Find the measure of each angle indicated.​

The values of ∂z/∂r and ∂z/∂s. These partial derivatives will depend on the specific function F(u, v, w) provided.

To find ∂z/∂r and ∂z/∂s, we need to differentiate z = F(u, v, w) with respect to r and s.
Given that u = r^2, v = -2s^2, and w = ln(r) + ln(s), we can substitute these values into z = F(u, v, w).
So, z = F(r^2, -2s^2, ln(r) + ln(s)).
To find ∂z/∂r, we differentiate z with respect to r while treating s as a constant. This gives us:
∂z/∂r = ∂F/∂u * ∂u/∂r + ∂F/∂w * ∂w/∂r.
Similarly, to find ∂z/∂s, we differentiate z with respect to s while treating r as a constant. This gives us:
∂z/∂s = ∂F/∂v * ∂v/∂s + ∂F/∂w * ∂w/∂s.
Since we don't have the specific function F(u, v, w) mentioned in the question, we cannot determine the values of ∂z/∂r and ∂z/∂s. These partial derivatives will depend on the specific function F(u, v, w) provided.

a. To determine if events a and b are independent, we need to check if the probability of a occurring is affected by whether or not b occurs, and vice versa. We can calculate the probability of a given that b has occurred using the formula:

P(A|B) = P(A and B) / P(B)

Substituting in the values given in the question, we get:

P(A|B) = 0.5 / 0.9 ≈ 0.56

Since P(A|B) ≠ P(A), we can conclude that events a and b are not independent.

b. To compute the probability of a or b occurring, we can use the following formula:

P(A or B) = P(A) + P(B) - P(A and B)

Substituting in the values given in the question, we get:

P(A or B) = 0.6 + 0.9 - 0.5 = 1

Therefore, the probability of either event a or b occurring is 1 or 100%.

c. Events a and b are mutually exclusive if they cannot occur at the same time, i.e., if P(A and B) = 0. In this case, we have P(A and B) = 0.5, which means that a and b are not mutually exclusive. This makes sense since the probability of a or b occurring is greater than either event individually, indicating that there is some overlap between the two events.

Answer:

x = 45°

y = 90°

Step-by-step explanation:

    The 135° is on a line, so 180° - 135° = 45°

Since this is an isosceles triangle, x will be equal to 45° as well.

    The sum of a triangle's angles is 180°, so if we add them all together and subtract from 180° we will get our y.

180° - (45 + 45) = y

180° - 90° = y

90° = y

(a triangle can be both an isosceles and a right-triangle!)

You would need to contribute approximately $2,145.44 annually at the end of each year from ages 25 to 60 in order to receive an annual annuity of $54,301 from ages 65 to 95.

To determine the annual contribution required to receive an annual annuity of $54,301 for 30 years, we can use the present value of an annuity formula:

PV = P * [(1 - (1 + r)^(-n)) / r]

Where:

PV = Present Value of the annuity

P = Payment per period (annual annuity payment)

r = Interest rate per period (EAR)

n = Number of periods (number of years)

In this case, the payment per period is $54,301, the interest rate per period is 7.8% (EAR), and the number of periods is 30 years.

We need to find the present value of the annuity at age 25, which will be the accumulated value of the contributions from ages 25 to 60 until age 65.

PV = P * [(1 - (1 + r)^(-n)) / r]

PV = P * [(1 - (1 + 0.078)^(-30)) / 0.078]

Now, we can rearrange the formula to solve for P:

P = PV / [(1 - (1 + r)^(-n)) / r]

P = $54,301 / [(1 - (1 + 0.078)^(-30)) / 0.078]

Using a calculator, we can evaluate the expression to find that the annual contribution required is approximately $2,145.44.

Therefore, You would need to contribute approximately $2,145.44 annually at the end of each year from ages 25 to 60 in order to receive an annual annuity of $54,301 from ages 65 to 95.

The probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

To find the probability that the average number of hours of overtime worked by a random sample of 140 employees exceeds 20 hours, we can use the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 18.9 hours and the population standard deviation is 7.8 hours, we can calculate the standard error of the mean using the formula: standard error = population standard deviation / sqrt(sample size).

For this problem, the sample size is 140, so the standard error is 7.8 / sqrt(140) ≈ 0.659.

To calculate the probability, we need to standardize the sample mean using the z-score formula: z = (sample mean - population mean) / standard error.

In this case, the sample mean is 20 hours, the population mean is 18.9 hours, and the standard error is 0.659. Plugging these values into the formula, we get z = (20 - 18.9) / 0.659 ≈ 1.71.

Now, we can use a standard normal distribution table or calculator to find the probability associated with a z-score of 1.71. Looking up this value in the table, we find that the probability is approximately 0.9564.

Therefore, the probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

Radius =  12.10 cm

Diameter = 24.20 cm

Area = 459.73 cm²

Step-by-step explanation:

Circumference of a circle is given by the formula
\(C = 2\pi r\) where r = radius

Given C = 76 cm, π = 3.14,
76 = 2 · 3.14 · r

76 = 6.28r

r = 76/6.28

or

r = 12.10 cm

Diameter = 2 x radius = 2 x 12.10 = 24.20

Area = π · r²

= 3.14 · (12.10)²

= 459.73 cm²

On the basic of properties of Semi Strong form efficiency, we conclude the given statement that According to the Semi- strong form of efficiency, analysts who find unique information hidden in a company's published financial statements have an advantage over the rest of the market is False.

Semi Strong form :

The efficiency theory of the semi-strong format uses all publicly available information when calculating the current price of a stock, allowing investors to use either technical or fundamental analysis to find the best value in the market. We follow the belief that no higher return can be generated.

Those who agree with this version of theory believe that only information not available to the public can help investors drive returns to higher levels of performance than the general market. To test the semi -strong version of EMH, we can see if the stock price fluctuates up or down if private his message has been published before. For example, proposed mergers and ambiguous earnings announcements are known to insiders but not to the public. Therefore, this information will not be correctly reflected in the stock price until it is published. At this point, investors and traders take this new information into account, so the stock may bounce or fall depending on the nature of the news.

From the semi-strong efficiency information above, we can say that the information hidden in the company's published financial statements does not benefit the rest of the market.

On applying the Chain Rule, dy/dx = dy/du * du/dx, yields dy/dx = 5 * 0 = 0.

To find dy/dx, we need to use the Chain Rule. The Chain Rule states that if y = f(u) and u = g(x), then dy/dx = dy/du * du/dx. In this case, y = 10x3 + 5y2 and u = 25y, so dy/dx = dy/du * du/dx.

To find dy/du, we take the derivative of both sides of the equation. We get: 10x3 + 5y2 = 25y, and then we take the derivative with respect to y to get 5y2 = 25. We can solve this equation to get y = (25/5)1/2, or y = 5. Then, dy/du = 5.

To find du/dx, we take the derivative of both sides of the equation. We get: 10x3 + 5y2 = 25y, and then we take the derivative with respect to x to get 30x2 = 0. We can solve this equation to get x = 0, so du/dx = 0.

Finally, using the Chain Rule, we get dy/dx = dy/du * du/dx, so dy/dx = 5 * 0 = 0.

The directional derivative D₁ = (3x² + 4y)Uz + 4xUy.

To determine the equation of the tangent plane to the function f(x, y) = -3xy + y² at the point P(ro, Yo, zo) = (1, 2, -2):

Calculate the partial derivatives of f(x, y) with respect to x and y:

fₓ = -3y

fᵧ = -3x + 2y

Evaluate the partial derivatives at the point P:

fₓ(ro, Yo) = -3(2) = -6

fᵧ(ro, Yo) = -3(1) + 2(2) = 1

The equation of the tangent plane at point P can be written as:

z - zo = fₓ(ro, Yo)(x - ro) + fᵧ(ro, Yo)(y - Yo)

Substituting the values, we have:

z + 2 = -6(x - 1) + 1(y - 2)

Simplifying, we get:

-6x + y + z + 8 = 0

Therefore, the equation of the tangent plane is -6x + y + z + 8 = 0.

To find a unit vector normal to the tangent plane,

For the function f(x, y) = x³ + 4xy, the general expression for the directional derivative D₁ at some point (zo, yo) in the direction of a unit vector u = (Uz, Uy) is given by:

D₁ = ∇f · u

where ∇f is the gradient of f(x, y), and · represents the dot product.

The gradient of f(x, y) is calculated by taking the partial derivatives of f(x, y) with respect to x and y:

∇f = (fₓ, fᵧ)

= (3x² + 4y, 4x)

The directional derivative D₁ is then:

D₁ = (3x² + 4y, 4x) · (Uz, Uy)

= (3x² + 4y)Uz + 4xUy

Therefore, the general expression for the directional derivative D₁ is (3x² + 4y)Uz + 4xUy.
