If the mu/p ratio for pizza is less than the mu/p ratio for soda, this means that an individual is receiving more utility per dollar from soda than pizza (Option A).

In other words, the marginal utility of spending one more dollar on soda is greater than spending one more dollar on pizza. This doesn't necessarily mean that the price of pizza is lower than the price of soda (Option B) or that the price of pizza is lower than the price of coke (Option C), as the prices of the two goods could be equal or have different relative prices. It also doesn't mean that the MU of pizza is lower than the MU of soda (Option D), as the MU of each good could be different regardless of their price ratios.

The final answer is: Option A

Answer:

A)n= 703.96

B)n= 602.308

Step by step Explanation:

Given that you want to be 99% confident that the sample percentage is within 3.1 percentage points of the true population percentage.

Then z/2 = 1.645

And M = 3.1% = 0.031

A)Nothing is known therefore,

p = q = 0.50

E=0.031

For 90% confidence, z = 1.645

n = (zα/₂)²(p)(1-p)/M²

n= 1.645²× 0.5 × 0.5/0.031²

n= 703.96

Therefore, 703.96randomly selected air passengers must be​ surveyed to be 99%

B)we know that recent surveys surgest that about 38% of all air passengers prefer an aisle seat, thus p = 35% = 0.35

n = (zα/₂)²(p)(1-p)/M²

n= (1.645²× 0.31 × 0.69)/0.031²

n= 602.308

Hence, 602.308 randomly selected air passengers must be​ surveyed to be 90% confident that the sample percentage is within 3.1 percentage points of the true population percentage.

Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

To find the Taylor polynomials centered at x = 0 for the function f(x) = 16tan(x), we can use the Taylor series expansion for the tangent function and truncate it to the desired degree.

The Taylor series expansion for tangent function is:

tan(x) = x + (1/3)x^3 + (2/15)x^5 + (17/315)x^7 + ...

Using this expansion, we can find the Taylor polynomials of degree 2 and 3 centered at x = 0:

Degree 2 Taylor polynomial:

P2(x) = f(0) + f'(0)(x - 0) + (1/2!)f''(0)(x - 0)^2

= 16tan(0) + 16sec^2(0)(x - 0) + (1/2!)16sec^2(0)(x - 0)^2

= 0 + 16x + 8x^2

Degree 3 Taylor polynomial:

P3(x) = P2(x) + (1/3!)f'''(0)(x - 0)^3

= 0 + 16x + 8x^2 + (1/3!)(48sec^2(0)tan(0))(x - 0)^3

= 16x + 8x^2

Therefore, the Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

Answer:

Width (w) = 72 yds

Length (L) = 217 yds

Step-by-step explanation:

Let L represent the length.

Let w represent the width.

From the question given above:

Perimeter (P) = 578 yds.

Length (L) is one more than three times the width (w). This can be written as. Follow:

three times the width (w) = 3w

Therefore, the length (L) is given by:

L = 1 + 3w

Next, we shall determine the value of length (L) and width (w). This can be obtained as follow:

Recall:

Perimeter of rectangle is given by:

P = 2(L + w)

P = 2L + 2w

Perimeter (P) = 578 yds.

Length (L) = 1 + 3w

Width (w) = w

P = 2L + 2w

578 = 2(1 + 3w) + 2w

Clear bracket

578 = 2 + 6w + 2w

578 = 2 + 8w

Collect like terms

578 - 2 = 8w

576 = 8w

Divide both side by 8

w = 576/8

w = 72

Therefore, the width is 72 yds

L = 1 + 3w

w = 72

L = 1 + 3(72)

L = 1 + 216

L = 217

Therefore, the length is 217 yds.

The dimensions of the garden is given below:

Width (w) = 72 yds.

Length (L) = 217 yds.

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

x= total minutes -4    the 1st 4 minutes are included in the .30

The solution to the system of equations is x = 9/7 and y = 11/7.

The given system of equations is:

3x + 2y = 7 (Equation 1)

x = 6 - 3y (Equation 2)

To find the solution, we will substitute the value of x from Equation 2 into Equation 1.

Substitute x = 6 - 3y into Equation 1:

3(6 - 3y) + 2y = 7

Now, simplify the equation:

18 - 9y + 2y = 7

-7y = 7 - 18

-7y = -11

Next, solve for y by dividing both sides by -7:

y = (-11) / (-7)

y = 11/7

Now that we have the value of y, we can find the value of x using Equation 2:

x = 6 - 3(11/7)

Calculate x:

x = 6 - 33/7

x = 42/7 - 33/7

x = (42 - 33) / 7

x = 9/7

The solution (x, y) = (6, -11/2) should be selected.

To find the solution to the system of equations:

3x + 2y = 7 (Equation 1)

x = 6 (Equation 2)

We can substitute the value of x from Equation 2 into Equation 1:

3(6) + 2y = 7

Simplifying the equation:

18 + 2y = 7

Subtracting 18 from both sides:

2y = 7 - 18

2y = -11

Dividing both sides by 2:

y = -11/2

So the value of y is -11/2.

Now, substitute the value of y into Equation 2 to find the value of x:

x = 6

Therefore, the solution to the system of equations is x = 6 and y = -11/2.

Quadrants are the four regions of the Cartesian plane that are separated by the x-axis and the y-axis. They are numbered counterclockwise starting from the positive x-axis, which is also known as the 0-degree axis. Therefore, if sec >0 and sin <0, the point lies in the fourth quadrant.

The first quadrant is where both the x and y coordinates are positive, the second quadrant is where the x coordinate is negative and the y coordinate is positive, the third quadrant is where both the x and y coordinates are negative, and the fourth quadrant is where the x coordinate is positive and the y coordinate is negative.

To determine in which quadrant a point lies based on the signs of the trigonometric functions, we can use the following rules:

If sin > 0 and cos > 0, the point lies in the first quadrant.

If sin > 0 and cos < 0, the point lies in the second quadrant.

If sin < 0 and cos < 0, the point lies in the third quadrant.

If sin < 0 and cos > 0, the point lies in the fourth quadrant.

In this case, we are given that sec > 0 and sin < 0. We know that sec is the reciprocal of cos, so sec > 0 implies that cos > 0. We also know that sin < 0, which means that the y coordinate of the point is negative.

Based on the rules above, we can conclude that the point lies in the fourth quadrant. This is because sin is negative (so the point is below the x-axis) and cos is positive (so the point is to the right of the y-axis), which is the condition for a point to lie in the fourth quadrant.
