Answer: The value of P is 14.

Step-by-step explanation: To find the value of P, we can use the formula for the mean of a set of numbers:

mean = (sum of numbers) / (number of numbers)

We know that the mean of the set {6, 8, 9, P, 13} is 10. So we can write:

10 = (6 + 8 + 9 + P + 13) / 5

Multiplying both sides by 5, we get:

50 = 6 + 8 + 9 + P + 13

Combining like terms, we get:

50 = 36 + P

Subtracting 36 from both sides, we get:

14 = P

Therefore, the value of P is 14.

The CDF of Y is: FY(y) = FX((2 - y)/3)

= {1 - [tex]e^{(-4(2-y)/3)}[/tex], for y ∈ (-∞, 2]

{0, for y < -∞

To find the CDF of Y, we need to first find the range of Y:

Y = g(X) = 2 - 3X

When X = 0, Y = 2

As X approaches infinity, Y approaches negative infinity

Thus, the range of Y is (-∞, 2].

Now, let's find the CDF of Y for y ∈ (-∞, 2]:

FY(y) = P(Y ≤ y) = P(2 - 3X ≤ y)

Solving for X:

X = (2 - y)/3

Since FX(x) = P(X ≤ x), we can substitute (2 - y)/3 for x in FX(x) to get:

FX((2 - y)/3) = P(X ≤ (2 - y)/3)

= 1 - [tex]e^{(-4(2-y)/3)}[/tex], for y ∈ (-∞, 2]

a.) Both defective cylinders are selected:  the probability of both defective cylinders being selected is 1/28. b.) No defective cylinder is selected:  the probability of no defective cylinder being selected is 15/28. c.) At least one defective cylinder is selected: the probability of selecting at least one defective cylinder is 13/28.

a. The probability of selecting both defective cylinders can be calculated by multiplying the probability of selecting the first defective cylinder (which is 2/8, or 1/4 since there are 2 defective cylinders out of 8 total) by the probability of selecting the second defective cylinder given that the first one was already selected (which is 1/3 since there are now only 3 cylinders left and only 1 of them is defective). So the probability of both defective cylinders being selected is (1/4) x (1/3) = 1/12.
b. The probability of selecting no defective cylinder can be calculated by selecting two non-defective cylinders from the six remaining ones. The probability of selecting the first non-defective cylinder is 6/8 (or 3/4) and the probability of selecting the second non-defective cylinder given that the first one was already selected is 5/7. So the probability of selecting no defective cylinder is (3/4) x (5/7) = 15/28.
c. The probability of selecting at least one defective cylinder can be calculated by subtracting the probability of selecting no defective cylinder from 1 (since either at least one defective cylinder is selected or no defective cylinder is selected). So the probability of selecting at least one defective cylinder is 1 - (15/28) = 13/28.

The average value of f(x) = 3x^2 + 5x on the interval [3, 7] is 109, and the value of C for which f(c) = f_average is approximately 3.99.

a) To determine the average value of f(x) on the interval [7, 3], you need to calculate the integral of the function over the interval and divide it by the width of the interval. First, we need to correct the interval [7, 3] to [3, 7] since the smaller number should come first. The width of the interval is 7 - 3 = 4.

∫(3x^2 + 5x) dx from 3 to 7 = [(x^3 + (5/2)x^2) evaluated from 3 to 7] = [(7^3 + (5/2)7^2) - (3^3 + (5/2)3^2)] = 436.

Now, we divide this by the width of the interval: f_average = 436/4 = 109.

b) To find the value of C, we need to solve f(c) = f_average on the interval [3, 7]. We are given that f(c) = f_average = 109, so we set the function equal to the average value and solve for c:

3c^2 + 5c = 109

3c^2 + 5c - 109 = 0

This quadratic equation can be solved using the quadratic formula, factoring, or other methods, but it does not factor easily. Using the quadratic formula, you will find two possible values for c: approximately 3.99 and -9.16. Since -9.16 is not within the interval [3, 7], the value of c is approximately 3.99.

So, On the range [3, 7], the average value of f(x) = 3x2 + 5x is 109, and the value of C for which f(c) = f_average is roughly 3.99.

The income has increased by 10%.

Let's assume that the original price of the product was P, and the original quantity sold was Q. Then, the original income (revenue) would be:

Income1 = P x Q

After the price decreased by 12%, the new price would be:

P2 = P - 0.12P = 0.88P

And the new quantity sold would be 25% higher than the original quantity, or:

Q2 = 1.25Q

The new income would be:

Income2 = P2 x Q2 = (0.88P) x (1.25Q) = 1.1PQ

Therefore, the percent change in income would be:

[(Income2 - Income1) / Income1] x 100% = [(1.1PQ - PQ) / PQ] x 100%

To evaluate the integral, we can use substitution. Let u = 49-x², then du/dx = -2x, or dx = -du/(2x). Substituting this into the integral, we get:

∫ x²(49-x²)³/² dx = ∫ x²u³/²(-du/(2x)) = -1/2 ∫ u³/² du = -1/2 * (2/5) u^(5/2) + C

Substituting u = 49-x² back into the expression, we get:

The highest temperature on the surface of the sphere is 64000sqrt(55), and the lowest temperature is -64000sqrt(55).

Using Lagrange multipliers, we want to optimize the temperature function subject to the constraint of the sphere equation:

F(x, y, z) = 400xyz

G(x, y, z) = x^2 + y^2 + z^2 - 22 = 0

The Lagrangian function is:

L(x, y, z, λ) = F(x, y, z) - λG(x, y, z) = 400xyz - λ(x^2 + y^2 + z^2 - 22)

Taking partial derivatives with respect to x, y, z, and λ and setting them to zero, we get:

400yz - 2λx = 0

400xz - 2λy = 0

400xy - 2λz = 0

x^2 + y^2 + z^2 - 22 = 0

Solving the first three equations for x, y, and z, we get:

x = 200yz/λ

y = 200xz/λ

z = 200xy/λ

Substituting these into the sphere equation, we get:

(200yz/λ)^2 + (200xz/λ)^2 + (200xy/λ)^2 - 22 = 0

Simplifying this equation and solving for λ, we get:

λ = ±80sqrt(55)

Using these values of x, y, z, and λ, we can find the corresponding temperature values:

T(x, y, z) = 400xyz = ±64000sqrt(55)

Therefore, the highest temperature on the surface of the sphere is 64000sqrt(55), and the lowest temperature is -64000sqrt(55).

Answer:

The rate of change for height is 1/6 cubic feet/min at 2 min.

Step-by-step explanation:

The rate of change of the volume of the hailstone is 108π mm³/min when the radius is 3 mm.

The formula for the volume of a sphere is V = (4/3)πr³, where V is the volume and r is the radius.

We can use implicit differentiation to find the rate of change of the volume with respect to time.

Taking the derivative of both sides with respect to time t, we get:

dV/dt = d/dt[(4/3)πr³]

Using the chain rule, we get:

dV/dt = (4/3)π×3r² dr/dt

Now, we substitute the given values to find dV/dt at the moment when the radius is 3 mm:

r = 3 mm

dr/dt = 2 mm/min

dV/dt = (4/3)π × 3(3)² × 2

dV/dt = (4/3)π × 27 × 2

= 72π mm³/min

The weight that separates the bottom 5% is approximately 5.02 ounces.

To find the weights that separate the top 5% and the bottom 5%, we need to use the z-score formula and the standard normal distribution table.

First, let's find the z-score for the top 5%. Using the standard normal distribution table, we find that the z-score for the top 5% is approximately 1.645.

Next, we can use the formula z = (x - μ) / σ, where z is the z-score, x is the weight we're trying to find, μ is the mean, and σ is the standard deviation.

For the top 5%, we have:

1.645 = (x - 5.12) / 0.07

Solving for x, we get:

x = 5.12 + 1.645 * 0.07

x ≈ 5.22 ounces

Therefore, the weight that separates the top 5% is approximately 5.22 ounces.

To find the weight that separates the bottom 5%, we use the same process but with a negative z-score. The z-score for the bottom 5% is approximately -1.645.

-1.645 = (x - 5.12) / 0.07

Solving for x, we get:

x = 5.12 - 1.645 * 0.07

x ≈ 5.02 ounces

Therefore, the weight that separates the bottom 5% is approximately 5.02 ounces.

These weights could serve as limits used to identify which components should be rejected. Any component with a weight less than 5.02 ounces or greater than 5.22 ounces should be rejected.

A(1-6t) + ½ - 6B = g(t)

To solve for A and B, we need to have information about the function g(t). Once we have that, we can solve for A and B and find the particular solution to the differential equation.

In summary, the solution to the associated homogeneous equation is y(t) = c1e^(√6t) + c2e^(-√6t), and the particular solution to the differential equation can be found using the method of undetermined coefficients with information about the function g(t).

Answer:

= -77

Step-by-step explanation:

11/2 x -14 =

Express 11/2 (-14) as a single fraction.

11(-14)/2

Multiply 11 and -14 to get -154.

-154/2

Divide -154 by  2 to get -77.

-77.

It would take the trout 150 seconds to swim 100 yards.

We know that the trout swims at a speed of 2 feet per second. This means that for every second the trout swims, it covers a distance of 2 feet.

So, 100 yards x 3 feet/yard = 300 feet.

Now that we know the distance that the trout needs to cover, we can use the formula:

time = distance ÷ speed

where time is the time it takes for the trout to swim the given distance, distance is the distance the trout needs to cover (in feet), and speed is the speed at which the trout swims (in feet per second).

time = 300 feet ÷ 2 feet per second

time = 150 seconds.
