The percentage of people between the ages of 21 and 34 who prefer football are: 25%

A random sample is a subset of a larger population that is chosen so that every person or thing has an equal chance of being chosen.

To find the percentage, we need to find the number of people between 21 and 34 who prefer football and divide by the total number of people in that age range:

Number of people between 21 and 34 who prefer football: 9

Total number of people between 21 and 34 are:  36

So the percentage of people between the ages of 21 and 34 who prefer football are:

⇒ (9 / 36) x 100%

⇒ 25%

Rounding to the nearest whole number, the answer is 25%

Complete figure-

To cover a 2000 sq ft wall, we will need 5 gallons of paint.

what is area?

Area is the measure of the size of a two-dimensional surface or region, expressed in square units. It is a fundamental concept in geometry and is used to quantify the amount of space inside a shape, such as a square, rectangle, triangle, or circle. The unit of measurement for area varies depending on the system used, but in the International System of Units (SI), the standard unit of area is the square meter (m²). In everyday life, we often use other units of area such as square feet, square inches, or square centimeters.

To find the conversion factor, we need to divide the number of square feet by the number of square feet covered by one gallon of paint:

Conversion factor = 1 gallon / (400 sq ft/gallon)

So, for a wall that is 2000 sq ft, we can use this conversion factor to find the number of gallons of paint needed:

Number of gallons = (2000 sq ft) / (400 sq ft/gallon) = 5 gallons

Therefore, to cover a 2000 sq ft wall, we will need 5 gallons of paint.

Answer:

The residual is the difference between the actual y-value and the predicted y-value on a regression line. Since no table or equation is provided, we cannot calculate the exact residual. However, I can explain the concept to you.

Step-by-step explanation:

In general, to calculate the residual, we would need a regression equation or a line of best fit. This equation allows us to predict the y-values for different x-values. Then, we can compare the predicted values to the actual values given in the table to find the residuals.

If you have the regression equation or the line of best fit, I can help you calculate the residual for a specific x-value.

The translation used to create the image is 3 units to the right, as each point of the original polygon was moved 3 units to the right to obtain the corresponding point of the image polygon.

What is Polygon?

Geometry defines a polygon as a closed shape composed of continuous line segments, or sides, that do not intersect.

Translation is a transformation in geometry that moves an object without changing its shape, size, or orientation. It involves sliding an object along a straight line in a certain direction and distance.

According to given information:

To determine the translation used to create the image, we can observe the original and transformed polygons and look for changes in their positions. The vertices of the original polygon ABCD are (1,5), (3,1), (7,1), and (5,5), while the transformed polygon A'B'C'D' has vertices (8,5), (10,1), (14,1), and (12,5).

Comparing the vertices of the two polygons, we notice that all of the points have been shifted 7 units to the right to obtain the transformed image. This means that every x-coordinate of the original polygon has been increased by 7, which can be written as a translation vector (7, 0).

Therefore, the translation used to create the image is 7 units to the right.

A reduced radical form is a way of simplifying expressions that contain radicals such as square roots and cube roots, as much as possible. In a reduced radical form, the radical is simplified to its lowest possible terms.

To obtain the reduced radical forms of the expresions, we can proceed with the workings:

1. 3^(√4/9m^2) = 3^(2/3 * 1/3√4m^2) (since √4 = 2)

= (3^(2/3))^(1/3√4m^2)

= (3^(2/3))^(2/3m)

√700 = √(100 * 7) = 10√7

√112 = √(16 * 7) = 4√7

√63 - √700 - √112 = 3√7 - 10√7 - 4√7

= -11√7

3. (a^2b^8/a^1/3)^3/4 = (a^2/1/3√a)^3/4 * b^8^3/4

Answer: Let's start by calculating the probability that an 18-year-old driver is involved in an accident:

P(accident) = 124/2000 = 0.062

Let's assume that the insurance company pays the full cost of the accident, which is $15,000. Then the expected cost of covering one 18-year-old driver is:

Expected cost = P(accident) x Cost of accident = 0.062 x $15,000 = $930

If the insurance company wants to make a 20% profit on policies, they need to charge a premium that covers their expected cost plus their desired profit. The premium, denoted by P, can be calculated as follows:

P = (Expected cost + Desired profit) / (1 - Profit margin)

where Profit margin is the percentage of the premium that represents the profit. In this case, Profit margin is 20%, or 0.20.

Substituting the values we have calculated, we get:

P = ($930 + 0.20 x $930) / (1 - 0.20)

= $1,236.00

Therefore, the insurance company should charge 18-year-old drivers a premium of $1,236.00 to make a 20% profit on policies.

Step-by-step explanation:

The expression is 16 times as large as 18,233 — 4,006 (B) 16(18,233 - 4,006).

The expression (18,233 - 4,006) + 16 represents the sum of the difference between 18,233 and 4,006 (which is 14,227) and 16 times that difference.

To break it down further:

First, we calculate the difference between 18,233 and 4,006, which is 14,227.

Then, we multiply 14,227 by 16 to get 227,632.

Finally, we add the original difference of 14,227 to the product of 16 and the difference to get the final answer, which is 241,859.

The x-axis is where the circle centre is located. Three units make up the circle's radius. This circle's radius coincides with the radius of the circle whose equation is x² + y² = 9.

The y coordinate of a circle's centre will be 0 if the circle's centre is on the x-axis. The circle's equation will therefore have the generic form x2 + y2 + 2gx + c = 0, where g and c are constants.

Circle's standard equation is written as:

x²+y²+2gx+2fy+C=0

Centre is (-g, -f)

radius = √g²+f²-C

Given a circle whose equation is : x²+y²-2x-8=0

Get the centre of the circle

2gx = -2x

2g = -2

g = -1

Similarly, 2fy = 0

f = 0

Centre = (-(-1), 0) = (1, 0)

This demonstrates circle's centre is on the x-axis.

r = radius = √g²+f²-C

radius = √1²+0²-(-8)

The circle has a radius of three units.

Answer:

3.6 meters.

Step-by-step explanation:

We can use the concept of similar triangles to solve this problem. The ratio of the height of the first tree to its shadow length is the same as the ratio of the height of the second tree to its shadow length.

Let h1 be the height of the first tree, s1 be its shadow length, h2 be the height of the second tree, and s2 be its shadow length.

For the first tree: h1/s1 = 3/15

For the second tree: h2/18 = 3/15

Solving for h2:

h2 = (18 * 3) / 15 = 3.6 meters

Therefore, the height of the second tree is 3.6 meters.

Answer:  The question is asking us to find the derivative of the function f(x), but the function given is g(x). Therefore, we will assume that the question is asking us to find the derivative of g(x) and proceed accordingly.

To find the derivative of g(x), we need to apply the power rule and the sum rule of derivatives. The power rule states that if f(x) = x^n, then f'(x) = nx^(n-1), and the sum rule states that if f(x) = u(x) + v(x), then f'(x) = u'(x) + v'(x).

Using these rules, we can find the derivative of g(x) as follows:

g(x) = 3x² + 7x - 1

g'(x) = (3x²)' + (7x)' - (1)'

g'(x) = 6x + 7 - 0

g'(x) = 6x + 7

Therefore, the derivative of g(x) is g'(x) = 6x + 7.

Using natural logarithm to solve equations:

2eˣ = 4

eˣ = 4/2

eˣ = 2   (take "ln" of both sides to get rid of "e")

x = ln 2

x = 0.693

eˣ = 72

x = ln 72

x = 4.277

e⁴ˣ = 25

4x = ln 25

x = (ln 25)/4

x = 0.805

e³ˣ = 124

3x = ln 124

x = (ln 124)/3

x = 1.607

PART 2

ln(x -3) = 2    (take "e" of both sides to get rid of "ln")

x - 3 = e²

x = e² + 3

x = 7.389 + 3

x = 10.389
