Answer:

(a) Confirmation bias

(b) Likely less than actual proportion of families who support the proposal

(c) Random sample

(d) Nonresponse bias

Step-by-step explanation:

In confirmation bias, the researcher already has and intends to prove an assumption about the effect the of a treatment before carrying out the survey, such that the survey or research is tries to dictate to the participants in the survey about the desired outcome

In the question, the belief of the researcher is expressed to the participants in a form of brief at the start of the survey which is attempting to influence the responses to the survey, such that the actual result should be less than what was observed.

The surface area of that part of the plane 10x+7y+z=4 that lies inside the elliptic cylinder \(\frac{x^2}{25} +\frac{y^2}{9}\) is 15π√150 and this can be determined by using the given data.

We are given the two equations are:

10x + 7y + z = 4---------(1)

\(\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)\)

equation(1) is written as

z = 4 - 10x - 7y-----------(3)

The surface area is given by the equation:

A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)

compare equation(4) with equation(3) we get the values of ∂f/∂x and

∂f/∂y

∂f/∂x = -10

∂f/∂y = -7

substitute these values in equation(4)

A(S) = ∫∫√[(-10)² + (-7)² + 1]dA

A(S) = ∫∫√[100 + 49 + 1]dA

A(S) = ∫∫√[150]dA

A(S) = √150 ∫∫dA

Where ∫∫dA is the elliptical cylinder

From the general form of an area enclosed by an ellipse with the formula;

comparing x²/a² + y²/b² = 1  with x²/25 + y²/9 = 1, from that we get the values of a and b

a = 5 and b = 3

So, the area of the elliptical cylinder = πab

Thus;

A(S) = √150 × π(5 × 3)

A(S) = 15π√150

Step-by-step explanation:

The n th term of an AP is

\(a_{n}\) = a₁ + (n- 1)d

where a₁ is the first term and d the common difference

Here d = 5, then

a₁₈ = a₁ + 17d = a₁ + 85

If a regression line is parallel to the horizontal axis of a scattergram, it means that there is no relationship between the two variables being plotted. In this case, the slope (b) of the regression line would be zero.

When we perform a linear regression analysis, we are trying to find the best-fitting line that represents the relationship between the independent variable (x) and the dependent variable (y). The slope (b) of this line represents the rate of change between the two variables. If the regression line is parallel to the horizontal axis, it suggests that there is no change in the dependent variable for any change in the independent variable.

The general equation for a linear regression line is:

y = a + bx

Here, "a" represents the y-intercept (the value of y when x is zero) and "b" represents the slope. When the regression line is parallel to the horizontal axis, it means that the line is perfectly horizontal, and the dependent variable (y) does not change as the independent variable (x) changes.

Mathematically, this can be represented as:

y = a + 0x

y = a

In this equation, the slope (b) is zero because there is no change in the dependent variable (y) for any change in the independent variable (x). The value of y remains constant, resulting in a horizontal line parallel to the x-axis.

To further explain, when the slope (b) is zero, it indicates that there is no linear relationship between the two variables. In a scattergram, the points are spread out randomly and do not follow any specific trend or pattern. Each value of x corresponds to a single value of y, and these values do not exhibit any systematic change as x increases or decreases.

Visually, a regression line that is parallel to the horizontal axis will appear as a flat line, with all points lying on the same y-value. This indicates that the dependent variable does not depend on the independent variable and remains constant across all values of x.

In conclusion, when a regression line is parallel to the horizontal axis in a scattergram, the slope (b) of the line is zero. This indicates that there is no linear relationship between the variables being analyzed, and the dependent variable does not change as the independent variable varies. The absence of a slope suggests that the two variables are not related in a linear fashion, and the scattergram does not exhibit any pattern or trend.

Answer:

Step-by-step explanation:

You want the amplitude, period, phase shift, range, and y-intercept of the function ...

  f(x) = 3sin(3x -3π/2) -2

The amplitude of the parent sine function is 1. The period of it is 2π. When the function has a different amplitude and period, it looks like ...

  f(x) = (amplitude)·sin(2πx/(period))

Comparing this form to ...

  f(x) = 3sin(3x)

we find the multiplier is 3 and the argument of the sine function is 3x. This tells us ...

  amplitude = 3

  (2πx/period) = 3x   ⇒   period = (2πx)/(3x) = 2π/3

When a function is translated h units to the right, and k units up, it becomes ...

  f(x -h) +k

Looking at the attached graph of the given function, we see the point that is (0, 0) on the parent function is translated to (π/2, -2) on the graph. Then our translated function is ...

  f(x -π/2) -2 = 3sin(3(x -π/2)) -2

The amount of horizontal translation is the phase shift, which is π/2.

The range of the function is the interval between (and including) the maximum and minimum. Since the amplitude is 3 and the vertical shift is -2, the range is -2±3 = -5 to +1. In interval notation, the range is [-5, 1].

The y-intercept is the value of y when x = 0. For the given function, that is ...

  f(0) = 3·sin(3·0 -3π/2) -2 = 3·sin(-3π/2) -2 = 3 -2 = 1

The y-intercept is 1.

Step-by-step explanation:

Let the number of $2 price increases be x.

This means that if the price is 10+2x, 42-2x shoes are sold.

So, the revenue is (10+2x)(42-2x).

To maximize profit, we must maximize revenue.

\((10+2x)(42-2x)\\\\=-4x^2 +64x+420\)

The maximum is at \(x=-\frac{64}{2(-4)}=8\), so the price should be 10+2(8)=$26.

the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride is approximately 51.54 degrees.

What is Angle of Elevation?

The angle of elevation is the angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is the angle of elevation.

To find the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride in Disney World, Florida, we can use trigonometry.

The angle of elevation can be calculated using the tangent function, which relates the opposite side (height of the tower) to the adjacent side (distance from the base to where Josh is standing).

Tangent(theta) = Opposite / Adjacent

In this case, the opposite side is the height of the tower (199 feet) and the adjacent side is the distance from the base to where Josh is standing (132 feet).

Tangent(theta) = 199 / 132

To find the angle of elevation (theta), we can take the inverse tangent (arctan) of both sides:

theta = arctan(199 / 132)

Using a calculator, the approximate value of the angle of elevation is:

theta ≈ 51.54 degrees

Therefore, the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride is approximately 51.54 degrees.

Answer:1,500 kg • m/s

Step-by-step explanation:

took the quiz

The momentum of the object after the collision is 1500 kg.(m/s).

Momentum is the product of a particle's mass and velocity. As a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum.

As per the given data:

\(m_A = 200 kg\\v_A = 15 m/s\\m_B = 150 kg\\v_B = -10 m/s\)

Law of conservation of momentum:

Initial momentum = Final momentum

\(m_Av_A + m_bv_b\) =  Final momentum

Final momentum = 200(15) + 150(-10)

= 3000 - 1500

= 1500 kg.(m/s)
