Answer:

A

Step-by-step explanation:

The correct answer is e(x) = np. The expected value for a binomial probability distribution is given by the formula e(x) = np, where n represents the number of trials and p represents the probability of success in each trial.

The expected value is a measure of the average or mean outcome of a binomial experiment. It represents the number of successful outcomes one would expect on average over a large number of trials.

The formula e(x) = np arises from the fact that the expected value of a binomial distribution is the product of the number of trials (n) and the probability of success (p) in each trial. This is because in a binomial experiment, the probability of success remains constant for each trial.

Therefore, to calculate the expected value of a binomial probability distribution, we multiply the number of trials by the probability of success in each trial, resulting in e(x) = np.

Step-by-step explanation:

\(A'B'=6, AB=4\)

The scale factor is the ratio of the lengths of a pair of corresponding sides. (image to preimage).

Thus, the scale factor is \(6/4=3/2\).

The three different equations are:

Equation 1: cos (0) = 1

Equation 2: cos (2π) = 1

Equation 3: cos (-2π) = 1

Explanation:

Given, cos (π) = -1. The other trigonometric functions that we can use are sine, tangent, cosecant, secant and cotangent.

So, the three equations that equal -1 are:

Equation 1: sin (3π/2) = -1

We know that, sin (3π/2) = sin (π/2 + π) = -cos (π/2) = -1

Equation 2: tan (5π/2) = -1

We know that, tan (5π/2) = tan (π/2 + 2π) = -cot (π/2) = -1

Equation 3: sec (2π) = -1

We know that, sec (2π) = sec (0 + 2π) = sec (0) = -1

Using cosine function, the three different equations are:

Equation 1: cos (0) = 1

For a card game with a pack of total 52 cards, where success is that drawn card is face card. The excepted value for this game is - 0.615.

In probability theory, Expected Value is the estimated gain or loss in partaking in an event many times. It is calculated by the formula written as \(E(X) = \sum P(X) × X \)

where, X is the number of trials and

In other words, sum of multiplication of probability of gain to gain amount and multiplication of probability of loss to loosing amount. We have a experiment card game. There is a total 52 card deck. Let's consider an event X that one card is drawn from 52.

Number of face cards in pack of 52 = 3× 4 = 12

Number of non- face cards in pack of 52 = 52 - 12 = 40

Probability that drawn card is face card or probability of success = 12/52 = \( \frac{ 3}{13}\)

Probability that drawn card is not face card or probability of loss = \( \frac{40}{52} = \frac{10}{13} \)

winning amount on probability of success= $4

So, excepted value = \(4 \times \frac{3}{13} - 2 \times \frac{10}{13} \)

= \( - \frac{8}{13} \) = - 0.615

Hence, required value is - 0.615.

Answer:

X = 65°

Y = 75°

Z = 65°

Step-by-step explanation:

Hello!

Angle Y and the angle measuring 75 degrees are corresponding angles, and corresponding angles are congruent to each other in degree measure.

There is also another set of corresponding angles, and those are Angle Z and Angle X.

Since Angle Y and 75° are corresponding, we can state that Angle Y is also 75°. We can now find Angle Z by subtracting 40° and 75° from 180°. This is because the sum of angles in a triangle is 180°.

The measure of Angle Z is 65°. We know that Z and X are corresponding, so X is also 65°.

 f(t) = L^(-1){1 / (s^2 + s)} Inverse Laplace transform tables or techniques, determine the time-domain function f(t) that satisfies the given integral equation.

The Laplace transform is a powerful mathematical tool that can be used to solve complex integral equations, like the one you've provided: f(t) + t * ∫(t - τ)f(τ)dτ = t.

To solve this equation using the Laplace transform, follow these steps:

1. Apply the Laplace transform to both sides of the equation. The Laplace transform of f(t) is F(s), and the Laplace transform of t is 1/s^2. The integral equation becomes:

  L{f(t)} + L{t * ∫(t - τ)f(τ)dτ} = L{t}

  F(s) + L{t * ∫(t - τ)f(τ)dτ} = 1/s^2

2. Next, apply the convolution theorem to the integral term. The convolution theorem states that L{f(t) * g(t)} = F(s) * G(s). In this case, f(t) = t and g(t) = (t - τ)f(τ):

  F(s) + L{t} * L{(t - τ)f(τ)} = 1/s^2

3. Now, substitute the known Laplace transforms for t and f(t):

  F(s) + (1/s^2) * F(s) = 1/s^2

4. Combine the terms containing F(s):

  F(s) * (1 + 1/s^2) = 1/s^2

5. Isolate F(s) by dividing both sides of the equation by (1 + 1/s^2):

  F(s) = (1/s^2) / (1 + 1/s^2)

6. Simplify the expression for F(s):

  F(s) = 1 / (s^2 + s)

7. Finally, apply the inverse Laplace transform to F(s) to obtain the solution for f(t):

  f(t) = L^(-1){1 / (s^2 + s)}

Using inverse Laplace transform tables or techniques, you can determine the time-domain function f(t) that satisfies the given integral equation.

To accurately summate for all ten numbers, the expression reads: Σ(2 + (n - 1) * 2) for n = 1 to 10.

An arithmetic sequence with a common difference of two gives us the following set of numbers:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20.

To fully explain this pattern using summation notation, we can apply the general formula for the nth term of any such sequence.

This formula is expressed by an = a1 + (n - 1) * d, wherein "an" stands for the nth term, "a1" represents the initial number in the sequence, "n" reflects the position of the said term within the series, and finally, "d" dictates the standard rate of difference between the terms.

Applying these variables to this example, it can be seen that a1 is 2, and d equals 2.

Thus, the equation simplifies to: an = 2 + (n - 1) * 2.

This integral is quite complex and does not have an analytical solution is 2pi ∫\(0^2\) \(e^{-r sin(\theta)\)) r (1 - 2\(r^2\)\(cos^{2}(\theta)\) (2\(-r^2\)) dr dtheta

To evaluate the triple integral of e^(x-y) over the region enclosed by the surfaces z=\(x^2-1, z=1-x^2, y=0,\) and y=8, we will use the cylindrical coordinates since the region is symmetric about the z-axis.

In cylindrical coordinates, we have:

x = r cos(theta)

y = r sin(theta)

z = z

The limits of integration for r, theta, and z are as follows:

0 <= r <= 2

0 <= theta <= 2pi

\(x^2\)-1 <= z <= 1-\(x^2\)

Substituting the cylindrical coordinates into the integral, we get:

∫∫∫ e^(x-y) dv = ∫∫∫ \(e^{(r cos(\theta) - r sin(\theta))\)r dz dr dtheta

Now, we need to determine the limits of integration for z in terms of r. Solving for z in the two equations that define the boundaries of the region, we get:

z =\(x^2\)- 1 -> z = \(r^2\)\(cos^2(\theta)\) - 1

z = 1 - \(x^2\) -> z = 1 - \(r^2\) \(cos^2(\theta)\))

Thus, the limits of integration for z become:

\(r^2 cos^2\)(theta) - 1 <= z <= 1 -\(r^2\) \(cos^2(\theta)\)

Substituting these limits into the integral and performing the integrations, we get:

∫∫∫ \(e^{r cos(\theta)\) - r sin(theta)) r (1 - \(r^2\) \(cos^2(\theta)\)) - \(r^2\) \(cos^2(\theta))\) dz dr dtheta

= ∫\(0^8\)∫\(0^2\)pi ∫\(0^2\) \(e^{r cos(\theta)\) - r sin(theta)) r (1 - 2\(r^2\) \(cos^2(\theta))\)dz dr dtheta

= 2pi ∫\(0^2\) \(e^{-r sin(\theta))\)r (1 - 2\(r^2\) \(cos^2(\theta))\) (2-\(r^2\)) dr dtheta

This integral is quite complex and does not have an analytical solution. Therefore, we need to evaluate it numerically using a computer or calculator.

The second ladder touches the wall approximately 11 feet higher than the shorter ladder, or equivalently, around 8 feet 8 inches higher.

Let's denote the height at which the second ladder touches the wall as h. We can set up a proportion based on the similar right triangles formed by the ladders and the building:

(6 6 feet) / (h) = (9 9 feet) / (5 5 feet 9 9 inches + h)

To solve for h, we can cross-multiply and solve the resulting equation:

(6 6 feet) * (5 5 feet 9 9 inches + h) = (9 9 feet) * (h)

Converting the measurements to inches:

(66 inches) * (66 inches + h) = (99 inches) * (h)

Expanding and rearranging the equation:

4356 + 66h = 99h

33h = 4356

Solving for h:

h = 4356 / 33 = 132 inches

Converting back to feet and inches:

h ≈ 11 feet

Therefore, the second ladder touches the wall approximately 11 feet higher than the shorter ladder, or equivalently, around 8 feet 8 inches higher.
