"When written in reduced echelon​ form, any m×n matrix will have at least one row of all zeros. When solving Ax=b​, that row will represent an equation with a zero on the left side and a possibly nonzero entry of b on the right side."

Now, According to the question:

"Information available from the question"

Let a be a 3 x 2 matrix. explain why the equation a x b cannot be consistent for all b in.

Since a 3x2 matrix only has 2 columns, matrix A can at most have 2 pivot columns and 2 pivot positions. This cannot fill all 3 rows w/ pivots so Ax=b can't be consistent for all b in R3. If A is an m x n matrix w/ m>n then A can have at most n pivot positions which isn't enough to fill all m rows, so Ax = b can't be consistent for all b in R3.

Hence, The correct option is (A)

Step-by-step explanation:

The diagonals of a parallelogram are equal in length if and only if the parallelogram is a rectangle. The sum of squares of diagonals is equal to the sum of squares of sides.

We should consider a parallelogram shape that has sides named as and .

a. The corner to corner lines of the parallelogram can be marked as and . These two inclining lines cross each other at the focal point of the parallelogram, isolating each other into halves. This implies that the two inclining lines and have a similar length.

b. Assuming the inclining lines of the parallelogram have similar length, this implies that the parallelogram is really a square shape. This is on the grounds that in a square shape, every one of the sides are equivalent long. Then again, on the off chance that the parallelogram is a square shape, its inclining lines should have a similar length.

c. We can utilize the Pythagorean hypothesis to show that the amount of the squares of the lengths of the slanting lines is equivalent to the amount of the squares of the lengths of the sides. The Pythagorean hypothesis expresses that in a right triangle, the amount of the squares of the two more limited sides is equivalent to the square of the length of the longest side (the hypotenuse). On the off chance that we view at the parallelogram as two nearby right triangles, we can apply the Pythagorean hypothesis to every triangle. This gives us two conditions, and when we add these two conditions, we observe that the amount of the squares of the lengths of the inclining lines is equivalent to the amount of the squares of the lengths of the sides.

The values that make vector b a linear combination of vectors A1, A2 and A3 are given as follows:

[tex]\alpha_1 = -1.9, \alpha_2 = 1.1, \alpha_3 = 1.5[/tex]

A vector is a linear combination of other vectors when it can be obtained via a system of equations from the other vectors.

Considering the matrices, the system of equations to obtain the values of the variables that make vector b a linear combination of vectors A1, A2 and A3 are given as follows:

Adding the second and the third equation, we have that:

3x + 7y = 2.

Since x = y - 3, the value of y is obtained as follows:

3(y - 3) + 7y = 2

3y - 9 + 7y = 2

10y = 11

y = 1.1.

Then the value of x is of:

3x = 2 - 7(1.1)

x = [2 - 7(1.1)]/3

x = -1.9.

The value of z is obtained as follows:

z = 1 - 2x - 3y

z = 1 - 2(-1.9) - 3(1.1)

z = 1.5.

In the desired notation, these values are given as follows:

Step-by-step explanation: The range of the function is the set of all its output values. To find the range of f(a) = 5 + 1/2a when the domain is (0, 4, 6), we can substitute these values into the function and see what the output is:

f(0) = 5 + 1/2 * 0 = 5

f(4) = 5 + 1/2 * 4 = 7

f(6) = 5 + 1/2 * 6 = 8

So the range of f(a) is the set of values {5, 7, 8}.

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given that, A boat is heading towards a lighthouse, whose beacon-light is 111 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 6°, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 13°

The number of peaks, symmetry, tendency to skew, and homogeneity of a distribution are all indicators of its shape.

Explain about the shape of the distribution?

There are two types of data item distributions: symmetric and asymmetric. The "normal distribution" and the "skewed distribution" are two prevalent illustrations of both symmetry and asymmetry. The distribution's two halves are mirror images of one another in a symmetrical distribution.

The number of peaks, the presence of symmetry, the propensity to skew, and the homogeneity of a distribution all help to explain its shape. (Graphs with skewed distributions show a greater number of points on one side than the other.) PEAKS: Graphs frequently show maximums or peaks in a certain area.

The value of the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

A = 9x² - 8x - 20   be equation (1)

On simplifying the equation , we get

A = 9x² - 18x + 10x - 20

On factorizing the equation , we get

A = 9x ( x - 2 ) + 10 ( x - 2 )

Taking the common factors in the equation , we get

A = ( 9x + 10 ) ( x - 2 )

So , when A = 0

( 9x + 10 ) = 0

x = -10/9

The assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

How can the parametric equation be found?

The absence of points and lines renders the question insufficient.

I will therefore utilize the following presumptive parameters:

As the line traverses: (5, -1, 3)

The direction is  ~v = <1, 0, -2>

The parametric equation of the line is represented as:

r<x,y,z> = Line + t<direction>

This gives

r<x,y,z> = (5, -1, 3) + t<1, 0, -2>

Express the equation in terms of x, y and z

x = 5 + t * 1

y = -1 + 0 * t

z = 3 -2 * t

Solve the equations

x = 5 + t

y = -1

z = 3 -2t

The quadratic function with roots x* and x** is given by the equation presented as follows:

y = a(x - x*)(x - x**)

The roots = zeros are the values of x for which the graph of the function crosses the x-axis, hence:

x* = 30, x* = 50.

Then the function is:

y = a(x - 30)(x - 50)

y = a(x² - 80x + 1500).

When x = 0, y = 45, hence the leading coefficient a is obtained as follows:

It is also used in many fields including statistics, finance, engineering, and sciences to make decisions based on uncertain data.

The problem requires the use of the normal approximation to the binomial distribution to estimate the probabilities. Let X be the number of flights that arrive on time out of 186 flights. Then X follows a binomial distribution with parameters n = 186 and p = 0.88.

We can use the normal approximation to estimate the probability of X taking different values. Let's denote the mean and standard deviation of X as mu and sigma respectively:

mu = np = 186 × 0.88 = 163.68

sigma = √(np(1-p)) = √(186 × 0.88 × 0.12) = 5.55

(a) P(159) = P(X = 159) can be estimated using the normal distribution using the Z-score:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(159) ≈ P(Z < -0.77) ≈ 0.2224 (using a standard normal table)

(b) P(X ≥ 159) can be estimated using the cumulative distribution function:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(X ≥ 159) = P(Z ≥ -0.77) = 1 - P(Z < -0.77) = 1 - 0.2224 = 0.7776

(c) P(X < 161) can be estimated using the cumulative distribution function:

Z = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

P(X < 161) = P(Z < -0.36) = 0.3545 (using a standard normal table)

(d) P(161 ≤ X ≤ 174) can be estimated using the cumulative distribution function:

Z1 = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

Z2 = (174 - mu) / sigma = (174 - 163.68) / 5.55 = 1.51

P(161 ≤ X ≤ 174) = P(Z1 < Z < Z2) = P(Z < 1.51) - P(Z < -0.36) = 0.9330 - 0.3545 = 0.5785
