Step-by-step explanation:

By adding a duplicate of the identity matrix to the augmented matrix, which was formed, it is possible to find the inverse of a square matrix using row reduction.

If the matrix is capable of being reduced to the identity, the identity matrix will simultaneously change into the inverse matrix. A rectangular array of numbers, arranged in rows and columns, is referred to as a matrix. The dimension, or order, of a matrix, indicates how many rows and columns there are in the array. For example, if a matrix has m rows and n columns, its order is expressed as mxn.

Answer:

[tex]d=11.3125[/tex]

Step-by-step explanation:

Given

[tex]\frac{-4(-8.625+2d)}{-8} +3=10[/tex]

Lets solve for [tex]d.[/tex]

Start on the left side with the fraction.

Factor -4 out of -8.

[tex]\frac{-4(-8.625+2d)}{-4(2)} +3=10[/tex]

Cancel the common factor of -4.

[tex]\frac{-8.625+2d}{2} +3=10[/tex]

Subtract 3 from both sides.

[tex]\frac{-8.625+2d}{2} =7[/tex]

Multiply both sides by 2.

[tex]\frac{-8.625+2d}{2} *2=14[/tex]

Cancel the common factor of 2.

[tex]-8.625+2d=14[/tex]

[tex]2d-8.625=14[/tex]

Add 8.625 to both sides.

[tex]2d=22.625[/tex]

Divide both sides by 2.

[tex]d=11.3125[/tex]

The measure of angle E if The measure of angles is 2x + 13, 11x - 6 and 89°, is 37°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

Given:

The measure of angles is 2x + 13, 11x - 6 and 89°,

Use the exterior angle theorem and find the value of x as shown below,

2x + 13 + 89 =  11x - 6

2x + 102 = 11x - 6

9x = 108

x = 12

Thus, the measure of ∠ E = 2 × 12 + 13

∠ E = 24 + 13

∠ E = 37°

On solving the provided question, we can say that 12,12,12,22,23,32,43 Mean Absolute Deviation (MAD): 8.8979591836735

The average of the absolute deviations from the center point within a dataset is called the mean absolute deviation. This statistic summarizes the statistical spread or variability. Each data point's average distance from the mean is known as the dataset's mean absolute deviation. This gives a sense of the dataset's variability. To determine the absolute value, take the mean from each integer in the dataset and then subtraction. Take the total of the absolute values next. Subtract the aforementioned sum from the total number of items in the dataset to obtain the mean absolute deviation.

Answer:

To form a right triangle, one of the sides of the triangle must be the hypotenuse and the other two sides must be the legs. The hypotenuse is the longest side of a right triangle and the side opposite the right angle. In this case, the side with length 5x is the hypotenuse. Therefore, the sides with lengths 3x and 24 must be the legs.

We can use the Pythagorean Theorem to determine the value of x that will make this a right triangle. The Pythagorean Theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, we have:

5x^2 = 3x^2 + 24^2

Solving for x, we get:

x = sqrt(24^2/(5^2 - 3^2)) = sqrt(576/16) = 6

Therefore, a value of x = 6 will make this a right triangle.

Answer:

41 1/4 and 15

Step-by-step explanation:

So for the first question, we know that a single inch of thread has 16 1/2 bolts. We know that there are 2 1/2 inches of thread.

To find the total anount of bolts in the thread, we can multiply 2 1/2 by 16 1/2:

2 1/1*16 1/2 = 41 1/4

That is our first answer.

For our next answer, we know that a book is 1 7/8 inches big.

The bookshelf is 28 1/8 inches big.

To find how many of the 1 7/8 inch big books can fit in the 28 1/8 inch big bookshelf, we can divide 28 1/8 by 1 7/8:

28 1/8/1 7/8

Hi there!

[tex]\large\boxed{t = 12.60 \text{ days}}[/tex]

We can solve this by setting the equation equal to 150:

[tex]150 = \frac{230}{1 + 56.5e^-0.37t}[/tex]

Cross-multiply and divide:

[tex]150 (1 + 56.5e^{-0.37t})= 230[/tex]

Divide both sides by 150:

[tex]1 + 56.5e^{-0.37t} = 1.5333[/tex]

Isolate for t by subtracting both sides by 1 and dividing by 56.5:

[tex]56.5e^{-0.37t} = 0.5333[/tex]

[tex]e^{-0.37t} = 0.0094395[/tex]

Take the natural log to solve for t:

[tex]ln (0.0094395) = -0.37t[/tex]

[tex]-4.6628522 = -0.37t[/tex]

Divide both sides by -0.37:

t = 12.60 days.

From the given graph, at Point B a total of 8000 fluffernutters & 500 blank books could be produced.

The study of graphs, which are mathematical constructions used to represent pairwise relationships between things, is known as graph theory in mathematics. In this context, a graph is made up of vertices connected by edges.

In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other forms of graphs.

Straight line graphs called linear graphs are used to show the relationship between two quantities. This graph makes it easier to show a result as a collection of straight lines. The term "linear" simply means a straight line; curves, dots, bars, etc. are not used.

9% interest rate

Step-by-step explanation:

Investment = principal = $4000

Interest amount = $1080

Period, t = 3 years

Simple interest = principal * rate * time

1080 = 4000 * rate * 3

1080 = 12000 * rate

Rate = 1080 / 12000

Rate = 0.09

The rate as a percentage = 0.09 * 100% = 9%
