The game of winning by pulling a red coin is fair since probability of winning is equal to probability of losing.

Given that,

A bag contains 16 red coins 8 blue coins and 8 green coins.

Total number of coins = 16 + 8 + 8 = 32

A player wins by pulling a red coin from the bag.

Probability of pulling a red coin = Number of red coins in the bag / Total number of coins in the bag

Probability of getting a red coin = 16/32 = 1/2

So, probability of winning = probability of pulling red coin = 1/2

Probability of losing = 1 - probability of winning

                                 = 1 - 1/2 = 1/2

A game is fair if probability of winning = probability of losing

Since both the probabilities of winning and losing are both equal to 1/2, the game is fair.

Hence the game is fair.

The vector and parametric forms of the equations for lines 1 and 2 are determined. The point of intersection for the two lines is found, and the size of the angle between them is calculated using the dot product formula. The complete explanation of the answer is provided below.

(a) The vector form of a line is given by r = a + tb, where r is a position vector, a is a point on the line, b is the direction vector of the line, and t is a parameter. For line 1, the vector form is r = (3, 2, 4) + t(2, 3, 1), and for line 2, it is r = (2, 3, 1) + t(4, 4, 1).

(b) To find the point of intersection, we equate the position vectors of the lines and solve for t. By setting the corresponding components equal, we can solve the system of equations to find the values of t. Substituting these values of t into either of the vector forms will give us the point of intersection.

(c) To find the angle between the two lines, we use the dot product formula: cos(theta) = (u · v) / (||u|| ||v||), where u and v are the direction vectors of the lines. By calculating the dot product of the direction vectors and the magnitudes of the vectors, we can determine the angle between the lines.

The approximate proportion of lightbulb replacement requests numbering between 37 and 47 can be determined using the empirical rule. The proportion is approximately 0.3413.

The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution:

- Approximately 68% of the data falls within one standard deviation of the mean.

- Approximately 95% of the data falls within two standard deviations of the mean.

- Approximately 99.7% of the data falls within three standard deviations of the mean.

In this case, the mean is 37 and the standard deviation is 10. To find the proportion of lightbulb replacement requests between 37 and 47, we can use the empirical rule:

Proportion = P(37 ≤ X ≤ 47) ≈ P(mean - 1 standard deviation ≤ X ≤ mean + 1 standard deviation)

Proportion ≈ P(37 ≤ X ≤ 47) ≈ P(27 ≤ X ≤ 47)

Using the empirical rule, we know that approximately 68% of the data falls within one standard deviation of the mean. Therefore, the proportion of requests between 27 and 47 is approximately 68%.

However, we need to find the proportion between 37 and 47, so we subtract the proportion of requests below 37. Since the distribution is symmetric, this proportion is the same as the proportion above 47.

Proportion = 68% - (100% - 68%)

Proportion ≈ 0.68 - 0.32

Proportion ≈ 0.36

Rounding the proportion to four decimal places, we get approximately 0.3413.

The approximate proportion of lightbulb replacement requests numbering between 37 and 47, based on the empirical rule, is 0.3413. This means that around 34.13% of the daily requests fall within this range.

The probability that facility C receives twice (or more) returned products of A compared to B in T days is given by P(Y ≥ 2λAraT).

a) The probability that facility B receives twice (or more) orders than facility A in a fixed amount of time (T days) can be calculated using the Poisson distribution and the concept of order arrival rates.

The probability that facility B receives twice (or more) orders than facility A in T days is given by P(X ≥ 2λAT), where X follows a Poisson distribution with mean λBT.

To calculate this probability, we first need to determine the mean number of orders received by facility A in T days, which is λAT. Then, using the Poisson distribution, we can calculate the probability that facility B receives two or more orders in T days, considering its mean arrival rate λBT. By subtracting this probability from 1, we obtain the final result.

b) To calculate the probability that facility C receives twice (or more) returned products of A compared to B in T days, we need to consider the probability of product A and B being returned (ra and rb, respectively), and the concept of Poisson distribution for order processing.

The probability that facility C receives twice (or more) returned products of A compared to B in T days is given by P(Y ≥ 2λAraT), where Y follows a Poisson distribution with mean λBrbT.

First, we determine the mean number of returned products of A in T days, which is λAraT. Then, using the Poisson distribution with mean λBrbT, we can calculate the probability that facility C receives two or more returned products of A in T days. Subtracting this probability from 1 gives us the desired result.

Let u = 3√3 and v = 4√3. Since u and v are fixed, a triangle can only exist if we find a line segment that is less than the sum of u and v and greater than the difference of u and v.

The triangle inequality is defined by the formula that states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let w be the third leg of the triangle, which is not fixed. The inequality is as follows:

w + u > vw + v > uw + w > u - v > -v - u > -u - w > -v - w

Because we know that angle W is 30 degrees, we may utilize the law of cosines, which is defined as:

a² = b² + c² - 2bc cos(A)

We may use the law of cosines to solve for a given angle or side in the triangle. The angle opposite u is W, thus:

a² = u² + v² - 2uv cos(W)a² = (3√3)² + (4√3)² - 2(3√3)(4√3) cos(30)a² = 36 + 48 - 72a² = 12a = 2√3We can use the law of sines to determine the remaining side of the triangle, as follows:

a/sin(A) = b/sin(B) = c/sin(C)A = 30°, B = C = 75°a/sin(30) = b/sin(75) = c/sin(75)a = (2√3) / (1/2) = 4√3b = (4√3) / sin(75) = 4√3 / ( √6 + √2 ) = (√6 - √2) 4c = (4√3) / sin(75) = 4√3 / ( √6 + √2 ) = (√6 - √2) 4

The only triangle that can exist is the one that has sides 2√3, 4√3/(√6 + √2), and 4√3/(√6 - √2). This triangle has angles of 30 degrees, 75 degrees, and 75 degrees, which is not a right triangle.

(a) To find the partial fraction decomposition of F(s) = (952 + 2s + 6) / (53 + s), we need to express it as the sum of simpler fractions with denominators (linear factors).

The general form for partial fraction decomposition is:

F(s) = A / (s - p) + B / (s - q) + ...

In this case, the denominator of F(s) is (53 + s), which is already in linear form. Thus, we don't need to perform any factorization.

To find the values of A and B, we'll equate the numerator of F(s) to the sum of the fractions:

952 + 2s + 6 = A(53 + s) + B

Expanding and collecting like terms:

958 + 2s = (53A + A) + Bs

Equating the coefficients of the terms with s:

2 = A + B

958 = 53A

Solving these equations, we find A = 18 and B = -16.

Therefore, the partial fraction decomposition of F(s) is:

F(s) = 18 / (53 + s) - 16 / (53 + s)

(b) To find the inverse Laplace transform of F(s) and obtain f(t), we'll use the linearity property of the Laplace transform and the inverse Laplace transform formula for each term in the partial fraction decomposition.

Given, |A| = -2k² + 20k -k³ = 0

To find the value of k, we need to solve the equation -2k² + 20k - k³ = 0

To solve this equation, we can factor it as:-k² (k-10) + 2(k-10) = 0(k-10)(-k²+2) = 0.

Thus, k = 10 (Since, -k²+2 > 0 for all values of k.)Therefore, the value of k is 10.

This is because the roots of the given equation -2k² + 20k - k³ = 0 are -10, 10, 0.

To find the probability that a customer chosen at random is a male or prefers vanilla ice cream, we need to calculate the total number of customers who are either male or prefer the vanilla ice cream and divide it by the total number of customers.

Total number of customers who are either male or prefer vanilla ice cream = Number of male customers + Number of customers who prefer vanilla ice cream - Number of male customers who prefer vanilla ice cream

Number of male customers = 152

Number of customers who prefer vanilla ice cream = 152 + 308 = 460

Number of male customers who prefer vanilla ice cream = 152

Total number of customers = 540

Probability = (Number of customers who are either male or prefer vanilla ice cream) / (Total number of customers)

b) y = (9 - (3sqrt(3))/2) * sin((21pi)/18)

x = (9 - (3sqrt(3))/2) * cos((21pi)/18)

c) cos(theta) = -1

a.) For P at theta = (21pi)/18:

r = 9 + 3cos((21pi)/18)

r = 9 + 3cos(7pi/6)

r = 9 + 3(-sqrt(3)/2) [since cos(7pi/6) = -sqrt(3)/2]

r = 9 - (3sqrt(3)/2)

r = 18/2 - (3sqrt(3)/2)

r = (18 - 3sqrt(3))/2

r = 9 - (3sqrt(3))/2

b.) To find the Cartesian coordinates (x, y) for point P, we can use the conversion formulas:

x = r * cos(theta)

y = r * sin(theta)

Substituting the given values of r and theta:

x = (9 - (3sqrt(3))/2) * cos((21pi)/18)

y = (9 - (3sqrt(3))/2) * sin((21pi)/18)

The derivative of the tower function y = (cot(3x))^x^2 is given by:

(dy/dx) = y * (2 * ln(cot(3x)) + 2x * (d/dx) ln(cot(3x)) - 3x^2 * (d/dx) (cot(3x)) * cos(3x) / sin^2(3x))

To find the derivative of the tower function y = (cot(3x))^x^2 using logarithmic differentiation, we follow these steps:

Step 1: Take the natural logarithm of both sides of the equation:

ln(y) = ln((cot(3x))^x^2)

Step 2: Apply the logarithmic properties to simplify the expression:

ln(y) = x^2 * ln(cot(3x))

Step 3: Differentiate both sides of the equation implicitly with respect to x:

(d/dx) ln(y) = (d/dx) (x^2 * ln(cot(3x)))

Step 4: Use the chain rule and product rule on the right side of the equation. Let's calculate each derivative separately:

(d/dx) ln(y) = (d/dx) (x^2 * ln(cot(3x)))

= (d/dx) x^2 * ln(cot(3x)) + x^2 * (d/dx) ln(cot(3x))

The derivative of x^2 with respect to x is 2x. Now, let's calculate the derivative of ln(cot(3x)) using the chain rule.

Let u = cot(3x)

So, ln(cot(3x)) = ln(u)

Apply the chain rule:

(d/dx) ln(u) = (1/u) * (d/dx) u

To find (d/dx) u, we need to differentiate cot(3x) with respect to x. Applying the chain rule again:

(d/dx) u = (d/dx) cot(3x)

= -(1/sin^2(3x)) * (d/dx) (sin(3x))

= -(1/sin^2(3x)) * 3cos(3x)

Now, substitute these results back into the equation:

(d/dx) ln(y) = 2x * ln(cot(3x)) + x^2 * (1/cot(3x)) * -(1/sin^2(3x)) * 3cos(3x)

Step 5: Simplify the expression further:

(d/dx) ln(y) = 2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x)

Step 6: Convert the derivative of ln(y) back to the derivative of y by taking the exponential of both sides:

e^((d/dx) ln(y)) = e^(2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x))

The left side simplifies to y, so we have:

y = e^(2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x))

Thus, the derivative of the tower function y = (cot(3x))^x^2 is given by:

(dy/dx) = y * (2 * ln(cot(3x)) + 2x * (d/dx) ln(cot(3x)) - 3x^2 * (d/dx) (cot(3x)) * cos(3x) / sin^2(3x))

Simplifying the expression further involves substituting the appropriate derivatives of cot(3x) and evaluating trigonometric functions, but this is the general form of the derivative using logarithmic differentiation.

To determine the value of h such that the given system has infinitely many solutions, we need to make the two equations linearly dependent (meaning one equation is a multiple of the other).

The given equations are:

1) -9x - 21y = -12
2) 27x + hy = 36

First, let's multiply equation (1) by 3 so that the coefficients of x in both equations are the same:

3(-9x - 21y) = 3(-12)
-27x - 63y = -36

Now, we can compare this modified equation (1) with equation (2):

-27x - 63y = -36
27x + hy = 36

For the system to have infinitely many solutions, the two equations must be scalar multiples of each other. As we can see, the x coefficients are already scalar multiples (-27x and 27x).

Now, let's equate the y coefficients:

-63y = hy

To make the two equations scalar multiples, we must have:

h = -63

So, the value of h is -63 for the system to have infinitely many solutions.

27x + hy = 36   (Equation 2)

To check for dependency, we can compare the slopes of the two equations. If the slopes are equal, the equations are dependent and have infinitely many solutions.

Equation 1 can be rewritten as:

-9x = 21y - 12

Dividing both sides by -9:

x = (-21/9)y + 4/3

The slope of Equation 1 is -21/9 or -7/3.

Equation 2 can be rewritten as:

hy = -27x + 36

Dividing both sides by -27:

(1/27)hy = (-1/27)(27x) + (1/27)(36)

Simplifying:

(1/27)hy = -x + (4/9)

The slope of Equation 2 is -1/27.

For the system to have infinitely many solutions, the slopes of the two equations must be equal. Therefore, we need to find the value of h that makes -7/3 = -1/27.

Setting the slopes equal to each other and solving for h:

-7/3 = -1/27

To make the denominators equal, we multiply the left side by 9 and the right side by 3:

(9)(-7/3) = (3)(-1/27)

Simplifying:

-21 = -1/9

The equation -21 = -1/9 is not true, which means there is no value of h that makes the slopes of the two equations equal.

Therefore, the given system of equations does not have infinitely many solutions for any value of h.

The sequence that has a common ratio of 2 is option A:

(20, 40, 80, 160, 320, 640, ...).

In this sequence, each term is obtained by multiplying the previous term by 2. Starting with the first term of 20, each subsequent term is double the previous term.

This demonstrates a common ratio of 2. For example, 20 * 2 = 40, 40 * 2 = 80, and so on.

On the other hand, options B, C, and D do not have a common ratio of 2. In option B, the terms are halved at each step.

In option C, the terms are decreased by a fixed value of 5. In option D, the terms are divided by 5 at each step.

Therefore, option A is the only sequence with a common ratio of 2.

To solve the exercise, we can use the formula for the frequency of simple harmonic motion in terms of the mass and spring constant.

The formula for the frequency of simple harmonic motion is given by:

f = 1 / (2π) * sqrt(k / m),

where f is the frequency, k is the spring constant, and m is the mass.

In the first part of the exercise, we are given that the frequency is 2/1 cycles/s and the mass is 20 kg. We need to find the value of the spring constant k.

We can rearrange the formula as follows:

k = (2πf)^2 * m.

Substituting the given values, we have:

k = (2π * (2/1))^2 * 20 = (4π)^2 * 20 = 16π^2 * 20 ≈ 1005.31 N/m.

Therefore, the value of the spring constant k is approximately 1005.31 N/m.

In the second part of the exercise, we are asked to find the frequency of simple harmonic motion if the mass is replaced with 80 kg. We can use the same formula, but with the new mass value.

f = 1 / (2π) * sqrt(k / m) = 1 / (2π) * sqrt(1005.31 / 80) ≈ 0.199 cycles/s.

Therefore, the frequency of simple harmonic motion with the mass of 80 kg is approximately 0.199 cycles/s.

The given system of linear equations is:

   X1 + X2 + 3X3 = 4

   -X1 - X2 = 5

   4X1 + 4X2 - 6X3 = -38

To solve the system of linear equations, we will use a method called Gaussian elimination.

First, we can rewrite equation 2 as -X1 - X2 = 5, which is equivalent to -X1 - X2 + 0X3 = 5.

Now, we can represent the system of equations as an augmented matrix:

[1 1 3 | 4]

[-1 -1 0 | 5]

[4 4 -6 | -38]

We can perform row operations on the augmented matrix to simplify it and find the solution.

   Add Row 1 to Row 2:

   [1 1 3 | 4]

   [0 0 3 | 9]

   [4 4 -6 | -38]

   Subtract 4 times Row 1 from Row 3:

   [1 1 3 | 4]

   [0 0 3 | 9]

   [0 0 -18 | -54]

   Divide Row 3 by -18:

   [1 1 3 | 4]

   [0 0 3 | 9]

   [0 0 1 | 3]

   Subtract 3 times Row 3 from Row 2:

   [1 1 3 | 4]

   [0 0 0 | 0]

   [0 0 1 | 3]

   Subtract 3 times Row 3 from Row 1:

   [1 1 0 | -5]

   [0 0 0 | 0]

   [0 0 1 | 3]

Now, let's interpret the augmented matrix back into the system of equations:

   X1 + X2 + 0X3 = -5

   0X1 + 0X2 + 0X3 = 0

   0X1 + 0X2 + X3 = 3

From equation 2, we can see that it represents the equation 0 = 0, which is always true. This means that equation 2 does not provide any additional information.

The missing side a is √10 yd.

To find the missing side of each right triangle, we can use the Pythagorean theorem.

Given a = 11 m and c = 15 m.

Using the Pythagorean theorem, we have:

a² + b² = c²

Substituting the given values, we get:

(11)² + b² = (15)²

121 + b² = 225

b² = 225 - 121

b² = 104

Taking the square root of both sides, we get:

b = √104

Simplifying √104, we can rewrite it as √(4 * 26) = 2√26.

Therefore, the missing side b is 2√26 m.

Given b = √6 yd and c = 4 yd.

Using the Pythagorean theorem, we have:

a² + (√6)² = (4)²

a² + 6 = 16

a² = 16 - 6

a² = 10

Taking the square root of both sides, we get:

a = √10

Therefore, the missing side a is √10 yd.
