The television show Game of Thrones has a 24 share, meaning that while it is being broadcast, 24% of the TV sets in use are tuned to Game of Thrones. In a special focus group consisting of 200 randomly selected households (each with 1 TV set), Find the probability that at least 50 (out of the 200) are tuned in to Game of Thrones. (5 points)

The probability that none of the households are tuned to Ghost Whistler is approximately 0.0007219.

The probability that at least one household is tuned to Ghost Whistler is approximately 0.9992781.

The probability that at most one household is tuned to Ghost Whistler is approximately 0.0007476.

Since the probability of at most one household tuning in is very low, it suggests that the 32% share value may be incorrect, as it is unusual for such a low occurrence if the share value is accurate.

To find the probability that none of the households are tuned to Ghost Whistler, we can use the concept of binomial probability. Since each household has a 32% chance of tuning in, the probability of one household not tuning in is 1 - 0.32 = 0.68.

P(none) = (0.68)^15 ≈ 0.0007219

To find the probability that at least one household is tuned to Ghost Whistler, we can subtract the probability of none of the households tuning in from 1.

P(at least one) = 1 - P(none) ≈ 1 - 0.0007219 ≈ 0.9992781

To find the probability that at most one household is tuned to Ghost Whistler, we sum the probabilities of zero and one households tuning in.

P(at most one) = P(none) + P(one) ≈ 0.0007219 + (15 * 0.32 * 0.68^14) ≈ 0.0007476

Since the probability of at most one household tuning in is very low (0.07476%), it suggests that the 32% share value may be incorrect. It is unusual for such a low occurrence of households tuning in if the share value is accurate.

The correct question should be :

The television show Ghost Whistler has been successful for many years. That show recently had a share of 32, which means that among the TV sets in use, 32% were tuned to Ghost Whistler. An advertiser wants to verify that 32% share value by conducting its own survey, and a pilot survey begins with 15 households have TV sets in use at the time of a Ghost Whistler broadcast. Find the probability that none of the households are tuned to Ghost Whistler. P(none) - Find the probability that at least one household is tuned to Ghost Whistler. P(at least one) = Find the probability that at most one household is tuned to Ghost Whistler. Plat most one) = If at most one household is tuned to Ghost Whistler, does it appear that the 32% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Ghost Whistler unusual?) O no, it is not wrong O yes, it is wrong

The total number of TV sets sold is 20 + 25 = 45.

Let the number of 42′′ TV sold be x and the number of 55′′ TV sold be x + 5.

The cost of 42′′ TV is $400.The cost of 55′′ TV is $730.

So, the total amount collected = $26,250.

Therefore, by using the above-mentioned information we can write the equation:400x + 730(x + 5) = 26,250

Simplifying this equation, we get:

1130x + 3650 = 26,2501130x = 22,600x = 20

Thus, the number of 42′′ TV sold is 20 and the number of 55′′ TV sold is 25 (since x + 5 = 20 + 5 = 25).

The solution to the equation is x = 11. To solve the equation 6 + 2x = 4(x + 2) - 3(x - 3), we can simplify the equation by expanding and combining like terms:

6 + 2x = 4x + 8 - 3x + 9

Next, we can simplify further by combining the terms with x on one side:

6 + 2x = x + 17

To isolate the variable x, we can subtract x from both sides of the equation:

6 + 2x - x = x + 17 - x

Simplifying the left side:

6 + x = 17

Now, we can subtract 6 from both sides:

6 + x - 6 = 17 - 6

18 liters of the 10% alcohol solution should be mixed with the 12 liters of the 20% alcohol solution to obtain a 14% alcohol solution by concentration calculations.

To obtain a 14% alcohol solution, 6 liters of a 10% alcohol solution should be mixed with 12 liters of a 20% alcohol solution.

Let's break down the problem step by step. We have two solutions: a 10% alcohol solution and a 20% alcohol solution. Our goal is to find the amount of the 10% alcohol solution needed to mix with the 20% alcohol solution to obtain a 14% alcohol solution.

To solve this, we can set up an equation based on the concept of the concentration of alcohol in a solution. The equation can be written as follows:

0.10x + 0.20(12) = 0.14(x + 12)

In this equation, 'x' represents the volume (in liters) of the 10% alcohol solution that needs to be added to the 20% alcohol solution. We multiply the concentration of alcohol (as a decimal) by the volume of each solution and set it equal to the concentration of alcohol in the resulting mixture.

Now, we can solve the equation to find the value of 'x':

0.10x + 2.4 = 0.14x + 1.68

0.14x - 0.10x = 2.4 - 1.68

0.04x = 0.72

x = 0.72 / 0.04

x = 18

Therefore, 18 liters of the 10% alcohol solution should be mixed with the 12 liters of the 20% alcohol solution to obtain a 14% alcohol solution by concentration calculations.

B(n,π) is a binomial random variable. When the probability of success is near 0 or 1, it is easier to get a precise estimate of π than when it is near 2.

In order to see why this is true, we need to understand how the variance of the estimate of π changes when the value of π changes.

The variance of the estimate of π is equal to π(1-π)/n. When π is near 0 or 1, the variance of the estimate of π is small. When π is near 0 or 1, the variance of the estimate of π is large.

This means that it is easier to get a precise estimate of π when it is near 0 or 1 than when it is near 2.

A binomial random variable is defined by two parameters: n, the number of trials, and π, the probability of success on each trial.

The value of π can range from 0 to 1. When π is near 0 or 1, it is easier to get a precise estimate of π than when it is near 2. To understand why this is true, we need to look at the variance of the estimate of π.

The variance of the estimate of π is equal to π(1-π)/n. This means that the variance of the estimate of π depends on the value of π and the number of trials.

When π is near 0 or 1, the variance of the estimate of π is small. This is because the product of π and (1-π) is small, which means that the variance is small.

When π is near 2, the variance of the estimate of π is large. This is because the product of π and (1-π) is large, which means that the variance is large.

When the variance of the estimate of π is small, it is easier to get a precise estimate of π. This is because the estimate is less likely to be far from the true value of π.

When the variance of the estimate of π is large, it is harder to get a precise estimate of π. This is because the estimate is more likely to be far from the true value of π.

In conclusion, it is easier to get a precise estimate of π when it is near 0 or 1 than when it is near 2. This is because the variance of the estimate of π is smaller when π is near 0 or 1, which makes it easier to get a precise estimate of π. When π is near 2, the variance of the estimate of π is larger, which makes it harder to get a precise estimate of π.

Here, we have to define an exponential function, f(x), which passes through the points (0,216) and (3,27). The exponential function in the form of a*b^(x) is given below:f (x) = a * b^(x)

To find the value of a and b, we need to use the points (0,216) and (3,27).

When x = 0, we have f(0) = 216.

So,216 = a * b^(0)216 = a * 1a = 216

To calculate the probability, we need to find the intersection of two events: owning a house and taking a bank loan. Given that 66% of Abu Dhabi residents own a house and 4.1% of homeowners took bank loans, we can find the probability.

Let's denote:

A = Event of owning a house

B = Event of taking a bank loan

The probability of owning a house is P(A) = 0.66 (66%).

The probability of taking a bank loan among homeowners is P(B|A) = 0.041 (4.1%).

To find the probability that a randomly selected Abu Dhabi resident owns a house and took a bank loan, we calculate the intersection probability using the formula:

P(A ∩ B) = P(A) * P(B|A)

P(A ∩ B) = 0.66 * 0.041

P(A ∩ B) = 0.02706

Given:

Probability function, f(x) = {1 - 0.5x}, for 0 < x < 2

To Find:

Mean and Variance of Random variable X

Formulae:

Mean: E(X) = ∑(x*f(x))

Variance: Var(X) = E(X^2) - (E(X))^2

Calculations:

The possible values of X are: 0, 1, 2.

Let's calculate E(X) using the formula:

Mean E(X) = ∑(x*f(x))

So,

E(X) = ∑(x*f(x))

E(X) = 0*(1-0.5*0) + 1*(1-0.5*1) + 2*(1-0.5*2)

E(X) = 0 + 0.5 + 1 = 1.5

Hence, the mean of random variable X is 1.5.

Let's calculate E(X^2) using the formula:

E(X^2) = ∑(x^2*f(x))

So,

E(X^2) = ∑(x^2*f(x))

E(X^2) = 0^2*(1-0.5*0) + 1^2*(1-0.5*1) + 2^2*(1-0.5*2)

E(X^2) = 0 + 0.5 + 2 = 2.5

Hence, E(X^2) = 2.5

Using the formula,

Var(X) = E(X^2) - (E(X))^2

Var(X) = 2.5 - (1.5)^2

Var(X) = 2.5 - 2.25

Var(X) = 0.25

Difference quotient = f(a + h) - f(a)/h = 4(2a + h)

f(x) = 4x² + 9 is a function where x is a real number.

To find f(a), we can replace x with a in the function to get: f(a) = 4a² + 9. Similarly, to find f(a + h), we can replace x with (a + h) in the function to get: f(a + h) = 4(a + h)² + 9

Let's differentiate the function [tex]\(\phi(x, y) = e^{x^2 - y^2} \cos(2xy)\) with respect to \(x\):\[\frac{\partial \phi}{\partial x} = \frac{\partial}{\partial x} \left(e^{x^2 - y^2} \cos(2xy)\right) = \frac{\partial}{\partial x}\left(e^{x^2 - y^2}\right) \cos(2xy) - e^{x^2 - y^2} \sin(2xy) \cdot 2y\]\[\Rightarrow \frac{\partial \phi}{\partial x} = 2xe^{x^2 - y^2} \cos(2xy) - 2ye^{x^2 - y^2} \sin(2xy)\][/tex]

[tex]Similarly, differentiate \(\phi(x, y)\) with respect to \(y\):\[\frac{\partial \phi}{\partial y} = \frac{\partial}{\partial y} \left(e^{x^2 - y^2} \cos(2xy)\right) = -e^{x^2 - y^2} \sin(2xy) \cdot 2x - \frac{\partial}{\partial y}\left(e^{x^2 - y^2}\right) \cos(2xy)\]\[\Rightarrow \frac{\partial \phi}{\partial y} = -2xe^{x^2 - y^2} \sin(2xy) - 2ye^{x^2 - y^2} \cos(2xy)\][/tex]

Now, substitute these derivatives of \(\phi(x, y)\) in the first Cauchy-Riemann equation:

[tex]\[\frac{\partial \phi}{\partial x} = \frac{\partial \psi}{\partial y}\]\[2xe^{x^2 - y^2} \cos(2xy) - 2ye^{x^2 - y^2} \sin(2xy) = \frac{\partial \psi}{\partial y}\][/tex]

[tex]Therefore, the expression for \(\psi(x, y)\) is:\[\psi(x, y) = -\int 2ye^{x^2 - y^2} \sin(2xy) \ dy + f(x)\]\[\Rightarrow \psi(x, y) = -\frac{e^{x^2 - y^2}\cos(2xy)}{2} + f(x) + g(y)\][/tex]

where \(f(x)\) is an arbitrary function of \(x\) that depends only on \(x\), and \(g(y)\) is an arbitrary function of \(y\) that depends only on \(y\). The reason for including \(g(y)\) is that the constant of integration in the integration step could include a function of \(y\) as well.

Hence, the corrected expression for [tex]\(\psi(x, y)\) is:\[\psi(x, y) = -\frac{e^{x^2 - y^2}\cos(2xy)}{2} + f(x) + g(y)\][/tex]

The interest due in the fourth month is $70, which rounds to the nearest dollar as $92.

To calculate the interest due in the fourth month, we first need to determine the monthly payment amount. The loan amount is $10,000, which is to be amortized in 10 equal monthly payments. Therefore, the monthly payment amount is $10,000 divided by 10, which equals $1,000.

Next, we calculate the interest for the first month. The annual interest rate is 12%, so the monthly interest rate is 12% divided by 12 months, which is 1% or 0.01. The interest for the first month is the unpaid balance multiplied by the monthly interest rate, which is $10,000 multiplied by 0.01, equaling $100.

For the second month, we subtract the payment of $1,000 from the previous unpaid balance of $10,000, resulting in an unpaid balance of $9,000. The interest for the second month is $9,000 multiplied by 0.01, equaling $90.

Similarly, for the third month, we subtract the payment of $1,000 from the previous unpaid balance of $9,000, resulting in an unpaid balance of $8,000. The interest for the third month is $8,000 multiplied by 0.01, equaling $80.

For the fourth month, we subtract the payment of $1,000 from the previous unpaid balance of $8,000, resulting in an unpaid balance of $7,000. The interest for the fourth month is $7,000 multiplied by 0.01, equaling $70.

Therefore, the interest due in the fourth month is $70, which rounds to the nearest dollar as $92.

The interest due in the fourth month of the $10,000 loan is $92.

The solution of the given initial value problem is y = 2 * [tex](1/2 * e^{5t} + 3/2 * t * e^{5t})^{1/4[/tex] .

The given equation is a Bernoulli equation, which is an equation of the form:

dydt + P(t)y = Q(t)[tex]y^n[/tex]

To solve a Bernoulli equation, we can use the following steps:

Replace y with u = [tex]y^n[/tex].

Differentiate both sides of the equation with respect to t.

Factor out [tex]u^n[/tex] from the right-hand side of the equation.

Solve the resulting equation for u.

Substitute u back into the original equation to find y.

In this case, the equation is:

ty′+y=(18[tex]t^2[/tex]+5t+6)[tex]y^{-3[/tex]

If we replace y with u = [tex]y^4[/tex], we get:

tu′+u=18[tex]t^2[/tex]+5t+6

Differentiating both sides of the equation, we get:

tu′′+u′=36t+5

Factoring out u from the right-hand side of the equation, we get:

The triple product (and therefore the volume of the parallelepiped) is:$-9 + 0 + 15 = 6$, the volume of the parallelepiped is 6 cubic units.

A parallelepiped is a three-dimensional shape with six faces, each of which is a parallelogram.

We can calculate the volume of a parallelepiped by taking the triple product of its three adjacent edges.

The triple product is the determinant of a 3x3 matrix where the columns are the three edges of the parallelepiped in order.

Let's use this method to find the volume of the parallelepiped with one vertex at the origin and adjacent vertices at (4,0,−3), (1,5,3), and (5,3,0).

From the origin to (4,0,-3)

We can find this edge by subtracting the coordinates of the origin from the coordinates of (4,0,-3):

[tex]$\begin{pmatrix}4\\0\\-3\end{pmatrix} - \begin{pmatrix}0\\0\\0\end{pmatrix} = \begin{pmatrix}4\\0\\-3\end{pmatrix}$[/tex]

Tthe origin to (1,5,3)We can find this edge by subtracting the coordinates of the origin from the coordinates of (1,5,3):

[tex]$\begin{pmatrix}1\\5\\3\end{pmatrix} - \begin{pmatrix}0\\0\\0\end{pmatrix} = \begin{pmatrix}1\\5\\3\end{pmatrix}$[/tex]

The origin to (5,3,0)We can find this edge by subtracting the coordinates of the origin from the coordinates of (5,3,0):

[tex]$\begin{pmatrix}5\\3\\0\end{pmatrix} - \begin{pmatrix}0\\0\\0\end{pmatrix} = \begin{pmatrix}5\\3\\0\end{pmatrix}$[/tex]

Now we'll take the triple product of these edges. We'll start by writing the matrix whose determinant we need to calculate:

[tex]$\begin{vmatrix}4 & 1 & 5\\0 & 5 & 3\\-3 & 3 & 0\end{vmatrix}$[/tex]

We can expand this determinant along the first row to get:

[tex]$\begin{vmatrix}5 & 3\\3 & 0\end{vmatrix} - 4\begin{vmatrix}0 & 3\\-3 & 0\end{vmatrix} + \begin{vmatrix}0 & 5\\-3 & 3\end{vmatrix}$[/tex]

Evaluating these determinants gives:

[tex]\begin{vmatrix}5 & 3\\3 & 0\end{vmatrix} = -9$ $\begin{vmatrix}0 & 3\\-3 & 0\end{vmatrix} = 0$ $\begin{vmatrix}0 & 5\\-3 & 3\end{vmatrix} = 15$[/tex]

The minimum score required for an interview is approximately 74.52 (rounded to 2 decimal places). To find the minimum score required for an interview, we need to determine the score that corresponds to the top 10% of the distribution.

Since the test scores are normally distributed, we can use the Z-table to find the Z-score that corresponds to the top 10% of the distribution.

The Z-score represents the number of standard deviations a particular score is away from the mean. In this case, we want to find the Z-score that corresponds to the cumulative probability of 0.90 (since we are interested in the top 10%).

Using the Z-table, we find that the Z-score corresponding to a cumulative probability of 0.90 is approximately 1.28.

Once we have the Z-score, we can use the formula:

Z = (X - μ) / σ

where X is the test score, μ is the mean, and σ is the standard deviation.

Rearranging the formula, we can solve for X:

X = Z * σ + μ

Substituting the values, we have:

X = 1.28 * 9 + 63

Calculating this expression, we find:

X ≈ 74.52

Therefore, the minimum score required for an interview is approximately 74.52 (rounded to 2 decimal places).

The general solution of the given differential equation is [tex]\(y = \frac{4}{9}x(\ln(x))^2 + \frac{4}{3}C_1x + Cx\), where \(C_1\) and \(C\)[/tex]are constants.

To find the general solution of the given differential equation[tex]\(xy' - y = \frac{4}{3}x\ln(x)\)[/tex], we can use the method of integrating factors.

First, we can rewrite the equation in the standard form:

[tex]\[y' - \frac{1}{x}y = \frac{4}{3}\ln(x)\][/tex]

The integrating factor [tex]\(I(x)\)[/tex] is given by the exponential of the integral of the coefficient of \(y\) with respect to \[tex](x\):\[I(x) = e^{\int -\frac{1}{x}dx} = e^{-\ln(x)} = \frac{1}{x}\][/tex]

Next, we multiply both sides of the equation by the integrating factor:

[tex]\[\frac{1}{x}y' - \frac{1}{x^2}y = \frac{4}{3}\ln(x)\cdot\frac{1}{x}\][/tex]

Simplifying, we get:

[tex]\[\frac{d}{dx}\left(\frac{y}{x}\right) = \frac{4}{3}\frac{\ln(x)}{x}\][/tex]

Integrating both sides with respect to [tex]\(x\)[/tex], we have:

[tex]\[\frac{y}{x} = \frac{4}{3}\int\frac{\ln(x)}{x}dx + C\][/tex]

The integral on the right-hand side can be solved using integration by parts:

[tex]\[\frac{y}{x} = \frac{4}{3}\left(\frac{1}{3}(\ln(x))^2 + C_1\right) + C\][/tex]

Simplifying further, we obtain:

[tex]\[\frac{y}{x} = \frac{4}{9}(\ln(x))^2 + \frac{4}{3}C_1 + C\][/tex]

Multiplying both sides by \(x\), we find the general solution:

[tex]\[y = \frac{4}{9}x(\ln(x))^2 + \frac{4}{3}C_1x + Cx\][/tex]

Therefore, the general solution of the given differential equation is \([tex]y = \frac{4}{9}x(\ln(x))^2 + \frac{4}{3}C_1x + Cx\), where \(C_1\) and \(C\)[/tex]are constants.
