Probability of a flight being early ≈ 0.1852 or 18.52%

To calculate the probability that a flight is early, we need to divide the number of early flights by the total number of flights:

Probability of a flight being early = Number of early flights / Total number of flights

In this case, the number of early flights is given as 50, and the total number of flights is the sum of all the different arrival statuses: early, on time, late, and canceled.

Total number of flights = Number of early flights + Number of on-time flights + Number of late flights + Number of canceled flights

Total number of flights = 50 + 150 + 25 + 45 = 270

Now, we can calculate the probability:

Probability of a flight being early = 50 / 270

≈ 0.1852 or 18.52%

Under the given conditions, the expression tan(θ) evaluates to -3/4.

To evaluate the expression tan(θ) given the conditions cos(θ) = -1/3 in quadrant III and sin(θ) = 1/4 in quadrant II, follow these steps:

Recall the definition of tangent in terms of sine and cosine:
tan(θ) = sin(θ) / cos(θ)

Use the given conditions for sine and cosine:
sin(θ) = 1/4 (in quadrant II)
cos(θ) = -1/3 (in quadrant III)

Substitute the given values into the tangent formula:
tan(θ) = (1/4) / (-1/3)

Simplify the expression by multiplying the numerator and the denominator by the reciprocal of the denominator:
tan(θ) = (1/4) * (-3/1)

Multiply the numerators and the denominators:
tan(θ) = (-3) / 4

So, the expression tan(θ) evaluates to -3/4 under the given conditions.

The dividends per share on preferred stock for four years is $0.12, $0.12, $0.12, $0.12 and for common stock is $0.057, $0.152, $0.220, $0.220.

To calculate the dividends per share for each class of stock, we need to first determine the total dividends paid in each year.

For the preferred stock, the dividends are cumulative, which means any unpaid dividends from previous years must be paid before any dividends can be paid to common stockholders. Therefore, we need to calculate the total amount of unpaid dividends for each year before we can determine the amount available for common stockholders.

To calculate the unpaid dividends for the preferred stock in each year, we need to multiply the number of shares of preferred stock by the dividend rate (3%) and subtract the dividends paid in that year.

Unpaid dividends for preferred stock:

1st year: (80,000 x $20 x 0.03) - $33,000 = $9,600

2nd year: (80,000 x $20 x 0.03) - $72,000 - $9,600 = $9,600

3rd year: (80,000 x $20 x 0.03) - $100,000 - $9,600 = $9,600

4th year: (80,000 x $20 x 0.03) - $100,000 - $9,600 = $9,600

Now we can calculate the total dividends available for common stockholders in each year by subtracting the unpaid dividends for preferred stock from the total dividends paid in that year.

Total dividends available for common stockholders:

1st year: $33,000 - $9,600 = $23,400

2nd year: $72,000 - $9,600 = $62,400

3rd year: $100,000 - $9,600 = $90,400

4th year: $100,000 - $9,600 = $90,400

Finally, we can calculate the dividends per share for each class of stock by dividing the total dividends by the number of shares outstanding.

Dividends per share:

Preferred stock:

1st year: $9,600 / 80,000 = $0.12 per share

2nd year: $9,600 / 80,000 = $0.12 per share

3rd year: $9,600 / 80,000 = $0.12 per share

4th year: $9,600 / 80,000 = $0.12 per share

Common stock:

1st year: $23,400 / 410,000 = $0.057 per share

2nd year: $62,400 / 410,000 = $0.152 per share

3rd year: $90,400 / 410,000 = $0.220 per share

4th year: $90,400 / 410,000 = $0.220 per share

Therefore, the dividends per share on each class of stock for each of the four years are as follows:

Preferred stock (dividends per share)

1st Year: $0.12 per share

2nd Year: $0.12 per share

3rd Year: $0.12 per share

4th Year: $0.12 per share

Common stock (dividends per share)

1st Year: $0.057 per share

2nd Year: $0.152 per share

3rd Year: $0.220 per share

4th Year: $0.220 per share

The possible y-coordinate of point C is 6

Step-by-step explanation:

The coordinate of a point is given by (x,y) where x is the horizontal distance from the origin on the x axis and y is the vertical distance from the origin.

Given Segment AB is on the line y = 2 and is 3 units long and Segment AB is on the line y = 2 and is 3 units long. The area of triangle ABC is 6 square units.

The area of a triangle = 1/2 × base × height

The value of that maximize the profit, und determine the corresponding price and total profit for the level of production is $52,500

Given,

Suppose that the demand equation for a monopolist is p=100−.02x and the cost function is C(x)=20x+10,000. Find the value of x that maximizes the profit and determine the corresponding price and total profit for this level of production.

Here we need to find the value of that maximize the profit.

As per the Monopolist maximizes profit by setting marginal costs (MC) equal to marginal revenue (MR).

Here the Marginal revenue is the first partial derivative of Total revenue (TR) function.

And the total revenue is the quantity (X) times price (P):

TR = P⋅X

=> (100−0.01X) X

=> 100X−0.02X

Then we get get marginal cost, take the partial derivative of the cost function with respect to x:

=> MC=∂c(X)/∂X:50

=> MR=MC/100−0.02X=50/100−50

=> 0.02X

=> 2500units

Then the price of X, plug in the value of x in the inverse demand function and solve for price:

=> P=100−0.01(2500)=$75

And the profit is the difference between Total revenue and Total costs:

=> ∏=TR−TC/TR = P⋅X

=> $75 × 2500 = $187,500

Finally, the total costs, plug in the value of x in the total cost function:

=> TC = 50(2500)+10,000

=> $135,000

=> ∏ = $187,500−$135,000

=> $52,500

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.

Answer: T

Step-by-step explanation:

To find the probability of the interval (-0.15 < z < 2.67) in a standard normal distribution, we can use the cumulative distribution function (CDF) of the standard normal distribution.

The CDF gives the probability that a standard normal random variable is less than or equal to a given value. In this case, we need to find the probability that z is less than or equal to 2.67 and subtract the probability that z is less than or equal to -0.15.

Using a standard normal distribution table or a statistical calculator, we can find the corresponding probabilities:

P(z < 2.67) ≈ 0.9960

P(z < -0.15) ≈ 0.4404

To find the probability of the interval (-0.15 < z < 2.67), we subtract the probability of z < -0.15 from the probability of z < 2.67:

P(-0.15 < z < 2.67) ≈ P(z < 2.67) - P(z < -0.15)

≈ 0.9960 - 0.4404

≈ 0.5556

Therefore, the probability of the interval (-0.15 < z < 2.67) in a standard normal distribution is approximately 0.5556.

The endpoints of the latus rectum of the parabola are \((\dfrac{1}{2} , \dfrac{1}{2} )\) and \((\dfrac{-1}{2} , \dfrac{1}{2} )\).

The latus rectum of a parabola is a line segment that passes through the focus and is perpendicular to the axis of symmetry.

Given: equation of the parabola is \(\(y = \frac{1}{2}x^2\)\).

For a parabola with equation \(\(y = \frac{1}{2}x^2\)\), the standard form is

    \(\(y = ax^2\)\)

and, the vertex of the parabola is at the origin (0, 0).

Now, the focus of the parabola is located at a distance of a units above the vertex, \(\(a = \dfrac{1}{2}\)\).

So, the focus is at \((0, \(a\))\) = \((0, \frac{1}{2} )\).

Since the axis of symmetry is the y-axis, the latus rectum will be a horizontal line.

The endpoints of the latus rectum will be equidistant from the focus and lie on a line parallel to the x-axis.

The distance from the focus to each endpoint of the latus rectum is twice the focal length, i.e., 2a = 1.

The endpoints of the latus rectum will be at a distance of 1 unit from the focus in the positive and negative x-directions.

So, the endpoints of the latus rectum are \((\dfrac{1}{2} , \dfrac{1}{2} )\) and \((\dfrac{-1}{2} , \dfrac{1}{2} )\).
