The correct probabilities are P(at least two tails) = 0. 5 and P(at least one heads) = 0. 875.

Let's calculate the probabilities based on the given sample space:

Total number of outcomes (sample space) = \(2^{3}\) = 8

P(one tails):

From the sample space, there are four outcomes that have exactly one tails: HTT, THT, TTH, TTT.

So, P(one tails) = 4/8 = 0.5

P(three heads):

From the sample space, there is only one outcome that has three heads: HHH.

So, P(three heads) = 1/8 = 0.125

P(one heads and two tails):

From the sample space, there are three outcomes that have one heads and two tails: HHT, HTH, THH.

So, P(one heads and two tails) = 3/8 = 0.375

P(at least two tails):

From the sample space, there are four outcomes that have at least two tails: TTH, THT, HTT, TTT.

So, P(at least two tails) = 4/8 = 0.5

P(at least one heads):

From the sample space, there are seven outcomes that have at least one heads: HHH, HHT, HTH, THH, THT, TTH, TTT.

So, P(at least one heads) = 7/8 = 0.875

Therefore, the correct probabilities are:

P(one tails) = 0.5

P(three heads) = 0.125

P(one heads and two tails) = 0.375

P(at least two tails) = 0.5

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Answer:

B. 200 km

Step-by-step explanation:

You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation

 170^2 +   150^2 = c^2

28900 + 22500 = c^2

                51400 = c^2

             √51400 = √c^2

                 ~226 = c

They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.

While writing this, I felt like I wasn't explaining well. Please feel free to ask for clarification if you need.

The distance between the planes is closest to 200km

You can use the Pythagorean theorem for this question.

First, we need to find a and b. This is gotten by calculating the distance between North and South, and the East and West. From the question, we can say that, 200 North - 30 North gives 170 miles with respect to the y-axis. In the same vein, we know that 50 East + 100 West gives us 150 kilometers which is with respect to the x-axis.

Since we have found our a and b to be 170 and 150, we then use Pythagoras to find the answer to the equation.

170² + 150² = c²

28900 + 22500 = c²

c² = 51400

c =\(\sqrt{51400}\)

c = ±226 km.

Since we can't have distance in negative, then our answer is 226 km. The answer asked us to find the closest distance, and thus, our answer is 200km.

The first-order optimality condition for convex optimization problems can be applied to characterize the optimal point, x* in the given optimization problem.

The first-order optimality condition states that if x* is an optimal point for the given convex optimization problem, then there exists a vector v* such that:

∇f(x*) + v* = 0

Here, ∇f(x*) is the gradient of the objective function f(x) evaluated at x*, and v* is the Lagrange multiplier associated with the constraint x ∈ C.

In the given optimization problem, the objective function is ∥a−x∥², and the constraint set is C.

To apply the first-order optimality condition, we need to find the gradient of the objective function. The gradient of ∥a−x∥² is given by:

∇f(x) = 2(x - a)

Now, let's apply the first-order optimality condition to the given problem:

∇f(x*) + v* = 0

Substituting the gradient expression:

2(x* - a) + v* = 0

Rearranging the equation:

x* = a - (v*/2)

This equation provides a characterization of the optimal point x* in terms of the Lagrange multiplier v*. By solving the equation, we can find the optimal point x*.

It's important to note that the Lagrange multiplier v* depends on the constraint set C. The specific form of v* will vary depending on the nature of the constraint set. In some cases, it may be necessary to further analyze the specific properties of the constraint set C to fully characterize the optimal point x*.

To show that u(x,y) = 2x−x^3+3xy^2 is harmonic, we need to demonstrate that it satisfies Laplace's equation, which states that the sum of the second partial derivatives of a function is zero. Let's calculate the Laplacian of u(x,y):

∇^2u(x,y) = (∂^2u/∂x^2) + (∂^2u/∂y^2)

= (2 - 6x^2) + 6y

Since both terms are independent of each other and the sum is zero, we can conclude that u(x,y) is indeed harmonic.

To find the harmonic conjugate v(x,y), we can use the fact that it satisfies the Cauchy-Riemann equations: (∂u/∂x) = (∂v/∂y) and (∂u/∂y) = - (∂v/∂x).

From the given function u(x,y), we can see that (∂u/∂x) = 2 - 3x^2 + 3y^2 and (∂u/∂y) = 6xy. By equating these expressions to (∂v/∂y) and - (∂v/∂x), respectively, we can solve for v(x,y).

(∂v/∂y) = 2 - 3x^2 + 3y^2

(∂v/∂x) = -6xy

Integrating the first equation with respect to y, we get v(x,y) = 2y - x^2y + y^3 + h(x), where h(x) is an arbitrary function of x.

Next, we differentiate this expression with respect to x and equate it to the second equation:

-6xy = (∂v/∂x) = -6xy + h'(x)

We can see that h'(x) = 0, which implies that h(x) is a constant. We can set this constant to zero without loss of generality.

Therefore, the harmonic conjugate of u(x,y) is v(x,y) = 2y - x^2y + y^3.

Hence, the function u(x,y) = 2x−x^3+3xy^2 is harmonic, and its harmonic conjugate is v(x,y) = 2y - x^2y + y^3.

The experimental (empirical) probability that the next child is a boy given that a family has five children: 3 boys and 2 girls is 0.6.

Given that the family has five children, 3 of whom are boys and 2 are girls. If we want to know the experimental probability that the next child is a boy, we need to find the ratio of the number of boys to the total number of children. Since the family has three boys and two girls, the total number of children is:
Total number of children = 3 + 2 = 5
Therefore, the probability of the next child being a boy is given by the ratio of the number of boys to the total number of children.
P(B) = Number of boys/Total number of children

34% of 30% = .30 x .34 = .102 = 10.2%

so A. 10.2% should be the answer.

10.2% of students who live off campus and do not have a part-time job

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

30% of students live off campus.

Of those who live off campus, 66% of those students work part-time.

so, the students off campus do not have a part time job.

= 100- 66

= 34%

Then, the percentage of students who live off campus and do not have a part-time job

= 34% of 30%

= 0.30 x 0.34

And we want to find the remainder after it is divided by the binomial:

\(x+4\)

We can use the Polynomial Remainder Theorem. According to the PRT, if we have a polynomial P(x) being divided by a binomial in the form (x - a), then the remainder will be given by P(a).

Here, our divisor is (x + 4). We can rewrite this as (x - (-4)).

Therefore, a = -4.

Then according to the PRT, the remainder will be:

\(f(-4)=(-4)^4-2(-4)^3-27(-4)^2-9(-4)+18=6\)

The remainder will be 6.

The equation of a circle whose center is (0,.-5) and radius is 7 as required is; (x - 0)² + (y + 5)² = 7².

The probability of a flood of the same magnitude, specifically a 50-year flood, occurring in 2021 would still be 2%.

The occurrence of a flood with a certain magnitude, such as a 50-year flood, is based on the concept of return periods. A 50-year flood refers to a flood event that has a 2% (1 in 50) chance of occurring in any given year.

It's important to note that the probability of a flood of the same magnitude occurring in the following year is independent of the previous flood event.

The fact that a 50-year flood occurred in 2020 does not affect the probability of a similar flood occurring in 2021.

The term "50-year flood" refers to a flood that has a 2% chance of occurring in any given year. It does not mean that a flood of the same magnitude will occur exactly every 50 years. Each year is independent of the previous year in terms of flood occurrence, and the probability remains the same each year.
