The required sample size to estimate the true proportion of Illinois homes that have air conditioning to within 3% with 99% confidence is of:

1816.

The required sample size is obtained using the z-distribution, as we are working with a confidence interval of proportions.

The equation that determines the margin of error of a confidence interval is presented as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The estimate in this problem, along with the desired margin of error, are given as follows:

[tex]\pi = 0.56, M = 0.03[/tex]

Then the needed sample size is calculated as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 2.575\sqrt{\frac{0.56(0.44)}{n}}[/tex]

[tex]0.03\sqrt{n} = 2.575\sqrt{0.56 \times 0.44}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.56 \times 0.44}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.56 \times 0.44}}{0.03}\right)^2[/tex]

n = 1816. (rounded up, as a sample size of 1815 would have a margin of error slightly above 3%).

x² - x - 4 = 0 is the equation that can be used to find the value of x.

Given,

The dimensions of a sand box is given as (x + 2) inches and (x + 1) inches.

The value of the area, in square inches, of the sandbox is equal to the value the perimeter in inches.

We have to find an equation that can be used to find the value of x;

Here,

Consider the sand box as a rectangle.

Area of rectangle = length x width

That is,

Area of sand box = (x + 2) (x + 1) = x² + x + 2x + 2 = x² + 3x + 2

Now, Perimeter of rectangle = 2(length + width)

That is,

Perimeter of sand box = 2(x + 2 + x + 1) = 2(2x + 3) = 4x + 6

Now,

Equate both the equations;

x² + 3x + 2 =  4x + 6

x² + 3x + 2 - 4x - 6 = 0

x² - x - 4 = 0

Therefore,

The equation that can be used to find the value of x is x² - x - 4 = 0

The image point of (3,6) after the transformation T0,-3 o R90° can be found by first applying the transformation T0,-3, which shifts the point 3 units to the right and 3 units down. This results in the point (6,-3). Then, the transformation R90° rotates the point 90 degrees counterclockwise around the origin. This results in the point (-3,6). Therefore, the image point of (3,6) after the transformation T0,-3 o R90° is (-3,6).

Answer:

x = 35

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(x + 110)° is an exterior angle of the triangle , then

x + 35 + x + 40 = x + 110

2x + 75 = x + 110 ( subtract x from both sides )

x + 75 = 110 ( subtract 75 from both sides )

x = 35

The answer contains a brief description of the slope and slope triangle.

What is the slope of line?

Determine the slope of the line using the slope formula given two line-side coordinates. The formula m=(y2-y1)/ describes the slope as the proportion of the change in y values to the change in x values (x2-x1). The coordinates of the first point corresponding to x1 and y1. The second points are situated at the coordinates x2, y2, and. It doesn't matter which point you choose to rank as the first and which as the second.

slope triangle:

A slope triangle is a tool that you can use to visually determine a line's slope. Slope here refers to the degree of steepness.

Imagine that you are a pilot and that you have ascended by 1,000 feet in the air vertically. You have advanced (horizontally) 3,000 feet by the time you are 1,000 feet above the ground. You can calculate how steep your rise was using those two measurements. The inclination increases as the plane move ahead a certain distance.

The rule that describes the composition of transformations of triangle ABC to triangle A''B''C'' is given as follows:

R(x-axis) and T(-6,-2)(x,y) -> second option.

The vertices of the original triangle are given as follows:

A(5,-5), B(1, -2) and C(1,-5).

The triangle A'B'C' was reflected, as the orientation was changed, and the vertices are given as follows:

A'(5,5), B'(1, 2) and C'(1,5).

Hence the rule of the reflection is given as follows:

(x,y) -> (x,-y).

Meaning that it underwent a reflection over the x-axis.

Then triangle A''B''C'' is obtained with a translation of triangle A'B'C', as only the position changed, keeping the orientation equal.

The vertices are given as follows:

A''(-1,3), B'(-5, 0) and C'(-5,3).

Hence the rule is given as follows:

(x,y) -> (x - 6, y - 2).

Which is a translation of 6 units left and 2 units down, meaning that the second option is correct.

Answer:

Step-by-step explanation:

You have transversal n crossing parallel lines l and m, creating angles labeled 1–8. Angles 1, 3, 6, 8 are shown as obtuse, and the others are shown as acute. You want values of x and angles, given certain angle expressions.

The acute and obtuse angles are supplementary. Angles 3 and 5 are "consecutive interior angles", so are supplementary.

  ∠3 +∠5 = 180

  (4x -18) +(3x +52) = 180

  7x +34 = 180 . . . . . . . . . . collect terms

  7x = 146 . . . . . . . . . subtract 34

  x = 20 6/7  . . . . divide by 7

The measures of the angles are ...

  ∠3 = 4x -18 = 4(20 6/7) -18 = 83 3/7 -18 = 65 3/7

  ∠5 = 3x +52 = 3(20 6/7) +52 = 62 4/7 +52 = 114 4/7

Note that the total of angles 3 and 5 is 180°.

The problem asks for the measure of angle 8. Angle 8 is an alternate interior angle with respect to angle 3, so is congruent.

  ∠8 = ∠3 = 65 3/7

Answer:

y = (2/64)x^3

Step-by-step explanation:

y = (2/64)x^3

Substitute in the given values:

When x = 4, y = (2/64)(4^3)

y = 2

Therefore, the equation is correct. To find other combinations of x and y, simply substitute different values for x in the equation and solve for y.

For example, when x = 3,

y = (2/64)(3^3)

y = (2/64)(27)

y = 1.5

The line is the best fit because the sum of the residuals is a small number(1.2), so option D is correct.

A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.

Calculate the residual as shown below,

[tex]Residual = y - \hat{y}[/tex]

12 - 9.1 = 2.9

9 - 11.9 = -2.9

16 - 13.3 = 2.7

14 - 14 = 0

5 - 15.4 = -10.4

24 - 17.5 = 6.5.

Hence, the sum of the residuals is given as follows:

2.9 - 2.9 + 2.7 + 0 - 10.4 + 6.5 = 1.2

The sum of the residual is a small number, so it is the best fit.

Solving the system of equations 5x + 9y = 104x - 3y = 8 and  using elimination, x is 2 and y is 0.

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients. The addition property of equality is used in the elimination technique to solve systems of linear equations. The same value can be added to both sides of an equation. You can therefore add x + y to the left side of the first equation and add 8 to the right side of the equation if your system is x - 6 = 6 and x + y = 8.

Given,

Equation A: 5x + 9y = 10

Equation B: 4x - 3y = 8

Solving the system of equations using elimination,

Multiplying equation B by 3

5x + 9y = 10

12x - 9y = 24

---------------------

17x = 34

x = 2

Equating x = 2 in equation 2

4x - 8 = 3y

Get the Weighted Average Cost of Capital first (WACC). WACC is the minimal return a project must provide in order to be approved. Thus, it is employed to discount a project's projected cash flows to its present value.

WACC = Ke × E/V + Kd × D/V.

where,

Ke is  cost of equity
