A group contains n men and n women. 2n! number of ways are there to arrange these people in a row if the men and women alternate. Arrangement is known as permutation.

A permutation of a set in mathematics is, broadly speaking, the rearrangement of its elements if the set already has an ordered structure into a sequence or linear order. The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."

When the order of the arrangements counts, a permutation is a mathematical technique that establishes the total number of alternative arrangements in a collection. Choosing only a few items from a collection of options in a specific sequence is a common task in arithmetic problems.

The cost to rent each chair and table, based on the total cost to the party rental company, is:

Let x be the cost of renting one chair and y be the cost of renting one table.

From the first piece of information given, we can write the equation:

3x + 2y = 25

From the second piece of information given, we can write the equation:

5x + 6y = 65

Solving these equations using elimination gives:

3x + 2y = 25

5x + 6y = 65

15x + 10y = 125

15x + 18y = 195

Subtracting gives:

0x + 8y = 70

y = $ 8.75

The cost to rent a chair is:

3x + 2 (8.75) = 25

Amita can only use one of the possible molds if she wants a rectangular prism with a square base and volume of 28 cubic centimeters.

Let the length, width, and height of the rectangular prism be x, y, and z respectively. Since the volume of the prism is 28 cubic centimeters, we have:

x * y * z = 28

Since x, y, and z are whole numbers, we can find all possible combinations of three factors whose product is 28. These are:

1 * 1 * 28

1 * 2 * 14

1 * 4 * 7

2 * 2 * 7

Therefore, there are four different molds that Amita can make.

If Amita wants the mold to have a square base, then the length and width of the base must be equal. We can see that only one of the above combinations has equal length and width, which is:

Answer:

Option (B)

Step-by-step explanation:

There are two lines on the graph representing the system of equations.

First line passes through two points (-3, 1) and (-2, 3).

Slope of the line = \(\frac{y_2-y_1}{x_2-x_1}\)

                           = \(\frac{3-1}{-2+3}\)

                       m = 2

Equation of the line passing through (x', y') and slope = m is,

y - y' = m(x - x')

Equation of the line passing through (-3, 1) and slope = 2 will be,

y - 1 = 2(x + 3)

y = 2x + 7 ----------(1)

Second line passes through (0, 1) and (-1, 4) and y-intercept 'b' of the line is 1.

Let the equation of this line is,

y = mx + b

Slope 'm' = \(\frac{y_2-y_1}{x_2-x_1}\)

               = \(\frac{4-1}{-1-0}\)

               = -3

Here 'b' = 1

Therefore, equation of the line will be,

y = -3x + 1 ---------(2)

From equation (1) and (2),

2x + 7 = -3x + 1

5x = -6

x = \(-\frac{6}{5}\)

x = \(-1\frac{1}{5}\)

From equation (1),

y = 2x + 7

y = \(-\frac{12}{5}+7\)

  = \(\frac{-12+35}{5}\)

  = \(\frac{23}{5}\)

  = \(4\frac{3}{5}\)

Therefore, exact solution of the system of equations is \((-1\frac{1}{5},4\frac{3}{5})\).

Option (B) will be the answer.

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

(-0.1740 , 0.1672)

Step-by-step explanation:

Step(i):-

Given A survey found that 31 of 60 randomly selected women

First sample proportion

                \(p_{1} = \frac{x_{1} }{n_{1} } = \frac{31}{60} = 0.5166\)

Second sample proportion

               \(p_{2} = \frac{x_{2} }{n_{2} } = \frac{38}{73} = 0.520\)

Level of significance = 0.05

Z₀.₀₅ = 1.96

Step(ii):-

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

\(((p_{1} ^{-}-p^{-} _{2} - Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ), (p_{1} ^{-}-p^{-} _{2} +Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ))\)

where

\(Se(p_{1} - p_{2} ) = \sqrt{\frac{p_{1} (1-p_{1} )}{n_{1} }+\frac{p_{2}(1-p_{2} }{n_{2} } }\)

\(Se(p_{1} - p_{2} ) = \sqrt{\frac{0.5166 (1-0.5166 )}{60 }+\frac{0.520(1-0.520 }{73 } } = 0.08706\)

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

\(((p_{1} ^{-}-p^{-} _{2} - Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ), (p_{1} ^{-}-p^{-} _{2} +Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ))\)

((0.5166-0.520-1.96(0.08706) , 0.5166-0.520+1.96(0.08706))

(-0.1740 , 0.1672)

The probability they choose all democrats is 0.01805

From the question, we have the following parameters that can be used in our computation:

Republicans = 11

Democrats = 8

Number of selections = 4

If the selected people are all democrats, then we have

P = P(Democrats) * P(Democrats | Democrats) in 4 places

using the above as a guide, we have the following:

P = 8/19 * 7/18 * 6/17 * 5/16

Evaluate

P = 0.01805

Mean and standard deviation is more affected by extreme observations.

Mean is the summation of all the values divided by the total number of values. It is also called as average. Median is the middle value.Standard deviation is the dispersion of a dataset relative to its mean. In case of extreme items arithmetic mean is affected very much. For this reason, it no longer remains representative of the distribution. As standard deviation is the positive square root of the arithmetic mean of the square of deviations of all given values, it is also affected by extreme items. As median is a partition value, it is not affected by extreme items.
