The proof is not valid, nor does it prove that 4 is equal to 3

This evidence is not true.

The error occurs in the step involving factoring, where both sides of the equation are divided by (a + b - c).

The problem is that if (a + b - c) equals zero, it is not permissible to divide both sides of the equation by (a + b - c) because it is not defined to be divided by zero

Moreover, even if (a + b - c) is not equal to zero, dividing both sides by (a + b - c) does not result in an equation

In this particular case, the fact that 4(a + b - c) = 3(a + b - c) implies that (a + b - c) = 0 or 4 = 3. One valid conclusion only if 4 = 3 is false.

a) 'they allow researchers to compare two competing models' is true of structural equation models.

a) They allow researchers to compare two competing models.

Structural equation modeling (SEM) is a statistical method used to analyze the relationships between multiple variables. It allows researchers to test and compare different models, including models with latent variables that are not directly observable. SEM can be used for both confirmatory and exploratory purposes, and it is a popular method in many fields, including social sciences, psychology, and business. Therefore, option (a) is true of structural equation models.

Option (b) is incorrect because SEM does not eliminate the third-variable problem in nonexperimental research. Rather, SEM allows researchers to control for and account for the effects of other variables in the model.

Option (c) is incorrect because structural equation models are not represented in a histogram. SEM involves constructing and testing a series of equations that represent the hypothesized relationships between variables.

Option (d) is also incorrect because SEM does not allow researchers to easily calculate the variance of a set of scores. SEM is used to test theoretical models and examine the relationships between variables, but it does not provide a direct measure of variance.

The solution to the system of equations is m = 6, n = 5.

To solve for the values of m and n in the given system of equations, we can use the method of substitution. We can solve one equation for one of the variables, for example, we can solve the second equation for n in terms of m: n = (28 - 3m) / 2. Then we can substitute this expression for n into the first equation and solve for m: 4m + 6[(28 - 3m)/2] = 54

Simplifying the equation by distributing the coefficient of 6, we get: 4m + 84 - 9m = 54. Combining like terms, we get: -5m = -30 ;

m = 6.

To find the value of n, we can substitute m = 6 into either equation and solve for n. Using the second equation, we have: 3(6) + 2n = 28. Simplifying, we get: 18 + 2n = 28 ; n = 5.

To solve the system of equations 4m + 6n = 54 and 3m + 2n = 28, we used the method of substitution to solve for one variable in terms of the other, then substituted the expression into the other equation to solve for the first variable. We substituted the value of the first variable into one of the original equations to solve for the second variable.

The Pythagorean theorem states that in a right triangle, [tex]a^2+b^2 = c^2[/tex] , where c is the hypotenuse, and a and b are the legs. So to use the Pythagorean theorem, we let [tex]a=x-3,b=x+4[/tex] and [tex]c=x+6[/tex]. Expanding everything gives [tex]2x^2+2x+25=x^2+12x+36[/tex]

Moving everything to one side tells us

[tex]x^2-10x-11=0[/tex]

So

[tex](x-11)(x+1)=0[/tex]

This means that either x = 11 or x = -1. But looking back at our equation, x = -1 is a false solution, because sides of a triangle could not be negative in length, and x-3 = -4 when x =-1. Therefore x = 11.

The weight of each men include the following:

B = 80 kilograms.

F = 95 kilograms.

In order to write a linear equation to describe this situation, we would assign variables to the weight of Fred and the weight of Barney respectively, and then translate the word problem into a linear equation as follows:

Since Fred weighs 15 kilograms more than Barney, a linear equation to describe this situation can be written as follows;

F = B + 15    ......equation 1.

Additionally, both Fred and Barney together weigh 175 kilograms;

F + B = 175      ......equation 2.

By substitution, we have:

B + 15 + B = 175

2B = 160

B = 80 kilograms.

F = B + 15

F = 80 + 15

F = 95 kilograms.

The measure of the angles which are supplementary to each are 103 and 77 degrees.

Supplementary angles sum up to 180 degrees.

Let the measure of the angle we're trying to find "x".

We know that this angle is 26 degrees more than its supplementary angle, which we can call "y".

So we can write:

x = y + 26

Since x and y are supplementary, their measures add up to 180 degrees:

x + y = 180

Now we can substitute the first equation into the second equation to eliminate "y":

(y + 26) + y = 180

2y + 26 = 180

Subtracting 26 from both sides:

2y = 154

Dividing both sides by 2:

y = 77

To find the other angle, we can use the first equation we wrote:

x = y + 26

Plug in y = 77

x = 77 + 26

x = 103

Therefore, the angles are 103 and 77 degrees.

By angle sum property of triangle, the correct option is Option D: A=130°, b=4, a=7.

A triangle is a three-sided polygon, which is a closed figure with three straight sides and three interior angles.

According to the given information:

The correct answer is Option D: A=130°, b=4, a=7.

In a triangle, the sum of the measures of the interior angles is always 180 degrees. Therefore, if one angle of a triangle is given, the other two angles can be determined by subtracting the given angle from 180 degrees.

In Options A, B, and C, the given angle A is less than 90 degrees, which means that the triangle would be acute, and there is a unique triangle that can be formed using the given data. The given sides b and a are also of appropriate lengths to form a triangle based on the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

However, in Option D, the given angle A is 130 degrees, which is greater than 90 degrees. This would result in an obtuse triangle, where one angle of the triangle is greater than 90 degrees. In this case, the given sides b=4 and a=7 may not be of appropriate lengths to form a triangle, as they may not satisfy the triangle inequality theorem.

The total area of the shaded portion is approximately 111.2 cm², given that a circle is inscribed in a square with a radius of 7 cm and an angle of 80 degrees, and the shaded area is a sector of the circle and a portion of the square.

To find the shaded area, we need to first find the area of the square and the area of the circle, and then subtract the area of the unshaded portion of the circle from the area of the square.

The diameter of the circle is equal to the side of the square, so the side of the square is 2 * 7 = 14 cm. Therefore, the area of the square is

Area of square = side² = 14² = 196 cm²

The area of the circle is

Area of circle = πr² = π(7)² = 49π cm²

The angle between the two radii of the circle that form the shaded sector is 80°, which is 80/360 = 2/9 of the total angle around the center of the circle. Therefore, the area of the shaded sector is

Area of shaded sector = (2/9)πr² = (2/9)π(7)² = 22.4π cm²

The unshaded area of the circle is the difference between the area of the circle and the area of the shaded sector

Unshaded area of circle = Area of circle - Area of shaded sector

= 49π - 22.4π

= 26.6π cm²

Finally, the area of the shaded portion is

Area of shaded portion = Area of square - Unshaded area of circle

= 196 - 26.6π

≈ 111.2 cm²

Therefore, the total area of the shaded portion is approximately 111.2 cm².
