x), and set it to zero to find the critical number. This will help determine the number of discs Phonola should produce each month to maximize profits.

Following these steps, Phonola should produce approximately 7,692 discs per month to maximize profits.

The equation, 4 - 0.25g + 0.5h, will be evaluated as equal to: 4.

To evaluate an equation, plug in the values of the variables in the equation and solve to get the simplified value.

Given the equation, 4 - 0.25g + 0.5h, where:

g = 10

h = 5

Substitute g = 10 and h = 5 into the equation 4 - 0.25g + 0.5h, then evaluate:

4 - 0.25(10) + 0.5(5)

Simplify

= 4 - 2.5 + 2.5

= 4 + 0

= 4

Therefore, if g = 10 and h = 5, the equation 4 - 0.25g + 0.5h, is evaluated as: 4.

The Question:

The required heat equation is u(x, t) = (A×cos(λx) + B×sin(λx)) × exp(-λ²t)

To solve the heat equation in the given interval [-6, 0], we can use the separation of variables method. Let's denote the dependent variable as u(x, t), where x represents the spatial variable and t represents the temporal variable.

The heat equation in one dimension is given by:

∂u/∂t = α ∂²u/∂x²,

where α is the thermal diffusivity constant.

To solve this equation, we assume that the solution can be represented as a product of two functions, each depending on a single variable:

u(x, t) = X(x)T(t).

Substituting this into the heat equation, we have:

X(x)T'(t) = αX''(x)T(t),

where prime (') denotes differentiation with respect to the variable.

Dividing both sides by αX(x)T(t), we get:

T'(t)/T(t) = αX''(x)/X(x).

Since the left side depends only on t and the right side depends only on x, both sides must be equal to a constant, which we'll denote as -λ²:

T'(t)/T(t) = -λ² = αX''(x)/X(x).

Now, let's solve the temporal part of the equation:

T'(t)/T(t) = -λ²

This is a separable ordinary differential equation (ODE), and its general solution is given by:

T(t) = exp(-λ²t).

Next, let's solve the spatial part of the equation:

αX''(x)/X(x) = -λ².

This is also a separable ODE, and its general solution is given by:

X(x) = A×cos(λx) + B×sin(λx),

where A and B are arbitrary constants.

Therefore, the general solution to the heat equation is:

u(x, t) = (A×cos(λx) + B×sin(λx)) × exp(-λ²t).

Since we have the given interval [-6, 0], we can apply appropriate boundary conditions to determine the values of A, B, and λ that satisfy the problem.

The area of the shaded region is approximately 18.38 square feet.

To find the area of the shaded region between the larger circle with a radius of 10.2 feet and the smaller circle with a radius of 5.4 feet, we can use the concept of circle sectors.

The area of a circle sector can be calculated by finding the difference between the area of the corresponding triangle and the area of the circular segment.

First, let's calculate the area of the larger circle:

A_large = π(10.2)^2

Next, we calculate the area of the smaller circle:

A_small = π(5.4)^2

To find the area of the shaded region, we need to find the difference between the two circle sectors formed by the radii of the larger and smaller circles.

The angle of the sector formed by the radii can be found using trigonometry. Let's call it θ.

sin(θ) = (10.2 - 5.4) / 10.2

sin(θ) = 0.4706

Using inverse sine, we find θ ≈ 28.15 degrees.

Now we can calculate the area of the shaded region:

Shaded area = (θ / 360°) * A_large - (θ / 360°) * A_small

Shaded area ≈ (28.15 / 360) * π(10.2)^2 - (28.15 / 360) * π(5.4)^2

Shaded area ≈ (0.0782) * π(104.04) - (0.0782) * π(29.16)

Shaded area ≈ 8.1403π - 2.2832π

Shaded area ≈ 5.8571π

Finally, to approximate the value, we use the approximation π ≈ 3.14159:

Shaded area ≈ 5.8571 * 3.14159

Shaded area ≈ 18.38 square feet.

Therefore, the area of the shaded region is approximately 18.38 square feet.

Doubt clarification - use comment section.

The median of X is 1;  P(X > 2) = 0; P(one observation < 2 and the other > 2) = P(X < 2) * P(X > 2) = 0 * 0 = 0; Var(X) is approximately 0.33; E(X) is 1 and  the value of q such that P(X < q) = 0.95 is 1.9.

(a) To find the median of X, we need to find the value of x for which the cumulative distribution function (CDF) equals 0.5.

Since the PDF is given as f(x) = 1/2 for 0 < x < 2 and 0 otherwise, the CDF is the integral of the PDF from 0 to x.

For 0 < x < 2, the CDF is:

F(x) = ∫(0 to x) f(t) dt = ∫(0 to x) 1/2 dt = (1/2) * (t) | (0 to x) = (1/2) * x

Setting (1/2) * x = 0.5 and solving for x:

(1/2) * x = 0.5;  x = 1

Therefore, the median of X is 1.

(b) To find P(X > x), we need to calculate the integral of the PDF from x to infinity.

For x > 2, the PDF is 0, so P(X > x) = 0.

Therefore, P(X > 2) = 0.

(c) To find the probability that one observation is less than 2 and the other is greater than 2, we need to consider the possibilities of the first observation being less than 2 and the second observation being greater than 2, and vice versa.

P(one observation < 2 and the other > 2) = P(X < 2 and X > 2)

Since X follows a continuous uniform distribution from 0 to 2, the probability of X being exactly 2 is 0.

Therefore, P(one observation < 2 and the other > 2) = P(X < 2) * P(X > 2) = 0 * 0 = 0.

(d) The variance of X can be calculated using the formula:

Var(X) = E(X²) - [E(X)]²

To find E(X²), we need to calculate the integral of x² * f(x) from 0 to 2:

E(X²) = ∫(0 to 2) x² * (1/2) dx = (1/2) * (x³/3) | (0 to 2) = (1/2) * (8/3) = 4/3

To find E(X), we need to calculate the integral of x * f(x) from 0 to 2:

E(X) = ∫(0 to 2) x * (1/2) dx = (1/2) * (x²/2) | (0 to 2) = (1/2) * 2 = 1

Now we can calculate the variance:

Var(X) = E(X²) - [E(X)]² = 4/3 - (1)² = 4/3 - 1 = 1/3 ≈ 0.33

Therefore, Var(X) is approximately 0.33.

(e) The expected value of X, E(X), is given by:

E(X) = ∫(0 to 2) x * f(x) dx = ∫(0 to 2) x * (1/2) dx = (1/2) * (x²/2) | (0 to 2) = (1/2) * 2 = 1

Therefore, E(X) is 1.

(f) The value of q such that P(X < q) = 0.95 can be found by solving the following equation:

∫(0 to q) f(x) dx = 0.95

Since the PDF is constant at 1/2 for 0 < x < 2, we have:

(1/2) * (x) | (0 to q) = 0.95

(1/2) * q = 0.95

q = 0.95 * 2 = 1.9

Therefore, the value of q such that P(X < q) = 0.95 is 1.9.

As we can see in the graph, the triangle KXH has been reflected both on the y-axis and x-axis and then reduce by a scale factor between 0 and 1.

Reflection on both the y-axis and x-axis can be renamed to a single transformation which is a rotation of 180° about the origin. The transformation rule of a rotation about the origin is (x, y) → (-x, -y).

From the original coordinates of the triangle KXH, after rotation of 180° about the origin, the new coordinates are:

Now, if we compare the coordinates of triangle NGP and the new coordinates after the rotation:

We can see that the new coordinates after rotation was multiplied by 1/2 to form the coordinates of the Triangle NGP.

Hence, after a 180° rotation, the triangle KXH is dilated by a scale factor of 1/2. In symbol, this can be written as:

If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.

So, the answer is:

a. MSwithin > MSbetween

If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.
