The correct answer is (D) If A is the given matrix, then the augmented matrix represents the equation Ax =0. The reduced echelon form of this matrix indicates that Ax =0 has only the trivial solution. Therefore, the columns of A form a linearly independent set.

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics. In computer graphics, where they have been used to describe picture rotations and other transformations, matrices have vital applications as well.

Mathematically, assume that B = {v₁, v₂, v₃, ........} is the set of vectors. Then B will be linearly independent if the vector equation

y₁v₁ + y₂v₂ + y₃v₃ + ........ = 0 possesses the trivial solution such that

y₁ = y₂ = y₃ = ........ = 0.

Let A be a matrix, then columns of A will be linearly independent if the equation Ax = 0 possesses the trivial solution. In other words, The row space of matrix A is the span of its rows. The column space denoted by

C(A) is the span of A’s columns. The dimension of the row and column spaces is always the same, which is known as the rank of A.

Step-by-step explanation:

To discover the coordinates of a polar point, you need to recognize its distance from the origin (the polar axis) and the perspective it makes with the superb x-axis.

The space is commonly denoted via the image r, and the angle is denoted by means of the image θ. To devise a polar point, you start by locating the foundation and drawing a line alongside the polar axis.

Subsequently, you measure the angle θ from the fine x-axis, shifting counterclockwise.

In the end, your degree the distance r from the starting place and plot the factor on the corresponding location.

To find the coordinates of a polar point, you can use the subsequent formulas:

x = r cos(θ)

y = r sin(θ)

Right here, x and y constitute the rectangular coordinates of the factor, while r and θ constitute the polar coordinates.

Those formulas let you convert between polar and rectangular coordinates, which can be useful for graphing and solving problems in diverse branches of mathematics and physics.

If a 6-ounce bottle of medicine contains 36 doses, we can use a proportion to find how many doses are in a 15-ounce bottle:

6 ounces / 36 doses = 15 ounces / x doses

Cross-multiplying, we get:

6 x = 36 * 15

6 x = 540

Dividing both sides by 6, we get:

x = 90

Therefore, a 15-ounce bottle of the same medicine contains 90 doses.

The length of the arc that outlines the sector is 15π centimeters.

What is the area of sector?

The area of a sector is given by the formula:

[tex]A=\frac{\theta}{360^{\circ}} \times \pi r^2[/tex]

where A is the area of the sector, θ is the central angle of the sector (in degrees), and r is the radius of the circle.

To find the area of the shaded sector, we need to use the formula -

[tex]Area=\frac{central \angle}{360^{\circ}} \times \pi r^2[/tex]

In this case, the central angle is 270° and the radius is 10 cm. Plugging these values into the formula, we get:

Area of sector = [tex]\frac{270^{\circ}}{360^{\circ}} \times \pi (10)^2[/tex]

Area of sector = (3/4) x π x 100

Area of sector = 75π

So the area of the shaded sector is 75π centimeters.

To find the length of the arc that outlines the sector, we need to use the formula:

Length of arc = (central angle / 360°) x 2πr

Plugging in the values of the central angle and radius, we get:

Length of arc = (270/360°) x 2π x 10

Length of arc = (3/4) x 20π

Length of arc = 15π

Hence, the length of the arc that outlines the sector is 15π centimeters.

A) Sum of (Score) ΣX equal to 63 and (Mean)M equal to 7.

B) Sum of Score ΣX equal to 96.

C) On the other side of the seesaw, the sixth score must be one point below the mean.

D)The sample has 7 scores.

E) To get the mean for the combined sample, the scores for each sample added together are 6.

A) Here we have to calculate the sum of scores (ΣX),

Add all of the scores together:

8 + 2 + 5 + 7 + 12 + 9 + 11 + 3 + 6

= 63

We sum up all of the scores and divide by the total number of scores (in this example, 9), which gives us the mean (M):

M = ΣX / n

M = 63 / 9

M = 7

B)The following formula may be used to get the value of X when the sample size (n) is 12 and the mean (M) is 8.

ΣX = M x n

ΣX = 8 x 12 = 96

Therefore, ΣX = 96.

C) The sixth score would need to be one point below the mean to balance the total if we know that the first five scores are all one point above the mean. This is thus because, like a seesaw, the mean represents the point of equilibrium in a group of scores. The seesaw is skewed up on one side if five scores are above the mean; the only way to balance it out is to position the sixth score on the other side, one point below the mean.

D) The following formula may be used to get the total number of scores in a sample with a mean (M) of 8 and a sum (X) of 56 scores:

ΣX = M x n

56 = 8 x n

n = 7

Hence, The sample has 7 scores.

E) The sum of the scores for each sample must first be determined in order to get the mean for the combined sample:

First sample, n = 10, M = 8, and the following:

ΣX1 = M x n

ΣX1 = 8 x 10

ΣX1 = 80

Second sample with n = 5 and M = 2:

ΣX2 = M x n

ΣX2 = 2 x 5

ΣX2 = 10

We just put the two amounts together to obtain the combined sample's overall sum of scores (ΣX):

ΣX = ΣX1 + ΣX2

ΣX = 80 + 10

ΣX = 90

We divide the entire sum of scores by the total number of scores to determine the mean for the combined sample:

M = ΣX / n

M = 90 / (10 + 5)

M  = 6

Hence, six is the sample's overall mean.

The coefficient of variation (CV) calculator is a tool that helps you calculate the relative variability of a dataset. The coefficient of variation is the ratio of the standard deviation (SD) to the mean (μ) expressed as a percentage, and it is used to compare the variability of datasets with different units or scales.

The formula for the coefficient of variation is:

CV = (SD / μ) x 100%

To use a coefficient of variation calculator, you need to input the values of the dataset, either one by one or as a list, and select the type of data you have (sample or population). The calculator will then calculate the mean, standard deviation, and coefficient of variation of the dataset.

The coefficient of variation is commonly used in quality control, finance, and other fields to compare the variability of different datasets. A high coefficient of variation indicates that the dataset has a large amount of variability relative to the mean, while a low coefficient of variation indicates that the dataset has a small amount of variability relative to the mean.

The coefficient of variation is only meaningful when the mean is non-zero. If the mean is zero or close to zero, the coefficient of variation can be infinite or undefined.
