Answer:

Step-by-step explanation:

The answer is 22 the reason why is because 5 + 5 + 8 + 4= 22 so you just add all the numbers up!

The sample mean is -2.0, the sample variance is 11.67, and the sample standard deviation is 3.42.

The sample mean is the average of a given set of numbers. To find the sample mean of the set of numbers {-8, -4, -3, 0, 1, 2}, you add up all of the numbers and divide by the number of numbers in the set, which is 6. So, the sample mean is -2.0. The sample variance measures the variability of the data, or how spread out the data is. To calculate the sample variance, you first subtract the mean from each number and square the result of each. Then, you add up all of the squares and divide by the number of numbers in the set. In this case, the sample variance is 11.67. The sample standard deviation is the square root of the sample variance and is a measure of how far on average each number is from the mean. To calculate the sample standard deviation, you simply take the square root of the sample variance, which is 3.42.

Sample mean: -2.0 = (-8 + -4 + -3 + 0 + 1 + 2) / 6

Sample variance: 11.67 = (64 + 16 + 9 + 0 + 1 + 4) / 6

Sample standard deviation: 3.42 = √11.67

The associative property states that the way in which numbers are grouped in an arithmetic expression does not affect the result of the computation. For example, in the expression (a + b) + c, the addition of a + b can be done first, and then added to c, or the addition of b + c can be done first and then added to a. The result will be the same either way.

In the expression you provided, the associative property can be used to group the terms in the following way:

(8/9 / 7/5) x 3/16

= (8/9 x 3/16) / (7/5)

Then, the division and multiplication operations can be carried out in the order that they appear, from left to right:

= (24/144) / (7/5)

= (1/6) / (7/5)

Finally, the division operation can be carried out to obtain the final result:

Answer: This question is most likely assuming a poisson distribution; it is impossible to compute without some distribution clarified, as otherwise we don't have applicable information.

Poison distribution is:

(λke-k) / k!

Where k is the number of outcomes you are looking for, and λ is the accepted average number of outcomes. So, λ is 6 for this example, and we are looking for values of k to use.

Solving problem b is simply substituting the value.

Prob of 5 parts: (65e-5) / 5!, using a calculator and working it out, this approximates to 0.437.

Solving problem a can be used for c; to get a, do the above equation 5 times for k = 0, 1, 2, 3 and 4, and add them all together. Though somewhat tedious, this would lead to the solution. To get part c, you would use the property of complements:

The cumulative probability here would be 1 - (total prob of all scenarios with k = 0, 1, 2, 3, 4, 5). You can get that total probability by adding the answers to part a and b together.

Finally, regarding part d, the above work can be redone with a new formula, now (λke-k) / k! would have λ as 5. This would reduce the answer for a, but increase it for b and c, which you can verify by running the calculations.

If X and Y are independent standard normal random variables, joint density function of u and v is 1/(π+v²).

We have X and Y are independent standard normal random variables. It is given that X and Y are two independent standard normal random variables.

That is, The probability density function of standard normal random variable X and Y as shown below:

f(x) = 1/√2π exp{ -x²/2}

f(y) = 1/√2π exp{ -y²/2}

The joint density function of X and Y is shown as

f(x,y) = 1/2π exp{ -(x² + y²)/2}

It is given that, U = X , V = x/y

=> Y = X/V = U/V

The Jacobean transformation is shown below:

J = | ∂x/∂u ∂x/∂v |

| ∂y/∂u ∂y/∂v |

= det [ 1 0 ; 1/v -u/v²]

= 1 ×(-u/v²) - 0×(1/v)

= -u/v²

The joint density function of u and v is,

f(u,v) = fₓₓ(x,y)|J| =1/2π exp{ -(u² + (u/v)²} u/v²

find the value of f(x/y)

fᵥ (V) = ∫ f(u,v) du where limits u = -∞ to u= ∞

=∫{1/2π exp{ -(u²+ (u/v)²)} u/v²du , u = -∞ to u = ∞

= 2 ∫1/2π exp{ -(u² + (u/v)²)} u/v²du, u = 0 to u = ∞

(since, integrand is even function of u)

Using the change of variable,

u²₁ = u²(1+v²) we have

fᵥ (V) = ∫ 1/(π+v²) exp( -u₁²/2) u/v² du₁, u = 0 to u = ∞

= 1/(π+v²) ∫exp( -u₁²/2) d(u₁/v²) = 1/(π+v²)(1) =1/(π+v²)

Answer:

71/12 = 5 11/12

Step-by-step explanation:

To solve this equation you first have to put the whole number with fraction (mixed number) and convert it into an improper fraction. To do this you have to multiply the whole number by the denominator which is 6 x 2 and you'd get 12 but then you still have the numerator so then you add your answer with the numerator and you'd get 12+1 which is 13. So your improper fraction is 13/2.

Now you set up your equation and you'd subtract. But your denominators are not the same so you have to figure out and find the common denominator. Which is 12. So then for 13/2 you'd multiply both of them by 6 and you'd get 78/12. And the 2nd one you'd multiply it by 1 getting 7/12.

Once you get to this point now you can properly set up the equation and subtract. You'd subtract 78/12 - 7/12 getting 71/12 or if you want it as a mixed number (whole number with fraction) then it is 5 11/12.

f(x, y) = 3x + 2y + C

To know if a vector field is conservative, we have to check if it is the gradient of a scalar function.

The gradient of the function f(x, y) is given by

∇f(x, y) = (∂f/∂x, ∂f/∂y)

If a vector field F(x, y) is the gradient of a scalar function f(x, y), then the following conditions must be satisfied:

F(x, y) = ∇f(x, y)

Whether a given vector field satisfies this condition can be checked by taking the partial derivative with respect to x and y.

∂F/∂x = ∂(6x + 5y)/∂x = 6

∂F/∂y = ∂(5x + 4y)/∂y = 4

The partial derivative of a given vector field is the constant, the gradient of the scalar function. So vector fields are conservative and we can find a potential function f(x, y) such that F(x, y) = ∇f(x, y).

To find the potential function, we can integrate the partial derivative of F(x, y) with respect to x and y.

f(x, y) = ∫∂F/∂xdx + ∫∂F/∂ydy

= ∫6dx + ∫4dy

= 3x + 2y + C

where C is the constant of integration. So the potential function for a given vector field is

f(x, y) = 3x + 2y + C

The probability that state 1 changes to state 2 after three repetitions of the experiment is 0.052.

The first power of the transition matrix A is simply the matrix itself:

A1 = [ 0.3 0.1 0.6 ]

[ 0.5 0.2 0.3 ]

The second power of the transition matrix is obtained by multiplying A by itself:

A2 = A1 * A1 = [ 0.30.3+0.10.5 0.30.1+0.10.2 0.30.6+0.10.3 ]

[ 0.50.3+0.20.5 0.50.1+0.20.2 0.50.6+0.20.3 ]

= [ 0.19 0.06 0.33 ]

[ 0.29 0.08 0.33 ]

The third power of the transition matrix is obtained by multiplying A2 by A:

A3 = A2 * A = [ 0.190.3+0.060.5 0.190.1+0.060.2 0.190.6+0.060.3 ]

[ 0.290.3+0.080.5 0.290.1+0.080.2 0.290.6+0.080.3 ]

= [ 0.161 0.052 0.327 ]

[ 0.247 0.068 0.327 ]

To find the probability that state 1 changes to state 2 after three repetitions of the experiment, we need to look at the second element of the first row of A3. This element is 0.052, so the probability that state 1 changes to state 2 after three repetitions of the experiment is 0.052.
