Answer:

The standard deviation of the sampling distribution is [tex]\sigma =0.0087[/tex]

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  1500

     The population proportion is  [tex]p = 0.013[/tex]

Generally the standard deviation of this sampling distribution is mathematically represented as

      [tex]\sigma = \sqrt{ \frac{p (1- p)}{ n} }[/tex]

=>     [tex]\sigma = \sqrt{\frac{0.13(1-0.13)}{1500} }[/tex]

=>   [tex]\sigma =0.0087[/tex]

The standard deviation of the considered sampling distribution of the proportion supporting the increase is 0.0027 approx.

Suppose the sample proportion be denoted by [tex]\hat{p}[/tex], then, its distribution is normally distributed with mean [tex]p[/tex] and the standard deviation of distribution of [tex]\hat{p}[/tex] is given by

 [tex]\sigma = \sqrt{\dfrac{p(1-p)}{n}}[/tex]

where n is the sample size. It is true until [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

For the given case, we're given that:

Thus, standard deviation of the sampling distribution is approximately 0.0027

Answer: Rewrite equations:

3x=y;x−2y=10

Step: Solve3x=yfor y:

3x=y

3x+−y=y+−y(Add -y to both sides)

3x−y=0

3x−y+−3x=0+−3x(Add -3x to both sides)

−y=−3x

−y

=

−3x

(Divide both sides by -1)

y=3x

x−2y=10

x−23x=10

−5x=10(Simplify both sides of the equation)

Step-by-step explanation:

Answer:

(4, 18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

     = 20 - 1

     = 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

      = 15 - 1

      = 14 (Yep, same as option)

3. y = 5(0) - 1

      = 0-1

      = -1 (Yep, same as option)

4. y = 5(2) - 1

      = 10 - 1

      = 9 (Yep, same as option)

The point (4, 18) is not lies on the given line.

First option is correct.

The equation of line in slope intercept form is,

                              [tex]y=mx+c[/tex]

Where m is slope and c is y intercept.

Given that, m = 5 and c = -1

Substitute above values

Equation of line is,

                         [tex]y=5x-1[/tex]

Substitute first option (4, 18) in equation of line.

                     [tex]18=5(4)-1\\\\18=20-1\\\\18=19[/tex], which is invalid equation.

Hence, point (4, 18) is not lies on the given line.

Given that,

Radius, r = 10

Angle, [tex]\theta=60^{\circ}[/tex]

We need to find the area of the sector. The formula for the area of the sector is given by :

[tex]A=\dfrac{\theta}{360}\pi r^2\\\\=\dfrac{60}{360}\times \dfrac{22}{7}\times (10)^2\\\\=52.3\ \text{unit}^2[/tex]

Both are solutions of x.

Step-by-step explanation:

[tex]x^{2} =49[/tex]

For [tex]x^{2} =f(a)[/tex] the solutions  are [tex]x=\sqrt{f(a)} ,-\sqrt{f(a)}[/tex]

[tex]x=\sqrt{49} ,x=-\sqrt{49}[/tex]

Apply radical rule: [tex]\sqrt[n]{x^n} =a[/tex]

[tex]\sqrt{7^2} =7[/tex]

=7

[tex]-\sqrt{49}[/tex]

Factor the number: [tex]49=-7^2[/tex]

Apply radical rule: [tex]\sqrt[n]{x^n} =a[/tex]

Answer:

5

Step-by-step explanation:

this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5

The value of x makes the equation 3x - 6 = 9 true is: x = 5.

Here, we have,

given that,

the equation is: 3x - 6 = 9

so have,

3x-6=9

We need to combine like terms

=> 3x = 9 + 6

(we add the 6 to add like terms).

becomes, => 3x=15

we then divide the 3 from on both sides

=> 3x/3 = 15/3

we get

=> x=5

Answer:

Monthly charges = $70

Intuition charges = $2710

Step-by-step explanation:

There is intuition fee and per month fee for joining the Pine River country club.

Total cost for 7 months is $3200

Total cost for one and a half years is $3970

one and a half years means 18 months.

To find:

Intuition fee and monthly dues?

Solution:

Let the intuition fee = [tex]i[/tex]

Let the monthly dues = [tex]m[/tex]

Total cost for 7 months can be represented as

[tex]i+7m = 3200[/tex] ..... (1)

Total cost for 18 months can be represented as

[tex]i+18m = 3970 .... (2)[/tex]

Here, we have 2 equations and 2 variables whose values are to be found.

Let us use elimination method to solve the equations.

Subtracting equation (1) from (2):

[tex]11m = 770\\\Rightarrow m = 70[/tex]

Therefore, the monthly dues are $70.

Using equation (1), we can find the value of [tex]i[/tex].

[tex]i + 70\times 7 = 3200\\\Rightarrow i = 3200 - 490\\\Rightarrow i = \$2710[/tex]

Therefore, intuition charges are $2710.
