lol sorry I know it but don’t know how up to right it sorry

The standard deviation of a sample proportion is given by the formula:

σ = sqrt((p * (1 - p)) / n)

where σ is the standard deviation, p is the sample proportion, and n is the sample size.

If we want the standard deviation to be one-half of what it was for a sample of size 100, we can write the following equation:

(sqrt((p * (1 - p)) / n)) / 2 = sqrt((p * (1 - p)) / 100)

To simplify the equation, we can square both sides:

((p * (1 - p)) / n^2) / 4 = (p * (1 - p)) / 100

Simplifying further:

100 * n^2 = 4 * 1

n^2 = (4 * 1) / 100

n^2 = 0.04

Taking the square root of both sides:

n = sqrt(0.04)

n = 0.2

Therefore, the sample size should be 0.2. However, since the sample size must be a positive integer, we round it up to the nearest whole number. Therefore, the sample size should be 1.

.Step-by-step explanation:

Answer:

First we need to solve the linear equation for y because we need to get the slope. Once we have the slope we need to convert it to its negative reciprocal, this means to just change the sign of the slope and flip it. The negative reciprocal is always perpendicular to the original slope.

2y = - 6x + 8

y = (-6x/2) + 8/2

y = - 3x + 4

The current slope is -3 or -3/1

The negative reciprocal is 1/3

The range of the function represented by y = 15x + 20, where y is Kim's daily earnings and x is the number of bikes she assembles, is $20 ≤ y ≤ $110.

The range of a function is the set of values of y possible values of the dependent variable after substituting values for the independent variable(domain).

The total amount she earns can be represented by

y = 15x + 20

where y is her daily earnings and x is the number of bikes she assembles

If Kim's boss daily goal is to assemble no more than 6 bicycles a day, then the value of x will only range from 0 to 6(whole number).

domain : {x| 0 ≤ x ≤ 6}

where x is a whole number

Substituting the minimum and maximum value of x in the function.

y = 15(0) + 20     when x = 0

y = 20

y = 15(6) + 20     when x = 6

y = 110

Step-by-step explanation:

See attached. I know (very haphazard). But the basic method is to inverse the trig function. This gives you the position of the terminal angle. -45 degrees means that you turned 45 degrees clockwise and are in quadrant 4. This corresponds to an angle of rotation of 315 degrees counter clockwise which is what we are looking for since the specified domain is betwern 0 and 360 degrees or 0 and 2 pi.

The next thing to remember is that Tan is also negative in Quadrant 2 (using the ASTC rule). This corresponds to an angle of rotation of 180 - 45 = 135 degrees.

final answer:

The planet XYZ traveling about the star ABC in a circular orbit takes 24 hours to make an orbit. Assume that the orbit is a circle with a radius of 83,000,000 mi. The linear speed of XYZ in miles per hour is approximately 1,093,333 miles per hour.

  What is the orbit and what is the linear speed?

           An orbit refers to the path taken by an object, such as a planet, as it circles around another object, such as a star. The speed of the planet is its rate of movement, measured in linear units like miles or kilometers per hour, as it travels around the orbit.

         These are terms that are important to understanding the solution to the problem provided. The linear speed of XYZ in miles per hour is approximate _____ miles per hour. (Round to the nearest integer as needed.)

        The planet XYZ travels around the star ABC in a circular orbit that takes 24 hours to complete. The orbit is a circle with a radius of 83,000,000 miles.

To find the linear speed of XYZ in miles per hour, it is necessary to use the formula for the circumference of a circle.

          Circumference = 2πr Circumference

                                    =2πr Substitute 83,000,000 for r in the formula.

          Circumference = 2π(83,000,000)

           Circumference = 522,000,000 π

     The orbit's circumference is 522,000,000 π miles.

      The distance traveled by XYZ in one hour is the linear speed. The linear speed of XYZ in miles per hour is calculated as follows:

             Speed = Distance/TimeSpeed

                         = Circumference/24Speed

                         = (522,000,000 π)/24

              Speed = 21,750,000 π

    The linear speed of XYZ in miles per hour is 21,750,000 π miles per hour.

To get an approximate answer, π is equal to 3.14.

             Speed ≈ 21,750,000 (3.14)

             Speed ≈ 68,295,000

 The linear speed of XYZ in miles per hour is approximately 68,295,000 miles per hour. Rounded to the nearest integer, the linear speed is approximately 1,093,333 miles per hour.

For annual demand up to 28,750 units, purchasing from the vendor at $10 per unit would be the best option. For annual demand exceeding 28,750 units, producing in-house would be more cost-effective.

To determine the range of annual demand for each alternative, we need to compare the costs of purchasing and producing for different demand levels.

1. Purchasing from the vendor:

The cost of purchasing is $10 per unit, regardless of the annual demand. Hence, the total cost for purchasing is simply the cost per unit multiplied by the annual demand.

2. Producing in-house:

The in-house process has a fixed cost of $230,000 per year, which remains constant regardless of the demand. The variable cost per unit is $8. Therefore, the total cost of producing in-house consists of the fixed cost plus the variable cost per unit multiplied by the annual demand.

By comparing the total costs for each alternative, we can determine the range of demand for which each option is optimal.

Let's denote the annual demand as "D":

- For purchasing from the vendor, the total cost is 10D.

- For producing in-house, the total cost is 230,000 + 8D.

To find the range of demand, we set the two costs equal to each other:

10D = 230,000 + 8D.

Simplifying the equation:

2D = 230,000,

D = 115,000.

Therefore, for annual demand up to 28,750 units (115,000/4), purchasing from the vendor at $10 per unit is the best option. For annual demand exceeding this threshold, producing in-house would be more cost-effective.

Based on the analysis, the manager should choose to purchase the appliance from the vendor when the annual demand is up to 28,750 units. Beyond that demand level, it would be more economical to produce the appliances in-house due to the fixed cost being spread over a larger number of units, resulting in a lower cost per unit.

and then, plot these points on the graph:

(1,2) ... (2,4) ... (3,6) ... (4,8) ...

The graph of the function f(x) = -2sin(x) starts at the midline (y = 0) and reaches its maximum or minimum point closest to the midline at (π/2, -2).

Start by plotting the midline, which is the x-axis (y = 0). This is the starting point for the graph.

Find the maximum or minimum point on the graph closest to the midline. In this case, the maximum or minimum point is a maximum point because the coefficient of sin(x) is negative (-2). The maximum point occurs at π/2 on the x-axis.

Plot the maximum point on the graph at (π/2, -2). This point represents the highest or lowest point on the graph closest to the midline.

From the maximum point, the graph will start to decrease. Since the coefficient of sin(x) is -2, the graph will have a steeper slope compared to the graph of sin(x).

As x increases from π/2, the graph will continue to decrease until it reaches the next minimum point, which will be at 3π/2.

Continue plotting points on the graph by evaluating the function at various x-values and connecting them smoothly to create a sinusoidal curve.

Repeat the pattern of the graph for every interval of 2π, as the sine function is periodic.

Finally, label the x-axis as "x" and the y-axis as "f(x)" or "y" to indicate the function being graphed.

Answer:

The name of the solid with 20 faces that are congruent equilateral triangles is icosahedron.

The solid you are referring to is called an icosahedron. An icosahedron is a specific type of convex polyhedron that has 20 faces. In this case, all 20 faces are congruent equilateral triangles. Option d is correct answer.

To understand why this solid is called an icosahedron, let's break down the term. "Icosa-" comes from the Greek word for twenty, while "-hedron" means face. Therefore, an icosahedron is a polyhedron with twenty faces.

Each face of an icosahedron is an equilateral triangle, meaning that all three sides of the triangle are equal in length, and all three angles are equal to 60 degrees. Since all 20 faces are congruent, they have the same side lengths and angles.

The icosahedron has a total of 12 vertices and 30 edges. The vertices are the points where three edges meet, and the edges are the line segments connecting the vertices. The icosahedron has a symmetrical and regular structure, making it one of the five Platonic solids.

The derivative of the given function  in the form sum or difference is given by, g' (x) = 24 x³ - 7

Given the function is,

g (x) = [6 x⁶ - 7 x³]/x²

g (x) = (6 x⁶)/x² - (7 x³)/x²

g (x) = 6 x⁶⁻² - 7 x³⁻², since the division in exponential means subtraction of powers.

g (x) = 6 x⁴ - 7 x

Differentiating the simplified above function with respect to the variable 'x' we get,

d/dx [g (x)] = d/dx [6 x⁴ - 7 x]

g' (x) = d/dx (6 x⁴) - d/dx (7 x)

g' (x) = 6 d/dx (x⁴) - 7 d/dx (x)

g' (x) = 6 (4 x³) - 7 * 1

g' (x) = 24 x³ - 7

Answer:

To find the absolute change in population from 2007 to 2009, we can subtract the initial population in 2007 from the final population in 2009:

Absolute change = Final population - Initial population

= 6,200 - 3,900

= 2,300 people

Therefore, the absolute change in population from 2007 to 2009 is 2,300 people.

To find the percent increase (relative change) in population, we can use the formula:

Percent increase = (Absolute change / Initial population) x 100%

Substituting the values given in the problem, we get:

Percent increase = (2,300 / 3,900) x 100%

= 58.97%

Therefore, the population increased by approximately 58.97% from 2007 to 2009. Rounded to the nearest tenth of a percent, the percent increase is 59.0%.
