Two students are selected at random from the class this can be done in 45 ways.

It is necessary for there to be one girl and one boy this is done in 24 ways.

In a given class there are six( 6 ) girls and four( 4 ) boys.

In this case, there are given two cases that two students are selected at random from the class, In how many ways can this be done

And the other case is it necessary for there to be one girl and one boy, how many ways are possible

To solve the two cases we use Combinations;

Total number of students in a class = 6 + 4 = 10

For case ( 1 ):

Two students are selected at random from the class this can be done by;

A = ¹⁰C₂

A = [tex]\frac{10!}{2!*(10-2)!}[/tex]

A = 45

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

The relationship between the cups of flour and the number of healthy muffins baked is C = 11M.

An equation is a representation variable and constants on both sides of the equality showing that terms of both sides of the equality sign are equal.

According to the given Fatima uses 3 cups of flour to bake 33 healthy muffins.

Assuming no. of cups to be C and no. of Muffins to be M.

If we divide M/C we get a scale factor of 11.

Using the probability concept, the proportion of times do we expect the practitioner to guess the correct hand is of 0.44.

The probability of an event in an experiment is calculated as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.

The probability can be interpreted as the proportion of times that we expect a trial to happen.

In the context of this problem, this probability is of 44%, as stated for Emily's model, that is, out of 100 trials, the correct answer was obtained in 44 of them, hence the proportion of times do we expect the practitioner to guess the correct hand is of 0.44.

The most appropriate choice for percentage will be given by-

a)Percentage of people arrive at their office before 7 am = 10%

b)Percentage of people arrive at their office after 7:59 am = 64 %

What is percentage?

Suppose, there is ratio of two numbers and it has to be expressed as a fraction of 100, percentage is that ratio.

So percentage is the ratio of two numbers expressed as a fraction of 100.

Here,

a) Number of people arrive at their office before 7 am = 15

Total number of people = 15 + 39 + 75 + 21

                                        = 150

Percentage of people arrive at their office before 7 am = [tex]\frac{15}{150}\times 100[/tex]

                                                                                            = 10%

b)Number of people arrive at their office after 7:59 am = 75 + 21

                                                                                           = 96

Percentage of people arrive at their office after 7:59 am = [tex]\frac{96}{150}\times 100[/tex]

                                                                                              = 64 %

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.

Answer:

v = -7

Step-by-step explanation:

-38 = -3 + 5v

add 3 to both sides:

-38 + 3 = -3 + 5v + 3

-35 = 5v

divide both sides by 5:

-35/5 = 5v/5

v = -7

The equation is x = -4.

Use slope and slope intercept form  y = mx + b,

Slope = y2 - y1/x2 - x1

Slope = 5 - (-2 )/-4 - (-4) = 7/0 = undefined

Equation of point-slope form,

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

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.
