The original price of the ticket was $210 and the new price is $310.

To find the percentage increase, we can use the formula:

percentage increase = (new price - old price) / old price * 100%

So, the percentage increase in the ticket price is:

percentage increase = (310 - 210) / 210 * 100% = 47.62%

Therefore, the ticket price has increased by 47.62%.

If the airline charges an additional $50 baggage fee with the new ticket price of $310, then the new price will be $360.

To find the new percentage increase, we can use the same formula:

percentage increase = (new price - old price) / old price * 100%

So, the percentage increase in the ticket price with the additional $50 baggage fee is:

percentage increase = (360 - 210) / 210 * 100% = 71.43%

Therefore, the ticket price has increased by 71.43% with the additional $50 baggage fee.

Answer:

Percent Increase= 47.619% increase, With $50 baggage fee= 71.4286% increase

Step-by-step explanation:

This expression represents the change in the function values (f (x) - f (2)) divided by the change in the x-values (x - 2), which gives us the slope of the secant line between points P and Q.

The slope of the secant line through the points P (2, f (2)) and Q (x, f(x)) can be found using the slope formula:

slope = (f (x) - f (2))/ (x - 2)

This expression represents the change in y (f(x) - f (2)) divided by the change in x (x - 2) between the two points. It gives the average rate of change of the function over that interval.

Alternatively, we could use the point-slope form of a line to find the equation of the secant line through P and Q:

y - f(2) = slope(x - 2)

where slope is given by the expression above. This equation represents a line that passes through P and Q, and it can be used to approximate the behavior of the function between those points. As x gets closer to 2, the secant line becomes a better approximation of the tangent line to the curve at that point.

The steady-state solutions of y'(t) =

[tex] y^2 - 15y + 56[/tex]

are y = 7 and y = 8, with y = 7 being a stable equilibrium point and y = 8 being an unstable equilibrium point.

The steady-state solutions of a differential equation are the values of the function that remain constant over time. To find the steady-state solutions of the given differential equation, we need to set y'(t) = 0 and solve for y.

[tex]y^2 - 15y + 56 = 0[/tex]

We can factor this quadratic equation as (y-7)(y-8) = 0, so the steady-state solutions are y = 7 and y = 8. These values are called equilibrium points or fixed points because if y(t) starts at one of these values, it will remain there as time goes on.

To understand the behavior of the system around these steady-state solutions, we can use the first derivative test. If y'(t) > 0 for y < 7 or y > 8, then y(t) is increasing and moving away from the steady-state solution. If y'(t) < 0 for 7 < y < 8, then y(t) is decreasing and moving towards the steady-state solution. Hence, y = 7 is a stable equilibrium point, and y = 8 is an unstable equilibrium point.

Answer:

Assuming that the distribution of section scores is still approximately normal with a mean of 500 and a standard deviation of 100, we can use the empirical rule (also known as the 68-95-99.7 rule) to estimate the probability that a randomly-selected student gets a section score of 700 or better.

According to the empirical rule, approximately 68% of the scores fall within one standard deviation of the mean, approximately 95% of the scores fall within two standard deviations of the mean, and approximately 99.7% of the scores fall within three standard deviations of the mean.

To estimate the probability of getting a section score of 700 or better, we need to find the proportion of scores that are more than two standard deviations above the mean.

Z-score = (X - μ) / σ = (700 - 500) / 100 = 2

From the standard normal distribution table, we find that the proportion of scores that are more than 2 standard deviations above the mean is approximately 0.0228.

Therefore, the estimated probability that a randomly-selected student gets a section score of 700 or better is about 0.0228, or 2.28%.

Yes, given the conditions provided, a, b, and c are conditionally independent given d. Conditional independence means that the probability distribution of any one of the variables is independent of the others when the conditioning variable is known.

In this case, you have the following conditional independence relationships:

1. a and b are conditionally independent given d.
2. a and c are conditionally independent given d.
3. b and c are conditionally independent given d.

To show that a, b, and c are conditionally independent given d, we need to demonstrate that the joint probability distribution of a, b, and c given d can be factored into the product of their individual conditional probability distributions.

P(a, b, c | d) = P(a | d) * P(b | d) * P(c | d)

From the given relationships, we can infer the following:

P(a, b | d) = P(a | d) * P(b | d)
P(a, c | d) = P(a | d) * P(c | d)
P(b, c | d) = P(b | d) * P(c | d)

Now, we can substitute the individual conditional probabilities from the given relationships into the expression for the joint probability distribution:

P(a, b, c | d) = P(a | d) * P(b | d) * P(c | d)

Since the joint probability distribution of a, b, and c given d can be factored into the product of their individual conditional probability distributions, a, b, and c are conditionally independent given d.

For the differential equation (2D^2 + 12D + 2)y = 0,

The characteristic equation is: 2r^2 + 12r + 2 = 0

Solving this quadratic equation using the quadratic formula, we get:

r = (-12 ± sqrt(12^2 - 4(2)(2))) / (2(2))

r = (-6 ± sqrt(32)) / 2

r = -3 ± sqrt(8)

The roots of the characteristic equation are complex conjugates, which means that the solution to the differential equation will be of the form:

y = e^(-3x) (c1 cos(sqrt(8)x) + c2 sin(sqrt(8)x))

The damping ratio is given by:

ζ = (c * n) / (2 * sqrt(a))

where c is the damping coefficient, n is the natural frequency, and a is the coefficient of the second derivative term.

In this case, c = 12, n = sqrt(8), and a = 2. Substituting these values into the above formula, we get:

ζ = (12 * sqrt(8)) / (2 * sqrt(2))

ζ = 6

Since the damping ratio ζ is greater than 1, the system is overdamped.

Therefore, the answer is (a) Overdamping.

You asked to sketch the function f(t) and find its Fourier Transform, where f(t) = 1 for 0 ≤ t < 1, and f(t) = 0 otherwise.

(i) To sketch the function f(t), follow these steps:
1. Set up a coordinate system with the horizontal axis representing time (t) and the vertical axis representing the amplitude of the function (f(t)).
2. For the time interval 0 ≤ t < 1, draw a horizontal line at f(t) = 1.
3. For any other time intervals (t < 0 or t ≥ 1), draw a horizontal line at f(t) = 0.

(ii) To find the Fourier Transform of the function f(t), use the following formula:
F(ω) = ∫[f(t) * e^(-jωt)] dt, where ω is the angular frequency and the integral is evaluated over the entire domain of the function.

Since f(t) is non-zero only in the interval 0 ≤ t < 1, we can limit the integration to that interval:
F(ω) = ∫[e^(-jωt)] dt from 0 to 1.

Now, integrate the function with respect to t:
F(ω) = [-1/jω * e^(-jωt)] evaluated from 0 to 1.

Evaluate the limits of the integral:
F(ω) = [-1/jω * e^(-jω)] - [-1/jω * e^(0)].
F(ω) = (-1/jω * e^(-jω)) + (1/jω).

So, the Fourier Transform of the function f(t) is given by:

The probability that more than 40% of 100 randomly selected physicians were sued is about 10%. Therefore, the answer is b. About 10%.

To determine the probability that more than 40% of 100 randomly selected physicians were sued, we need to find the mean and standard deviation of the sampling distribution and then use the z-score to find the probability.

1. Find the mean (µ) and standard deviation (σ) of the sampling distribution:
µ = p = 0.34 (the proportion of physicians sued for malpractice)
q = 1 - p = 0.66 (the proportion of physicians not sued for malpractice)
n = 100 (sample size)

[tex]Standard deviation (σ) = \sqrt{\frac{pq}{n} }  = \sqrt{\frac{(0.34)(0.66)}{100} } = 0.047[/tex]

Answer: The cooling of a body can be modeled using Newton's Law of Cooling, which states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. The equation for Newton's Law of Cooling is:

T(t) = T_0 + (T_s - T_0) * e^(-kt)

where T(t) is the temperature of the body at time t, T_0 is the initial temperature of the body, T_s is the temperature of the surroundings, k is the cooling constant, and e is the base of the natural logarithm.

Assuming that the temperature of the surroundings is constant at 68°F, we can use the given information to solve for t:

76.5°F = 68°F + (T_0 - 68°F) * e^(-kt)

Simplifying this equation, we get:

8.5°F = (T_0 - 68°F) * e^(-kt)

Taking the natural logarithm of both sides, we get:

ln(8.5°F / (T_0 - 68°F)) = -kt

Solving for t, we get:

t = -ln(8.5°F / (T_0 - 68°F)) / k

The cooling constant k depends on various factors such as the body's mass, the body's surface area, and the body's initial temperature. For a human body, k is typically estimated to be around 0.00087 per minute.

Assuming that the initial temperature of the body was 98.6°F (the average temperature of a living human body), we can plug in the values and solve for t:

t = -ln(8.5°F / (98.6°F - 68°F)) / 0.00087

t ≈ 16.5 hours

Therefore, it has been approximately 16.5 hours since the person died.

To determine the joint distribution for (X,Y), we need to calculate the probability of each possible outcome. There are 4 kings in the deck and 13 diamonds. We can use the formula for calculating probabilities of combinations to find the probabilities of each possible combination of kings and diamonds:

P(X = 0, Y = 0) = 36/52 * 35/51 = 0.5098

P(X = 0, Y = 1) = 36/52 * 16/51 = 0.2353

P(X = 0, Y = 2) = 36/52 * 1/51 = 0.0055

P(X = 1, Y = 0) = 16/52 * 36/51 = 0.2353

P(X = 1, Y = 1) = 16/52 * 15/51 = 0.0588

P(X = 1, Y = 2) = 16/52 * 0 = 0

P(X = 2, Y = 0) = 1/52 * 36/51 = 0.0055

P(X = 2, Y = 1) = 1/52 * 15/51 = 0.0007

P(X = 2, Y = 2) = 1/52 * 0 = 0

Therefore, the joint distribution for (X,Y) is:

To find the marginal distribution for X, we can sum the probabilities for each possible value of X:

P(X = 0) = 0.5098 + 0.2353 + 0.0055 = 0.7506

P(X = 1) = 0.2353 + 0.0588 + 0 = 0.2941

P(X = 2) = 0.0055 + 0.0007 + 0 = 0.0062

Therefore, the marginal distribution for X is:

To find the marginal distribution for Y, we can sum the probabilities for each possible value of Y:

P(Y = 0) = 0.5098 + 0.2353 + 0.0055 = 0.7506

P(Y = 1) = 0.2353 + 0.0588 + 0.0007 = 0.2948

(a) To find the probability that both David and Mary hit the target, we can use the formula for independent events: P(A and B) = P(A) x P(B).

So, P(David hits the target) = 1/5, and P(Mary hits the target) = 1/4.

Therefore, P(both hit the target) = (1/5) x (1/4) = 1/20.

(b) To find the probability that the target will be hit at least once, we can use the formula P(A or B) = P(A) + P(B) - P(A and B).

So, P(David hits the target) = 1/5, and P(Mary hits the target) = 1/4.

Therefore, P(at least one hits the target) = P(David hits the target) + P(Mary hits the target) - P(both hit the target) = (1/5) + (1/4) - (1/20) = 9/20.

So, the probability of drawing a Heart on the second card is also 13/52.

Therefore, the probability of drawing two Hearts with replacement is (13/52) x (13/52) = 169/2704, which simplifies to 0.0625 (correct to 4 decimal places).

(b) If the first card is not replaced, the probability of drawing a Heart on the first card is 13/52 (since there are 13 Hearts in a deck of 52 cards). After the first card is drawn and not replaced, there are now only 51 cards left in the deck, with 12 of them being Hearts.

So, the probability of drawing a Heart on the second card is 12/51.

Therefore, the probability of drawing two Hearts without replacement is (13/52) x (12/51) = 156/2652, which simplifies to 0.0588 (correct to 4 decimal places).

Answer: it would be 15

Step-by-step explanation:

to do this add 15 five times and you will get 75

just tell the teacher that you started at ten and then when you got to 15 it worked. orrrr...  you know there is 60 minutes in an hour and you know that it can be divided by 4 to equal 15 so you added 15 one more time and got 75

The relation "a-b a mod 4 = b mod 4" means that for any two numbers a and b, if their difference is divisible by 4, then they belong to the same equivalence class. To find the equivalence class of -, we need to find all the numbers that have the same modulus as - when divided by 4.

We can start by listing out some numbers with the same modulus as -. For example, we have {-9, -5, -1, 3, 7, ...}, since these numbers are all congruent to -1 mod 4. Similarly, we have {0, 4, 8, 12, ...} for numbers that are congruent to 0 mod 4, and {1, 5, 9, 13, ...} for numbers that are congruent to 1 mod 4.

Therefore, the equivalence class of - is {-9, -5, -1, 3, 7, ...}, which contains all the negative numbers that are congruent to -1 mod 4.

The equation that find the values of the table is y = 2x - 2.

Mrs Sanchez writes the following table of x and y values on the chalkboard. Therefore, let's find the equation that fits the values of the table.

using slope intercept form for linear equation,

y = mx + b

where

Hence,

m = -2 + 6 / 0 + 2

m = 4 / 2

m = 2

Therefore, lets' find the value of b, y intercepts using (0, -2)

Hence,

y = 2x + b

-2 = 2(0) + b

b = -2

Therefore, the equation is y = 2x -2

To begin, let's recall that synthetic division is a method used to divide a polynomial by a linear factor (i.e. a binomial of the form x-a, where a is a constant). The result of synthetic division is the quotient of the division, which is a polynomial of one degree less than the original polynomial.

In this case, we are given that x is a solution of a third-degree polynomial equation. This means that the polynomial can be factored as (x-r)(ax^2+bx+c), where r is the given solution and a, b, and c are constants that we need to determine.

To use synthetic division, we will divide the polynomial by x-r, where r is the given solution. The result of the division will give us the coefficients of the quadratic factor ax^2+bx+c.

Here's an example of how to do this using synthetic division:

Suppose we are given the polynomial P(x) = x^3 + 2x^2 - 5x - 6 and we know that x=2 is a solution.

1. Write the polynomial in descending order of powers of x:

P(x) = x^3 + 2x^2 - 5x - 6

2. Set up the synthetic division table with the given solution r=2:

2 | 1  2  -5  -6

3. Bring down the leading coefficient:

2 | 1  2  -5  -6
  ---
   1

4. Multiply the divisor (2) by the result in the first row, and write the product in the second row:

2 | 1  2  -5  -6
  ---
   1  2

5. Add the second row to the next coefficient in the first row, and write the sum in the third row:

2 | 1  2  -5  -6
  ---
   1  2 -3

6. Multiply the divisor by the result in the third row, and write the product in the fourth row:

2 | 1  2  -5  -6
  ---
   1  2 -3
       4

7. Add the fourth row to the next coefficient in the first row, and write the sum in the fifth row:

2 | 1  2  -5  -6
  ---
   1  2 -3
       4 -2

The final row gives us the coefficients of the quadratic factor: ax^2+bx+c = x^2 + 2x - 3. Therefore, the factorization of P(x) is

P(x) = (x-2)(x^2+2x-3).

To find the real solutions of the equation, we can use the quadratic formula or factor the quadratic further:

x^2 + 2x - 3 = (x+3)(x-1).

Therefore, the real solutions of the equation are x=2, x=-3, and x=1.
