Answer: 96

Given statement solution is :- The new cost of a table is:

New cost of a table = T + (T * 20%)

New cost of a table = T + (T * 0.2)

New cost of a table = 1.2T

The new cost of a chair is:

A new chair would cost $900 plus ($900 * 20%)

A chair would cost $900 new plus ($900 * 0.2)

A new chair would cost $900 plus $180.

New cost of a chair = $1,080

Let's assume that a chair originally cost C and a table originally cost T.

The price of two chairs, based on the information provided, is $1,800. So we can set up the following equation:

2C = $1,800

When we multiply the two sides of the equation by 2, we get:

C = $1,800 / 2

C = $900

This indicates that a chair once cost $900.

After a month, the price of every chair and every table has now gone up by 20%. This means the new cost of a chair is 120% of the original cost, and the new cost of a table is also 120% of the original cost.

The new cost of a chair is:

A new chair would cost $900 plus ($900 * 20%)

A chair would cost $900 new plus ($900 * 0.2)

A new chair would cost $900 plus $180.

New cost of a chair = $1,080

Similarly, the new cost of a table is:

New cost of a table = T + (T * 20%)

New cost of a table = T + (T * 0.2)

New cost of a table = 1.2T

According to the given information, the office bought 6 chairs and 2 tables at $4,800. Using the updated costs, we can construct the following equation:

(6 * $1,080) + (2 * 1.2T) = $4,800

Simplifying the equation, we have:

6,480 + 2.4T = 4,800

Subtracting 2.4T from both sides, we get:

6,480 = 4,800 - 2.4T

Subtracting 4,800 from both sides, we have:

1,680 = -2.4T

Dividing both sides by -2.4, we find:

T = 1,680 / -2.4

T ≈ -$700

The expressions (7x - 6y) and (3x - 5y) added together result in 10x - 11y.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Consider your square as being composed of smaller unit squares.

The number of unit squares necessary to completely cover the surface area of a specific 2-D shape is used to calculate the area of a figure. Some typical units for measuring area are square cms, square feet, square inches, square meters, etc.

Draw unit squares with 1-centimeter sides in order to calculate the area of the square figures shown below. The shape will therefore be measured.

According to our question-

(7x – 6y) and (3x – 5y

Then the sum of the expressions will be

(7x – 6y) + (3x – 5y)

7x – 6y + 3x – 5y

10x – 11y

Hence, The expressions (7x - 6y) and (3x - 5y) added together result in 10x - 11y.

a)The distribution of \(X_{1} +X_{2}+X_{3}\) is a normal distribution with mean μ = 180 and variance σ² = 36.(b)P( \(X_{1} +X_{2}+X_{3}\) > 185) ≈ P(Z > 5/6).(c) The distribution of Y - X is a normal distribution with mean μ = 5 and variance σ² = 27.(d)P(Y - X > 8) ≈ P(Z > 1.732)

(a) The sum of independent normal random variables follows a normal distribution. In this case, X1, X2, and X3 are independent normal random variables with a common mean μ1 = 60 and a common variance σ1² = 12. Therefore, the distribution of \(X_{1} +X_{2}+X_{3}\) is also a normal distribution with the following parameters:

Mean: μ = μ1 + μ1 + μ1 = 60 + 60 + 60 = 180

Variance: σ² = σ1² + σ1² + σ1² = 12 + 12 + 12 = 36

So, the distribution of \(X_{1} +X_{2}+X_{3}\) is a normal distribution with mean μ = 180 and variance σ² = 36.

(b) To find P(\(X_{1} +X_{2}+X_{3}\) > 185), we need to calculate the probability that the sum of X1, X2, and X3 exceeds 185. Since X1, X2, and X3 are normally distributed with a mean of 180 and a variance of 36, we can standardize the variable using the Z-score formula.

Z = (X - μ) / σ

Z = (185 - 180) / √36 = 5 / 6

Now, we need to find the probability that Z is greater than 5/6. We can look up this probability in the standard normal distribution table or use statistical software to find the corresponding value.

P(\(X_{1} +X_{2}+X_{3}\) > 185) ≈ P(Z > 5/6)

(c) The difference of independent normal random variables follows a normal distribution. In this case, Y - X is the difference between Y (with mean μ2 = 65 and variance σ2² = 15) and X (with mean μ1 = 60 and variance σ1² = 12).

The mean of Y - X is μ2 - μ1 = 65 - 60 = 5.

The variance of Y - X is σ2² + σ1² = 15 + 12 = 27.

Therefore, the distribution of Y - X is a normal distribution with mean μ = 5 and variance σ² = 27.

(d) To find P(Y - X > 8), we need to calculate the probability that the difference between Y and X exceeds 8. Since Y - X is normally distributed with a mean of 5 and a variance of 27, we can standardize the variable using the Z-score formula.

Z = (Y - X - μ) / σ

Z = (8 - 5) / √27 ≈ 1.732

Now, we need to find the probability that Z is greater than 1.732. We can look up this probability in the standard normal distribution table or use statistical software to find the corresponding value.

P(Y - X > 8) ≈ P(Z > 1.732)

The taxable income of Shawrya Singh for the year ending 30 June 201X is $18,871.43, and the tax liability is $6,039.98.

Calculation of Shawrya Singh's taxable income and tax liability for the year ending 30 June 201X:

The following distributions were received by Shawrya Singh during the year 201W/1X:01/10/201W: 70%

franked distribution from CSL: $2,000

Franking Credit = 2,000 * 0.7 = $1,400

Grossed-up dividend = $2,000 + $1,400 = $3,40001/03/201X: 60%

franked distribution from BHP: $4,000 13/04/201X

Credit = 4,000 * 0.6 = $2,400

Grossed-up dividend = $4,000 + $2,400 = $6,400

13/04/201X: Fully franked distribution from NAB: $3,200

Franking Credit = 3,200

Grossed-up dividend = $3,200 / (1 - 0.3) = $4,571.43* 15/06/201X: Unfranked distribution from ANZ: $4,500

Grossed-up dividend = $4,500 / (1 - 0) = $4,500

Total Grossed-up Dividend = $3,400 + $6,400 + $4,571.43 + $4,500 = $18,871.43*

The franking rate is assumed to be 30% because Shawrya is not a base rate entity. Deducting the Deductions: No deductions are allowable; thus, the taxable income is equivalent to the grossed-up dividend of $18,871.43.

Tax Payable = $18,871.43 * 0.32 = $6,039.98 (Marginal tax rate is 32%)

Therefore, the taxable income of Shawrya Singh for the year ending 30 June 201X is $18,871.43, and the tax liability is $6,039.98. Relevant legislation to support the answer is available in the Income Tax Assessment Act 1997.

Answer:

Step-by-step explanation:

As n → ∞

\(\frac{85}{n}\) , \(\frac{75}{2n}\) , \(\frac{15}{2n^2}\) → 0

(a) The z-score for an age of 30 years is approximately 0.6857.

(b) The winner's age of 30 years is roughly 0.6857 standard deviations above the mean age of the winners (27.6 years), indicating they were slightly older than the average age.

(a) To transform the age of 30 years to a z-score, we use the formula:

z = (x - μ) / σ

where:

x = individual value (age of the winner) = 30 years

μ = mean age = 27.6 years

σ = standard deviation = 3.5 years

Plugging in the values, we get:

z = (30 - 27.6) / 3.5

Calculating this expression, we find:

z ≈ 0.6857

Therefore, the z-score for an age of 30 years is approximately 0.6857.

(b) Interpretation of the results:

The z-score indicates the number of standard deviations an individual value (in this case, the age of the winner) deviates from the mean. A positive z-score suggests that the individual value is above the mean.

In this context, the z-score of approximately 0.6857 means that the age of the winner (30 years) is roughly 0.6857 standard deviations above the mean age of the winners (27.6 years). This suggests that the winner in that recent year was slightly older than the average age of the tournament winners.

By using z-scores, we can compare and interpret individual values within the context of a distribution, such as the bell-shaped distribution of ages in the cycling tournament winners.

Answer:

Step-by-step explanation:

The degree 4 Taylor polynomial for f(x) = x sin(x) at a = 0 is: T4(x) = x²/2 − x⁴/24 and the maximum error is approximately 0.002.

a) Approximate f(x) = x sin x by a Taylor polynomial with degree 4 at the number a = 0. In order to find the degree 4 Taylor polynomial for f(x) = x sin(x) at a = 0, we need to find its derivatives up to the fourth degree. Here are the first five derivatives:

f(x) = x sin(x)f'(x) = sin(x) + x cos(x)

f''(x) = 2 cos(x) − x sin(x)

f'''(x) = −3 sin(x) − x cos(x)

f''''(x) = −4 cos(x) + x sin(x)

Now, we evaluate each derivative at x = 0:

f(0) = 0

f'(0) = sin(0) + 0 cos(0) = 0

f''(0) = 2 cos(0) − 0 sin(0) = 2

f'''(0) = −3 sin(0) − 0 cos(0) = 0

f''''(0) = −4 cos(0) + 0 sin(0) = −4

Therefore, the degree 4 Taylor polynomial for f(x) = x sin(x) at a = 0 is:T4(x) = f(0) + f'(0)x + (f''(0)/2!) x² + (f'''(0)/3!) x³ + (f''''(0)/4!) x⁴T4(x) = 0 + 0x + 2/2! x² + 0x³ − 4/4! x⁴T4(x) = x²/2 − x⁴/24

Therefore, the degree 4 Taylor polynomial for f(x) = x sin(x) at a = 0 is: T4(x) = x²/2 − x⁴/24

b) Use Taylor's Inequality to estimate the accuracy of the approximation f(x)≈T4​(x) when x lies in the interval −1≤x≤1. Taylor's Inequality states that the error between the actual value of a function and its Taylor polynomial approximation can be bounded by the following formula: |f(x) − Tn(x)| ≤ M(x − a)^{n+1}/(n+1)!

where M is an upper bound for |f^{(n+1)}(t)| for some t between a and x.

In our case, n = 4, a = 0, and we want to estimate the error for −1 ≤ x ≤ 1. Thus, we need to find an upper bound for |f^{(5)}(t)| for some t between 0 and 1. The fifth derivative of f(x) = x sin(x) is:  f^{(5)}(x) = −5 cos(x) + x sin(x)

Thus, an upper bound for |f^{(5)}(t)| when −1 ≤ t ≤ 1 is 6. Therefore, the error between f(x) and T4(x) is bounded by: |f(x) − T4(x)| ≤ 6|x|⁵/5!when −1 ≤ x ≤ 1. Plugging in x = 1, we get: |f(1) − T4(1)| ≤ 6/5!

X and Y are not independent.

P(Y > 2X) = 3/16.

Marginal pdf of X = 12x(1-x)² for 0 < x < 1

(a) To determine if X and Y are independent, we need to check if the joint pdf can be factored into the product of the marginal pdfs:

f(x,y) = 24xy if 0 < x, 0 < y, x + y < 1, and zero otherwise.

Marginal pdf of X can be calculated by integrating the joint pdf over the all possible values of y:

f(x) = ∫ f(x,y) dy from 0 to 1-x

= ∫ 24xy dy from 0 to 1-x

= 12x(1-x)² for 0 < x < 1

Similarly, the marginal pdf of Y can be found by integrating the joint pdf over all possible values of x:

f(y) = ∫ f(x,y) dx from 0 to 1-y

= ∫ 24xy dx from 0 to 1-y

= 12y(1-y)² for 0 < y < 1

To check for independence, we need to verify if f(x,y) = f(x)f(y) for all x and y. However, if we multiply the marginal pdfs, we get:

f(x)f(y) = 144xy(1-x)²(1-y)² for 0 < x < 1 and 0 < y < 1

This is not the same as the joint pdf, so X and Y are not independent.

(b) To find P(Y > 2X), we need to integrate the joint pdf over the region where Y > 2X:

P(Y > 2X) = ∫∫ f(x,y) dA over the region where Y > 2X

= ∫∫ 24xy dA over the region where Y > 2X

= ∫∫ 24xy dxdy over the region where 0 < y < 2x and x+y < 1

Answer:

The measure of ∠A'B'C' is 125°

Step-by-step explanation:

The given information are;

The measure of ∠ABC = 125°

The transformation applied to ∠ABC = 75° rotation about point B

The vertices of the image formed after rotation = ∠A'B'C'

Therefore, given that a rotational transformation is a form of rigid transformation, we have that the size and shape of the figure in the preimage = The size and shape of the figure of the image

Therefore, the measure of m∠ABC = The measure of m∠A'B'C'.

The measure of the angle  A'B'C' which is created by rotating angle ABC 75° about point B is 125 degrees.

Rotation of a figure is the transformation of it about a point in either clockwise or anticlockwise direction. By rotating, a figure changes the coordinate point of the figure.

The following information regarded to angle ABC are given.

The rotation of 75 degree is applied on the given angle ABC from the point B. This will change the coordinate points of the point A and point C.

As it is known that the rotation changes the coordinate point and the position of the shape but does not change the shape and size of the original figure.

Hence, the measure of the angle  A'B'C' which is created by rotating angle ABC 75° about point B is 125 degrees.
