To estimate the percentage of a state's voters who support the current

governor for reelection, three newspapers each survey a simple random

sample of voters. Each paper calculates the percentage of voters in their

sample who support the governor and uses that as an estimate for the

population parameter. Here are the results:

• The Herald: n = 1000 voters sampled; sample estimate = 61%

• The Tribune: n = 800 voters sampled; sample estimate = 57%

The Times: n= 600 voters sampled; sample estimate = 71%

All else being equal, which newspaper's estimate is likely closest to the actual

percentage of voters who support the governor for reelection?

Answer:

10 1/2 or 10.5

Step-by-step explanation:

V=l*w*h

Volume = length * width * height

length = 3 1/2 = 3.5

width = 1 1/5 = 1.5

height = 2

input the values V = 3.5 * 1.5 *2

multiply the first two numbers 3.5 * 1.5 = 5.25

multiply the first result by the third number 5.25 * 2 = 10.5

Volume = 3.5 * 1.5 *2= 5.25 * 2 = 10.5 = 10 1/2

3 1/2 * 1 1/5 * 2 = length * width * height = Volume = 10 1/2

Volume = 10 1/2

did test on edge, got 100%

The height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).

The formula for the volume of a rectangular prism is V = Ah, where A is the area of the base and h is the height. Since we are given the volume and the area of the base, we can solve for the height. We have V = ([tex]x^{2}[/tex]-2) * h and V = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3), so we can set these two equations equal to each other and solve for h.

([tex]x^{2}[/tex]-2) * h = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3)

Expanding both sides, we get:

[tex]x^{2}[/tex]h - 2h = [tex]x^{3}[/tex]h - 3[tex]x^{2}[/tex]h + 5xh - 3h

Combining like terms, we get:

([tex]x^{3}[/tex] - 3[tex]x^{2}[/tex] + 5x - 3 - [tex]x^{2}[/tex] + 2 - 5x + 3) * h = 0

Simplifying, we get:

([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) * h = 0

Since [tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2 cannot equal 0 (since it's a cubic polynomial), we can divide both sides by ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) to solve for h:

h = 0 / ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2)

So the height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).

Answer: [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]

Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here, we have 5.4 and notice that there

is only one digit to the left of the decimal point.

Next, we count the number of places the decimal point would

need to move to get back to the original number, 54.

Since we would need to move the decimal point 1 place to the right,

we have an exponent of positive 1.

Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.

So we have [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]

Notice that the exponent is positive.

This is because we would need to move the decimal point to the right in order to get back to the original number.

So 54 can be written in

scientific notation as [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex].

The next three terms in the pattern following the rule 'add 9' are 36, 45, and 54.

Since the pattern follows the rule of adding 9 to get to the next term, we can simply continue this pattern from the last given term, which is twenty-seven triangles. Therefore:

Term four would have twenty-seven plus nine triangles, giving us 36 triangles.

Term five would be thirty-six plus nine, which results in 45 triangles.

Term six is forty-five plus nine, totaling 54 triangles.

The next three terms in the pattern following the rule 'add 9' are 36, 45, and 54.

Answer: 8

Step-by-step explanation:

As per the given volume and radius of the cylinder, the height of the cylinder in the diagram is approximately 8 cm.

In order to determine the height of the cylinder in the given diagram, we first need to understand the formula for calculating the volume of a cylinder. The formula for the volume of a cylinder is

=> V = π * r² * h,

where V represents the volume, π is a constant (approximately equal to 3.14159), r is the radius, and h is the height of the cylinder.

In the provided information, we are given that the radius of the cylinder is 6 cm (radius = 6 cm) and the volume of the cylinder is 904.78 cm³ (V = 904.78 cm³).

Now, we can rearrange the volume formula to solve for the height (h) of the cylinder. Divide both sides of the formula by (π * r²):

h = V / (π * r²)

Substitute the known values:

h = 904.78 cm³ / (3.14159 * 6²)

h = 904.78 cm³ / (3.14159 * 36)

h = 904.78 cm³ / 113.09724

h ≈ 7.99998 cm

Rounding the answer to the nearest whole number, the height of the cylinder is approximately 8 cm.

To find the area of a circle with a diameter of 6, divide the diameter by 2 to get the radius, then use the formula Area = πr² with the calculated radius, resulting in an area of 28.26.

Using either the exact value of π (pi) or its approximation 3.14, we substitute the radius into the formula to calculate the area.

Using π, the area is:

A = π(3)² = 9π

Using the approximation of 3.14 for π, the area is:

A = 3.14(3)² = 3.14(9) = 28.26

So, the area of the circle is either 9π square units or approximately 28.26 square units if you use 3.14 for π.

angle = arc tangent(6/x)

for x=2 -> angle = 71.565°

Step-by-step explanation:

To find the relation of the distance x and the angle of elevation that you are seeing the airplane, we should use the tangent relation of the angle. The opposite side of the angle is the altitude of the airplane, and the adjacent side of the angle is the distance x.

So we have that:

tangent(angle) = 6/x

angle = arc tangent(6/x)

If we have the value of x = 2, the angle will be:

angle = arc tangent(6/2) = arc tangent(3)

angle = 71.565°

The area of the regular hexagon is 585 square centimeters.

A regular hexagon is a polygon with six equal sides and six equal angles. To find the area of a regular hexagon, you can use the formula:

[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \text{side length}^2 \][/tex]

However, in this case, the apothem (the distance from the center to the midpoint of a side) is given instead of the side length. The relationship between the apothem (\(a\)) and the side length (\(s\)) of a regular hexagon is given by:

[tex]\[ a = \frac{s}{2} \times \sqrt{3} \][/tex]

Rearranging this formula to solve for \(s\), we get:

[tex]\[ s = \frac{2 \times a}{\sqrt{3}} \][/tex]

Substituting this expression for \(s\) into the area formula, we get:

[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \left(\frac{2 \times a}{\sqrt{3}}\right)^2 \][/tex]

Simplifying further:

[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \frac{4 \times a^2}{3} \][/tex]

Canceling out common factors:

[tex]\[ \text{Area} = 2 \sqrt{3} \times a^2 \][/tex]

Now, substituting the given apothem ((a = 15) cm), we find:

[tex]\[ \text{Area} = 2 \times \sqrt{3} \times (15 \, \text{cm})^2 = 585 \, \text{cm}^2 \][/tex]

Therefore, the area of the regular hexagon is 585 square centimeters.

Answer:

15.49 inches

Step-by-step explanation:

Volume of a cylinder is given by

[tex]V=\pi r^{2}h[/tex]

Making h the subject of the formula then

[tex]h=\frac {V}{\pi r^{2}}[/tex]

Where h is the height, V is volume and r is radius. Substituting 24.6 inches for r and 29468 cubic inches for V then

[tex]h=\frac {29468}{\pi 24.6^{2}}=15.493723673378\ in\approx 15.49\ in[/tex]

Therefore, the height is approximately 15.49 inches

The correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).

To find the height of a cylinder with a volume of 29,468 cubic inches (in3) and a radius of 24.6 inches, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.

Plugging in the known values, we get:
29,468 in3 = π(24.6 in)2h

Solving for h, the height of the cylinder, we perform the following steps:

Calculate the base area: Base Area = π(24.6 in)2

Divide the volume by the base area to find the height: h = Volume / Base Area

Calculate the height: h = 29,468 in3 / (π(24.6 in)2)

After performing the calculation, we conclude that the correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).
