Answer:

Reject Null Hypothesis given that  P-value < ∝

Step-by-step explanation:

Applying the Five ( 5 ) step model and assuming ∝ = 0.05

First step : determine the Null hypothesis

H0 : Age and support for Anti-smoking = independent

Second step : Determine the alternate hypothesis

Ha : Age and support for Anti-smoking ≠ independent

Thirdly : Identify significance level ( ∝ ) = 0.05

4th step : Calculate the Test statistic and P-value

Chi-squared test = 36.1429 using excel function

P-value =  1 - CHISQ.DIST(36.1429, 1, TRUE)  < 0.0001

finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that

P-value < ∝

An illustration of the relationship between two sets of data is a scatter plot. A scatter plot's data can occasionally be used to determine a mathematical relationship between two variables. A scatter plot's equation can be determined manually in one of two ways: graphically, or via a method known as linear regression.

How to Make a Scatter Plot

Graph paper can be used to make a scatter plot. Identify the origin, draw the x- and y-axes, and make sure they intersect. Make sure the x- and y-axes have the proper titles as well. Plot each data point on the graph after that. Any patterns between the plotted data sets ought to be clear at this point.

Finding the equation is simple once a line of best fit has been drawn on a scatter graph. y = mx + c is the general formula for a straight line.

where c is the line's y-intercept and m is the line's slope (gradient). Find two places along the line to get the gradient. Let's assume for the purposes of this example that the two points are (1,3) and (0,1). By dividing the difference in the x-coordinates by the difference in the y-coordinates, it is possible to determine the gradient.

In this instance, the gradient is equal to 2. The equation for the straight line up until this point is y = 2x + c.

By swapping the values for, one can get the value for c.

a well-known fact. As an illustration, one of the well-known points is (1,3). Rearrange this for c after plugging it into the equation:

3 = (2 × 1) + c \\ c = 3 - 2 = 13=(2×1)+c\sc=3−2=1

In this instance, the solution is y = 2x + 1.

Answer:

x - 4 yards.

Step-by-step explanation:

Given:

Area of rectangle = 3x^2 - 12x square yards

Width = 3x yards

To find:

Length of rectangle

Solution:

The area of a rectangle is equal to the product of its length and width.

Area of rectangle = Length * Width

Substituting the given values, we get:

3x^2 - 12x = Length * 3x

Length =( 3x^2 - 12x )3x

Length = x-4

Therefore, the length of the rectangle is x - 4 yards.

Answer: The length of the rectangle is x - 4 yards.

Step-by-step explanation:

We can create an equation to solve this word problem, where the variable L = length.

3x  ×  L  = \(3x^2 - 12x\)

We need to solve for the variable L, to find the length of the rectangle.

First lets factor the right side of the equation to make it easier to divide with.

3x  ×  L  = \(3x^2 - 12x\)

We can factor out 3x from the right side of the equation.

3x  ×  L  = 3x(x - 4)

Now we need to get the variable L by itself (isolating the variable). In order to do that, we can divide both sides by 3x.

3x ×  L  = 3x(x - 4)

/3x           /3x

L = x - 4

The length of the rectangle is x - 4 yards.

So, the value of the car after 13 years is approximately $13,330.

In mathematics, an initial value refers to the value of a function or a variable at a specific starting point or initial condition. For example, when solving a differential equation, the initial value is the value of the function at the starting point or initial time.

In the context of calculus, the initial value of a function f(x) at a point x=a is denoted by f(a). In the context of differential equations, the initial value of a function y(x) at a point x=a is denoted by y(a) or y(a) = y0.

he given exponential function can be written as:

\(v(t) = 25,900(0.95)^t\)

where t is the age of the car in years.

To find the initial value of the car, we need to evaluate v(0):

\(v(0) = 25,900(0.95)^0\)

\(v(0) = 25,900(1)\)

\(v(0) = 25,900\)

So, the initial value of the car is $25,900.

To find the value of the car after 13 years, we need to evaluate v(13):

\(v(13) = 25,900(0.95)^{13}\)

v (13) ≈ 13,330

Step-by-step explanation:

The integral\($\int_{-\infty}^{\infty} f(x)^2 dx$\) expresses the volume of the solid, where f(x) is the side length of the square cross sections taken perpendicular to the x-axis in the region r.

The given integral \($\int_{-\infty}^{\infty} f(x)^2 dx$\) expresses the volume of the solid whose base is the region r. The integral is calculated by taking the cross sections of the solid perpendicular to the x-axis and consider them as squares. The side length of each square is denoted by f(x). The integral is calculated over the region r, which is the base of the solid. This integral is the sum of the areas of all the squares, which is equivalent to the volume of the solid. The integral is calculated by taking the lower limit of integration as\($-\infty$\) and the upper limit of integration as\($\infty$\). Hence, the integral \($\int_{-\infty}^{\infty} f(x)^2 dx$\) expresses the volume of the solid with the base region r and square cross sections.

Originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

Originality refers to the quality of being unique, new, and innovative. It involves creating something that has not been seen or experienced before. The best description of originality is that it is having a low probability and being unique.

An original idea, product, or work of art is something that has not been copied or imitated from others. It represents a new perspective or approach that can offer a fresh insight into a problem or challenge. Originality requires a high level of creativity, imagination, and inspiration, as well as a willingness to take risks and explore new possibilities.

Nonobviousness is also an important factor in originality. It means that the idea or invention is not something that would be obvious to someone skilled in the same field or industry. In other words, an original idea should not be something that could be easily predicted or anticipated.

Special or interesting are also characteristics of originality, but they are not sufficient to define it. An idea or product can be special or interesting without being truly original. For example, a new flavor of ice cream may be interesting, but it may not be original if it has already been created by someone else.

Convergent thinking, on the other hand, involves finding a single solution to a problem. It is the opposite of divergent thinking, which involves generating multiple ideas and possibilities. Convergent thinking is important for finding effective solutions to problems, but it is not the same as originality.

In conclusion, originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

You take the area of the circle which is pie*r^2

This is the expression for the orthogonal projection of v onto the plane P characterized by θ and θ_0 is, proj_P(v) = [v₁ - (v₁ cos(θ) + v₂ sin(θ)) cos(θ), v₂ - (v₁ cos(θ) + v₂ sin(θ)) sin(θ)]

Let's assume that the plane P is given by the normal vector n = [cos(θ), sin(θ)], and a point on the plane is given by r = [cos(θ_0), sin(θ_0)].

To find the orthogonal projection of a point v onto P, we need to find the component of v that lies in the direction of the normal vector n, and then subtract that component from v. This can be done using the dot product of v and n:

proj_n(v) = (v · n) / ||n||^2 × n

where · denotes the dot product, ||n|| is the length of n, and proj_n(v) is the projection of v onto n.

To find the projection of v onto P, we need to subtract the projection of v onto n from v:

proj_P(v) = v - proj_n(v)

= v - (v · n) / ||n||^2 × n

Substituting the expressions for n and θ, we get:

proj_P(v) = v - (v · [cos(θ), sin(θ)]) / (cos^2(θ) + sin^2(θ)) × [cos(θ), sin(θ)]

= v - (v₁ cos(θ) + v₂ sin(θ)) / (cos^2(θ) + sin^2(θ)) × [cos(θ), sin(θ)]

= v - (v₁ cos(θ) + v₂ sin(θ)) / 1 × [cos(θ), sin(θ)]

= [v₁ - (v₁ cos(θ) + v₂ sin(θ)) cos(θ), v₂ - (v₁ cos(θ) + v₂ sin(θ)) sin(θ)]

where v₁ and v₂ are the components of v in the x and y directions, respectively. This is the expression for the orthogonal projection of v onto the plane P characterized by θ and θ_0.
