From the graph, we can see that:

V(x) have a positive value from x > 0 to x < 5.5

When x = 0 and ≥ 5.5, the values of V(x) are either 0 or negative

Hence, the reasonable domain of V(x) is 0 < x < 5.5

From the graph, the maximum value of V(x) is at

V(2) = 182

Hence, the approximate value of x that gives the maximum volume is 2

This is the interval where V(x) increase as x increase

From the graph, V(x) increase from x > 0 to x = 2

Hence, the approximate values of x where the volume increases are 0 < x ≤ 2

Step-by-step explanation:

Given that, 58% of the fish in a large pond are minnows. A simple random sample of 20 fish is scooped out and observed the sample proportion of minnows. We have to find the standard deviation of the sampling distribution.To find the standard deviation of the sampling distribution, we use the formula: σ = √[pq / n]

Whereσ is the standard deviation, p is the proportion of success, q is the proportion of failures, n is the sample size

We are given that, the proportion of minnows is 58%, then the proportion of other fishes (not minnows) will be (100 - 58)% = 42%.

So, p = 0.58 and q = 0.42. Also, the sample size is n = 20.Using the above values in the formula:σ = √[(0.58 × 0.42) / 20]= √0.01212= 0.11Therefore, the standard deviation of the sampling distribution is 0.11.

1.5 + 6 = 7.5

So, the sum of the solutions of the two equations is

B. 7 1/2

Answer:

Step-by-step explanation:

firstly we solve 8x=12 we divide both sides by 8 since 8 is the coefficient of x so we are trying to find x that is 8x divided by 8 which is x =12 divided by 8 which is 1.5 which means x=1.5 then we solve the second one 2y+10=22 we collect like terms which means 2y=22-10 as you should know the 10 changes to negative when crossed over to the other side so then 2y=12 is the answer then we divide both sides by the coefficient of y which is 2 so 2y divided by 2 =y 12 divided by 2 = 6 so y=6 then we add both of them together x=1.5+(y=6) so add 1.5 and 6 together answer is 7.5 or 7  1/2

X and Y be discrete random variables with joint probability function is answer is (D) 11/9.

To find E[Y| X = 1], we need to use the conditional expectation formula:

E[Y| X = 1] = Σy y P(Y = y| X = 1)

Using the joint probability function, we can find P(Y = y| X = 1):

P(Y = y| X = 1) = f(1, y) / Σy f(1, y)

P(Y = y| X = 1) = ((1/54)(1 + 1)(y + 2)) / ((1/54)(1 + 1)(0 + 2) + (1/54)(1 + 1)(1 + 2) + (1/54)(1 + 1)(2 + 2))

P(Y = y| X = 1) = (y + 2) / 9

Substituting this into the formula for \(E[Y| X = 1],\) we get:

E[Y| X = 1] = Σy y P(Y = y| X = 1)

E[Y| X = 1] = (0)(1/9) + (1)(3/9) + (2)(5/9)

E[Y| X = 1] = 11/9

The general relationship between the sample size and the margin of error is that they are inversely proportional.

As the sample size increases, the margin of error decreases, and vice versa. In other words, a larger sample size leads to a smaller margin of error, providing more accurate and reliable results. This occurs because larger samples are more likely to represent the entire population, reducing the chance of random sampling errors.

Conversely, a smaller sample size may not fully represent the population, leading to a higher margin of error and less accurate results. In conclusion, to obtain more precise and reliable findings, it's essential to choose an appropriate sample size that minimizes the margin of error while considering factors like population size, variability, and desired confidence level.

Answer:

y = -3x + 2

Step-by-step explanation:

To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2

Answer:

-3x+2=y

Step-by-step explanation:

u need to find the slope intercept formula which mx+b=y

m=slope

b=y-intercept

first u should find the slope which is y2-y1/x2-x1

point 1:(1,-1)

point 2:(3,-7)

-7+1/3-1=-6/2=-3

m=-3

now replace the variables

-3(1)+b=-1

-3 times 1=-3

-3+b=-1

add 3 to both sides

b=2

So, the measure of angle B is 90 degrees.

An angle is a geometric figure formed by two rays or line segments that share a common endpoint, called the vertex. The two rays or line segments are called the sides or arms of the angle. Angles are typically measured in degrees or radians, and they are used to measure the amount of rotation between two lines or planes. A full rotation is 360 degrees or 2π radians, while a half rotation is 180 degrees or π radians. Angles play an important role in geometry, trigonometry, physics, engineering, and many other fields of science and mathematics.

by the question.

To find the measure of angle B, you need to use the fact that angle DB bisects angle ADC. This means that angle ADB and angle CDB are congruent, or have the same measure. So you can set the measure of angle ADB equal to the measure of angle CDB and solve for x.

Once you have found the value of x, you can substitute it into either equation for angle ADB or angle DBC to find the measure of that angle. Finally, since angle B is an exterior angle of triangle ADB, its measure is equal to the sum of the measures of angles ADB and DBC.

So, the steps to find the measure of angle B are:

Set the measure of angle ADB equal to the measure of angle CDB:

(3x - 12) = (2x + 6)

Solve for x:

x = 18

Substitute x = 18 into either equation for angle ADB or angle DBC to find the measure of that angle:

angle ADB = (3x - 12) = (318 - 12) = 48 degrees

angle DBC = (2x + 6) = (218 + 6) = 42 degrees

Find the measure of angle B as the sum of the measures of angles ADB and DBC:

angle B = angle ADB + angle DBC = 48 + 42 = 90 degrees.

According to given information, answer is \(x = 2/3\).

The equation is \(16 * 4^{(x - 2)} = 64^{-2x}\).

Let's begin by simplifying both sides of the equation \(16 * 4^{(x - 2)} = 64^{-2x}\).

We can write \(64^{-2x}\) in terms of \(4^{(x - 2}\).

Observe that 64 is equal to \(4^3\).

So, we have \(64^{(-2x)} = (4^3)^{-2x} = 4^{-6x}\)

Hence, the given equation becomes \(16 * 4^{(x - 2)} = 4^{(-6x)}\)

Let's convert both sides of the equation into a common base and solve the resulting equation using the laws of exponents.

\(16 * 4^{(x - 2)} = 4^{(-6x)}\)

\(16 * 2^{(2(x - 2))} = 2^{(-6x)}\)

\(2^{(4 + 2x - 4)} = 2^{(-6x)}\)

\(2^{(2x)} = 2^{(-6x)}\)

\(2^{(2x + 6x)} = 12x\)

Answer:

The practice of using brass rings to stretch the neck, also known as neck elongation or neck stretching, is traditionally associated with the Padaung ethnic group from Myanmar (formerly known as Burma).

From a sociological perspective, the use of brass rings to stretch the neck can be seen as an example of deviance, which refers to behavior that violates social norms and expectations. Deviance can be either criminal or non-criminal, depending on the specific behavior in question and the cultural context in which it occurs.

In the case of Padaung women, the use of brass rings to elongate the neck is a form of non-criminal deviance, as it does not violate any laws. However, it does violate cultural norms and expectations in many other societies, where elongated necks are not seen as desirable or attractive.

Therefore, the practice of neck elongation among Padaung women can be seen as a form of cultural deviance, in which members of a particular group engage in behavior that is not considered acceptable or desirable by the larger society in which they live. At the same time, it can also be seen as an expression of cultural identity and tradition, as the practice has been passed down through generations and is an important part of Padaung culture and heritage.

The answer is that the resulting function is called a composite function.

A composite function is formed by combining two or more functions, where the output of one function becomes the input of another. In this case, when two functions are combined so that the range of one becomes the domain of the other, the resulting function is a composite function.

This can be given by considering two functions f(x) and g(x). If we want to create a composite function, we need to use the output of one function as the input for the other. So, if we let g(x) be the first function, then the output of g(x) becomes the input for f(x). This can be written as f(g(x)).

Now, if we want the range of g(x) to become the domain of f(x), we need to make sure that the output of g(x) is a valid input for f(x). In other words, the range of g(x) should be a subset of the domain of f(x).

For example, let's say g(x) = x² and f(x) =√(x). The domain of g(x) is all real numbers, and its range is all non-negative real numbers. The domain of f(x) is also all non-negative real numbers. So, we can create a composite function f(g(x)) by using the output of g(x) (which is always non-negative) as the input for f(x).
