Since the multiplication of the matrices (A x B) x C and A x (B x C) are equal, the multiplication of matrices is associative.

Matrices are multiplied multiplying the lines of the first matrix by the columns of the second matrix.

The multiplication of the matrices being associative means that:

(A x B) x C = A x (B x C).

Hence, applying the rules, of the multiplication of the lines by the columns, we have to solve for the two cases, and find the results.

Then:

[tex](AB)C = \left[\begin{array}{ccc}11&-8&37\\21&28&15\end{array}\right] \times \left[\begin{array}{c}1\\-2\\0\end{array}\right][/tex]

As the multiplication of a 2 x 2 matrix by a 2 x 3 matrix results in a 2 x 3 matrix, and then we multiply by C as follows:

[tex]\left[\begin{array}{ccc}11&-8&37\\21&28&15\end{array}\right] \times \left[\begin{array}{c}1\\-2\\0\end{array}\right] = \left[\begin{array}{c}27\\-35\\\end{array}\right][/tex]

Multiplying the lines by the columns, we have that the first line is, for example:

11 x 1 - 8 x (-2) + 37 x 0 = 27.

In the second case, the multiplication of B and C is given by:

[tex]BC = \left[\begin{array}{c}5\\-8\end{array}\right][/tex]

Multiplying by A, we get the same result as above, hence the multiplication of matrices is associative.

The pair of vertically opposite angles are ∠1 and ∠3 and ∠4 and ∠2.

Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines and are opposite to each other.

Vertically opposite angles share the same vertex  point.

In other words, vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines

Vertically opposite angles are congruent to each other.

For a sale of $8400 made his gross pay is $373.21

In this question, we have been given Mike Lasueze is guaranteed a minimum salary of $220 per week or 5.5 percent of his total sales, whichever is greater.

We need to find his gross pay for a week in which his total sales were $8,400

weekly pay = $220

commission = 5.5% of sales

                    = 0.055 of sales

Let m be the total sale and his gross pay be represented by y.

So, we get an equation for the total/gross pay:

y = 0.055x + 220

Required is the gross pay y for x = 8400

y = 0.055(8400) + 220

y = 682

Therefore, for a sale of $8400 made his gross pay is $373.21

The fact that voting might not be compulsory will make the voter ranks the candidate as their proximity, and the median voter wins the vote

The fact that resources are needed to finance reelection campaigns will make the probability of the median voter be in danger

According to median voter model theorem, at-least there must be two candidates

Being that we have two candidates for elected office, let's see how the following may affect the conclusions of the median voter model:

Part a

Voting might not be compulsory:

Here, voter ranks the candidates as per as their proximity, and the median voter will win the vote.

Part b

We need to find the volume of a rectangular prism with dimensions 6 ft, 10 ft, and 12 ft:

• The volume of a rectangular prism is given by the product of its dimensions.

Thus, the volume V of the room is given by:

Therefore, that volume is 720 cubic feet.

The rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters is -0.8571 cm/s

dr/dt = -0.8571 cm/s

A cylinder's volume can be calculated using...

V = πr²h

For a constant volume, by differentiating with respect to t, we obtain...

0 = π(2rh·dr/dt + r²·dh/dt)

Finding for dr/dt, we have ...

dr/dt = dh/dt(-r²/(2rh)) = (dh/dt)(-r/(2h))

Filling in the given numbers gives ...

dr/dt = (0.5 cm/s)(-7 cm)/(2·6 cm)

dr/dt = -0.8571 cm/s

Therefore, the rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters is -0.8571 cm/s

(5/4) < 1.3 < 1 (8/25)

Explanation

We are told to order the given numbers from the least to the greatest number.

To do that, we will need to express the numbers in decimal form, so it is evident which one is bigger.

1 (8/25)

= 1 + (0.32)

= 1.32

1.3

= 1.30

(5/4)

= 1.25

We can easily see that

1.25 < 1.30 < 1.32

In the form of the numbers given, we have

(5/4) < 1.3 < 1 (8/25)

The alternate hypothesis for the directional z-test is:

Local resident's average > National average

A hypothesis is a theory put up to explain a phenomenon. A hypothesis must be testable according to the scientific method for it to be considered a scientific hypothesis. Scientific hypotheses are typically based on prior observations that cannot be adequately explained by the current body of knowledge.

One of the ideas put out in the hypothesis test is the alternate hypothesis.

A researcher wants to know if people in his neighborhood have a better well-being than people nationwide.
