1. (a) P(111 sent | 101 received) = P(101 received | 111 sent)P(111 sent) / [P(101 received | 111 sent)P(111 sent) + P(101 received | 000 sent)P(000 sent)] = 0.729

(b) P(000 sent | 000 received) = P(000 received | 000 sent)P(000 sent) / [P(000 received | 000 sent)P(000 sent) + P(000 received | 111 sent)P(111 sent)] = 0.512

2. P(Partner has 3 aces | you have 1 ace) = 3/39 = 0.077

(a) The probability of receiving 101 when 111 is sent can be calculated using Bayes' theorem. Let A be the event that 111 was sent and B be the event that 101 was received. Then, the probability that 111 was sent given that 101 was received is:

P(A|B) = P(B|A) * P(A) / P(B)

P(B|A) is the probability of receiving 101 when 111 is sent, which is the probability of one error occurring in three digits sent, given by the binomial distribution:

P(B|A) = 3C1 * (0.1)^1 * (0.9)^2 = 0.243

P(A) is the prior probability of sending 111, which is 0.6 if 1's are sent 60% of the time.

P(B) is the total probability of receiving 101, which is the sum of the probabilities of all possible ways of sending 101:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

P(B|not A) is the probability of receiving 101 when 000 is sent, which is the probability of two errors occurring in three digits sent, given by the binomial distribution:

P(B|not A) = 3C2 * (0.1)^2 * (0.9)^1 = 0.027

P(not A) is the complement of P(A), which is 0.4 if 0's are sent 40% of the time.

Therefore,

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A) = 0.243 * 0.6 + 0.027 * 0.4 = 0.1584

Finally, we have:

P(A|B) = P(B|A) * P(A) / P(B) = 0.243 * 0.6 / 0.1584 = 0.9167

So the probability that 111 was sent given that 101 was received is 0.9167, or about 91.7%.

(b) The same calculation can be done for the case of receiving 000. The probability of receiving 000 when 000 is sent is 0.729 (no errors occurring in three digits sent), while the probability of receiving 000 when 111 is sent is 0.001 (three errors occurring in three digits sent). Using Bayes' theorem as before, we get:

P(A|B) = P(B|A) * P(A) / P(B) = 0.001 * 0.6 / (0.729 * 0.6 + 0.001 * 0.4) = 0.0008

So the probability that 111 was sent given that 000 was received is 0.0008, or about 0.08%.

There are 3 remaining aces out of 51 remaining cards, so the probability that your partner has all three aces is:

P = (3/51) * (2/50) * (1/49) = 0.00000277

So the probability is very low, about 0.000277%.

Amy is considering leasing a car and has received offers from three dealers with different monthly costs, mileage allowances, and costs for additional miles.

To make a decision, Amy needs to calculate her total 36-month cost based on different mileage assumptions. She creates a payoff table showing the total cost for each dealer at different annual mileages.

In part b, Amy needs to use the expected value approach to determine which option she should choose based on the probability of driving 12,000, 15,000, or 18,000 miles per year. Amy calculates the expected value for each dealer by multiplying the probability of each annual mileage by the corresponding total cost and adding them together. The dealer with the lowest expected value is the best choice for Amy.

In part c, the probabilities for each annual mileage assumption change, so Amy needs to recalculate the expected values for each dealer. Based on the new probabilities and expected values, Amy can make a decision on which dealer to choose for her car lease.

Therefore, it will take approximately 1415.7 weeks for all of the chemical to evaporate.

To calculate the volume of a cone, we can use the formula:

\(Volume = (1/3) * π * r^2 * h\)

Given that the height (h) of the cone is 240 inches and the radius (r) is 150 inches, we can substitute these values into the formula:

\(Volume = (1/3) * 3.14 * 150^2 * 240\)

Simplifying the equation:

Volume = 3.14 * 22500 * 240

Volume ≈ 16988400 cubic inches

Now, we know that the liquid chemical evaporates at a rate of 12,000 cubic inches per week. To find out how many weeks it will take for all the chemical to evaporate, we can divide the total volume of the chemical by the evaporation rate:

Number of weeks = Volume / Evaporation rate

The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x. The cab charges $0.88 for a ride of 2 miles. And the cab charges $1.72 for a trip of 8 miles.

a. The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x

b. To find the number of miles for a cab ride that costs $0.88, we can set up the equation:

$0.88 = $0.60 + $0.14 * x

Subtracting $0.60 from both sides, we get:

$0.88 - $0.60 = $0.14 * x

$0.28 = $0.14 * x

Dividing both sides by $0.14, we find:

x = $0.28 / $0.14

x = 2 miles

Therefore, the cab charges $0.88 for a ride of 2 miles.

c. To calculate the cost of a trip of 8 miles, we can substitute x = 8 into the equation:

Cost = $0.60 + $0.14 * 8

Cost = $0.60 + $1.12

Cost = $1.72

Therefore, the cab charges $1.72 for a trip of 8 miles.

Answer:

7/18

Step-by-step explanation:

First we need to find what values of sum we can have.

The minimum value for a cube is 1, so the minimum value for the sum is 2.

The maximum value for a cube is 6, so the maximum value for the sum is 12.

Now, we find the multiples of 6 and the multiples of 4 between 2 and 12:

4, 6, 8, 12.

To have a sum of 4, we can have the pairs:

(1,3), (2,2), (3,1)

To have a sum of 6, we can have the pairs:

(1,5), (2,4), (3,3), (4,2), (5,1)

To have a sum of 8, we can have the pairs:

(2,6), (3,5), (4,4), (5,3), (6,2)

To have a sum of 12, we can have the pairs:

(6,6)

So we have 14 pairs among the 36 (6 possibilities of each cube, so 6*6=36) total possibilities of pairs, so the probability is P = 14/36 = 7/18

The probability that the outcome of the roll is a sum that is a multiple of 6 or a sum that is a multiple of 4 is,      \(P(E)=\frac{14}{36}=\frac{7}{18}\)

The probability of any event is computed as divide number of favourable outcomes by total number of outcomes.

The sum that is a multiple of 6 or a sum that is a multiple of 4  are   4, 6, 8 and 12.

For sum of 4, we can have the pairs = (1,3), (2,2), (3,1)

For sum of 6, we can have the pairs: = (1,5), (2,4), (3,3), (4,2), (5,1)

For sum of 8, we can have the pairs = (2,6), (3,5), (4,4), (5,3), (6,2)

For sum of 12, we can have the pairs = (6,6)

Total number of favourable outcomes = 14

When two distinct number cubes are rolled. then,

Total number of outcomes  \(=6^{2}=36\)

The probability that the outcome of the roll is a sum that is a multiple of 6 or a sum that is a multiple of 4,

After answering the provided question, we can conclude that As a result, equation the cost of 2 pounds of candy is $7.00.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "\(2x + 3 = 9"\) asserts that the statement "\(2x + 3\)" equals the value "9". The goal of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complex, regular or nonlinear, and include one or more factors. In the equation "\(x2 + 2x - 3 = 0\)," for example, the variable x is raised to the second power. Lines are used in many different areas of mathematics, such as algebra, calculus, and geometry.

Claim: To calculate the cost of 2 pounds of candy, multiply the cost per pound of candy by 2.

According to the data provided, the cost per pound of candy is $3.50.

Reasoning: In order to determine the cost of 2 pounds of candy, we must first determine the total cost of 2 pounds of candy. Because the price per pound of candy is $3.50, we can calculate the total cost by multiplying the price per pound by the number of pounds. In this case, we want to know how much it costs for two pounds, so we multiply $3.50 by two to get:

2 pounds of candy = $3.50 per pound x 2 pounds = $7.00

As a result, the cost of 2 pounds of candy is $7.00.

Answer:

\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)

Step-by-step explanation:

Swap f(x) and x position of the function, thus:

\(\displaystyle{x=7f(x)+3}\)

Then solve for f(x), subtract 3 both sides and then divide both by 7:

\(\displaystyle{x-3=7f(x)}\\\\\displaystyle{\dfrac{x}{7}-\dfrac{3}{7}=f(x)}\)

Since the function has been inverted, therefore:

\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)

And we can prove the answer by substituting x = 1 in f(x) which results in:

\(\displaystyle{f(1)=7(1)+3 = 10}\)

The output is 10, now invert the process by substituting x = 10 in \(f^{-1}(x)\):

\(\displaystyle{f^{-1}(10)=\dfrac{10}{7}-\dfrac{3}{7}}\\\\\displaystyle{f^{-1}(10)=\dfrac{7}{7}=1}\)

The input is 1. Hence, the solution is true.

Answer:

x = -0.5

Step-by-step explanation:

Here we have the sentence:

"3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtracted by 6"

The first part:

"3 to the power 2x+3 is subtracted by 9..."

This can be written as:

\(3^{2x + 3} - 9\)

"... is equal to 2 times 9 to the power x+1 and is subtracted by 6"

\(3^{2x + 3} - 9 = 2*9^{x + 1} - 6\)

Let's solve this for x.

First, we can add 9 in both sides:

\(3^{2x + 3} = 2*9^{x + 1} - 6 + 9 = 2*9^{x + 1} + 3\)

We also know the relations:

\(a^n*a^b = a^{n + b}\)

and

\((a^n)^m = a^{n*m}\)

We can write the left part as:

\(3^{2x + 3} = 3^{2x}*3^3 = (3^2)^x*3^3 = 9^x*27\)

And the right side as:

\(2*9^{x + 1} + 3 = 2*9^x*9 + 3 = 18*9^x + 3\)

Then the equation becomes:

\(27*9^x = 18*9^x + 3\)

Now let's move both terms with 9^x to the left side:

\(27*9^x - 18*9^x = 3\\\)

\((27 - 18)*9^x = 3\)

\(9*9^x = 3\)

\(9^x = 3/9 = 1/3\)

Now remember that:

Ln(a^b) = b*Ln(a)

Then if we apply the Ln( ) function to both sides, we get:

\(Ln(9^x) = Ln(1/3)\)

\(x*Ln(9) = Ln(1/3)\)

\(x = \frac{Ln(1/3)}{Ln(9)} = -0.5\)

For a Poisson process with rate λ, the interarrival times between events are exponentially distributed with parameter μ = 1/λ. So, the time between the (n-1)-th and n-th event, denoted as Tn, follows an exponential distribution with parameter μ = 1/3 minutes.

Since Sn is the sum of the first n interarrival times, we have:

Sn = T1 + T2 + ... + Tn

The sum of n exponential random variables with parameter μ is a gamma random variable with shape parameter n and scale parameter μ. Therefore, Sn follows a gamma distribution with shape parameter n and scale parameter μ.

In this case, n = 10 and μ = 1/3. So, E[S10] can be calculated as:

E[S10] = n * μ = 10 * (1/3)

= 10/3 minutes.

Therefore, E[S10] = 10/3 minutes.

b. E[S4|N(1) = 3]:

Given that N(1) = 3, we know that there are 3 events in the first minute. Therefore, the time of the 4th event, S4, will be the sum of the first 3 interarrival times plus the time between the 3rd and 4th event.

Using the same reasoning as in part a, we know that the sum of the first 3 interarrival times follows a gamma distribution with shape parameter 3 and scale parameter 1/3. The time between the 3rd and 4th event, denoted as T4, follows an exponential distribution with parameter 1/3.

So, S4 = T1 + T2 + T3 + T4.

Since T1, T2, T3 are independent of T4, we can calculate E[S4|N(1) = 3] as:

E[S4|N(1) = 3] = E[T1 + T2 + T3 + T4]

= E[T1 + T2 + T3] + E[T4]

= (3/3) + (1/3)

= 4/3 minutes.

Therefore, E[S4|N(1) = 3] = 4/3 minutes.

c. Var(S10):

The variance of Sn, Var(Sn), for a Poisson process with rate λ, is given by:

Var(Sn) = n * σ^2,

where σ^2 is the variance of the interarrival times.

In this case, n = 10 and the interarrival times are exponentially distributed with parameter μ = 1/3. The variance of an exponential distribution is \(\mu^2\)So, \(\sigma^2 = \left(\frac{1}{3}\right)^2\)

= 1/9.

Substituting the values into the formula, we have:

Var(S10) = 10 * (1/9)

= 10/9.

Therefore, Var(S10) = 10/9.

d. E[N(4) − N(2)|N(1) = 3]:

Given that N(1) = 3, we know that there are 3 events in the first minute. Therefore, at time t = 2 minutes, there will be 3 - 1 = 2 events that have already occurred.

Now, we need to find the expected value of the difference in the number of events between time t = 4 minutes and t = 2 minutes, given that there were 3 events at t = 1 minute.

Since the number of events in a Poisson process follows a Poisson distribution with rate λt, where t is
