For a taxable income of $1,80,900, the effective tax rate is 21.11%.

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

The simplified result of the multiplication is\(6x^3 - 8x^2 + 5x.\)

To multiply the expressions\(2x(x^2 + 5)\)and\(2x^3 - 10x^2 + 2x^2 - 10x + 2x^2 + 10x + 2x^3 - 5x,\) we can simplify and combine like terms:

First, let's multiply 2x by each term in the expression:

\(2x(x^2 + 5):\\2x * x^2 = 2x^3\\2x * 5 = 10x\)

So, the first part of the result is: 2x^3 + 10x.

Next, let's combine like terms in the expression:\(2x^3 - 10x^2 + 2x^2 - 10x + 2x^2 + 10x + 2x^3 - 5x:\\(2x^3 + 2x^3) + (-10x^2 + 2x^2) + (-10x + 10x) + (-5x) = 4x^3 - 8x^2 - 5x.\)

Finally, we can add the two parts together to get the final result:

\(2x(x^2 + 5) * (2x^3 - 10x^2 + 2x^2 - 10x + 2x^2 + 10x + 2x^3 - 5x) = (2x^3 + 10x) + (4x^3 - 8x^2 - 5x) = 6x^3 - 8x^2 + 5x.\)

Therefore, the simplified result of the multiplication is\(6x^3 - 8x^2 + 5x.\)

The probability that at most 4 customers arrive within a 5-minute period is approximately 0.128 and the probability that the service time will be less than or equal to 30 seconds is 0.5276.

Given that during lunchtime, customers arrive at a postal office at a rate of 36 per hour. The interarrival time of the arrival process can be approximated with an exponential distribution. Customers can be served by the postal office at a rate of 45 per hour. The system has a single server. The service time for the customers can also be approximated with an exponential distribution.

We need to calculate the probability that at most 4 customers arrive within a 5-minute period.

We know that,

λ = 36 customers per hour

So, μ = 36 customers per 60 minutes

= 0.6 customers per minute

P(X ≤ 4) = P(0) + P(1) + P(2) + P(3) + P(4)

= e^-λ + λe^-λ + (λ^2 / 2)e^-λ + (λ^3 / 6)e^-λ + (λ^4 / 24)e^-λ

= e^-36 (1 + 36 + (36^2 / 2) + (36^3 / 6) + (36^4 / 24))≈ 0.128

We need to calculate the probability that the service time will be less than or equal to 30 seconds.

We know that,

μ = 45 customers per hour

= 0.75 customers per minute

P(T ≤ 30 seconds) = P(T ≤ 0.5 minutes)

= 1 - e^-μT

= service time

= 30 seconds

= 0.5 minutes

∴ P(T ≤ 0.5)

= 1 - e^-0.75

= 1 - 0.4724

= 0.5276

Hence, the probability that at most 4 customers arrive within a 5-minute period is approximately 0.128 and the probability that the service time will be less than or equal to 30 seconds is 0.5276.

To find the inverse function of F(x) = 2x - 3, we replace F(x) with y, swap the positions of x and y, and solve for y. The inverse function is f⁻¹(x) = (x+3)/2.

To find the inverse function of F(x) = 2x - 3, follow these steps

Replace F(x) with y. The equation now becomes y = 2x - 3.

Switch the positions of x and y, so the equation becomes x = 2y - 3.

Solve for y in terms of x. Add 3 to both sides: x + 3 = 2y.

Divide both sides by 2 (x + 3)/2 = y.

Replace y with the notation for the inverse function, f⁻¹(x): f⁻¹(x) = (x + 3)/2.

So, the inverse function of F(x) = 2x - 3 is f⁻¹(x) = (x + 3)/2.

The inequality that can be used to determine how many CDs Karen can order is 12x + 4 ≤ 60.

To determine how many CDs Karen can order, we need to consider the cost per CD and the flat shipping rate.

Let's break down the information given.

The cost per CD is $12, and the flat shipping rate is $4.

If Karen orders x number of CDs, the total cost of the CDs (before shipping) would be 12x dollars.

In addition to the cost of the CDs, Karen needs to pay the flat shipping rate of $4.

Therefore, the total amount Karen needs to spend, including shipping, is 12x + 4 dollars.

We are told that Karen has $60 that she can spend on CDs.

This means that the total amount she spends, including shipping, should be less than or equal to $60.

Therefore, the correct inequality to determine how many CDs Karen can order is:

12x + 4 ≤ 60

This inequality ensures that the total amount spent on CDs, including shipping, does not exceed $60.

If we solve this inequality for x, we can find the maximum number of CDs Karen can order within her budget.

Hence, the answer is option D. 12x + 4 ≤ 60.

The rate at which the volume of the sphere is changing is approximately \(\(0.16\pi\)\) cubic inches per second.

Given:

- \(\(\frac{dA}{dt} = 5\)\) square inches per second (rate of change of surface area)

- \(\(\frac{dr}{dt} = 0.2\)\) inches per second (rate of change of radius)

We want to find the rate at which the volume of the sphere \((\(\frac{dV}{dt}\))\) is changing.

We know the formulas for the volume \((\(V\))\) and surface area \((\(A\))\) of a sphere in terms of its radius \((\(r\))\):

\(\(V = \frac{4}{3}\pi r^3\)\)

\(\(A = 4\pi r^2\)\)

To find \(\(\frac{dV}{dt}\)\), we differentiate the volume formula with respect to time \((\(t\))\):

\(\(\frac{dV}{dt} = \frac{d}{dt} \left(\frac{4}{3}\pi r^3\)\)\)

Using the chain rule, we have:

\(\(\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}\)\)

Now, we can substitute the given values:

\(\(\frac{dV}{dt} = 4\pi (0.2)^2\)\)

Simplifying this expression:

\(\(\frac{dV}{dt} = 0.16\pi\)\) cubic inches per second

Therefore, the rate at which the volume of the sphere is changing is approximately \(\(0.16\pi\)\) cubic inches per second.

The monthly payment needed to accumulate $1.0 million in 40 years with a 12% compounded monthly interest rate is approximately $137.95.

To determine the monthly payment needed to accumulate $1.0 million in 40 years with a 12% compounded monthly interest rate, we can use the future value of an ordinary annuity formula:

FV = P * [(1 + r)^n - 1] / r

Where:

FV = Future value ($1.0 million)

P = Monthly payment

r = Monthly interest rate (12% divided by 12)

n = Number of compounding periods (40 years multiplied by 12)

Substituting the values into the formula:

$1,000,000 = P * [(1 + 0.12/12)^(40*12) - 1] / (0.12/12)

Simplifying the equation:

1,000,000 = P * (1.01^480 - 1) / 0.01

1,000,000 = P * (7.244) / 0.01

P = 1,000,000 * 0.01 / 7.244

P ≈ $137.95

Therefore, the monthly payment needed to accumulate $1.0 million in 40 years with a 12% compounded monthly interest rate is approximately $137.95.

Given data values are 55, 56, 70, 61, 53, 57, 50, 73, 52, 69, and 2. We need to calculate the mean, median, and mode of this sample.So, let's first arrange the data values in ascending order:2, 50, 52, 53, 55, 56, 57, 61, 69, 70, 73

Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:

Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11

Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.

Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).

Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.

Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.

Therefore, the mode of the given data values is N/A (not applicable).Hence, the mean, median, and mode of the given data values are:Mean = 54.36Median = 55.5Mode = N/A (not applicable)

Set A is finite because it consists of positive integers greater than 50 but less than 250. This implies that there is a finite number of elements in the set, as the range of values is limited. A set is considered finite when it has a specific and countable number of elements. In this case, set A has a well-defined starting point (51) and an ending point (249), allowing us to determine its cardinality. Therefore, the set A is finite.

In summary, the given set A, which consists of positive integers greater than 50 but less than 250, is finite. This is because it has a limited range of values and a well-defined starting and ending point, allowing us to count its elements. To delve deeper into the concepts of finite and infinite sets, one can explore the set theory, which deals with the properties and relationships between sets.
