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 magnitude of the fourth displacement is 230 m, and the direction is 45° east of south.

To determine the magnitude and direction of the fourth displacement, we can add up the individual displacements and analyze the resultant displacement.

Given:

First displacement: 190 m west

Second displacement: 230 m at 45° east of south

Third displacement: 270 m at 30° east of north

Let's analyze the displacements one by one:

1. The first displacement is 190 m straight west. Since it is a straight line in one direction, we only consider its magnitude and direction. The magnitude is 190 m, and the direction is due west.

2. The second displacement is 230 m at 45° east of south. To determine the components of this displacement, we can break it into its north-south and east-west components. The east-west component is given by 230 m * cos(45°), which is approximately 162.43 m, and the north-south component is given by 230 m * sin(45°), which is also approximately 162.43 m.

3. The third displacement is 270 m at 30° east of north. Similar to the second displacement, we can determine its components. The east-west component is 270 m * cos(30°), which is approximately 233.45 m, and the north-south component is 270 m * sin(30°), which is approximately 135 m.

Now, we can add up the east-west and north-south components separately:

East-West component: 162.43 m - 233.45 m = -71.02 m

North-South component: 162.43 m + 135 m = 297.43 m

To find the magnitude of the fourth displacement, we use the Pythagorean theorem:

Magnitude of the fourth displacement = sqrt((-71.02 m)^2 + (297.43 m)^2) ≈ 230 m

The magnitude of the fourth displacement is approximately 230 m.

To find the direction of the fourth displacement, we can use the inverse tangent function:

Direction of the fourth displacement = atan((-71.02 m) / (297.43 m)) ≈ -14.67°

However, since the question asks for the direction in degrees, we need to add 180° to the result to obtain the direction relative to the positive x-axis. Therefore, the direction of the fourth displacement is approximately 180° - 14.67° = 165.33°.

Hence, the magnitude of the fourth displacement is 230 m, and the direction is approximately 165.33° east of south.

Answer:

Step-by-step explanation:

The probability of getting a difference of 3 when two fair dice are thrown together is 1/9.

Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain. Probability can also be expressed as a percentage or fraction. Probability is used to describe the likelihood of an event occurring, and its calculation is based on the number of possible outcomes of the event.

This is due to the fact that there are 6 possible outcomes for each dice, and 36 possible outcomes when both dice are thrown. The only way to get a difference of 3 is for the first dice to show a 4 (1/6 probability) and the second dice to show a 1 (also 1/6 probability). This gives a combined probability of 1/6 x 1/6 = 1/36, which is 1/9.

Answer:

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.

Step-by-step explanation:

Given that:

An airplane travels 5040 kilometers in 6 hours against the wind

An airplane travels 6000 kilometers in 5 hours with the wind

Let,

x be the speed of plane in still air

y be the rate of wind

Combined speed against the wind = x - y

Combined speed with the wind = x+y

Speed = \(\frac{Distance}{Time}\)

x-y= \(\frac{5040}{6} = 840\)

x - y = 840    Eqn 1

x + y = \(\frac{6000}{5} = 1200\)    Eqn 2

Adding Eqn 1 and 2

x+y+x-y=1200+840

2x=2040

Dividing both sides by 2

\(\frac{2x}{2}=\frac{2040}{x}\\x=1020\)

Putting x=1020 in Eqn 2

1020+y=1200

y=1200-1020

y=180

Hence,

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.

The probability that all the answers are False is (1/2)²

To find the probability that all the answers are "False," assuming the outcomes to be equally likely, follow these steps:

Step 1: Determine the total number of possible outcomes for each question. Since there are only two outcomes, "True" or "False," there are 2 possible outcomes for each question.

Step 2: Identify the favorable outcome for each question. In this case, the favorable outcome is "False."

Step 3: Calculate the probability of getting a "False" answer for a single question. Since the outcomes are equally likely, the probability is 1/2 (1 favorable outcome out of 2 possible outcomes).

Step 4: Determine the total number of questions. Let's assume there are 'n' questions.

Step 5: Calculate the probability of getting all "False" answers. Since the questions are independent, multiply the probability of getting a "False" answer for a single question (1/2) by itself 'n' times.

Step-by-step explanation:

The probability that a load of aggregates found to be substandard is from Company a is approximately 0.818 or 81.8%.

To solve this problem, let's define the events and calculate the probabilities step by step:

Events:

A = Aggregates supplied by Company a

B = Aggregates supplied by Company b

E = Aggregates are substandard

Probabilities:

prob{A} = Probability of aggregates supplied by Company a = 600 truck-loads / (600 truck-loads + 400 truck-loads) = 0.6

prob{B} = Probability of aggregates supplied by Company b = 400 truck-loads / (600 truck-loads + 400 truck-loads) = 0.4

Given that 3% of the material from Company a is substandard and 1% of the material from Company b is substandard, we can calculate the probability of substandard aggregates.

prob{E|A} = Probability of substandard aggregates given they are supplied by Company a = 3% = 0.03

prob{E|B} = Probability of substandard aggregates given they are supplied by Company b = 1% = 0.01

To calculate the overall probability of substandard aggregates (prob{E}), we can use the Law of Total Probability:

prob{E} = prob{E|A} * prob{A} + prob{E|B} * prob{B}

Substituting the values we have:

prob{E} = (0.03 * 0.6) + (0.01 * 0.4)

= 0.018 + 0.004

= 0.022

Finally, to find the probability that a load of aggregates found to be substandard is from Company a (prob{A|E}), we can use Bayes' Theorem:

prob{A|E} = (prob{E|A} * prob{A}) / prob{E}

Substituting the values we have:

prob{A|E} = (0.03 * 0.6) / 0.022

= 0.018 / 0.022

≈ 0.818

Therefore, the probability that a load of aggregates found to be substandard is from Company a is approximately 0.818 or 81.8%.

The smallest value of n for which the nth term of the geometric sequence with first term 3/4 and second term 15 is divisible by one .

We want to find the smallest value of n for which the nth term of the sequence is divisible by one million. In other words, we want to find the smallest value of n such that 10^6 divides the nth term of the sequence. We can rewrite this condition as (3/4)(20)^(n-1) = k*10^6, where k is an integer. Dividing both sides by 10^6 and simplifying, we get (3/4)(2/5)^(n-1) = k/125. We want to find the smallest value of n such that k/125 is an integer. Since 3 and 125 are relatively prime, k must be a multiple of 125 for k/125 to be an integer.

Therefore, we can write k = 125m, where m is an integer. Substituting this into the previous equation and simplifying, we get (2/5)^(n-1) = (4/15)m. Taking the logarithm of both sides, we get (n-1)log(2/5) = log(4/15) + log(m). Since log(2/5) is negative, we can divide both sides by log(2/5) and change the direction of the inequality to get n-1 >= (-1/log(2/5))(log(4/15) + log(m)).

Therefore, the smallest value of n for which the nth term of the sequence is divisible by one million is the smallest integer greater than or equal to (-1/log(2/5))(log(4/15) + log(m)) + 1. We want to choose m so that this expression is minimized. Since log(4/15) is negative and log(m) is non-negative, the smallest value of the expression is achieved when log(m) = 0, which corresponds to m = 1. Therefore, the smallest value of n for which the nth term of the sequence is divisible by one million is the smallest integer greater than or equal to (-1/log(2/5))(log(4/15) + log(1)) + 1, which simplifies to 24.

Answer:4.62x10^13

Step-by-step explanation:

Answer:

The equation for the nth term of the arithmetic sequence is:

\(a_{n} = a + (n-1)d\\\)

The \(a_{30}\) is 140

Step-by-step explanation:

"a" represents the first term which is -5.

"d" represents the common difference which is 5.

To find the common difference, just subtract the 2nd and 1st term.

0 - (-5) = 5

Now put the values in the equation:

\(a_{n} = a + (n - 1)d\\a_{n} = (-5) + (n - 1)5\)

We are finding the 30th term so just put 30 to the "n" to help us find the 30th term of the sequence.

\(a_{30} = -5 + (30-1)5\\a_{30} = -5 + (29)5\\a_{30} = -5 + 145\\a_{30} = 140\)

So the 30th term is 140
