The edge of the cube is equal to 2 m³.
QuadrilateralsThere are different quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, in a square, all angles are 90° and all sides present the same value.
A square is a 2D figure, when the square is associated with a 3D figure, the figure is called a cube.
The cube presents 6 faces with length (l), height (h) and width (w) equal. Thus, the cube presents congruent edges. The volume is given from the formula V=a³, where a is a congruent edge.
The exercise gives the volume of the cube 8m³. As presented previously, the edges of the cube are congruent and the formula by the volume is V=a³. Thus,
V=a³

Region Ris the base of solid. For the solid, each cross section perpendicular to the y-axis is rectangle whose height is twice the length of its base in region R: Find the volume of the solid.
the volume of the solid is x²/2R.
Let x be the length of the base of the rectangle.
The volume of the solid is given by:
V = ∫R 2x dx
= 2∫R x dx
= 2[x²/2]∫R dx
= x²/2 ∫R dx
= x²/2 (R - 0)
= x²/2 R
The volume of the solid is given by the integral of the cross sectional area of the solid. The cross sectional area is a rectangle whose base is x and the height is twice the length of the base. Therefore, the area of the cross section is 2x. The volume of the solid is calculated by integrating the area over the range of the variable, which in this case is R. The integral of 2x over the range R is 2x times R (2x*R). This can be simplified to x squared over two times R (x^2/2*R). Therefore, the volume of the solid is x squared over two times R.

Question At a sports event, a fair coin is flipped to determine which team has possession of the ball to start. The coin has two sides, heads, (H), and tails, (T). Identify the correct experiment, trial, and outcome below: Select all that apply: The experiment is identifying whether a heads or tails is flipped. The experiment is flipping the coin Atrial is flipping a heads. Atrial is one flip of the coin. An outcome is flipping a tails. An outcome is flipping a coin once.
The probability of flipping a heads or tails is the same, which is P(H or T) = 1.0.
The experiment of flipping a coin is an example of a binomial experiment as it has two possible outcomes, heads (H) or tails (T). The trial is the act of flipping the coin, and the outcome is the result of the flip, either heads or tails. The probability of flipping a heads is 50%, which can be expressed as a fraction: P(H) = 1/2, or a decimal: P(H) = 0.5. The probability of flipping a tails is also 50%, which can be expressed as P(T) = 1/2, or P(T) = 0.5. Therefore, the probability of flipping a heads or tails is the same, and this probability can be calculated as follows: P(H or T) = P(H) + P(T) = 0.5 + 0.5 = 1.0.

Problem 4. (Review from 420: Order statistics and independence) Let X be the minimum and Y the maximum of two random variables S and T with common continuous density f. Let Z denote the indicator function of the event (S
a) The distribution of Z is given by: P(Z = 1) = 1 - F(2T, T), P(Z = 0) = F(2T, T)
b) X and Z are not independent, Y and Z are not independent, and pair (X, Y) and Z are also not independent.
c) )X and Y are not independently existent.
a) The distribution of Z can be determined by finding the probability that S > 2T. Let F(s,t) be the joint cumulative distribution function of S and T. The probability that S > 2T is given by:
P(Z = 1) = P(S > 2T) = ∫∫_{2t < s} f(s,t) ds dt = 1 - F(2T, T)
Since T is nonnegative and has a continuous distribution, the cumulative distribution function F(2T, T) is also continuous and ranges from 0 to 1. Therefore, the distribution of Z is given by:
P(Z = 1) = 1 - F(2T, T), P(Z = 0) = F(2T, T)
b) X and Z are not independent, since the value of X affects the probability that S > 2T. For example, if X = x, then T >= x/2, so the value of Z depends on the value of X. Similarly, Y and Z are not independent, since the value of Y affects the probability that S > 2T. For example, if Y = y, then T <= y/2, so the value of Z depends on the value of Y.
The pair (X, Y) and Z are also not independent since the joint distribution of (X, Y) affects the probability that S > 2T. For example, if (X, Y) = (x, y), then T >= x/2 and T <= y/2, so the value of Z depends on the values of X and Y.
c) X and Y are not independent, since the value of X affects the value of Y. For example, if X = x, then Y >= x, so the value of Y depends on the value of X.

Use the shell method to set up and evaluate the integral that gives the volume of the solid generated by revolving the plane region about the y-axis. (Round your answer to three decimal places.) y = 1 2π e−x2/7 y = 0 x = 0 x = 1
The volume of the solid generated by revolving the region about the y-axis is approximately 0.200 cubic units.
To use the shell method to find the volume of the solid generated by revolving the region bounded by the curves [tex]$y=1$[/tex], [tex]$y=\frac{1}{2\pi e^{x^2/7}}$[/tex], [tex]$x=0$[/tex], and [tex]$x=1$[/tex] about the y-axis, we need to integrate along the x-axis.
The basic idea of the shell method is to take a vertical strip of width [tex]$dx$[/tex]and height [tex]$f(x)$[/tex] and revolve it about the y-axis to generate a thin shell of thickness [tex]$dx$[/tex] and radius x.
The volume of the solid is then given by the integral:
[tex]$$V = \int_{x=0}^{x=1} 2\pi x f(x) dx $$[/tex]
where [tex]$f(x)$[/tex] is the height of the shell at the position [tex]$x$[/tex]. In this case,
[tex]$f(x) =[/tex] [tex]1 - \frac{1}{2\pi e^{x^2/7}}$.[/tex]
So, we have:
[tex]$$V = \int_{x=0}^{x=1} 2\pi x \left(1 - \frac{1}{2\pi e^{x^2/7}}\right) dx $$[/tex]
Now, we can evaluate this integral using integration by substitution.
Let [tex]$u=x^2/7$[/tex], so [tex]$du/dx = 2x/7$[/tex] and [tex]$x,dx = 7/2,du$[/tex]. The integral becomes:
[tex]$$V = \int_{u=0}^{u=1/7} \frac{2\pi}{7} e^{-u} (7/2) du = \pi\int_{0}^{1/7} e^{-u} du$$[/tex]
Evaluating this integral gives:
[tex]$$V = \pi\left[-e^{-u}\right]_{0}^{1/7} = \pi\left(1 - e^{-1/7}\right) \approx \boxed{0.200}$$[/tex]
Therefore, the volume of the solid generated by revolving the region about the y-axis is approximately 0.200 cubic units.

The probability that X is between 17 and 27 is given as follows:
0.6826.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for this problem are given as follows:
[tex]\mu = 22, \sigma = 5[/tex]
The probability that X is between 17 and 27 is the p-value of Z when X = 27 subtracted by the p-value of Z when X = 17, hence:
Z = (27 - 22)/5
Z = 1
Z = 1 has a p-value of 0.8413.
Z = (17 - 22)/5
Z = -1
Z = -1 has a p-value of 0.1587.

Suppose that X is a random variable with mean 2 and variance 3. (a) Compute Var(2X + 1). (b) Compute E[(3X - 4) ^ 2]
From the given information provided, for random variable x, Var(2X + 1) = 12, E[(3X - 4²)] = 31.
A random variable is a variable whose value is subject to random variation, meaning that the outcome of an experiment or process is not deterministic, but rather is determined by chance.
(a) Using the properties of variance, we have:
Var(2X + 1) = Var(2X) = 4Var(X) = 4(3) = 12
(b) Using the linearity of expectation and the properties of variance, we have:
E[(3X - 4)²] = Var(3X - 4) + [E(3X - 4)]²
= Var(3X) + Var(-4) + [3E(X) - 4]²

What is -2x + 13 = -7X + 28
The red rectangle is the pre-image and the green rectangle is the image. What would be the coordinate of A" if the scale factor of 3 is used?
Pls show all your work!
Keep in mind I will immediately mark brainliest for the right answer!
Step-by-step explanation:
from red to green the scale factor was 2 (or rather 1/2).
so, it is not clear if a scale factor of 3 means now enlargement or again reduction ?
if it means reduction then
A'' = A'/3 = (-4, -2)/3 = (-4/3, -2/3)
if it is enlargement then
A'' = A'×3 = (-4, -2)×3 = (-12, -6)

sort the following list of functions in ascending order of growth rate and briefly explain why you put them in such order. for example, if f(n) appears before g(n) then f(n) = ___
The given list of functions can be arranged in ascending order of growth rate as follows: g1(n), g5(n), g3(n), g4(n), g2(n), g6(n), and g7(n).
The Big O notation describes the upper bound of a function's growth rate. In other words, it represents the maximum amount of time or space that a function requires to complete its operations.
Using this concept, we can arrange the given list of functions in ascending order of growth rate as follows:
g1(n) = √2 log n: This function has a growth rate of O(log n), which is less than the growth rates of all other functions in the list.
g5(n) = n log n: This function has a growth rate of O(n log n), which is greater than the growth rate of g1(n), but less than the growth rates of all other functions in the list.
g3(n) = n 4/3: This function has a growth rate of O(n 4/3), which is greater than the growth rates of g1(n) and g5(n), but less than the growth rates of all other functions in the list.
g4(n) = n(log n)3: This function has a growth rate of O(n(log n)3), which is greater than the growth rates of g1(n), g5(n), and g3(n), but less than the growth rates of all other functions in the list.
g2(n) = 2n: This function has a growth rate of O(2n), which is greater than the growth rates of g1(n), g5(n), g3(n), and g4(n), but less than the growth rates of g6(n) and g7(n).
g6(n) = 22 n: This function has a growth rate of O(2n), which is greater than the growth rates of g1(n), g5(n), g3(n), g4(n), and g2(n), but less than the growth rate of g7(n).
g7(n) = 2n2: This function has a growth rate of O(2n2), which is greater than the growth rates of all other functions in the list.
