Hope the below answer is easy to understand

Step-by-step explanation:

1)  Given the four angles of a quadrilateral are in the ratio 1:2:3:4

Then Let the angles are x,2x,3x and 4x

We know that total of  four angles of a quadrilateral =360 °

∴x+2x+3x+4x=360 °

⇒10x=360 °

⇒x=36  °

hence the measures of  angles are 36  ° ,72  ° ,108 °  ,144  °

2) Measure of interior angle of a polygon= 180°.

Sides of the polygon = 7 sides

Therefore,

Interior angle of the polygon having 7 sides = 180/7 = 25 5⁄7°

This relationship between AT-1 and A-I be used to determine information about matrix X by option (A) and (C).

(A) Since the two matrices are equal, the nonzero vector x must be a constant multiple of the nonzero vector v and (C) Since the two matrices are inverses, if either (AT-x=0 or (A-AI)v=0 has at least one nontrivial solution, then all of the statements of the Invertible Matrix Theorem are true for both matrices.

Therefore, if A is an eigenvalue of A, then λ must be an eigenvalue of AT, and vice versa. This can be seen by comparing the equation (A-λI)x=0 with the equation (AT-λI)v=0. If x is an eigenvector of A with eigenvalue λ, then it follows that v=x is an eigenvector of AT with eigenvalue λ. And if v is an eigenvector of AT with eigenvalue λ, then it follows that x=v is an eigenvector of A with eigenvalue λ.

The general solution of the system is: x = x (free parameter), y = (7/2)x, and z = -(3/2)x. This represents the set of all solutions to the system of equations.

To find the general solution of the system represented by the augmented matrix, we can perform row operations to bring the matrix to its reduced row-echelon form (RREF). The RREF will reveal the solution of the system.

Let's work through the row operations step by step:

Row 2 = Row 2 - 2 × Row 1

Row 3 = Row 3 - 4 × Row 1

The new augmented matrix after the first row operation:

[ 2 -7 3 0 ]

[ 0 0 0 0 ]

[ 0 0 0 0 ]

Next, divide Row 1 by 2:

Row 1 = Row 1 / 2

The updated augmented matrix:

[ 1 -7/2 3/2 0 ]

[ 0 0 0 0 ]

[ 0 0 0 0 ]

Now, we can see that the second and third rows consist of all zeros. This indicates that the system has infinitely many solutions.

To express the general solution, we can assign a parameter to one of the variables (let's choose x):

x = Free parameter

Then, we can express the other variables in terms of x:

y = (7/2)x

z = - (3/2)x

Therefore, the general solution of the system is:

x = x (free parameter)

y = (7/2)x

z = -(3/2)x

This represents the set of all solutions to the system of equations. By assigning different values to the parameter x, we can obtain infinitely many solutions.

Answer:

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

If it is an equilateral triangle the sides are equal

24-x = 5x

Add x to each side

24-x+x = 5x+x

24 =6x

Divide by 6

24/6 =6x/6

4 =x

Each side is 5x or 5*4 = 20

Add the 3 equal sides

20+20+20 = 60

The perimeter is 60

Answer:

60

Step-by-step explanation:

In this case, to find the perimeter, we need to know the value of at least one side.

Since this triangle is equilateral, \(5x=24-x\).

Adding x to both sides results in \(6x=24\), and subsequently, \(x=4.\)

Now that we know x equals 4, we can plug this into either 5x or 24-x and find out that one of the sides is 20.

Equilateral triangles have three equal sides, so 20 times 3, or 60, is the perimeter. I hope this helped!

Since triangle PQR is similar to triangle PTS

1) Side PQ is similar to side PT

2) Side QR is similar to side TS

3) side PR is similar to side PS

Standard Deviation statistic of the sampling distribution is used in calculating the margin of error for a confidence interval of the population mean.

Basically, the margin of error is stated as follows:

Error margin, E = Z* (Standard deviation)

Therefore, the calculation of the margin of error does not employ the mean at all.

The margin of error is computed using the standard deviation.

The term "standard deviation" reveals that a measurement of the data's dispersion from the mean. While a high standard deviation indicates that the data are more spread or dispersed, a low standard deviation suggests that the data are clustered or gathered around the mean.

It depicts the average deviation of each score from the mean. A high standard deviation in a normal distribution denotes that values are often far from the mean, while a low standard deviation denotes that values are grouped together around the mean.

Answer:

Evaluating the impact of the 16 Days of Activism campaign on Gender Based Violence (GBV) in South Africa requires a high-order analysis that considers various factors and perspectives. The campaign, which runs annually from November 25th (International Day for the Elimination of Violence against Women) to December 10th (International Human Rights Day), aims to raise awareness and mobilize action to prevent and respond to GBV.

The impact of the 16 Days of Activism campaign on GBV in South Africa can be evaluated through different lenses, including quantitative data, policy and legal changes, societal attitudes, and lived experiences of survivors.

Quantitatively, South Africa has one of the highest rates of GBV in the world, with statistics showing that one in five women in the country is a survivor of GBV. While there has been a slight decrease in the incidence of GBV in recent years, the numbers remain alarmingly high. It is difficult to attribute the reduction to the 16 Days of Activism campaign alone, as there are several other factors at play.

However, the campaign has contributed to policy and legal changes aimed at addressing GBV in South Africa. For instance, the Domestic Violence Act was amended in 2018 to include broader definitions of domestic violence and harsher penalties for perpetrators. In addition, the government has established various institutions and initiatives, such as the National Council Against Gender-Based Violence and the GBV Command Centre, to respond to GBV and provide support to survivors.

The 16 Days of Activism campaign has also had an impact on societal attitudes towards GBV in South Africa. Through awareness-raising activities, community dialogues, and media campaigns, the campaign has helped to break the silence and stigma around GBV, and encouraged more people to speak out and seek help. However, entrenched patriarchal norms and gender inequalities continue to fuel GBV in the country, and changing these attitudes requires sustained efforts beyond the 16 Days of Activism campaign.

Lastly, the impact of the 16 Days of Activism campaign on GBV in South Africa can be evaluated through the lived experiences of survivors. While the campaign has provided a platform for survivors to share their stories and advocate for change, many still face significant barriers in accessing justice and support. This includes systemic issues such as under-resourced police and healthcare systems, as well as cultural and social norms that blame and stigmatize survivors.

In conclusion, while the 16 Days of Activism campaign has had some impact on GBV in South Africa, it is clear that much more needs to be done to effectively address the root causes of this pervasive issue. The campaign serves as an important reminder of the urgent need for sustained and collaborative efforts from all sectors of society to prevent and respond to GBV.

The Laplace Transform of f(t) isL{f(t)} = L{t} + L{t + π}u(t − π) − L{t − 2π}u(t − 2π) + ...

                            = (1/s^2) + e^{−πs}(1/s^2) − e^{-2πs}(1/s^2) + ...= (1/s^2)[1 + e^{−πs} − e^{−2πs} + ...]

Given function is,f(t) ={ t, 0 < t < π π < t < 2π}

where f(t + 2 π) = f(t)

Let's take Laplace Transform of f(t)

                     L{f(t)} = L{t} + L{t + π}u(t − π) − L{t − 2π}u(t − 2π) + ...f(t + 2π) = f(t)

∴ L{f(t + 2 π)} = L{f(t)}⇒ e^{2πs}L{f(t)} = L{f(t)}

     ⇒ [e^{2πs} − 1]L{f(t)} = 0L{f(t)} = 0

when e^{2πs} ≠ 1 ⇒ s ≠ 0

∴ The Laplace Transform of f(t) is

                       L{f(t)} = L{t} + L{t + π}u(t − π) − L{t − 2π}u(t − 2π) + ...

The decision-maker is willing to pay a risk premium of $250 to eliminate the risk of lottery p', and a risk premium of $500 to eliminate the risk of lottery p?. Therefore, the decision-maker prefers lottery p?.

The decision-maker's utility function suggests that they have a logarithmic utility index, v(r) = In(2). To calculate the risk premia, we compare the expected utilities of the lotteries. For lottery p', the expected utility is E[v(p')] = (1/2) * v(-1000) + (1/2) * v(0) = (1/2) * In(2) + (1/2) * In(2) = In(2). For lottery p?, the expected utility is E[v(p?)] = v(-500) = In(2). Since both lotteries have the same expected utility, the decision-maker is indifferent between them in terms of expected utility.

However, the decision-maker is risk-averse, which means they prefer to eliminate risk when possible. To eliminate the risk of lottery p', the decision-maker is willing to pay a risk premium of $250 (which is half the difference between the potential losses of $1000 and $0). On the other hand, to eliminate the risk of lottery p?, the decision-maker is willing to pay a risk premium of $500 (the full potential loss amount).

Therefore, the decision-maker prefers lottery p? as they are willing to pay a higher risk premium to eliminate its risk.

Answer:

Step-by-step explanation:

In order to solve this problem, we can take it one step at a time. In this question, we can assume that Igli's starting point is 0. If on the first play he gained 3 yards that means we add this value to the starting point.

0 + 3 = 3 yards.

Now his current position is 3 yards. In the next play, he lost 9 yards which means we must subtract that from his current position.

3 - 9 = -6 yards

Now his current position is -6 yards. In order to get back to the initial position of 0 we need to add the opposite amount of yards as his current position. Since his current position is -6 we need to add positive 6 yards to get him back to 0.
