Bayes' Theorem is a mathematical theorem that enables the revision of prior probabilities based on new information or evidence.

This theorem is widely used in statistics, machine learning, and other fields that deal with uncertainty and probabilistic reasoning. Contrary to the first option mentioned in the question,

Bayes' Theorem can be used when conditional probabilities are known, and it enables the calculation of posterior probabilities, which is the probability of a hypothesis or event given the available evidence.

Therefore, the third option is correct; Bayes' Theorem enables the use of sample information to revise prior probabilities. This theorem is highly valuable because it allows the integration of new data or knowledge into the decision-making process,

which can lead to more accurate predictions and better-informed decisions. In summary, Bayes' Theorem is a powerful tool that requires knowledge of probabilities and enables the calculation of posterior probabilities based on new evidence or information.

By combining prior probabilities with likelihoods (based on new data), we can calculate posterior probabilities, which represent our updated knowledge.

This process is crucial in making informed decisions in various fields, such as data science, finance, and medical diagnosis.

At an angle of 270 degrees (or 3π/2 radians) on a circle with a radius of 2 and center at (0, 0), the x-coordinate is 0 and the y-coordinate is -2.

To find the x and y coordinates at an angle of 270 degrees (or 3π/2 in radian measure) on a circle of radius 2 with center (0, 0), we can use the trigonometric definitions of sine and cosine.

The x-coordinate (x-value) represents the horizontal position on the circle, while the y-coordinate (y-value) represents the vertical position.

For a point on the unit circle (circle with radius 1) at a given angle θ, the x-coordinate is given by cos(θ) and the y-coordinate is given by sin(θ).

In this case, the circle has a radius of 2, so we need to multiply the cosine and sine values by 2 to get the x and y coordinates, respectively.

Using the angle 270 degrees (or 3π/2 in radian measure):

x-coordinate = 2 * cos(3π/2)

y-coordinate = 2 * sin(3π/2)

Evaluating these expressions:

x-coordinate = 2 * cos(3π/2) = 2 * 0 = 0

y-coordinate = 2 * sin(3π/2) = 2 * (-1) = -2

Therefore, at an angle of 270 degrees (or 3π/2 radians) on the circle of radius 2 with center (0, 0), the x-coordinate is 0 and the y-coordinate is -2.

The dimensions of the box with the least surface area are x = 4 and h = 2.5.

2) Equation of the tangent line to the hyperbola

The given equation is 4x2 − y2 = 32.

We have to find the equation of the tangent to this hyperbola at (3, −2).

First of all, we need to find the slope of the tangent line at the given point.

We differentiate the given equation with respect to x and get

8x − 2y(dy/dx) = 0

Thus, the slope of the tangent line = dy/dx

= 8x/2y

= 4x/y.

Now, we know that the point-slope form of the equation of a line is y − y1 = m(x − x1).

Plugging in the given values, we get

y + 2 = (4(3)/−2)(x − 3)

Simplifying this equation, we get

y = −2x/3 − 2.

This is the equation of the tangent line to the hyperbola 4x2 − y2 = 32 at the point (3, −2).

3) Dimensions of the box with least surface area

A square open box with a square base of side x and height h will have volume V = x2

h = 32.

Therefore, we have

h = 32/x2.

Substituting this value in the equation for surface area, we get

S = x2 + 4xh

= x2 + 4x(32/x2)

= x2 + 128/x.

We need to find the value of x that minimizes S.

We can do this by differentiating S with respect to x and equating it to 0.

dS/dx = 2x − 128/x2

= 0

Multiplying both sides by x2, we get

2x3 − 128 = 0

Thus, x3 = 64, or x = 4.

Therefore, the dimensions of the box with the least surface area are x = 4 and h = 2.5.

Probability that a poorly constructed building will be damaged by earthquake = P(P) = P(VI) * P(P | VI) =  0.5 * 0.05  = 0.025

(a) Let W be the event that a well-constructed building will be damaged during the earthquake.

Let VI, VII, VIII and IX be the event of occurrence of earthquake of intensity VI (or less), VII, VIII and IX respectively.

Then,

P(W | VI) = 0

P(W | VII) = 0.05

P(W | VIII) = 0.10

P(W | IX) = 0.20

P(VI) = 0.5,  P(VII) = 0.3, P(VIII) = 0.15, P(IX) = 0.05

By law of total probability,

Probability that a well-constructed building will be damaged by earthquake = P(W)

= P(VI) * P(W | VI) + P(VII) * P(W | VIII) + P(VI) * P(W | VIII) + P(IX) * P(W | IX)

= 0.5 * 0 + 0.3 * 0.05 + 0.15 * 0.10 + 0.05 * 0.20

=  0.04

(b)

Let P be the event that a poorly constructed building will be damaged during the earthquake.

Then,

P(P | VI) = 0.05

P(P | VII) = 0.25

P(P | VIII) = 0.50

P(P| IX) = 0.75

P(VI) = 0.5,  P(VII) = 0.3, P(VIII) = 0.15, P(IX) = 0.05

By law of total probability,

Probability that a poorly-constructed building will be damaged by earthquake = P(P)

= P(VI) * P(P | VI) + P(VII) * P(P | VIII) + P(VI) * P(P | VIII) + P(IX) * P(P | IX)

= 0.5 * 0.05 + 0.3 * 0.25 + 0.15 * 0.50 + 0.05 * 0.75

=  0.2125

Let PC and WC be the event that the building is poorly constructed and well constructed respectively. Then,

P(PC) = 0.20

P(WC) = 1 - P(PC) = 1 - 0.20 = 0.80

Let D be the event that building is damaged by the earthquake.

Then, P(D | PC) = P(P) = 0.2125

P(D | WC) = P(W) = 0.04

By law of total probability, proportion of buildings damaged by the earthquake

P(D) = P(PC) * P(D | PC) + P(WC) * P(D | WC)

= 0.2 * 0.2125 + 0.8 * 0.04

= 0.0745

(c)

Given the building is damaged, the probability that it was poorly constructed = P(PC | D)

= P(D | PC) * P(PC) / P(D)                     (By Bayes theorem)

= 0.2125 * 0.2 / 0.0745

= 0.5704698

(d)

For intensity VI (or less),

Probability that a well-constructed building will be damaged by earthquake = P(W)

= P(VI) * P(W | VI)  = 0.5 * 0 = 0

Probability that a poorly-constructed building will be damaged by earthquake = P(P)

= P(VI) * P(P | VI) =  0.5 * 0.05  = 0.025

Proportion of buildings damaged by the earthquake  = 0.20 * 0.025 + 0.80 * 0 = 0.005

For intensity VII,

Probability that a well-constructed building will be damaged by earthquake = P(W)

= P(VII) * P(W | VII)  = 0.3 * 0.05 = 0.015

Probability that a poorly-constructed building will be damaged by earthquake = P(P)

= P(VII) * P(P | VII) =  0.3 * 0.25  = 0.075

Proportion of buildings damaged by the earthquake  = 0.20 * 0.075 + 0.80 * 0.015 = 0.027

For intensity VIII,

Probability that a well-constructed building will be damaged by earthquake = P(W)

= P(VIII) * P(W | VIII)  = 0.15 * 0.10 = 0.015

Probability that a poorly-constructed building will be damaged by earthquake = P(P)

= P(VIII) * P(P | VIII) =  0.15 * 0.50 = 0.075

Proportion of buildings damaged by the earthquake  = 0.20 * 0.075 + 0.80 * 0.015 = 0.027

For intensity IX,

Probability that a well-constructed building will be damaged by earthquake = P(W)

= P(IX) * P(W | IX)  = 0.05 * 0.20 = 0.01

Probability that a poorly-constructed building will be damaged by earthquake = P(P)

= P(IX) * P(P | IX) = 0.05 * 0.75 = 0.0375

Proportion of buildings damaged by the earthquake  = 0.20 * 0.01 + 0.80 * 0.0375 = 0.032

The probability that Mike becomes the champion given that he has won the first game is 7/12.

To find the probability that Alain wins the championship given that Mike won the first game, we can repeat the same reasoning as before, but with Alain as the starting player.

P(Mike wins championship | Mike won first game) = 1 - P(Alain wins championship | Mike won first game)

This leads to:

P(Alain wins championship | Alain won first game) = 5/8

Therefore, we can conclude that:

P(Mike wins championship | Mike won first game) = 1 - P(Alain wins championship | Mike won first game) = 1 - 5/8 = 3/8 + 1/8 = 4/8 = 1/2

Answer:

The velocity v(t) of the robot at time t can be determined by taking the derivative of the position function s(t). Therefore, v(t) = 18t - 90.

To find the total distance traveled by the robot between t = 0 and t = 9, we need to calculate the definite integral of the absolute value of the velocity function from t = 0 to t = 9. This is because the absolute value of velocity gives us the speed, and integrating the speed over the given time interval gives us the total distance traveled.

Integrating the velocity function v(t) = 18t - 90 from t = 0 to t = 9, we get:

∫(0 to 9) |18t - 90| dt

To solve this integral, we split it into two parts based on the regions where the integrand changes sign:

∫(0 to 9) (90 - 18t) dt + ∫(0 to 9) (18t - 90) dt

Evaluating the integrals, we get:

[90t - 9t^2/2] from 0 to 9 + [9t^2/2 - 90t] from 0 to 9

Plugging in the limits, we have:

[90(9) - 9(9^2)/2] + [9(9^2)/2 - 90(9)] = 405

Therefore, the total distance traveled by the robot between t = 0 and t = 9 is 405 units.

In the word "sixteen," there are three e's. We are asked to find the probability that two e's are not next to each other. Let's first calculate the total number of arrangements of the letters of the word "sixteen."Total number of arrangements = 7! / (2! * 3!) = 420There are three ways in which two e's can be next to each other: ee is the first pair, ee is the second pair, and ee is the third pair. If the first two e's are next to each other, there are five choices for where to place the third e: _e_e_e_, _e_ee_, _ee_e_, _ee_e_, and _eee_. If the second two e's are next to each other, there are four choices for where to place the first e: e_e_e_, e_ee_, _ee_e, _ee_e_, and _eee_. Finally, if the last two e's are next to each other, there are five choices for where to place the first e: e_e_ee, e_e_e_, _ee_e, _ee_e_, and _eee_.So there are a total of 14 arrangements where two e's are next to each other. Therefore, the probability that two e's are not next to each other is:Probability = (total number of favorable outcomes) / (total number of possible outcomes) = (420 - 14) / 420 = 406/420 = 0.9667, or approximately 96.67%.In conclusion, the probability that two e's are not next to each other when the letters of the word "sixteen" are randomly arranged is approximately 96.67%.

To calculate the average time, we need to consider the time it takes for the bus to travel to the airport and back, as well as the time spent waiting for the bus.

If buses are dispatched every 3 minutes, and the average traveling time (a round trip) is 21 minutes, it means that passengers spend 18 minutes waiting for the bus (21 minutes - 3 minutes of traveling time).

If buses are dispatched every 0.5 minutes, the waiting time will be significantly reduced. However, the traveling time remains the same at 21 minutes for a round trip.
