To summarize, a perfectly egalitarian society has a Gini index of 0, and a perfectly totalitarian society has a Gini index of 1.

The Gini index (G) measures how much the income distribution differs from absolute equality.

On the other hand, a perfectly totalitarian society (where a single person receives all the income) will have a Gini index of 1. This means that there is a huge inequality between individuals, with the single person receiving all of the income.

\(\huge\boxed{\sf 11.74\ in.\²}\)

Step-by-step explanation:

Area of Rectangle:

Length = 11.8 in.

Width = 3.6 in.

Area = Length * Width

Area = 11.8 * 3.6

Area = 42.48 in.²

Area of 3 circles:

Diameter = 3.6 in.

Radius = D/2 = 3.6/2 = 1.8 in.

\(\sf Area = \pi r^2\\\\Area = (3.14)(1.8)^2\\\\Area = (3.14)(3.24)\\\\Area = 10.18\ in.^2\)

Area of 3 circles = 3(10.18) = 30.5 in.²

Area of the figure when the 3 circles are cut:

= Area of the rectangle - Area of 3 circles

The generator matrix is  \(\left[\begin{array}{cccccc}1&0&0&1&1&0\\0&1&0&1&0&1\\0&0&1&0&1&1\end{array}\right]\)  and the parity-check matrix is  \(\left[\begin{array}{cccccc}-1&-1&-1&1&0&0\\-1&-1&0&0&1&0\\0&-1&-1&0&0&1\end{array}\right]\)  .

To find the generator matrix and parity-check matrix for the given systematic (7,4) code, we can use the given parity-check equations.

The generator matrix G for a systematic code is constructed by placing the message bits u0​, u1​, u2​ in the first three columns and adding parity bits v0​, v1​, v2​ as the remaining columns.

The parity-check matrix H is formed by taking the coefficients of the parity-check equations and negating them.

Given parity-check equations:

v0​ = u0​ + u2​ + u3​

v1​ = u0​ + u1​ + u2​

v2​ = u1​ + u2​ + u3​

From these equations, we can write the generator matrix G:

G = [u0​ u1​ u2​ | v0​ v1​ v2​]

G = \(\left[\begin{array}{cccccc}1&0&0&1&1&0\\0&1&0&1&0&1\\0&0&1&0&1&1\end{array}\right]\)

This is the generator matrix for the given systematic code.

To obtain the parity-check matrix H, we take the coefficients of the parity-check equations and negate them:

H =\(\left[\begin{array}{cccccc}-1&-1&-1&1&0&0\\-1&-1&0&0&1&0\\0&-1&-1&0&0&1\end{array}\right]\)

This is the parity-check matrix for the given systematic code.

Therefore, the generator matrix G is:

G = \(\left[\begin{array}{cccccc}1&0&0&1&1&0\\0&1&0&1&0&1\\0&0&1&0&1&1\end{array}\right]\)

And the parity-check matrix H is:

H = \(\left[\begin{array}{cccccc}-1&-1&-1&1&0&0\\-1&-1&0&0&1&0\\0&-1&-1&0&0&1\end{array}\right]\)

The given system of equations does not have a solution as there are no values of a, b, and c that allow the given system of equations to have a solution.

To determine the values of the constants a, b, and c that allow the given system of equations to have a solution, we need to examine the system and check for consistency and dependence.

The system of equations is as follows:

x + 2y + z = a

-y + z = -2a

2 + 3y + 2z = b

3r - y + z = c

To find the values of a, b, and c that satisfy the system, we can perform operations on the equations to simplify and compare them.

Starting with equation 2, we can rewrite it as y - z = 2a.

Comparing equation 1 and equation 3, we notice that the coefficients of y and z are different.

In order for the system to have a solution, the coefficients of y and z in both equations should be proportional.

Therefore, we need to find values of a, b, and c such that the ratios between the coefficients in equation 1 and equation 3 are equal.

From equation 1, the ratio of the coefficient of y to the coefficient of z is 2.

From equation 3, the ratio of the coefficient of y to the coefficient of z is 3/2. Setting these ratios equal, we have:

2 = 3/2

4 = 3

Since the ratio is not equal, there are no values of a, b, and c that satisfy the system of equations.

Therefore, the system does not have a solution.

In summary, there are no values of a, b, and c that allow the given system of equations to have a solution.

Answer: The answer is B) y < 0

Answer: B

Step-by-step explanation:

The counterclockwise circulation around c is 12 and the outward flux through c is zero.

Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.

In this case,

we have a field f=(7x−4y)i+(9y−4x)j and

a square curve c bounded by x=0, x=4, y=0, y=4.

To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.

The curl of f is given by (0,0,3), so the line integral evaluates to 12.

To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.

Answer:

x = 25

Step-by-step explanation:

3x + 5 + 5x - 25 = 180 (collect like terms)

8x - 20 = 180 (add 20 on both sides)

8x = 200 (divide by 8 on both sides)

x = 25

Since they are supplementary that mean together they add up to 180 so that's why I added them together.

The tangential and normal components of the acceleration when s = 10 m is 40 m/s^2 and 8 m/s^2 respectively.

In the given question, a car is travelling along the road with a speed of 2s m/s, where s is in meters.

We have to determine the tangential and normal components of the acceleration when s = 10 m.

Speed (v) = 2s  

Motion is circular so, Radius of circle = 50m

Tangential acceleration = dv/dt

Tangential acceleration = d(2s) / dt

Tangential acceleration = 2(ds)/dt

Tangential acceleration = 2v

Tangential acceleration = 2(2s)

Tangential Acceleration = 4s

As given s = 10 m

Tangential acceleration = 4 x 10

Tangential acceleration  = 40 m/s^2

Normal acceleration = v^2/ r

Normal acceleration = 4s^2/r

Normal acceleration = {4 x 10^2}/50

Normal acceleration = {4 x 100}/50

Normal acceleration = 400/50

Normal acceleration = 8 m/s^2

In long division, 63.92/9.4 results with quotient of 6.8.

Long division is a method of dividing two numbers by repeatedly subtracting the divisor from the dividend and keeping track of the resulting quotient and remainder. This method is often used when dividing two numbers with several digits. The process of long division involves several steps that are repeated until there is no remainder left or until a desired level of precision is achieved.

In long division, the dividend is the number being divided, and the divisor is the number by which the dividend is being divided. The quotient is the result of the division, and the remainder is the amount left over after the division is complete.

It will take Rob and Tricia 75 minutes to paint 2/3 of the room together. Rob can paint 1/3 of the room in 2 hours, and Tricia can paint 1/2 of the room in 5 hours.

To determine how quickly they can paint the room together, we'll first find their individual painting rates.

Rob's rate: (1/3 room) / (2 hours) = 1/6 room/hour
Tricia's rate: (1/2 room) / (5 hours) = 1/10 room/hour

Now, we'll add their rates together to find their combined rate:
(1/6 + 1/10) room/hour = (5/30 + 3/30) room/hour = 8/30 room/hour

Next, we need to find how long it takes for them to paint 2/3 of the room together:
(2/3 room) / (8/30 room/hour) = (2/3) * (30/8) hours = 5/4 hours

Finally, convert this time to minutes:

The conclusion that Catherine must have just eaten because she took aspirin is an example of inductive reasoning.

Inductive reasoning involves drawing general conclusions based on specific observations or evidence. In this case, the specific observation is that Catherine took aspirin, and the general conclusion is that she must have just eaten.

Inductive reasoning relies on the idea that if a specific observation or evidence is consistently true, then a general conclusion can be inferred. However, it does not guarantee certainty. While it is likely that Catherine took aspirin after eating, there is still a possibility that she took it without eating, making the conclusion probabilistic rather than definitive.

Inductive reasoning is commonly used in everyday life to make predictions, form hypotheses, or draw general conclusions based on limited information or past experiences. It helps to make reasonable assumptions, but it is important to recognize its limitations and the possibility of alternative explanations.

The thickness of the tharsan thir is approximately 0.06 mm when expressed in two decimal places.

To convert micrometers (μm) to millimeters (mm), we need to divide the value in micrometers by 1000 since there are 1000 micrometers in a millimeter.

Given that the thickness is 60 μm, we can perform the conversion as follows:

60 μm / 1000 = 0.06 mm

Therefore, the thickness of the tharsan thir is approximately 0.06 mm when expressed in two decimal places.

Millimeters and micrometers are both units of length, with millimeters being the larger unit. Micrometers are often used to represent very small measurements, such as the thickness of thin materials or microscopic objects. In this case, the tharsan thir has a thickness of 60 micrometers, which is equivalent to 0.06 millimeters.

The two-phase method is used to solve linear programming problems with constraints in standard form. Let's apply the two-phase method to solve the given LPP: Phase 1: Introduce artificial variables to convert the inequality constraint into equality. The modified problem becomes: minimize w = A₁ + A₂; subject to: 2x₁ + x₂ + x₃ + A₁ = 2; 3x₁ + 4x₂ + 2x₃ - A₂ = 8; x₁, x₂, x₃, A₁, A₂ ≥ 0. Phase 2: Using the simplex method, solve the Phase 1 problem to obtain an initial basic feasible solution. Perform iterations until we reach an optimal solution. The optimal solution of the Phase 1 problem is w = 0, x₁ = 2/3, x₂ = 0, x₃ = 4/3, A₁ = 0, A₂ = 0. Phase 2: Now, remove the artificial variables and the objective coefficient of w. We are left with the original problem: maximize z = 3x₁ + 2x₂ + 3x₃. subject to: 2x₁ + x₂ + x₃ ≤ 2; 3x₁ + 4x₂ + 2x₃ ≥ 8; x₁, x₂, x₃ ≥ 0.

Using the simplex method, solve the Phase 2 problem starting from the basic feasible solution obtained in Phase 1. Perform iterations until we reach the optimal solution. The final optimal solution is z = 16/3, x₁ = 4/3, x₂ = 2/3, x₃ = 0. Therefore, the maximum value of the objective function z is 16/3, and the values of x₁, x₂, and x₃ corresponding to this maximum are 4/3, 2/3, and 0, respectively.
