Step-by-step explanation:

The conditional PDF of X given Y = y is a geometric distribution with parameter 1-p.

Let X be a geometric random variable with parameter p, and let Y be a uniform random variable on the interval [0,1], which means the PDF of Y is fY(y) = 1 for 0 ≤ y ≤ 1 and 0 otherwise. We want to find the conditional PDF of X given Y = y.

By Bayes' theorem, the conditional PDF of X given Y = y is given by:

fX|Y(x|y) = fY|X(y|x) fX(x) / fY(y)

where fX(x) is the PDF of X, which is given by fX(x) = (1-p)^(x-1) p for x = 1, 2, 3, ..., and fY|X(y|x) is the PDF of Y given X = x, which is given by fY|X(y|x) = 1 for 0 ≤ y ≤ p and 0 otherwise.

To find fY(y), we use the law of total probability:

fY(y) = ∑ fX(x) fY|X(y|x) for all x

Plugging in the values of fX(x) and fY|X(y|x), we get:

fY(y) = ∑ (1-p)^(x-1) p for 0 ≤ y ≤ p and 0 otherwise.

Since Y is uniform on [0,1], we have fY(y) = 1 for 0 ≤ y ≤ 1 and 0 otherwise. Therefore, the above sum simplifies to:

∑ (1-p)^(x-1) p = p / (1 - (1-p)) = 1

Now we can plug in the values of fY(y) and fX(x|y) into the formula for the conditional PDF of X given Y = y:

fX|Y(x|y) = fY|X(y|x) fX(x) / fY(y)

fX|Y(x|y) = (1/p) (1-p)^(x-1) p / 1 = (1-p)^(x-1)

Thus, the conditional PDF of X given Y = y is a geometric distribution with parameter 1-p.

Answer:

1)0.0275

2)3.9×10^10

3)2×10^-6

4)did u mean 10^4?

if so then it would be 73,680

explanation

1)2.75×10^-2

2)39,000,000,000.00

in scientific notations the first number has to be lower than 10 and higher than 1>

3.9 works so i would take the dot/period and bring it between 3 and 9, the dot would travel 10 places therefore you raise the 10 to the 10th power

3.9×10^10

Answer:

cut the polygon into fourths.

since it's a square, the line values of each of the fourth's lines will equate.

find the area of one of the little triangles first.

area of triangle = 1/2 * a * b

area of triangle = 1/2 * 7 * 7 = 24.5

there're 4 triangles.

24.5*4 = 98

98 yds ^ 2

The area of your square is 98 yd²

The given information about the polygon is half of the diagonal length. Since 7 yds are only half of the diagonal length, we know to add another 7yds to complete the line. Therefore we have 14 as our diagonal length.

====================================

side length a = 9.8994949366117 yd

diagonal q = 14 yd

Therefore, visually interpreting histograms can be a powerful tool for data analysis, but it is important to be aware of their strengths and limitations.

Histograms are an effective way to display data graphically. They are used to show how often certain values or ranges of values appear in a data set. Visual interpretation of histograms has many strengths and limitations. Some of the strengths of visually interpreting histograms are that they are easy to read and understand, they provide a clear picture of how the data is distributed, and they can help identify outliers or gaps in the data. However, some of the limitations of visually interpreting histograms are that they can be influenced by the number of bins chosen, the way the data is grouped, and the choice of the scale used. Therefore, it is important to carefully consider these factors when interpreting a histogram. In conclusion, visually interpreting histograms can be a powerful tool for data analysis, but it is important to be aware of their strengths and limitations.

There are 127 marbles in the green box after he moved 55 of them to the red box, but before he combined the marbles in the blue and green boxes

Let's assume that the common ratio between the number of marbles in the red, blue, and green boxes is x.

Initially, the ratio of marbles in the three boxes is 12x: 13x: 15x.

After Vasil moves 25 marbles from the blue box to the red box, the new ratio becomes 12x : (13x - 25): 15x.

Similarly, after moving 55 marbles from the green box to the red box, the new ratio becomes (12x + 55) : (13x - 25) : (15x - 55).

Given that the combined number of marbles in the blue and green boxes matches the number of marbles in the red box, we have:

(13x - 25) + (15x - 55) = 12x + 55.

Simplifying the equation, we get:

28x - 80 = 12x + 55.

Subtracting 12x from both sides and adding 80 to both sides, we have:

16x = 135.

Dividing both sides by 16, we find:

x = 8.4375.

Since we need to determine the number of marbles in the green box before combining the marbles in the blue and green boxes, we substitute this value of x into the expression for the green box marbles: 15x.

15 * 8.4375 = 126.5625.

Rounding to the nearest whole number, we find that there were approximately 127 marbles in the green box after Vasil moved 55 of them to the red box, but before he combined the marbles in the blue and green boxes.

The values in b are compared with the true volume. And we conclude that b is precise and accurate.

Accuracy determines how closely measured values match the actual value. The degree to which two measured values are inside a certain range, or how closely they agree, is called precision.

First calculate the mean of a, b, and c. We get, the mean of a is 87.63, the mean of b is 87.06, and the mean of c is 87.77.

From the values in "a", we can tell there is no good agreement between the given values, and just one (87.1) value is near to the true value. So a is neither precise nor accurate.

From the values in "b", we can tell these given values are reasonably close to the true value and exhibit good agreement. So b is precise and accurate.

From the values in "c", we can tell there is a considerable agreement between the given values but they are not very close to the true value. So c is precise but not accurate.

(a) The best response functions for both players are:

Player 1's best response function: x = 1 - y

Player 2's best response function: y = 1 - x

(b) The Nash equilibrium of this game is when both players contribute half of the maximum possible contribution, which is 0.5.

To find the best response functions, we need to determine the strategies that maximize the payoffs for each player given the other player's strategy.

For Player 1, the payoff function is 2(x + y + xy) - x². To find the best response, we maximize this function with respect to x while assuming y is fixed. Taking the derivative of the payoff function with respect to x and setting it to zero, we get:

∂(2(x + y + xy) - x²)/∂x = 2 + 2y - 2x = 0

Simplifying this equation, we find:

2x = 2 + 2y

x = 1 + y

x = 1 - y (rearranging the equation)

This is the best response function for Player 1.

Similarly, for Player 2, the payoff function is 2(x + y + xy) - 2y². Maximizing this function with respect to y while assuming x is fixed, we differentiate and set it to zero:

∂(2(x + y + xy) - 2y²)/∂y = 2 + 2x - 4y = 0

Simplifying the equation, we find:

2y = 2 + 2x

y = 1 + x

y = 1 - x (rearranging the equation)

This is the best response function for Player 2.

To find the Nash equilibrium, we need to find the values of x and y where both best response functions intersect. Solving the simultaneous equations x = 1 - y and y = 1 - x, we find the Nash equilibrium point at x = y = 0.5.

The best response functions for both players in this game are Player 1's best response function: x = 1 - y and Player 2's best response function: y = 1 - x. The Nash equilibrium occurs when both players contribute half of the maximum possible contribution, which is x = y = 0.5.

The statement that "subset h of a vector space v is a subspace of v if the zero vector is in h" is true.

A subspace is a vector space that is also encompassed within another vector space.

So, while each subspace is a vector space in its own right, it is also defined with respect to another (bigger) vector space.

Three components must be demonstrated to prove that a subset is a subspace:

Additionally, demonstrate that it is closed.

Show that it is closed when scalar multiplication is used.

Show that vector 0 is a part of the subset.

As it is stated in the question;

h represents a subset of the vector space v.

The zero vector is contained in h.

This implies that h must be in the v subspace.

Hence, the statement that "subset h of a vector space v is a subspace of v if the zero vector is in h" is true.
