In how many ways can you give three baseball tickets, three soccer tickets, and three opera tickets, all general admission, to nine friends?

Answers

Answer 1

There are 302,400 number of ways to give three baseball tickets, three soccer tickets, and three opera tickets to nine friends.

To determine the number of ways to give three baseball tickets, three soccer tickets, and three opera tickets to nine friends, you can follow these steps:

1. First, we will distribute the three baseball tickets among the nine friends. Since there are nine friends, there are 9 ways to choose the first friend, 8 ways to choose the second friend, and 7 ways to choose the third friend. So there are 9 x 8 x 7 ways to distribute the baseball tickets.

2. Next, we will distribute the three soccer tickets among the remaining six friends who didn't get a baseball ticket. There are 6 ways to choose the first friend, 5 ways to choose the second friend, and 4 ways to choose the third friend. So there are 6 x 5 x 4 ways to distribute the soccer tickets.

3. Finally, we will distribute the three opera tickets among the remaining three friends who didn't get a baseball or soccer ticket. There are 3 ways to choose the first friend, 2 ways to choose the second friend, and 1 way to choose the third friend. So there are 3 x 2 x 1 ways to distribute the opera tickets.

4. Now, we multiply the number of ways to distribute each type of ticket to find the total number of ways to distribute all the tickets: (9 x 8 x 7) x (6 x 5 x 4) x (3 x 2 x 1) = 302,400.

So, there are 302,400 ways to give three baseball tickets, three soccer tickets, and three opera tickets to nine friends.

Answer 2

The total number of ways to give the tickets is 9!/3!3!3! = 1680.

The total number of ways to give nine tickets to nine friends is 9! (9 factorial) which equals 362,880. However, since we have three types of tickets and each type has three tickets, we need to divide this number by the number of ways to arrange the three tickets of each type, which is 3! (3 factorial) for each type.

To solve this problem, we need to use the permutation formula which is n!/(n-r)!, where n is the total number of objects and r is the number of objects we need to choose. In this case, we have nine tickets and nine friends, so n = r = 9. Therefore, the total number of ways to give the tickets is 9!/9! = 1.

However, since we have three types of tickets and each type has three tickets, we need to divide this number by the number of ways to arrange the three tickets of each type, which is 3! for each type.

This is because we don't care which baseball ticket or soccer ticket or opera ticket each friend gets, we only care about how many of each type of ticket they get. Therefore, we need to divide the total number of ways by 3!3!3!. This gives us 1680, which is the final answer.

calculate the area of the circle =6sin() as an integral in polar coordinates. be careful to choose the correct limits of integration.

Answers

The area of the circle r = 6sin(θ) in polar coordinates is 9π square units.

How to calculate the area of circle?

To calculate the area of the circle r = 6sin(θ) in polar coordinates, we can integrate the expression for the area of an infinitesimal sector of the circle, which is:

dA = (1/2) [tex]r^2[/tex] dθ

Integrating this expression over the limits of θ from 0 to π, we obtain:

A = ∫₀[tex]^\pi[/tex] (1/2) [tex]r^2[/tex] dθ

Substituting r = 6sin(θ), we get:

A = ∫₀[tex]^\pi[/tex] (1/2) (6sin(θ)[tex])^2[/tex]dθ

Simplifying, we have:

A = 18 ∫₀[tex]^\pi[/tex] [tex]sin^2[/tex] (θ) dθ

Using the identity [tex]sin^2[/tex](θ) = (1/2) - (1/2)cos(2θ), we can rewrite the integral as:

A = 18 ∫₀[tex]^\pi[/tex] [(1/2) - (1/2)cos(2θ)] dθ

Evaluating this integral, we get:

A = 18 [(θ/2) - (1/4)sin(2θ)] from 0 to π

Substituting the limits of integration, we get:

A = 18 [(π/2) - (1/4)sin(2π)] - 18 [(0/2) - (1/4)sin(2(0))]

Simplifying, we have:

A = 18 [(π/2) - 0] - 18 [(0) - 0]

A = 18 (π/2)

Therefore, the area of the circle r = 6sin(θ) in polar coordinates is 9π square units.

bob makes a 95% confidence interval with a random sample of 100 and his margin of error is plus or minus 18. in order to cut the margin of error in half next time, what should bob's sample size be?

Answers

If he wants to maintain the same level of confidence (95%), his new sample size should be 400. This means that his margin of error will be plus or minus 9. It's important to note that the margin of error is affected by both the sample size and the level of confidence.

To cut the margin of error in half, Bob should increase his sample size. The margin of error is related to the sample size by the formula:

Margin of Error = Z * (Standard Deviation / sqrt(Sample Size))

Here, Z represents the Z-score associated with the desired confidence level (95% in this case). To halve the margin of error, the sample size should be increased by a factor of 4. This is because when you divide the margin of error by 2, you need to compensate by multiplying the denominator by 4 to maintain equality.

So, if Bob's current sample size is 100, he should increase it to:

New Sample Size = 100 * 4 = 400

By using a sample size of 400, Bob can cut his margin of error in half while maintaining the same 95% confidence level.

A fair coin is tossed 27 times. In how many outcomes do at most 25 heads occur? a) 351 b) 379 c) 134,217,700 d) 134,217,349e) 28

Answers

If A fair coin is tossed 27 times, in 134,217,349 outcomes do at most 25 heads occur. So, correct option is D.

To solve this problem, we need to use the binomial distribution, which gives us the probability of getting a certain number of successes (heads in this case) in a fixed number of independent trials (coin tosses).

Let p be the probability of getting a head in one toss, which is 1/2 for a fair coin. Then, the probability of getting k heads in n tosses is given by the binomial probability formula:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items out of n without regard to order, and is given by:

(n choose k) = n! / (k! * (n-k)!)

Now, to find the number of outcomes where at most 25 heads occur, we need to add up the probabilities for k = 0, 1, 2, ..., 25:

P(at most 25 heads) = P(0) + P(1) + P(2) + ... + P(25)

We can calculate each of these probabilities using the binomial probability formula, and then add them up to get the total probability.

Alternatively, we can use the cumulative distribution function (CDF) of the binomial distribution, which gives us the probability of getting k or fewer heads in n tosses.

Then, we can subtract the probability of getting exactly 26 or 27 heads from this total to get the probability of getting at most 25 heads. The formula for the binomial CDF is:

F(k) = sum(i=0 to k) [(n choose i) * p^i * (1-p)^(n-i)]

Using a calculator, we can find that the number of outcomes where at most 25 heads occur is approximately 134,217,349, which is option (d).

all humans are 2 legged, chirpy is 2 legged, therefore chirpy is a human

Answers

The given argument "all humans are 2 legged, chirpy is 2 legged, therefore chirpy is a human" is not valid because there could be other creatures, apart from humans, that are also 2 legged.

This is a logical fallacy where one assumes that if a condition is true, then the consequent must also be true. However, this does not necessarily hold true because there could be multiple reasons for the consequent to be true.

In this case, the argument assumes that because all humans are 2 legged and chirpy is 2 legged, chirpy must be a human. However, this argument overlooks the fact that there could be other creatures, apart from humans, that are also 2 legged.

For instance, birds, kangaroos, and even some primates are 2 legged but are not human. Hence, the argument fails to establish a conclusive relationship between the premises and the conclusion.

To prove that an argument is valid, we must ensure that the conclusion necessarily follows from the premises. In this case, the argument does not meet this criterion. Therefore, it is not valid.

consider the following ar(1) sequence: yt=0.8yt-1+et for t = 1, 2, ... where {et: t = 1, 2,...} is i.i.d. sequence with a mean of zero and variance of σ2e.

Answers

AR(1) model has a stationary, Zero-mean process with exponentially decaying autocorrelation and a variance that depends on the variance of the noise term. The variance of the model is [tex]\sigma ^2e / 0.36.[/tex]

The AR(1) model given is:

yt = 0.8yt-1 + et

where {et: t = 1, 2, ...} is an i.i.d. sequence with a mean of zero and variance of σ^2e.

To better understand this model, we can look at its properties:

Stationarity: For this AR(1) model to be stationary, we require that the absolute value of the AR(1) coefficient, 0.8, be less than 1. Since 0.8 < 1, the model is stationary.

γk = Cov(yt, yt-k)

Using the formula for the covariance of an AR(1) model, we have[tex]γk = (0.8)^k * σ^2e / (1 - (0.8)^2)[/tex]

Thus, the ACF for this model decays exponentially with lag k, indicating that past values of y are highly correlated with each other.

Mean: Since the model is stationary, we can calculate its mean by setting yt = yt-1 = ... = y0 = μ, and solving for μ:

μ = 0.8μ

Solving for μ, we get μ = 0, indicating that the mean of the model is zero.

Variance: We can calculate the variance of the model by using the formula for the variance of an AR(1) model:

[tex]Var(yt) = \sigma ^2e / (1 - (0.8)^2)[/tex]

Thus, the variance of the model is σ^2e / 0.36.

Overall, this AR(1) model has a stationary, zero-mean process with exponentially decaying autocorrelation and a variance that depends on the variance of the noise term.

the residents of a city voted on whether to raise property taxes. the ratio of yes votes to no votes was 5 to 3. if there were 2949 no votes, what was the total number of votes?

Answers

The total number of votes cast in the city was 7864.

Given that there were 2949 no votes, which corresponds to 3 parts of the ratio.

Assume that the total number of votes as x. According to the given information, the ratio of yes votes to no votes is 5 to 3. This means that for every 5 yes votes, there are 3 no votes.

Set up the equation as given:

3 parts = 2949 votes

1 part = 2949 votes / 3

1 part = 983 votes

Now, since the ratio of yes votes to no votes is 5 to 3,  a total of 5 + 3 = 8 parts.

Total number of votes = 8 parts × 983 votes per part

Total number of votes = 7864 votes

Thus, the characteristic equation of the differential equation is given by [tex]λ^2 + 361 = 0[/tex]. Solving the characteristic equation, we get two complex roots [tex]λ = ±19i.[/tex]

Therefore, the general solution of the differential equation is given by I(t) = [tex]c1cos(19t) + c2sin(19t)[/tex], where c1 and c2 are constants determined by the initial conditions. Differentiating the general solution with respect to t, we get [tex]I'(t) = -19c1sin(19t) + 19c2cos(19t).[/tex]

Answers

P(X<=16) = 1 - P(X>16)

= 1 - (P(X=17) + P(X=18) + ... + P(X=20))

= 0.998

This is a binomial distribution problem, where we have a fixed number of trials (20 patients), each trial can have one of two outcomes (recover or not recover), and the Probability of success (recovering) is 0.8. We can use the binomial probability formula to solve each part of the problem:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where:

P(X=k) is the probability of getting k successes

n is the total number of trials

k is the number of successes we want to find the probability for

p is the probability of success for each trial

(1-p) is the probability of failure for each trial

(n choose k) is the binomial coefficient, which is the number of ways to choose k successes out of n trials.

Using this formula, we can solve each part of the problem:

Probability that exactly 14 recover:

P(X=14) = (20 choose 14) * (0.8)^14 * (0.2)^6

= 0.214

Probability that at least 14 recover:

P(X>=14) = P(X=14) + P(X=15) + P(X=16) + ... + P(X=20)

To calculate this, we can use a binomial cumulative distribution table or calculator, or we can use the complement rule:

P(X>=14) = 1 - P(X<14)

= 1 - (P(X=0) + P(X=1) + ... + P(X=13))

= 1 - ((20 choose 0) * (0.8)^0 * (0.2)^20 + (20 choose 1) * (0.8)^1 * (0.2)^19 + ... + (20 choose 13) * (0.8)^13 * (0.2)^7)

= 0.993

Probability that at least 14 but not more than 18 recover:

P(14<=X<=18) = P(X=14) + P(X=15) + ... + P(X=18)

To calculate this, we can use a binomial cumulative distribution table or calculator, or we can subtract the probabilities of getting fewer than 14 and more than 18:

P(14<=X<=18) = P(X>=14) - P(X>=19)

= 0.993 - (P(X=19) + P(X=20))

= 0.007

Probability that at most 16 recover:

P(X<=16) = P(X=0) + P(X=1) + ... + P(X=16)

To calculate this, we can use a binomial cumulative distribution table or calculator, or we can use the complement rule:

The particular solution is y = (5/2)t + 9/(5t+6) and this equation is separable since we can write it as:
dy/dt = 5/(5t+6)

Multiplying both sides by (5t+6) gives:
(5t+6)dy/dt = 5

Integrating both sides with respect to t gives:
∫(5t+6)dy = ∫5 dt

Simplifying the integrals gives:

a pool holds 18000gallons of water. a pump drains the pool at a rate of gallons per minute. which shows how many minutes, , it will take to drain the pool so that it holds less than gallons of water?

Answers

It will take (18,000 - Y) ÷ X minutes to drain the pool so that it holds less than Y gallons of water .

To solve this problem, we need to use a simple formula:

Time = Amount of Water ÷ Rate of Drain

We know that the amount of water in the pool is 18,000 gallons. We also know that the pump drains the pool at a certain rate, which is not given in the question. Therefore, we need to find out the rate of drain first.

Let's say that the pump drains the pool at a rate of X gallons per minute. This means that in one minute, X gallons of water will be drained from the pool. Therefore, the amount of water left in the pool after one minute of draining will be:

18,000 - X

Similarly, after two minutes of draining, the amount of water left in the pool will be:

18,000 - 2X

We can continue this pattern to find the amount of water left in the pool after any given number of minutes of draining.

Now, we need to find out how many minutes it will take to drain the pool so that it holds less than Y gallons of water. Let's say that Y is the given amount of water.

We can set up an equation using the formula above:

Time = Amount of Water ÷ Rate of Drain

Time = (18,000 - Y) ÷ X

Simplifying this equation, we get:

Time = 18,000 ÷ X - Y ÷ X

Time = (18,000 - Y) ÷ X

Therefore, it will take (18,000 - Y) ÷ X minutes to drain the pool so that it holds less than Y gallons of water.

cos(R) = ([tex]4.3^2 + 6.5^2 - 8.9^2[/tex])/(2 * 4.3 * 6.5)

cos(R) = - 0.312

R = arc cos(- 0.312)

R = 107.5 degrees (adjusted to the closest tenth)

Accordingly, the proportion of point ZR is basically 180 - (90 + R) = 82.5 degrees (adjusted to the closest tenth).Utilizing the Law of Cosines, we can see that the biggest point in the triangle is at vertex S, which estimates roughly 119.5 degrees.

Point R is inverse the side of length 6.5 inches and point Z is inverse the side of length 4.3 inches. The point ZR is the contrast between 180 degrees and the amount of points Z and R. This computation provides us with a proportion of roughly 82.5 degrees.

The expression that can be written in the form (ax + b)(ax - b), where a and b are integers can be represented as follows:

Therefore,

The expression should be able to be express in the form as follows:

(ax + b)(ax - b)

x² - 9 = (x - 3)(x + 3)

Therefore,

(x - 3)(x + 3) = x² + 3x - 3x - 9

x² + 3x - 3x - 9  = x² - 9

Therefore,

(x - 3)(x + 3) = x² - 9

9x² - 4 = (3x + 2)(3x - 2)

(3x + 2)(3x - 2) = 9x² - 6x + 6x - 4

State whether the function is a polynomial function or not. If it is, give its degree. It is not, tell why not. f(x)=8-x^3/8

Answers

The function f(x) = 8 - x^3/8 is a polynomial function of degree 3.

To see why, note that a polynomial function is a function of the form f(x) = a_n x^n + a_{n-1} x^{n-1} + ... + a_1 x + a_0, where n is a non-negative integer and a_n, a_{n-1}, ..., a_1, a_0 are constants (coefficients). In this case, we have:

f(x) = 8 - x^3/8

= 8 - (1/8)x^3

= 0x^4 + 0x^3 + (-1/8)x^2 + 0x + 8

Thus, we can write f(x) as a polynomial function with degree 3, since the highest power of x that appears is x^3.

solve the integral 0 pi/;2 2 5 r^3sin(ttheta) with numerical integration

Answers

The integral with numerical integration is, 19.246.

To solve the integral numerically, we can use the trapezoidal rule or Simpson's rule. Here, we will use Simpson's rule. The formula for Simpson's rule for integrating a function f(x) over an interval [a,b] is:

[tex]\int_a^b f(x) dx[/tex] = (b-a)/6 * [f(a) + 4f((a+b)/2) + f(b)]

In this case, our integral is:

[tex]\int_0^{\pi/2} \int_2^5 r^3 sin(\theta) dr d\theta[/tex]

We can rewrite the integrand as a function of r and θ:

f(r,θ) = r³ sin(θ)

Using Simpson's rule, we can approximate the integral as:

[tex]\int_0^{\pi/2} \int_2^5 r^3 sin(\theta) dr d\theta[/tex]≈ (π/4)/3 * [(2³ sin(0) + 2³ sin(5))/2 + 4(3³ sin(π/4) + 3³ sin(3π/4))/2 + 2(5³ sin(π/2) + 5³ sin(π/2))/2]

Simplifying this expression, we get:

[tex]\int_0^{\pi/2} \int_2^5 r^3 sin(\theta) dr d\theta[/tex] ≈ 19.246

Therefore, the final answer is approximately 19.246.

a boat leaves the marina and sails 3 miles north, then 2 miles northeast. how far from the marina is the boat, and in what direction must it sail to head directly back to the marina?

Answers

The boat is approximately 4.12 miles from the marina and its direction is northeast. To head directly back to the marina, the boat must sail southwest.

To determine the boat's distance from the marina and the direction to head back, we'll use the Pythagorean theorem and some trigonometry.

After sailing 3 miles north and 2 miles northeast, the boat's total displacement is a right-angled triangle with legs of 3 miles (north) and 2√2 miles (east). The hypotenuse represents the straight-line distance back to the marina.

Using the Pythagorean theorem, distance^2 = (3^2) + (2√2)^2 = 9 + 8 = 17. So, the distance is √17 ≈ 4.12 miles.

To find the direction, we'll calculate the angle formed by the northward displacement and the straight-line path back to the marina. Using tangent, tan(angle) = (2√2)/3. The angle is arctan(2√2/3) ≈ 49.1 degrees.

So, the boat is approximately 4.12 miles from the marina and must sail 49.1 degrees west of south to head directly back to the marina.
