Answer:

  The ratio (center to focus)/(semi-major axis) is the greatest

Step-by-step explanation:

Given various foci coordinates and major axis lengths, you are asked to identify the ellipse with the highest eccentricity.

The eccentricity of an ellipse can be defined as the ratio of distance between foci to the length of the major axis. A high value of eccentricity corresponds to a longer, narrower ellipse.

The attached graph plots the locations of the given foci. They are color coded to correspond with the color of the resulting ellipse. (We have used the given r-value as the semi-major axis, not the major axis.)

The blue focal points (A, A') of the blue ellipse give the "flattest" of the bunch, so corresponds to the highest eccentricity. Its parameters are those of the first answer choice.

If we assume the given r-value is the semi-major axis, the eccentricity represented by each of the answer choices is ...

The numerator in each case is the distance from the center (0, 0) to one focus.

When a pair of dice rolled, the probability that the sum is either a multiple of 3 or a multiple of 4 is 5/9.

If an event A and an event B is independent to each other, then the probability A or B is:

P(A or B) = P(A∪B) = P(A) + P(B)

In the given problem:

The possible outcomes or the sample space of rolling a pair of dice = 6 x 6 = 36.

The maximum sum is 6 + 6 = 12

Multiple 3 or multiple 4 that ≤ 12 is {3, 4, 6, 8, 9, 12}

Possible outcomes for Sum = 3 are 1 + 2 and 2 + 1

Hence,

P(3) = 2/36

Possible outcomes for Sum = 4 are 1 + 3, 3 + 1, 2 + 2

Hence,

P(4) = 3/36

For Sum = 8,  2 + 6, 6 + 2, 3 + 5, 5 + 3, 4 + 4

Hence,

P(8) = 5/36

Similarly,

P(6) = 5/36

P(9) = 4/36

P(12) = 1/36

Therefore,

P(Multiple 3 or multiple 4) = P(3, 4, 6, 8, 9, 12)

                                          = 2/36+3/36+5/36+5/36+4/36+1/36

                                          = 20/36

The least-square regression line between data fuel efficiency and speed is  In(Fuel Efficiency) = 1.437 + 0.541 In(Speed).  The fuel efficiency when the speed 60 mph is 38.55 mpg

Least square regression is a representation of data in a linear equation:

y = ax + b

where x, y are data variables.

The least-squares regression line is obtained by minimizing  the distance from  regression line to each data points.

In the given problem, the given least-squares regression line is:

In(Fuel Efficiency) = 1.437 + 0.541 In(Speed)

In this case,

y =  In(Fuel Efficiency)

x = ln(Speed)

Where ln is the natural logarithmic operator.

When speed = 60 mph, then,

In(Fuel Efficiency) = 1.437 + 0.541 In(60)

In(Fuel Efficiency) = 1.437 + 2.215

In(Fuel Efficiency) = 3.65

Fuel efficiency = e^(3.65) = 38.55

Hence, the fuel efficiency when the speed 60 mph is 38.55 mpg

Your question is incomplete, but most probably your question was:

 Where C is counterclockwise around the triangle with vertices (0, 0),

(1, 0)  and (1, 4)

Our first line integral is

L₁ = ₁∫₍₀, ₀₎ ⁽¹ ⁰⁾ xy dx + x² y³ dy

The equation of this line is y = 0,  x varies from 0 to 1.

L₁ = 0

Our second line integral is

L₂ = ₁∫₍₁, ₀₎ ⁽¹ ⁴⁾ xy dx + x² y³ dy

The equation of this line is x = 0  and y varies from 1 to 4.

L₂ = 64/3

The third line integral is

L₃ = ∫₁⁰ xy dx + x² y³ dy

The equation of this line is y = 4x  and x varies from 0 to 1.

L₃ = -4

The value of the line integral is

L = L₁ + L₂ + L₃ = 0 + 64/3 + (-4) = 52/3

b) The second part requires the use of Green's Theorem to evaluate:

This is given by:

∫c Pdx + Qdy = ∫ ∫ R Qy - Px dA

∫c xy dx + x² y³ dy = ∫ ∫R 3x² y² - ydA

We choose our region of integration parallel to the y-axis.

∫c xy dx + x² y³ dy

The angles in a circle are called inscribed angles, which can be formed by passing the line through the center.

What is a Central Angle?

The central angle is the angle that a circle's arc occupies in its center. The arms of the central angle are formed by the radius vectors. In other words, it's an angle whose vertex is the center of a circle and whose arms, which have the circle's two radii as their arms, cross at two separate positions. These two points make an arc when they are combined. The angle that this arc at the circle's center subtends is known as the central angle.

An arc's angle at the circle's center is twice as large as its angle at any other point along the circle's circumference. the angle subtended by the arc in the opposite segment of the circle is twice as large as the angle at the center of the circle.

When two chords intersect on a circle, an inscribed angle is an angle that is created inside the circle. It can alternatively be described as the angle formed at a particular point on a circle by two specified points.

Hence,

There is sufficient evidence at the α = 0.05 level to conclude that less than 20% of the parts are being painted with an error.

The calculated P-value of approximately 0.023, which is less than the significance level of 0.05.

The P-value indicates the probability of observing a test statistic as extreme as or more extreme than the observed value of -2.00 under the null hypothesis.

Since the P-value is smaller than the significance level, we reject the null hypothesis and conclude that the proportion of parts with an error is significantly less than 20%.

The fact that 16% is less than 20% also supports this conclusion.
