Answer:

Step-by-step explanation:

The probability that both Mr. & Mrs. Whelm will be alive after 10 years from now is 0.48 or 48%.

As per the question, probability of retired man living another 10 years is 0.8, hence P(man alive after 10 years) = 0.8

The probability of retired woman living another 10 years is 0.6, hence P(woman alive after 10 years) = 0.6

The given events are independent, hence the probability of both man & woman being alive after 10 years is given by the multiplication rule.

Hence, the probability of man & woman being alive after 10 years is

⇒ P(man alive after 10 years) × P(woman alive after 10 years)

⇒ 0.8 × 0.6 = 0.48

y = x^2 -5x-6 is a quadratic equation.

On a graph, rather than a straight line, this type of equation forms what is known as a parabola, which means it goes one direction and then makes almost like a U-turn.

The point in which the parabola (as mentioned before) changes direction is called the vertex.

Specifically, y = x^2 -5x-6 has exactly 2 solutions. This means that there are 2 different possible answers to this equation.

The solutions, or roots, to this equation are x= 6 and x= -1.

If you look at the graph for this equation, the parabola opens upwards like a U, and the vertex is ( 5/2, -49/4).

No, f(x, y) = 3x - 3y^2 is not a harmonic function.

A harmonic function is a twice continuously differentiable function f(x, y) that satisfies the Laplace equation:
                                                                            ∂²f/∂x² + ∂²f/∂y² = 0.

Let's check if f(x, y) = 3x - 3y^2 satisfies the Laplace equation:
∂²f/∂x² = ∂/∂x(3) = 0
∂²f/∂y² = ∂/∂y(-6y) = -6
∂²f/∂x² + ∂²f/∂y² = 0 + (-6) = -6 ≠ 0

Since the Laplace equation is not satisfied, f(x, y) = 3x - 3y^2 is not a harmonic function.

As for finding a corresponding analytic function, an analytic function is a function that is locally given by a convergent power series. Since f(x, y) is not a harmonic function, there is no corresponding analytic function.

Answer:

less than

Step-by-step explanation:

The standard deviation of set A is 0, and the standard deviation of B is about 1.8, so B is higher.

To do standard deviation, you first have to find the mean.

For B the mean is 7.

Then you subtract the mean from each number.

For B the data set is: -2, -2, 0, 2, 2

Then you square each number

4,4,0,4,4

Then you calculate the variance (basically the mean).

The mean of B is 3.2

Then you take the square root of 3.2, which is about 1.8.

If you do the same thing for A, you will get 0, which means set A is less than set B.

Answer:

Graphically.

Step-by-step explanation:

We have the equations:

(x + 6)^2 = -12*(y + 2)

(x^2/81) + (y^2/100) = 1

First, we can see that the second one is an ellipse, and we can write it as:

(x/9)^2 + (y/10)^2 = 1

This adds some complexity to our problem.

The first equation is just a quadratic equation, that we can write in standard form as:

y = (x^2 + 12*x + 36)/(-12) - 2

y = (-1/12)*x^2 - x - 5

Then our two equations are:

(x/9)^2 + (y/10)^2 = 1

y = (-1/12)*x^2 - x - 5

This is actually really hard to solve analytically, we may end with a quartic equation or something like that (this happens for the nature of the ellipse equation)

So now that we have two rather simple equations that we know how to graph (or that we can just input the equations in a program and graph them) we can find the intersections visually.

You can see the graph of this below:

Of course, this only works to find estimations for the intersections, where one intersection is (3.35, -9.28) and the other is at (-8.69, -2.6)

The circumference of a circle with a radius of 15 inches is 30π inches, or 94.25 inches

The circumference of a circle can be calculated using the formula:

C = 2πr

where C is the circumference, r is the radius, and π (pi) is a mathematical constant approximately equal to 3.14159.

In this case, the radius is 15 inches. Substituting this value into the formula, we get:

C = 2π(15) = 30π

So the circumference of a circle with a radius of 15 inches is 30π inches, or approximately 94.2478 inches.

The exact values of x that satisfy the equation 2cos(2x) + cos(x) - 1 = 0 within the range 0 < x < 2π are x = π/3 and x = 2π/3.

To solve the equation 2cos(2x) + cos(x) - 1 = 0, we can use some trigonometric identities and algebraic manipulations.

Let's rewrite the equation:

2cos(2x) + cos(x) - 1 = 0

To simplify the equation, we can use the double-angle formula for cosine:

cos(2x) = 2cos^2(x) - 1

Now, we can substitute cos(2x) in terms of cos(x) in the original equation:

2(2cos^2(x) - 1) + cos(x) - 1 = 0

Simplifying:

4cos^2(x) - 2 + cos(x) - 1 = 0

4cos^2(x) + cos(x) - 3 = 0

Now, let's solve this quadratic equation for cos(x):

Using factoring:

(4cos(x) - 1)(cos(x) + 3) = 0

Setting each factor equal to zero:

4cos(x) - 1 = 0 or cos(x) + 3 = 0

Solving the first equation:

4cos(x) = 1

cos(x) = 1/4

Solving the second equation:

cos(x) = -3 (not possible within the range 0 < x < 2π)

We focus on the first equation: cos(x) = 1/4

To find the exact values of x within the given range, we can use the inverse cosine function (arccos):

x = arccos(1/4)

Using the unit circle or a calculator, we find that arccos(1/4) = π/3 or 2π/3.

Therefore, the exact values of x that satisfy the equation 2cos(2x) + cos(x) - 1 = 0 within the range 0 < x < 2π are x = π/3 and x = 2π/3.

To determine the change in angular momentum (ΔL) of a cylinder from t = 0 to t = t0, a student can use the equation:

ΔL = I * Δω

where ΔL is the change in angular momentum, I is the moment of inertia of the cylinder, and Δω is the change in angular velocity.

To calculate Δω, the student needs to know the initial and final angular velocities, ω0 and ωt0, respectively. The change in angular velocity can be calculated as:

Δω = ωt0 - ω0

Once Δω is determined, the student can use the moment of inertia (I) of the cylinder to calculate ΔL using the equation mentioned earlier.

The moment of inertia (I) depends on the mass distribution and shape of the cylinder. For a solid cylinder rotating about its central axis, the moment of inertia is given by:

I = (1/2) * m * r^2

where m is the mass of the cylinder and r is the radius of the cylinder.

By substituting the known values for Δω and I into the equation ΔL = I * Δω, the student can calculate the change in angular momentum (ΔL) of the cylinder from t = 0 to t = t0.

It's important to note that this method assumes that no external torques act on the cylinder during the time interval. If there are external torques involved, the equation for ΔL would need to include those torques as well.

A neural network is a complicated set of possibly nonlinear equations. There are at least two degrees to a nonlinear equation.

This means that a variable in the equation can only be raised to the power of two or higher. A linear equation is typically represented as y = mx + c, where x and y are variables, m is the line's slope, and c is a constant. A nonlinear equation is one in which the highest degree of any term is two or greater.

The predicted value of y when x = 3, based on the least-squares regression line equation y = 50 - 15x, is y = 50 - 15(3) = 5.

The given least-squares regression line equation y = 50 - 15x represents a linear relationship between the variables x and y. In this equation, the coefficient of x (-15) represents the slope of the line, and the constant term (50) represents the y-intercept.

To find the predicted value of y when x = 3, we substitute x = 3 into the equation and solve for y. Plugging in x = 3, we have y = 50 - 15(3). Simplifying this expression, we get y = 50 - 45 = 5.

Therefore, when x = 3, the predicted value of y based on the least-squares regression line is 5. This means that according to the regression line, when x is 3, the expected or estimated value of y is 5.

Given, y = k√x

Let's find the following:

a. To find k, using the first pair given, (64, 16), plug in the values of the ordered pair into y = k√x

Thus:

16 = k√64

16 = k*8

Divide both sides by 8

16/8 = k

k = 2

b. To find F, substitute k = 2, and x = 100 into y = k√x

Thus:

y = 2√100

y = 2*10

y = 20

F = 20

c. To find x, substitute k = 2, and y = 10√2 into y = k√x.
