Draw a model to show 3/4 of 16.

Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that there is evidence to suggest that a majority of U.S. adults wear a helmet when they ride their bike.

The randomization distribution will show the proportion of people who wear helmets in each of the 1000 samples.

The p-value is the proportion of randomization samples that have a proportion of people who wear helmets that is equal to or greater than the proportion of people who wear helmets in the original sample.

In this case, the p-value is 0.04. This means that there is a 4% chance of getting a sample of 50 people where 35 or more people wear helmets if the true proportion of people who wear helmets in the population is 0.5.

Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that there is evidence to suggest that a majority of U.S. adults wear a helmet when they ride their bike.

Answer:

x = 5.7

Step-by-step explanation:

Use the pythagorean theorem, which says a^2+b^2 = c^2 where c is the hypotenuse (longest side of a right triangle, always opposite the 90 degree right angle).

7^2 + x^2 = 9^2

49 + x^2 = 81

x^2 = 32

now take the square root of both sides

x = 5.65685424949

Round to the nearest tenth.

x = 5.7

Answer:

5.7

Step-by-step explanation:

x^2 + 7^2 = 9^2

x^2 + 49 = 81

x^2 = 81 - 49

x^2 = 32

x = the square root of 32

x = 5.657

The arrangement of the side length of the triangles from the least to the greatest is DF <  DE < EG <  EF <  GF.

The arrangement of the lengths of the triangle from the least to the greatest is determined as follows;

The size of the length of a triangle increases as the size of the angle opposite to the length increases.

That is the greater the size of the angle opposite the side length of a triangle, the greater the size of the side length of the triangle.

From the given diagram, we can arrange the size of the side length of the triangle as follows;

angle D = 180 - (57 + 58 )

angle D = 65⁰ (this is opposite to length EF)

So the arrangement of the side length of the triangles are;

length DF < Length DE < length EG < length EF < length GF

Answer:

64 percent

Step-by-step explanation:

because there is 24 sq and 100 divided by 24 is 4, 4 times 16 is 64

Asia is larger than North America by approximately 8.0 x 10⁶ square miles.

The difference in area between Asia and North America is calculated as follows;

Difference in area = Area of Asia - Area of North America

Difference in area  = 1.74 x 10⁷ mi² - 9.4 x 10⁶ mi²

The difference in the area between Asia and North America is calculated as

= 1.74 x 10⁷ mi² - 9.4 x 10⁶ mi²

= 8.0 x 10⁶ mi²

Thus, The difference in area between Asia and North America is 8.0 x 10⁶ mi².

Step-by-step explanation:

I believe that the biggest reason for the general upward trend in the stock price is expansion. Amazon has expanded their company immensely over the last 5 years. They have also expanded into different markets such as drones, gaming, cloud streaming, video streaming, etc. All of these expansions and acquisitions have been incredibly profitable for Amazon and therefore reflect on the stock price. This also gives investors faith that the future of the company will continue growing which causes them to buy more stocks and therefore increase the price.

Answer:

Step-by-step explanation:

The best estimate of the number of centimeters (cm) in 1 yard is; Yard ⇒ feet ⇒ inches ⇒ centimeters

If we have to determine the number of centimeters in 1 yard, the best way is;

Here we convert  yard to feet = 1 yard = 3 ft

Then, we convert ft to inches = 1 ft = 12 inches

                                                  3 ft = 3 × 12 = 36 inches

Now, we convert inches to centimeters = 1 inch = 2.54 cm

                                            36 inches = 36 × 2.54 = 91.44 cm

Therefore, the best path is Yard to feet to inches to centimeters

V(x)=1000x^3 cubic millimeters is the answer

Hence, a new function for the volume of the cube in cubic millimeters is [tex]V(x)=1000x^3[/tex].

What is the volume of cube?

The volume of a cube is defined as the total number of cubic units occupied by the cube completely.

A cube is a three-dimensional solid figure, having six square faces. Volume is nothing but the total space occupied by an object.

Here given that,

The volume of a cube, in cubic centimeters, is given by the function [tex]V(x) = x^3[/tex], where [tex]x[/tex] is the side length of the cube in centimeters.

As, [tex]1[/tex] centimeter=[tex]10[/tex]millimeters.

If the side is [tex]x[/tex] then the side in millimeter is [tex]10x[/tex].

So, we have [tex]x^3[/tex] which would be [tex](10x)^3[/tex]

[tex](10x)^3=1000x^3[/tex]

John William will receive a total dividend of $43.70.

The value of John William's investment in Peixotto Media, including dividends, is $3,216.95.

a. John William owns a total of 125 + 312 = 437 shares in Peixotto Media. If the company is paying a cash dividend of 10 cents per share, then John William's total dividend income will be:

437 shares x $0.10 per share = $43.70

Therefore, John William will receive a total dividend of $43.70.

b. If John William owns 437 shares in Peixotto Media and the current stock price is $7.25 per share, then the value of his investment in the company (excluding dividends) is:

437 shares x $7.25 per share = $3,173.25

If we add the dividend income of $43.70 to this value, then the total value of John William's investment in Peixotto Media is:

$3,173.25 + $43.70 = $3,216.95

For the "regression-line",  Ŷ = -6 + 0.41(X), the predicted value,

(a) when X=25 is 4.25,

(b) when X=50 is 14.50,

(c) when X=75 is 24.75.

The "Regression-Line", is Ŷ = -6 + 0.41(X), we can make predictions for the value of Y (the dependent variable) for different values of X (the independent variable).

(a) To predict the value of "Y" when X = 25, we substitute 25 into the regression line equation:

Ŷ = -6 + 0.41(25)

Ŷ = -6 + 10.25

Ŷ = 4.25

So, the predicted value of Y when X = 25 is 4.25.

(b) To predict the value of Y when X = 50, we substitute 50 into the regression line equation:

Ŷ = -6 + 0.41(50)

Ŷ = -6 + 20.50

Ŷ = 14.50

So, the predicted value of Y when X = 50 is 14.50.

(c) To predict the value of Y when X = 75, we substitute 75 into the regression line equation:

Ŷ = -6 + 0.41(75)

Ŷ = -6 + 30.75

Ŷ = 24.75

So, the "predicted-value" of Y when X = 75 is 24.75.

The lines intersect at only one specific point (-5, 9)

The correct answer is: There is one unique solution (-5, 9).

When two straight-line equations intersect at a point, it means that there is one unique solution to the system of equations. In this case, the point of intersection is (-5, 9), which indicates that the system has a single solution. This means that there is a unique set of values for the variables that satisfy both equations simultaneously.

If the system had no solution, it would mean that the two lines are parallel and will never intersect. However, since the lines in the given system intersect at (-5, 9), it implies that there is a solution.

Alternatively, if the system had infinitely many solutions, it would mean that the two equations represent the same line. In this case, the lines intersect at every point along their entire length, resulting in an infinite number of solutions. However, the fact that the lines intersect at only one specific point (-5, 9) indicates that there is one unique solution to the system of equations.

The value of angle LAF in the intersecting chords is determined as  104⁰.

The value of angle LAF is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

Also this theory states that arc angles of intersecting secants at the center of the circle is equal to the angle formed at the center of the circle by the two intersecting chords.

m∠LAF = ¹/₂ (arc LF + arc YS)

From the diagram, we have arc LF = 160⁰ and YS = 48⁰

m∠LAF = ¹/₂ (160 + 48)

m∠LAF = 104⁰

Thus, the value of angle LAF is calculated by applying intersecting chord theorem.

The circumference of the circle whose diameter is 2x + 2 is (44x + 44)/7

The formula for the circumference of a circle is 2πr

r = radius of the circle

Diameter of circle = radius  of circle × 2

The radius of the circle = ( diameter of the circle ) / 2

The radius of circle = (2x+2)/2

Taking 2 commons from 2x + 2

we get 2( x + 1 )

The radius of circle = 2(x+1)/2

The radius of the circle = x + 1

Circumference =  2 × 22/7 × (x+1)

Circumference = 44(x+1)/7

Circumference = (44x + 44)/7

Or in the form of π circumference can be written as (2x + 2)π
