To calculate E(X|Y), we need to find the conditional PDF of X given Y. Using the given joint PDF, we can find the conditional PDF as

  f(X|Y) = (6XY) / (3Y^2) = 2X / Y for 0 ≤ X ≤ Y.

Then, we can find the conditional expectation as

E(X|Y) = ∫X f(X|Y) dX, which evaluates to

E(X|Y) = 2/3 Y²

   2. Calculate Var(X|Y):

To calculate Var(X|Y), we need to first find the conditional expectation of X given Y, which we calculated in the previous step as

  E(X|Y) = 2/3 Y².

Then, we can find the conditional variance of X given Y as

  Var(X|Y) = E(X²|Y) - [E(X|Y)]²,

 where E(X²|Y) = ∫X² f(X|Y) dX.

After computing the integrals, we get

  Var(X|Y) = (2/5)[tex]Y^3[/tex] - (4/9)[tex]Y^4[/tex]

     3. Show that E[E(X|Y)] = E(X):

We can show that E[E(X|Y)] = E(X) using the "Conditional Probability" , which states that E(X) = E[E(X|Y)].

From the previous calculations, we know that E(X|Y) = 2/3 Y², and the marginal PDF of Y is f(Y) = 3Y² for 0 ≤ Y ≤ 1.

Therefore, we can compute E(E(X|Y)) as E(E(X|Y)) = ∫Y E(X|Y) f(Y) dY, which evaluates to E(E(X|Y)) = 2/5.

Also, we previously computed E(X) as E(X) = 3/2.

Therefore, we have E[E(X|Y)] = 2/5 and E(X) = 3/2, and

we can see that E[E(X|Y)] ≠ E(X).

This indicates that X and Y are dependent variables.

You can use inequality signs to show lower and upper bounds of a number.

For example:

Lower bound:

x ≥ 5 (means x is greater than or equal to 5)

Upper bound:

x ≤ 10 (means x is less than or equal to 10)

Together they show a range:

5 ≤ x ≤ 10 (means x is between 5 and 10)

Some other examples:

0 < x < 100 (means x is between 0 and 100)

-10 ≤ y ≤ 50 (means y is between -10 and 50)

-5 < z < 12.5 (means z is between -5 and 12.5)

To approximate the value of the series ∑n=1infinityn / (n^2)(n^6) within an error of at most 10^(-3), we can use the alternating series test and the remainder formula.

The series is alternating because the sign alternates between positive and negative. Moreover, the terms of the series are decreasing in absolute value because:

|(-1)^(n+1) / (n^2)(n^6)| < |(-1)^(n) / ((n+1)^2)((n+1)^6)| for all n

Therefore, we can apply the alternating series test and bound the error by the absolute value of the first neglected term:

|R_N| = |-1^(N+1) / (N+1)^2((N+1)^6)|

To find the smallest value of N that approximates S to within an error of at most 10^(-5), we need to solve the inequality:

|R_N| = |-1^(N+1) / (N+1)^2((N+1)^6)| ≤ 10^(-5)

Solving for N, we get:

N ≥ 14

Thus, the smallest value of N that approximates S to within an error of at most 10^(-5) is N=14.

To approximate S, we can sum the first 14 terms of the series:

S ≈ ∑n=114^n / (n^2)(n^6)

Using a calculator or a computer algebra system, we get:

The decision complexity advantage for 10 decisions with two alternatives compared to one decision with 20 alternatives is 3.31. This can be answered by the concept of Log.

To calculate the decision complexity advantage, we need to first plug in the given values for a and b into the formula RT = a + b log2(N), where N is the number of alternatives.

For 10 decisions with two alternatives each, N = 2¹⁰ = 1024. Thus, RT = 1 + 2 log2(1024) = 22 seconds.

For one decision with 20 alternatives, N = 20. Thus, RT = 1 + 2 log2(20) = 6.64 seconds.

The decision complexity advantage is calculated by taking the ratio of the RT values: 22/6.64 = 3.31. This means that making 10 decisions with two alternatives each is 3.31 times faster than making one decision with 20 alternatives.

Therefore, the decision complexity advantage for 10 decisions with two alternatives compared to one decision with 20 alternatives is 3.31.

Step-by-step explanation:

The slope of the parametric curve x=-[tex]2t^3[/tex]+7, y=3t² at the point corresponding to t is -1 divided by t.

To find the slope of the parametric curve x=-[tex]2t^3[/tex]+7, y=3t², we need to take the derivative of y with respect to x.

To do this, we can use the chain rule:

(dy/dx) = (dy/dt) / (dx/dt)

where (dx/dt) is the derivative of x with respect to t, and (dy/dt) is the derivative of y with respect to t.

Taking the derivatives, we get:

dx/dt = -6t²

dy/dt = 6t

Substituting these values, we get:

(dy/dx) = (dy/dt) / (dx/dt) = (6t) / (-6t²) = -1/t

So, the slope of the curve at the point corresponding to t is -1/t.

The value of c in the quadratic equation given is 32.

Given a quadratic equation of the form 3x² + bx + c = 0 has roots of 6 plus or minus square root of 2, we know that the quadratic equation can be written as:

3(x - (6 + √2))(x - (6 - √2)) = 0

Expanding this product gives:

3[(x - 6 - √2)(x - 6 + √2)] = 0

Using the difference of squares, we can simplify this expression to:

3[(x - 6)² - (√2)²] = 0

3(x - 6)² - 6 = 0

Multiplying out the squared term, we get:

3x² - 36x + 102 - 6 = 0

Simplifying, we get:

3x² - 36x + 96 = 0

Dividing both sides by 3, we get:

Answer:

interior angle = 58°; exterior angle = 122°

Step-by-step explanation:

For all polygons, an interior angle and its accompanying exterior angle are always supplementary and thus equal 180°.

Thus, we can first find g by making the sum of the equation given for the interior angle and the equation given for the exterior angle equal to 180 and solve for g:

[tex](2g+16)+(4g+38)=180\\2g+16+4g+38=180\\6g+54=180\\6g=126\\g=21[/tex]

Now, we can first find the measure of interior angle X by plugging in g for 21:

[tex]X=2(21)+16\\X=42+16\\X=58[/tex]

Finally, we can find the measure of the exterior angle by either plugging in g for the equation or simply by subtracting 58 from 180 since the interior and exterior angle are supplementary and equal 180:

Exterior angle = 180 - 58

Exterior angle = 122

The value of dy for y = [tex]e^{(x/10)}[/tex], x = 0, and dx = 0.1 is 0.01.

To evaluate the value of dy for the given values of x and dx, we first need to find the derivative of y with respect to x, which can be computed as follows:

[tex]y = e^{(x/10)}[/tex]

Differentiating both sides with respect to x using the chain rule, we get:

dy/dx = d/dx [[tex]y = e^{(x/10)}\\[/tex]]

=[tex]y = e^{x/10}[/tex] * d/dx [x/10]

= [tex]y = e^{(x/10)}[/tex] * (1/10) * d/dx [x]

=[tex]y = e^{(x/10)}[/tex] * (1/10)

Now, we substitute the values x = 0 and dx = 0.1 in the above expression to get the value of dy:

dy = (1/10) *[tex]e^{(0/10)}[/tex] * dx

= (1/10) * (1) * (0.1)

The solution to Ax=b using the LU factorization is: x = [27 -23/4 -30]

To find the solution to the system Ax=b using the LU factorization:

We need to first decompose the matrix A into its lower and upper triangular matrices L and U respectively, such that A = LU.

Using the given LU factorization of A, we can write:

L = [1 0 0] [1 0 0] [-1 3 1]

U = [2 3 4] [0 -4 3] [0 0 -1]

Next, we need to solve the system LY=b. We can substitute L and Y with their corresponding matrices and variables respectively:

[1 0 0] [1 0 0] [-1 3 1] [y1 y2 y3] = [4 17 43]

Simplifying this system, we get:

y1 = 4

y2 = 17

-y1 + 3y2 + y3 = 43

Solving for y3, we get:

y3 = 30

Now that we have the values for Y, we can solve the system Ux=Y to get the solution to Ax=b.

We can substitute U and X with their corresponding matrices and variables respectively:

[2 3 4] [0 -4 3] [0 0 -1] [x1 x2 x3] = [y1 y2 y3]

Simplifying this system, we get:

-4x2 + 3x3 = 17

-x3 = 30

Solving for x3, we get:

The indicated probabilities. f(x) = x in the interval [0, 2] is 1.

Explanation: -

Given the probability density function f(x), we need to find the indicated probabilities over the interval [0, 2].

f(x) is defined as follows:
f(x) = x if 0 ≤ x ≤ 1
f(x) = 2 - x if 1 ≤ x ≤ 2

Step 1: Check if f(x) is a valid probability density function.
To be a valid pdf, the integral of f(x) over the entire interval should be equal to 1.

Let's check that:

∫(0 to 1) x dx + ∫(1 to 2) (2 - x) dx

For the first integral, we have:
∫x dx = (1/2)x^2 evaluated from 0 to 1 = (1/2)(1)^2 - (1/2)(0)^2 = 1/2

For the second integral, we have:
∫(2 - x) dx = 2x - (1/2)x^2 evaluated from 1 to 2 = (2(2) - (1/2)(2)^2) - (2(1) - (1/2)(1)^2) = 1/2

Total probability = 1/2 + 1/2 = 1. Since the integral is equal to 1, f(x) is a valid probability density function.

Step 2: Find the probabilities for the interval [0, 2].
Since we're looking for probabilities over the entire interval, the answer is simply the integral of f(x) over [0, 2], which we've already found to be equal to 1.

Your answer: The elasticity of the demand function 2p 3q = 90 at the price p = 15 is -0.5.

To find the elasticity of the demand function, we need to use the following formula:

Elasticity = (dq/dp) * (p/q)

where dq/dp is the derivative of q with respect to p, and (p/q) is the ratio of the two variables at a given point.

First, we need to solve the demand function for q in terms of p:

2p + 3q = 90

3q = 90 - 2p

q = (90 - 2p)/3

Next, we need to find the derivative of q with respect to p:

dq/dp = (-2/3)

Finally, we can plug in the values for p and q to find the elasticity at p = 15:

q = (90 - 2(15))/3 = 20

(p/q) = 15/20 = 0.75

Elasticity = (-2/3) * (15/20) = -0.5

Therefore, the elasticity of the demand function 2p + 3q = 90 at the price p = 15 is -0.5. This means that a 1% increase in price would lead to a 0.5% decrease in quantity demanded.

The formula for average cost (AC) is:

AC = (Total cost / Quantity)

To find the total cost, we need to add the variable cost (VC) and the avoidable fixed cost:

Total cost = VC + Fixed cost

Total cost = 20Q + 50,000

Now we can substitute this into the formula for average cost:

AC = (Total cost / Quantity)

AC = (20Q + 50,000) / Q

Simplifying this expression gives:

AC = 50,000/Q + 20

The pressure exerted by the box on the shelf is given by the formula:

Pressure = Force / Area

where Pressure is measured in Newtons per square meter (N/m^2), Force is measured in Newtons (N), and Area is measured in square meters (m^2).

We are given that the pressure exerted by the box on the shelf is 200 N/m and the force that the box exerts on the shelf is 140 N. Using the formula above, we can solve for the area of the base of the box as follows:

200 N/m = 140 N / Area

Simplifying the equation above, we can multiply both sides by the Area to get:

Area * 200 N/m = 140 N

Dividing both sides by 200 N/m, we get:

Area = 140 N / 200 N/m

Simplifying the right-hand side, we get:

Area = 0.7 m^2

Therefore, the area of the base of the box is 0.7 square meters, or 0.7 m^2 to 1 decimal place.

Answer:

0.7 m²

Step-by-step explanation:

The pressure exerted by the box on the shelf is defined as the force per unit area, so we can use the formula:

[tex]\boxed{\sf Pressure = \dfrac{Force}{Area}}[/tex]

We need to determine the area of the base of the box, so we can rearrange the formula to solve for area:

[tex]\boxed{\sf Area= \dfrac{Force}{Pressure}}[/tex]

Given values:

Substitute the given values into the formula:

[tex]\implies \sf Area = \dfrac{140\;N}{200\;N\;m^{-2}}[/tex]

[tex]\implies \sf Area = \dfrac{140}{200}\;m^2[/tex]

[tex]\implies \sf Area = 0.7\;m^2[/tex]

Therefore, the area of the base of the box is 0.7 square meters.

Given that x is a continuous variable with the probability density function f(x) = c(10-x)^2 for 0 < x < 10, we need to find the value of c.

Step 1: Understand that for a probability density function, the total area under the curve must equal 1. Mathematically, this is expressed as:

∫[f(x)] dx = 1, with integration limits from 0 to 10.

Step 2: Substitute f(x) with the given function and integrate:

∫[c(10-x)^2] dx from 0 to 10 = 1

Step 3: Perform the integration:

c ∫[(10-x)^2] dx from 0 to 10 = 1

Step 4: Apply the power rule for integration:

c[(10-x)^3 / -3] from 0 to 10 = 1

Step 5: Substitute the integration limits:

c[(-1000)/-3 - (0)/-3] = 1

Step 6: Solve for c:

(1000/3)c = 1

c = 3/1000

c = 0.003

So the probability density function f(x) = 0.003(10-x)^2 for 0 < x < 10.

The minimum possible value of f ( 7 ) − f ( 3 ) f(7)-f(3) is −4 and the maximum possible value is 4.

Given that 2 ≤ f ' ( x ) ≤ 4 2≤f′(x)≤4 for all values of x, we can make use of the Mean Value Theorem to determine the minimum and maximum possible values of f ( 7 ) − f ( 3 ) f(7)-f(3).

According to the Mean Value Theorem, there exists a c ∈ ( 3 , 7 ) c\in(3,7) such that:

f ( 7 ) − f ( 3 ) = f ′ ( c ) ( 7 − 3 ) = 4 c − 12 4c-12

Since f'(x) is between 2 and 4 for all values of x, we know that 8 ≤ 4c ≤ 16 8\leq4c\leq16. Therefore, 2 ≤ c ≤ 4 2\leq c\leq 4.

To find the maximum value of f ( 7 ) − f ( 3 ) f(7)-f(3), we need to maximize 4c-12 when c is between 2 and 4. This occurs when c = 4, so the maximum value of f ( 7 ) − f ( 3 ) f(7)-f(3) is:

f ( 7 ) − f ( 3 ) ≤ 4 ( 4 ) − 12 = 4

To find the minimum value of f ( 7 ) − f ( 3 ) f(7)-f(3), we need to minimize 4c-12 when c is between 2 and 4. This occurs when c = 2, so the minimum value of f ( 7 ) − f ( 3 ) f(7)-f(3) is:

f ( 7 ) − f ( 3 ) ≥ 4 ( 2 ) − 12 = −4

Therefore, the minimum possible value of f ( 7 ) − f ( 3 ) f(7)-f(3) is −4 and the maximum possible value is 4.

All four requirements are satisfied and the given procedure does result in a binomial distribution. The answer is OC, "Yes, because all 4 requirements are satisfied."

The given procedure does result in a binomial distribution. The four requirements for a binomial distribution are:
1) The experiment consists of a fixed number of trials.
2) Each trial has only two possible outcomes, success or failure.
3) The trials are independent of each other.
4) The probability of success remains the same for each trial.

In this case, each mp3 player can either be acceptable or defective, so there are only two possible outcomes. The trials are independent of each other, and the probability of a player being acceptable or defective remains the same for each trial.

Therefore, all four requirements are satisfied and the given procedure does result in a binomial distribution. The answer is OC, "Yes, because all 4 requirements are satisfied."

The triangular prism has 3 cylindrical holes with a diameter of 4 cm. The volume of each hole is approximately 60π cubic centimeters, so the total volume of all three holes is about 180π cubic centimeters.

To find the volume of cylindrical holes in the triangular prism, we need to calculate the volume of one cylinder and then multiply it by three (since there are three cylindrical holes).

Volume of one cylinder = πr²h, where r is the radius of the cylinder and h is the height.

Given the diameter of the cylindrical hole is 4 cm, we can find the radius by dividing it by 2

radius (r) = 4 cm ÷ 2 = 2 cm

The height of the cylinder is the same as the length of the prism, which is 15 cm.

Volume of one cylinder = π(2 cm)² × 15 cm

= 60π cm³

Since there are three cylindrical holes, the total volume of the holes is

Total volume of cylindrical holes = 3 × 60π cm³

= 180π cm³

Therefore, the volume of the three cylindrical holes is 180π cubic centimeters.
