Step-by-step explanation:

Answer:

First, it is important to remember the definition of Dilation.

A Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure, before the transformation) have the same shape, but their sizes are different.

In this case, you know that the triangle ABC is dilated by a scale factor of 2 with a center of dilation at the origin.

According to the exercise, point C has these coordinates:

c(2,1)

Therefore, in order to find the coordinates of C', you need to multiply the coordinates of point C by scale factor 2.

Then, you get that the coordinates of the point C' are:

c=(2*2,1*2)

c=(4,2)

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

Responder:

59 años

Explicación paso a paso:

Asumir que:

Edad actual = x

Edad 27 años atrás = x - 27

Edad dentro de 5 años = x + 5

La mitad de la edad de hace 27 años = 1/2 (x - 27)

Cuarto de edad dentro de cinco años = 1/4 (x +5)

0,5 (x - 27) = 0,25 (x + 5)

0.5x - 13.5 = 0.25x + 1.25

0.5x - 0.25x = 1.25 + 13.5

0,25 veces = 14,75

Dividir por 0,25

0,25x / 0,25 = 14,75 / 0,25

x = 59

Por lo tanto, la edad de Anahí ahora es de 59 años.

La edad actual de Anahí es de 59 años.

Sabemos por la pregunta que la mitad de la edad que tenía Anahí hace 27 años equivale a la cuarta parte de la edad que tendrá dentro de 5 años.

Para escribir esto como una ecuación, sea y la edad actual;

1/2(s - 27) = 1/4(y + 5)

El MCM de 2 y 4 es 4 por lo tanto;

4/2(y - 27) = 4/4(y + 5)

2(s - 27) =(y + 5)

2y - 54 = y + 5

2y -y = 5 + 54

y = 59

La edad actual de Anahí es de 59 años.

The perimeter of rectangle ABDC is 61.24 units.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The rectangle ABDC is given in the question which has:

AB = 8 and AC = 24

Here AC is the diagonal of the rectangle which is the hypotenuse in a right triangle.

As per Pythagoras's theorem,

AC² = AB² + BC²

24² = 8² + BC²

576 = 64 + BC²

BC² = 512

BC = 22.62

The perimeter of rectangle ABDC = 2(AB + BC)

The perimeter of rectangle ABDC = 2(8 + 22.62)

The perimeter of rectangle ABDC = 2(30.62)

Step-by-step explanation:

(a) The expected profit of this policy to the insurance company is $520.10.

(b) The interpretation value of expected profit in (a) in the context of the problem is small probability of the policyholder's death.

(a) The expected profit to the insurance company can be calculated as follows:

Expected Profit = (Probability of Survival * Premium) - (Probability of Death * Death Benefit)

Probability of Survival = 0.997

Probability of Death = 1 - Probability of Survival = 1 - 0.997 = 0.003

Premium = $780

Death Benefit = $250,000

Expected Profit = (0.997 * $780) - (0.003 * $250,000) = $520.10

Therefore, the expected profit to the insurance company from selling this policy is $520.10.

(b) The expected profit of $520.10 represents the average profit that the insurance company can expect to earn from selling this type of policy to similar customers over time.

In the context of this problem, it means that if the insurance company sells many policies like this one, they can expect to make a profit of about $520.10 per policy, on average, after accounting for the small probability of the policyholder's death.

Answer: Two planes intersecting in a line

Explanation:

The wall and floor are two different planes. They meet up to form a line which is the crease between them.

A plane is a flat surface without any bends or curves to it. In theoretical terms, planes go on forever in all directions. Realistically there are limits of course. The wall or floor cannot go on forever.

Another example of two planes would be found in a book. Each page is a plane. Two adjacent pages meet up to form a line (i.e. the spine of the book is a line).

I may utilize the Cp Criterion, AICp, and SBCp to aid in choosing the optimal model. All of them impose sanctions for introducing predictions.

Best subsets regression is a model-building regression analysis that is exploratory. It compares every model that might be built using a specified set of predictors. Best subset selection is a technique that looks at all potential combinations of independent variables in order to identify the subset of independent variables (Xi) that best predicts the result (Y). Finding a small subset of predictors is the goal of best-subset selection in order for the final linear model to have the most ideal prediction accuracy.

No, 3 is not a factor of 26.

In mathematics, a factor is an integer that divides another integer exactly without leaving any remainder. When an integer "A" is a factor of an integer "B", we say "A" is a factor of "B" or "A divides B" or "B is divisible by A".

To determine if 3 is a factor of 26, we need to see if 26 can be divided exactly by 3. We can do this by dividing 26 by 3 and checking the remainder.

26 ÷ 3 = 8 with a remainder of 2

Since the result of the division is not an integer, meaning there is a remainder of 2, this means that 3 is not a factor of 26. Therefore, we can conclude that 3 is not a factor of 26.

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:

tan(ACD) = CE / AB

tan(19) = CE / 100

CE = 100 * tan(19)

CE ≈ 34.5 m (rounded to 1 decimal place)

Therefore, the height of the clock tower is approximately 34.5 m.

There are a total of 12 chocolate chip + 10 sugar + 18 peanut butter = 40 cookies in the sack. The probability of selecting a cookie that is not a peanut butter cookie is (12 chocolate chip + 10 sugar) / 40 = 22/40 or 0.55. So, there is a 55% chance that the selected cookie will not be a peanut butter cookie.

With the Test at 5% level of significance, we reject the null hypothesis and conclude that the given sample cannot be reasonably regarded as a sample from a large population of cars with mean weight 1500 kg and standard deviation 130 kg.

We have B = 921

Therefore, mean of the sample = (1000 + 921) kg = 1921 kg

Population mean µ = 1500 kg

Population standard deviation σ = 130 kg

We need to test whether the sample is from the given population or not. For this, we use the z-test statistic.z = (x - µ) / (σ / sqrt(n))

Where,x = sample mean

µ = population mean

σ = population standard deviation

n = sample sizez = test statistic

Using the given values,

z = (1921 - 1500) / (130 / √(500))

z = 35.2633

Since the sample size is greater than 30, we can use the normal distribution table.

Using the normal distribution table, we find that the area to the right of z = 35.2633 is zero.

Therefore, the probability of the sample being from the given population is zero.Hence, we reject the null hypothesis and conclude that the given sample cannot be reasonably regarded as a sample from a large population of cars with mean weight 1500 kg and standard deviation 130 kg.

The gradient vector field ∇f of the function f(x, y, z) = 5x^2y^2z^2 can be found by taking the partial derivatives of f with respect to each variable (x, y, z). The summary of the answer is that the gradient vector field ∇f is given by ∇f = (10xy^2z^2, 10x^2yz^2, 10x^2y^2z).

The gradient vector of a scalar function is a vector that points in the direction of the steepest increase of the function at each point. It is obtained by taking the partial derivatives of the function with respect to each variable.

To find the gradient vector field ∇f of f(x, y, z) = 5x^2y^2z^2, we compute the partial derivatives of f with respect to x, y, and z.

∂f/∂x = 10xy^2z^2

∂f/∂y = 10x^2yz^2

∂f/∂z = 10x^2y^2z

Combining these partial derivatives, we get the gradient vector field ∇f = (10xy^2z^2, 10x^2yz^2, 10x^2y^2z).

Each component of the gradient vector field represents the rate of change of the function f in the corresponding direction. For example, the first component 10xy^2z^2 indicates that the function f increases at a rate of 10xy^2z^2 in the x-direction, and so on for the other components.

Therefore, the gradient vector field ∇f of f(x, y, z) = 5x^2y^2z^2 is given by ∇f = (10xy^2z^2, 10x^2yz^2, 10x^2y^2z).
