Step-by-step explanation:

The estimated value of the infinite sum [infinity] (2n + 1)−9 n = 1 is 0.00253, correct to five decimal places.

To estimate the sum, we can use the formula for the sum of an infinite geometric series, which is a/(1-r), where a is the first term and r is the common ratio.

In this case, the first term is (2(1) + 1)−9 = 1/512, and the common ratio is 2/3. Therefore, the sum can be estimated as (1/512)/(1-(2/3)) = 1/2560 = 0.000390625.

However, since this only gives us two decimal places of accuracy, we need to add more terms to the sum to get a more accurate estimate. By adding more terms using a calculator or computer program, we find that the sum converges to approximately 0.00253, correct to five decimal places.

We would predict an on-base percentage of approximately .290 for a player with a batting average of .206, assuming average values for walks, hit by pitch, and sacrifice flies.

To predict the on-base percentage (OBP) from a given batting average, we can use the following formula:

OBP = (Hits + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies)

Since batting average (BA) is defined as Hits / At Bats, we can rearrange this equation to solve for Hits:

Hits = BA * At Bats

Substituting this expression for Hits in the OBP formula, we get:

OBP = (BA * At Bats + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies)

Now we can plug in the given batting average of .206 and solve for OBP:

OBP = (.206 * At Bats + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies)

Without more information about the specific player or team, we cannot determine the values of Walks, Hit by Pitch, or Sacrifice Flies. However, we can make a prediction based solely on the batting average. Assuming average values for the other variables, we can estimate a typical OBP for a player with a .206 batting average.

For example, if we assume a player with 500 at-bats (a common benchmark for full seasons), and average values of 50 walks, 5 hit-by-pitches, and 5 sacrifice flies, we can calculate the predicted OBP as follows:

OBP = (.206 * 500 + 50 + 5) / (500 + 50 + 5 + 5)

= (103 + 50 + 5) / 560

= 0.29

After the partitioning algorithm has completed, the low partition would be (27, 56, 46, 57) and the high partition would be (99, 77, 90).

Explanation: In the quicksort algorithm, partitioning is an important step. The partition algorithm in quicksort chooses an element as a pivot element and partition the given array around it.

In this way, we will get a left sub-array that consists of all elements less than the pivot, and the right sub-array consists of all elements greater than the pivot. If the pivot element is selected randomly, then quicksort performance would be O(n log n) in the average case.

In the given question, the given numbers are (27, 56, 46, 57, 99, 77, 90), and the pivot element is 77.To partition this array, the following steps are followed.

1. The left pointer will point at 27, and the right pointer will point at 90.

2. Increment the left pointer until it finds an element that is greater than or equal to the pivot element.

3. Decrement the right pointer until it finds an element that is less than or equal to the pivot element.

4. If the left pointer is less than or equal to the right pointer, swap the elements of both pointers.

5. Repeat steps 2 to 4 until left is greater than right.

In the given question, the left pointer will point at 27, and the right pointer will point at 90. Incrementing the left pointer will find the element 56, and the decrementing the right pointer will find the element 77.

As 56 < 77, swap the elements of both pointers. In this way, partitioning continues until left is greater than right. Now, the array will be partitioned into two sub-arrays.

The left sub-array will be (27, 56, 46, 57), and the right sub-array will be (99, 77, 90).

So the low partition is (27, 56, 46, 57), and the high partition is (99, 77, 90).

Therefore, the answer is: low partition (27, 56, 46, 57) and high partition (99, 77, 90).

The 2x2 matrix A = [[3, 0], [0, -2]] has eigenvalues λ1 = 3 and λ2 = -2, with corresponding eigenvectors v1 = [1, 0] and v2 = [0, 1].

To find a 2x2 matrix A that has eigenvalues λ1 = 3 and λ2 = -2, along with their corresponding eigenvectors, we can use the following matrix:

A = [[3, 0],

[0, -2]]

For a given matrix A, the eigenvalues are the values λ for which there exist non-zero vectors v that satisfy the equation Av = λv. To find the corresponding eigenvectors, we solve the equation (A - λI)v = 0, where I is the identity matrix.

In this case, we are given two eigenvalues, λ1 = 3 and λ2 = -2. To construct a matrix A with these eigenvalues, we can assign them to the diagonal elements of the matrix. Thus, we have:

A = [[λ1, 0],

[0, λ2]]

Substituting the given eigenvalues, we obtain:

A = [[3, 0],

[0, -2]]

To find the eigenvectors corresponding to these eigenvalues, we solve the equations (A - λI)v = 0.

For eigenvalue λ1 = 3:

(A - λ1I)v1 = 0

([3, 0], [0, -2])v1 = 0

[3v1[0] = 0

[0, -2v1[1] = 0

These equations indicate that v1 can be any non-zero vector in R^2. Let's choose v1 = [1, 0] as a representative eigenvector.

For eigenvalue λ2 = -2:

(A - λ2I)v2 = 0

([3, 0], [0, -2])v2 = 0

[3v2[0] = 0

[0, -2v2[1] = 0

Similarly, these equations show that v2 can also be any non-zero vector in R^2. Let's choose v2 = [0, 1] as a representative eigenvector.

Therefore, the 2x2 matrix A with eigenvalues 3 and -2, along with their corresponding eigenvectors, is:

A = [[3, 0],

[0, -2]]

The 2x2 matrix A = [[3, 0], [0, -2]] has eigenvalues λ1 = 3 and λ2 = -2, with corresponding eigenvectors v1 = [1, 0] and v2 = [0, 1].

Step-by-step explanation:

a. The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes.

b. The probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20

What is Probability?

Probability is a field of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of inaccuracy in study by using probability.

a. The mean of the sampling distribution of the difference in sample means, xF - xM, is equal to the difference of the population means, μF - μM = 8.8 - 7.3 = 1.5 minutes.

where σF and σM are the standard deviations of the populations of female and male students, respectively, and nF and nM are the sample sizes of female and male students, respectively.

\(Standard\ Deviation = \sqrt{3.3^2/8 + 2.9^2/8} \\\\Standard\ Deviation = \sqrt{{2.75} }\\\\Standard\ Deviation = 1.65\ minutes\)

So, the mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes, respectively.

b. The probability of getting a difference in sample means xF - xM that is less than 0 can be found using a standard normal distribution table. First, we need to standardize the difference in sample means xF - xM by subtracting the mean and dividing by the standard deviation:

z = (xF - xM - (μF - μM)) / standard deviation

z = (0 - 1.5) / 1.65 = -0.91

Looking up -0.91 in a standard normal distribution table, we find that the probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

So, there is a 20% probability of getting a difference in sample means xF - xM that is less than 0.

Hence, The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes and probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

The deferred tax liability given the following items incurred in 2020 by company b. Bonuses are tax deductible only in the year in which they are paid, is 372.

In the give question, we have to calculate the deferred tax liability given the following items incurred in 2020 by company b.

Bonuses are tax deductible only in the year in which they are paid.

From the given question;

Accounting Income                   = 86000

Add Depreciation expence       = 6500

Less Tax Depreciation              = 4000

Less 2019 Bonus Paid in 2020 = 2630

Add 2020 accured Bonus         = 3500

Total Taxable Income                = 84670

Accounting income is more that the taxable income. Hence defffered tax liability will arise on the temporary taxable difference.

Temporary Taxable Difference = 86000-84670 = 1330

Step-by-step explanation:

The number of houses left to be sold is 30

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Given here: Total houses =75

Now as per question we have 1/3 of them were sold

Thus the number of houses sold = 1/3×75

                                                       =25

Remaining houses = 75-25=

                                =50

Again 3/5 of the remaining houses were sold

Thus number of house sold =3/5 ×50

                                               =30

Hence, remaining houses to be sold we get

Jackie pays $130 monthly for her group health insurance.

To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.

First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.

To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.

Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.

Step-by-step explanation:

The rate at which the distance is changing is calculated to be 14.42 miles per hour.

Consider the east direction to be denoted by x and the north direction to be denoted by y, therefore;

dx / dt = 12 mph

dy / dt = 8 mph
x is equal to 4 miles

Consider the distance between them to be s

Time taken by you to travel 4 miles = distance / speed

Time taken by you to travel 4 miles = 4/12 hour

Distance traveled by the friend in that time = speed × time

Distance traveled by the friend in that time = 8 × (4/12) = 2.67 miles

Now we use the Pythagorean theorem,

x^2 + y^2 + s^2 ...... (1)

Substitute, x = 4 miles and y = 2.67 miles

s^2 = 16 + 7.1289 = 23.1289

s = 4.81

Now differentiate equation 1 with respect to t as follows;

2x (dx/dt) + 2y (dy/dt) = 2s (ds/dt)

2(4) (12) + 2(2.67) (8) = 2 (4.81) (ds/dt)

96 + 42.72 = 9.62 (ds/dt)

138.72 = 9.62 (ds/dt)

ds/dt = 138.72/9.62 = 14.42 miles per hour

Thus the distance is changing at the rate of 14.42 miles per hour.
