Answer:

GB = 7

BE = 10.5

AG = 10

DG = 5

FG = 3·x

CF = 9·x

Step-by-step explanation:

The given parameters are;

The centroid of the ΔABC = G

Segments CF, BE, and AD are median lines

EG = 3.5 Given

∴ EG = 1/3 × BE by definition of the properties of median line

∴ BE = 3 × EG = 3 × 3.5 = 10.5

BE = 10.5

GB = 2/3 × BE = 2/3 × 10.5 = 7 by definition of the properties of median line BE

GB = 7

Similarly;

Given that AD = 15, AG = 2/3 × AD = 2/3 × 15 = 10 by definition of the properties of median line AD

AD = 10

DG = 1/3 × AD = 1/3 × 15 = 5 by definition of the properties of median line AD

DG = 5

Similarly;

Given  CG = 6·x

FG = 1/3 × CF

CF = 3 × FG

CG = 2/3 × CF = 2/3 × 3 × FG

∴ CG = 2 × FG

FG = CG/2 = 6·x/

2 = 3·x

FG = 3·x

CF = 3 × FG = CF = 3 × 3 × x = 9·x

CF = 9·x

Step-by-step explanation:

The verdict which is true about the radius of all three arcs when constructing an angle bisector is; - No; the second two arcs must have the same radius but it can be different from the first.

The correct answer option is option C.

Recall that an angle at point, O is formed by the intersection of two lines; say lines A and B.

Hence, in a bid to draw the Angie bisector of the angle; AOB, three arcs are needed.

The first arc is an arc drawn by placing the pivot of the compass at the point, O and drawing an arc which intersects lines A and B. The radius of this first arc in discuss can be any value.

Subsequently, the other two arcs are propagated using the points of intersection of the first arc with both lines such that the two arcs intersect.

To find the joint density function, we need to calculate the Jacobian determinant of the transformation from (x, y) to (u, v)

The joint distribution of (u, v), where u and v are defined as

\(u = \frac{x}{{\sqrt{x^2 + y^2}}}\)  and \(v = \frac{y}{{\sqrt{x^2 + y^2}}}\), is given by:

\(f_{U,V}(u,v) = \frac{1}{{2\pi}} \cdot e^{-\frac{1}{2}(u^2 + v^2)}\)

To find the joint density function, we need to calculate the Jacobian determinant of the transformation from (x, y) to (u, v):

\(J = \frac{{du}}{{dx}} \frac{{du}}{{dy}}\)

\(\frac{{dv}}{{dx}} \frac{{dv}}{{dy}}\)

Substituting u and v in terms of x and y, we can evaluate the partial derivatives:

\(\frac{{du}}{{dx}} &= \frac{{y}}{{(x^2 + y^2)^{3/2}}} \\\frac{{du}}{{dy}} &= -\frac{{x}}{{(x^2 + y^2)^{3/2}}} \\\frac{{dv}}{{dx}} &= -\frac{{x}}{{(x^2 + y^2)^{3/2}}} \\\frac{{dv}}{{dy}} &= \frac{{y}}{{(x^2 + y^2)^{3/2}}}\)

Therefore, the Jacobian determinant is:

\(J &= \frac{y}{{(x^2 + y^2)^{\frac{3}{2}}}} - \frac{x}{{(x^2 + y^2)^{\frac{3}{2}}}} \\&= -\frac{x}{{(x^2 + y^2)^{\frac{3}{2}}}} + \frac{y}{{(x^2 + y^2)^{\frac{3}{2}}}} \\J &= \frac{1}{{(x^2 + y^2)^{\frac{1}{2}}}}\)

Now, we can find the joint density function of (u, v) as follows:

\(f_{U,V}(u,v) &= f_{X,Y}(x,y) \cdot \left|\frac{{dx,dy}}{{du,dv}}\right| \\&= f_{X,Y}(x,y) / J \\&= f_{X,Y}(x,y) \cdot (x^2 + y^2)^{\frac{1}{2}}\)

Substituting the standard normal density function

\(f_{X,Y}(x,y) &= \frac{1}{2\pi} \cdot e^{-\frac{1}{2}(x^2 + y^2)} \\f_{U,V}(u,v) &= \frac{1}{2\pi} \cdot e^{-\frac{1}{2}(x^2 + y^2)} \cdot (x^2 + y^2)^{\frac{1}{2}} \\&= \frac{1}{2\pi} \cdot e^{-\frac{1}{2}(u^2 + v^2)}\)

Therefore, the joint distribution of (u, v) is given by:

\(f_{U,V}(u,v) &= \frac{1}{2\pi} \cdot \exp\left(-\frac{1}{2}(u^2 + v^2)\right)\)

To find the joint density function, we need to calculate the Jacobian determinant of the transformation from (x, y) to (u, v)

The joint distribution of (u, v) is a bivariate normal distribution with mean (0,0) and variance-covariance matrix

\(\begin{bmatrix}2 & 0 \0 & 2\end{bmatrix}\)

The joint distribution of (u, v) can be found by transforming the independent random variables x and y using the following formulas:

\( u = x + y\)
\( v = x - y \)

To find the joint distribution of (u, v), we need to find the joint probability density function (pdf) of u and v.

Let's start by finding the Jacobian determinant of the transformation:

\(J = \frac{{\partial (x, y)}}{{\partial (u, v)}}\)

\(= \frac{{\partial x}}{{\partial u}} \cdot \frac{{\partial y}}{{\partial v}} - \frac{{\partial x}}{{\partial v}} \cdot \frac{{\partial y}}{{\partial u}}\)

\(= \left(\frac{1}{2}\right) \cdot \left(-\frac{1}{2}\right) - \left(\frac{1}{2}\right) \cdot \left(\frac{1}{2}\right)\)

\(J = -\frac{1}{2}\)

Next, we need to express x and y in terms of u and v:

\(x = \frac{u + v}{2}\)

\(y = \frac{u - v}{2}\)

Now, we can find the joint pdf of u and v by substituting the expressions for x and y into the joint pdf of x and y:

\(f(u, v) = f(x, y) \cdot |J|\)

\(f(u, v) = \left(\frac{1}{\sqrt{2\pi}}\right) \cdot \exp\left(-\frac{x^2}{2}\right) \cdot \left(\frac{1}{\sqrt{2\pi}}\right) \cdot \exp\left(-\frac{y^2}{2}\right) \cdot \left|-\frac{1}{2}\right|\)

\(f(u, v) = \frac{1}{2\pi} \cdot \exp\left(-\frac{u^2 + v^2}{8}\right)\)

Therefore, the joint distribution of (u, v) is given by:

\(f(u, v) = \frac{1}{2\pi} \cdot \exp\left(-\frac{{u^2 + v^2}}{8}\right)\)

In summary, the joint distribution of (u, v) is a bivariate normal distribution with mean (0,0) and variance-covariance matrix

Answer:

  (π+2)/(π-1)

Step-by-step explanation:

The sum of an infinite geometric series with first term 'a' and common ratio 'r' is given by the formula ...

  S = a/(1 -r) . . . . . for |r| < 1

The given sum can be decomposed into a constant and a series:

  = -2 +(3 +3/π +3/π² +3/π³ +...)

  = -2 +S . . . where a=3 and r=1/π in the above sum formula

Then the sum is ...

  \(-2+\dfrac{3}{1-\dfrac{1}{\pi}}=-2+\dfrac{3\pi}{\pi-1}=\dfrac{-2(\pi-1)+3\pi}{\pi-1}=\boxed{\dfrac{\pi+2}{\pi-1}}\)

Additional comment

There is no way to rationalize the denominator of this fraction, but the numerator can be rationalized by writing it as a mixed number:

  \(=\dfrac{3}{\pi-1}+1\)

Effectively, this is the same as we would have gotten with ...

  1 +S . . . where a=3/π and r=1/π

The value of x is 17.

Supplementary angles are two angles that add up to 180 degrees. In this case, we know that angle F and angle H are supplementary angles. We also know that the measure of angle F is 77 degrees and the measure of angle H is 5x + 18 degrees.

So we can write the following equation to represent the fact that the sum of the measures of these two angles is 180 degrees:

77 + 5x + 18 = 180

Simplifying this equation, we get:

5x + 95 = 180

Subtracting 95 from both sides, we get:

5x = 85

Dividing both sides by 5, we get:

x = 17

Therefore, the value of x is 17.

The antiderivatives of dy/dx = x - e^x are y = 1/2 x^2 - e^x + C, where C is an arbitrary constant.

To find the antiderivatives of dy/dx = x - e^x, we need to integrate both sides with respect to x.

∫dy = ∫(x - e^x)dx

Integrating the right side using the sum rule of integration, we get:

y = 1/2 x^2 - ∫e^x dx

Using the power rule of integration, we can integrate e^x, which gives us:

y = 1/2 x^2 - e^x + C

where C is an arbitrary constant of integration.

Therefore, the antiderivatives of dy/dx = x - e^x are y = 1/2 x^2 - e^x + C, where C is an arbitrary constant.

Answer:

30 Gallons

Step-by-step explanation:

Okay so you need to start by making an equation for yourself. Since the container starts at 1/10 of the total, you want to start by saying 1/10x. Then you add 12 gallons of water to make it half full. So 1/10x + 12 = 1/2x where x is the total amount that can fit in the container.

1/10x + 12 = 1/2x (Move your x's to the same side.)

12 = 1/2x - 1/10x (Find a common denominator.)

12 = 5/10x - 1/10x (Simplify/)

12 = 4/10x (Multiply both sides by 10; your demoninator)

120 = 4x (Divide)

x = 30

Your container holds 30 gallons.

The sampling method used in the given study is stratified sampling. In this method, the population is divided into homogeneous groups called strata, and a random sample is selected from each stratum to form the final sample. stratified sampling is a useful method for selecting a representative sample from a heterogeneous population when subgroups are well defined.

The given study chooses the sample by dividing the population by voting district and sampling everyone in five districts selected. Therefore, it is an example of stratified sampling where the strata are defined by voting districts. The method is preferred when the population is heterogeneous and it is important to ensure that the sample represents all subgroups of the population.

By dividing the population into strata, the variability within each stratum is reduced, making the sample more representative of the entire population.

In the given study, stratified sampling was used because the researchers wanted to ensure that the sample represents the entire population by selecting individuals from different voting districts. By dividing the population into strata based on voting districts, the researchers were able to reduce the variability within each stratum, making the sample more representative of the entire population.

In addition, the method also ensures that each stratum is represented in the sample, providing a more accurate estimate of the population parameters.
