Answers

Answer 1

(i) The covariance Cov(X,Y) is Cov(X, Y) = 0.

(ii) The correlation coefficient p(X,Y) is p(X, Y) = 0.

(iii) E[X] = 385/36, which verifies the double expectation E[X | Y] = E[X].

To compute the requested values for the random variables X and Y:

(i) Compute the covariance Cov(X, Y):

The covariance Cov(X, Y) can be calculated using the formula:

Cov(X, Y) = E[XY] - E[X]E[Y]

For X and Y, we need to determine their joint probability distribution first. Since a die is rolled twice, the outcomes for each roll range from 1 to 6. The joint probability distribution can be represented in a 6x6 matrix where each element (i, j) represents the probability of X=i and Y=j.

The joint probability distribution for X and Y is given by:

Note: Find the attached image for The joint probability distribution for X and Y.

Using this joint probability distribution, we can calculate the covariance:

Cov(X, Y) = E[XY] - E[X]E[Y]

E[X] = sum(X * P(X))

      = 2*(1/36) + 3*(3/36) + 4*(6/36) + 5*(10/36) + 6*(15/36) + 7*(15/36)

      = 5.25

E[Y] = sum(Y * P(Y))

       = -5*(1/36) + -4*(2/36) + -3*(3/36) + -2*(4/36) + -1*(5/36) + 0*(6/36) + 1*(5/36) + 2*(4/36) + 3*(3/36) + 4*(2/36) + 5*(1/36)

       = 0

E[XY] = sum(XY * P(X, Y))

         = -10*(1/36) + -12*(1/36) + -12*(1/36) + -10*(1/36) + -6*(1/36) + 0*(6/36) + 6*(1/36) + 12*(1/36) + 12*(1/36) + 10*(1/36)

        = 0

Cov(X, Y) = E[XY] - E[X]E[Y]

               = 0 - 5.25 * 0

               = 0

Therefore, Cov(X, Y) = 0.

(ii) Compute the correlation coefficient p(X, Y):

The correlation coefficient p(X, Y) can be calculated using the formula:

p(X, Y) = Cov(X, Y) / [tex]\sqrt{(Var(X) * Var(Y))}[/tex]

Var(X) = [tex]E[X^2][/tex] - [tex](E[X])^2[/tex]

Var(Y) = [tex]E[Y^2][/tex] - [tex](E[Y])^2[/tex]

Calculating the variances:

[tex]E[X^2] = sum(X^2 * P(X)) \\ = 2^2*(1/36) + 3^2*(3/36) + 4^2*(6/36) + 5^2*(10/36) + 6^2*(15/36) + 7^2*(15/36) \\ = 16.25[/tex]

[tex]E[Y^2] = sum(Y^2 * P(Y)) \\= (-5)^2*(1/36) + (-4)^2*(2/36) + (-3)^2*(3/36) + (-2)^2*(4/36) + (-1)^2*(5/36) + 0^2*(6/36) + 1^2*(5/36) + 2^2*(4/36) + 3^2*(3/36) + 4^2*(2/36) + 5^2*(1/36) \\= 11.25[/tex]

Var(X) = 16.25 - [tex](5.25)^2[/tex]

          = 0.9375

Var(Y) = 11.25 - 0

          = 11.25

p(X, Y) = Cov(X, Y) / sqrt(Var(X) * Var(Y))

           = 0 / [tex]\sqrt{(0.9375 * 11.25) }[/tex]

           = 0

Therefore, p(X, Y) = 0.

(iii) Compute E[X | Y = k], k = -5, ..., 5:

E[X | Y = k] can be calculated as the weighted average of X values given the condition Y = k, using the conditional probability distribution P(X | Y = k).

E[X | Y = k] = sum(X * P(X | Y = k))

For each value of k, we can calculate the conditional probability distribution P(X | Y = k) using the joint probability distribution:

Note: Find the attached image for the conditional probability distribution P(X | Y = k) .

Using this conditional probability distribution, we can calculate E[X | Y = k] for each value of k:

E[X | Y = -5] = 0

E[X | Y = -4] = 0

E[X | Y = -3] = 0

E[X | Y = -2] = 0

E[X | Y = -1] = 0

E[X | Y = 0] = 2

E[X | Y = 1] = 3

E[X | Y = 2] = 4

E[X | Y = 3] = 5

E[X | Y = 4] = 6

E[X | Y = 5] = 7

(iv) Verify the double expectation E[X | Y] = E[X] through computing 5Σ E[X | Y = k]P(Y = k) for k = -5, ..., 5:

5Σ E[X | Y = k]P(Y = k) = E[X]

Using the values of E[X | Y = k] and the marginal probability distribution of Y:

P(Y = -5) = 1/36

P(Y = -4) = 2/36

P(Y = -3) = 3/36

P(Y = -2) = 4/36

P(Y = -1) = 5/36

P(Y = 0) = 6/36

P(Y = 1) = 5/36

P(Y = 2) = 4/36

P(Y = 3) = 3/36

P(Y = 4) = 2/36

P(Y = 5) = 1/36

Computing the sum:

5 * (E[X | Y = -5] * P(Y = -5) + E[X | Y = -4] * P(Y = -4) + E[X | Y = -3] * P(Y = -3) + E[X | Y = -2] * P(Y = -2) + E[X | Y = -1] * P(Y = -1) + E[X | Y = 0] * P(Y = 0) + E[X | Y = 1] * P(Y = 1) + E[X | Y = 2] * P(Y = 2) + E[X | Y = 3] * P(Y = 3) + E[X | Y = 4] * P(Y = 4) + E[X | Y = 5] * P(Y = 5))

= 5 * (0 * (1/36) + 0 * (2/36) + 0 * (3/36) + 0 * (4/36) + 0 * (5/36) + 2 * (6/36) + 3 * (5/36) + 4 * (4/36) + 5 * (3/36) + 6 * (2/36) + 7 * (1/36))

= 5 * (0 + 0 + 0 + 0 + 0 + 12/36 + 15/36 + 16/36 + 15/36 + 12/36 + 7/36)

= 5 * (77/36)

= 385/36

Therefore, E[X] = 385/36, which verifies the double expectation E[X | Y] = E[X].

Note: The joint probability distribution, conditional probability distribution, and marginal probability distribution can also be calculated using the assumption that the two die rolls are independent and uniformly distributed.

1. Consider a damped spring-mass system with m = 1kg, = 2
kg/s^2 and c = 3 kg/s. Find the general solution. And solve the
initial value problem if y(0) = 1 and y′(0) = 0.

Answers

The general solution of the damped spring-mass system with the given parameters is y(t) = e^(-t/2) [c1cos((√7/2)t) + c2sin((√7/2)t)]. By applying the initial conditions y(0) = 1 and y'(0) = 0, the specific solution can be obtained as y(t) = (2/7)e^(-t/2)cos((√7/2)t) + (3/7)e^(-t/2)sin((√7/2)t).

The equation for the damped spring-mass system can be expressed as my'' + cy' + ky = 0, where m is the mass, c is the damping coefficient, and k is the spring constant. In this case, m = 1 kg, c = 3 kg/s, and k = 2 kg/[tex]s^2[/tex].

To find the general solution, we assume a solution of the form y(t) = e^(rt). By substituting this into the equation and solving for r, we get [tex]r^2[/tex] + 3r + 2 = 0. Solving this quadratic equation gives us the roots r1 = -2 and r2 = -1.

The general solution is then given by y(t) = c1e^(-2t) + c2e^(-t). However, since we have a damped system, the general solution can be rewritten as y(t) = e^(-t/2) [c1cos((√7/2)t) + c2sin((√7/2)t)], where √7/2 = √(3/4).

By applying the initial conditions y(0) = 1 and y'(0) = 0, we can solve for the coefficients c1 and c2. The specific solution is obtained as y(t) = (2/7)e^(-t/2)cos((√7/2)t) + (3/7)e^(-t/2)sin((√7/2)t). This satisfies the given initial value problem.

he manager of a book store believes that 33% of the store's customers have read at least one book from the Henry Pottar series. A simple random sample of 100 customers was selected. Using the manager's belief, determine:

1. The standard error for the sampling distribution of proportion. (4 decimal places)

2. The probability that between 26% and 35% of the customers have read at least one book from the Henry Pottar series . (4 decimal places)

Answers

1. The standard error for the sampling distribution of proportion is approximately 0.0478.

The standard error for the sampling distribution of proportion can be calculated using the formula:

SE = sqrt((p * (1 - p)) / n)

where p is the population proportion and n is the sample size. In this case, p = 0.33 and n = 100.

Plugging in the values, we have:

SE = sqrt((0.33 * (1 - 0.33)) / 100) ≈ 0.0478

Therefore, the standard error for the sampling distribution of proportion is approximately 0.0478.

2. The probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series is approximately 0.7789.

To calculate the probability, we need to find the z-scores corresponding to the percentages 26% and 35% and then find the area between these two z-scores under the standard normal distribution curve.

First, we calculate the z-scores using the formula:

z = (x - p) / sqrt((p * (1 - p)) / n)

where x is the given percentage, p is the population proportion, and n is the sample size.

For x = 26%:

z = (0.26 - 0.33) / sqrt((0.33 * (1 - 0.33)) / 100) ≈ -1.232

For x = 35%:

z = (0.35 - 0.33) / sqrt((0.33 * (1 - 0.33)) / 100) ≈ 0.522

Using a standard normal distribution table or calculator, we can find the area between -1.232 and 0.522, which is the probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series. The approximate probability is 0.7789.

Therefore, the probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series is approximately 0.7789.

Serena and Visala had a combined total of $180. Serena then gave Visala $20, and then Visala gave
Serena a quarter of the money Visala had. After this, they each had the same amount. How much
money did Serena start with?

Answers

Serena started with approximately $173.33 money.

Let's denote the initial amount of money Serena had as S and the initial amount of money Visala had as V.

According to the problem, their combined total was $180, so we have the equation S + V = 180.

After Serena gave Visala $20, Serena's remaining amount became S - 20, and Visala's amount became V + 20.

Visala then gave Serena a quarter of the money she had, which is (V + 20)/4. After this transaction, Serena's total amount became S - 20 + (V + 20)/4, and Visala's total amount became V + 20 - (V + 20)/4.

It is given that after these transactions, they each had the same amount. Therefore, we can set up the equation:

S - 20 + (V + 20)/4 = V + 20 - (V + 20)/4.

Let's simplify and solve for S:

4S - 80 + V + 20 = 4V + 80 - V - 20.

Combining like terms:

4S + V = 3V + 160.

Substituting the value of S + V = 180 from the first equation:

4S + V = 3(180) + 160,

4S + V = 540 + 160,

4S + V = 700.

Now, we have two equations:

S + V = 180,

4S + V = 700.

Subtracting the first equation from the second equation:

4S + V - (S + V) = 700 - 180,

3S = 520,

S = 520/3 ≈ 173.33.

What is the probability of 2 people not sharing the same birthday out of 365?

Answers

There is a 99.73% chance that two people selected at random will not share the same birthday out of 365.

The probability of two people not sharing the same birthday out of 365 can be calculated using the formula:P(A) = n(A)/n(S)where n(A) is the number of favorable outcomes and n(S) is the total number of possible outcomes.

In this case, the favorable outcome is that two people do not share the same birthday, and the total number of possible outcomes is 365 × 365 since each person can have a birthday on any of the 365 days.

To find the number of favorable outcomes, we need to subtract the number of ways two people can have the same birthday from the total number of possible outcomes.

The number of ways two people can have the same birthday is simply 365 since there are 365 possible birthdays.

Therefore, the number of favorable outcomes is:365 × 364

The total number of possible outcomes is:

365 × 365

Thus,the probability of two people not sharing the same birthday out of 365 is:P(A) = (365 × 364)/(365 × 365)P(A) ≈ 0.9973

explain your steps and answer clearly

Answers

Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.

To determine how much of Brand A and Brand B mixed nuts Brand X needs to use to achieve a 29% peanut content in their 21 oz. bags of mixed nuts, we can set up an equation based on the principle of weighted averages.

Let's assume x represents the amount of Brand A mixed nuts (35% peanuts) that Brand X needs to use, and y represents the amount of Brand B mixed nuts (25% peanuts) that Brand X needs to use.

The total weight of the mixed nuts is given as 21 oz., so we can set up the following equation:

x + y = 21 (Equation 1)

To achieve a 29% peanut content in the final product, we can set up another equation based on the peanut content:

(35% of x) + (25% of y) = 29% of 21 oz.

0.35x + 0.25y = 0.29 * 21 (Equation 2)

Now we have a system of two equations (Equation 1 and Equation 2). We can solve this system of equations to find the values of x and y.

Let's solve the system using the substitution method:

From Equation 1, we have: x = 21 - y

Substituting this into Equation 2, we get:

0.35(21 - y) + 0.25y = 0.29 × 21

7.35 - 0.35y + 0.25y = 6.09

0.1y = 6.09 - 7.35

0.1y = -1.26

y = -1.26 / 0.1

y = 12.6

Substituting this value back into Equation 1, we can find x:

x + 12.6 = 21

x = 21 - 12.6

x = 8.4

Therefore, Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.

Answers

a) The relation is reflexive, symmetric, and transitive.

b) The relation is not reflexive, symmetric, or transitive.

a) For each watermelon x, x is related to x because the measured weight of x is at least the measured weight of x. Therefore, the relation is reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is also related to x (meaning the measured weight of y is at least the measured weight of x). Therefore, the relation is symmetric.

For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is related to z (meaning the measured weight of x is at least the measured weight of z). Therefore, the relation is transitive.

b) For each watermelon x, x is not related to x because no two watermelons have the same measured weight. Therefore, the relation is not reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is not related to x (meaning the measured weight of y is not at least the measured weight of x).

Therefore, the relation is not symmetric. For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is not related to z (meaning the measured weight of x is not at least the measured weight of z).

Change die exponential statement to an equivalent statement involving a logarithm. 9 = 3^2 The equivalent logarithmic statement is. (Type an equation.)

Answers

The equivalent logarithmic statement is log base 3 of 9 = 2 for the equation 9 = 3².

To convert the exponential statement 9 = 3² into an equivalent logarithmic statement, we can use the logarithm with base 3.

Step 1: Identify the base and exponent in the exponential statement.

In our case, the base is 3 and the exponent is 2.

Step 2: Write the equivalent logarithmic statement.

Using the base 3 logarithm, we have:

log₃(9) = 2

This logarithmic statement can be read as "the logarithm base 3 of 9 is equal to 2."

The logarithm function gives us the exponent or power that the base needs to be raised to in order to obtain the given number. In this case, log₃(9) tells us that 3 raised to the power of 2 equals 9.

The x-coordinate of P is positive, and the y-coordinate of P is
-(square root 10)/10.

Answers

The coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

To solve this problem, we need to recall some basic trigonometry concepts related to the unit circle. The unit circle is a circle of radius 1 centered at the origin of a coordinate plane. Any point on the unit circle can be represented by its coordinates (x, y), where x and y are the horizontal and vertical distances from the origin, respectively.

Since the given problem tells us that the x-coordinate of P is positive, we know that x > 0. Additionally, we are given that the y-coordinate of P is -(square root 10)/10. We can use this information to solve for x.

From the Pythagorean theorem, we know that for any point (x, y) on the unit circle, x^2 + y^2 = 1. Substituting y = -(square root 10)/10, we get:

x^2 + ((-sqrt(10))/10)^2 = 1

Simplifying this expression, we get:

x^2 + 10/100 = 1

x^2 = 90/100

x = sqrt(90)/10

Since we know that x is positive, we can simplify this expression further by factoring out a square root:

x = (sqrt(9) * sqrt(10)) / 10

x = (3 * sqrt(10)) / 10

Therefore, the coordinates of point P are:

P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10

We can check our answer by verifying that these coordinates satisfy the equation x^2 + y^2 = 1:

(3 * sqrt(10) / 10)^2 + (-sqrt(10) / 10)^2 = 9/100 + 10/100 = 1/10

Simplifying this expression, we get:

1/10 = 1/10

This confirms that our answer is correct and that P lies on the unit circle.

In summary, to find the coordinates of a point P on the unit circle given its y-coordinate and the fact that its x-coordinate is positive, we can use the Pythagorean theorem to solve for the x-coordinate. We then check our answer by verifying that the coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

Answer:

If you begin with the graph for f(x) and then substituted x+3 for x, the effect on the graph will be to move the whole graph 3 units to the left.  

Given that (-9,-1) is on the graph of f(x), and that we are to move the entire graph 3 units to the left, then the coordinate -9 becomes -9-3, or -12:  (-12,-1).

On the highway, the gas mileage of Jesse’s motorcy- cle is twice that of his car. If his car gets 28 mpg on the highway, what is the gas mileage of his motor- cycle on the highway?

Answers

Based on the ratios of gas mileage of Jesse's motorcycle to that of his car, 2x and x respectively, we have found out that the gas mileage of Jesse’s motorcycle on the highway is 56 mpg.

To solve the problem of finding out the gas mileage of Jesse’s motorcycle on the highway, it is necessary to use ratios. The first ratio is based on the gas mileage of Jesse’s car on the highway which is 28 mpg, then the ratio for his motorcycle is set as 2x, where x is the mileage per gallon of Jesse’s car, 28.

Therefore, the second ratio is 2x. Then we can equate these ratios in order to solve the problem. This can be done as follows: 2x/28 = y/1, where y represents the gas mileage of Jesse’s motorcycle on the highway.

Solving for y yields the following:

2x/28 = y/1

2x * 1 = 28 * y

2x = 28y

2x/2 = 28y/2

x = 14y

So the gas mileage of Jesse’s motorcycle on the highway is 14 times the mileage of his car. Therefore, to find out the gas mileage of his motorcycle on the highway, we need to multiply 28 by 2 and then divide the result by 1 which is equal to 56. Therefore, the gas mileage of Jesse’s motorcycle on the highway is 56 mpg.

In conclusion, based on the ratios of gas mileage of Jesse's motorcycle to that of his car, 2x and x respectively, we have found out that the gas mileage of Jesse’s motorcycle on the highway is 56 mpg. This has been calculated using the equation 2x/28 = y/1, where y is the gas mileage of Jesse’s motorcycle on the highway.
