The annual salary of the man is Rs 780,000 and his total taxes is given by the relation T = Rs 9,000

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Since the man's monthly salary is Rs 65,000, his annual salary would be:

Annual salary = Monthly salary x 12

Annual salary = 65,000 x 12

Annual salary = 780,000

His annual salary of Rs 780,000 falls in the third tax bracket which is from 750,001 to 2,000,000.

So, the tax rate applicable to him would be 30%.

To calculate the amount of tax he would have to pay, we can use the formula:

Tax amount = Tax rate x Taxable income

where taxable income is the income above the lower limit of the tax bracket.

In this case, the taxable income would be:

Taxable income = Annual income - Lower limit of tax bracket

Taxable income = 780,000 - 750,001

Taxable income = 29,999

So, the amount of tax he would have to pay would be:

Tax amount = 30% x 29,999

Tax amount = 8,999.7

Rounding this to the nearest rupee gives us:

Tax amount = Rs 9,000

Hence , the man would have to pay Rs 9,000 in taxes on his annual salary of Rs 780,000.

Answer:

Step-by-step explanation:

The formula for calculating the time it takes to reach a target amount with a constant periodic deposit is given by

Time = ln(Target Amount / (Periodic Deposit x (1 + Interest Rate)^0)) / ln(1 + Interest Rate)

In this case, we have Target Amount = 500,000, Periodic Deposit = 500, and Interest rate = 7.8%. Plugging the values into the formula gives

Time = ln(500,000 / (500 x (1 + 0.078)^0)) / ln(1 + 0.078)

Time = ln(500,000 / 500) / ln(1.078)

Time = ln(1,000) / ln(1.078)

Time = 8.98 years

Rounding to the nearest tenth of a year, the answer is 8.9 years.

The value 2(-7) is interpreted that a location that is twice as far below sea level as the dolphin. Option A is the correct option.

What is the meaning of interpretation?

Elucidate, explain, explicate, and expound are some synonyms for interpret. While all of these words mean "to make something clear or understandable," interpretation adds to explain why dealing with something requires imagination, sympathy, or special knowledge.

Given that sea level is defined as having an elevation of 0. A dolphin is 7 meters below sea level.

If the level is below sea level, then it can represent by a negative number.

The statement "A dolphin is 7 meters below sea level." can be written as:

A dolphin is -7 meters far from sea level.

Thus 2(-7) represents a location that is 7 meters below the dolphin's position.

The factors of a fraction 3 1/2 is 3/2.

Generally, A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another number to generate n. Another name for this concept is a factor of n. One may also state that n is a multiple of m in this particular scenario.

Since 3/2 is a fraction, it does not have any factors since factors are integers that may evenly divide a number. Since 3/2 is a fraction, it does not have any factors. Only integers are capable of having factors; fractions are unable to do so.

To find the factors of a fraction, you can factor the numerator and denominator separately.

In the case of 3 1/2, the numerator 3 is a prime number and cannot be factored further.

However, the denominator 2 can be factored as 2 x 1.

Therefore, the factors of 3 1/2 are: (3 x 1) / (2 x 1),

which can be simplified to 3/2.

According to the given we can state:

Find arc AB, it is a semicircle of 1 cm radius:

ΔAEO and ΔBEO are both isosceles, hence ∠A and ∠B are both 45°.

Find arcs ABD and BAC:

∠AEB is a right angle since ∠AEO and ∠BEO are both 45°.

Hence ∠CED is also right angle as vertical angle with ∠AEB.

Find the length of EC and ED.

We know AD = BC = 2 cm and ΔAEO is 45° right triangle.

It gives us:

Then:

Find arc ECD:

The perimeter is the sum of all the arc measures:

Answer:

[tex]\textsf{Perimeter}=3\pi-\dfrac{\pi}{\sqrt{2}}=7.20333649...\; \sf cm[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $=r \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]

To convert degrees to radians, multiply the angle in degrees by π/180°.

Arc AB

As arc AB has center O, the radius of arc AB is OA = 1 cm.

As AB is a straight line, ∠AOB is 180° = π.

Therefore, the length of arc AB is:

[tex]\implies AB=r \:\theta=1 \cdot \pi = \pi[/tex]

Arc AC

Triangle BOE is a right triangle with base of 1 cm and height of 1 cm.

Therefore, ∠OBE is 45° = π/4

If arc AC has center B, then the radius is AB = 2 cm.

Therefore, the length of arc AC is:

[tex]\implies AC=r \:\theta=2 \cdot \dfrac{\pi}{4} = \dfrac{\pi}{2}[/tex]

Arc BD

Arc BD is the same as arc AC.

[tex]\implies BC= \dfrac{\pi}{2}[/tex]

Arc CD

As triangle BOE is a right triangle with base of 1 cm and height of 1 cm, the length of its hypotenuse BE is:

[tex]\implies BE=\sqrt{1^2+1^2}=\sqrt{2}[/tex]

As arc AC has center B and radius of AB = 2 cm, then BC is also its radius and therefore BC = 2 cm

Therefore:

[tex]\implies CE=BC-BE[/tex]

[tex]\implies CE=2-\sqrt{2}[/tex]

The arc CD has center E so its radius is CE = 2-√2.

As ∠BEO and ∠AEO are both 45° then ∠AEB is 90°.

According to the vertical angle theorem, ∠CED is also 90° = π/2.

Therefore, the length of arc CD is:

[tex]\implies CD=r \:\theta=(2-\sqrt{2}) \cdot \dfrac{\pi}{2} = \dfrac{(2-\sqrt{2})\pi}{2}[/tex]

Perimeter of the egg

The perimeter of the egg is the sum of the found arcs:

[tex]\implies \textsf{Perimeter}=\pi+\dfrac{\pi}{2}+\dfrac{\pi}{2}+\dfrac{(2-\sqrt{2})\pi}{2}[/tex]

[tex]\implies \textsf{Perimeter}=2\pi+\dfrac{(2-\sqrt{2})\pi}{2}[/tex]

[tex]\implies \textsf{Perimeter}=2\pi+\dfrac{2 \pi}{2}-\dfrac{\sqrt{2}\:\pi}{2}[/tex]

[tex]\implies \textsf{Perimeter}=3\pi-\dfrac{\sqrt{2}\:\pi}{2}[/tex]

The p-value, under the assumption that the null hypothesis is true, is the likelihood of obtaining results from a statistical hypothesis test that are at least as extreme as the observed results. The p-value provides the smallest level of significance at which the null hypothesis would be rejected as an alternative to rejection points. The alternative hypothesis is more likely to be supported by stronger evidence when the p-value is lower.

In this case, the survey was done to test the claim that 20% of adult Americans believe that the lottery is the path to riches. The hypothesis test of H0: p=.2 versus Ha: p>.2 resulted in 0.79 for a right-tailed test

Answer:

(g+f)(x/4) = x^2/16 + 3x/4

Step-by-step explanation:

To find (g+f)(x/4), we must first find the expressions for g(x) and f(x) and then add them together.

g(x) = x^2 + 4

f(x) = 3x - 4

So (g+f)(x) = g(x) + f(x) = x^2 + 4 + 3x - 4 = x^2 + 3x + 0

Now we can substitute x/4 for x in the expression:

(g+f)(x/4) = (x/4)^2 + 3(x/4) + 0

Multiplying it out

(g+f)(x/4) = (x^2/16) + (3x/4) + 0

so (g+f)(x/4) = x^2/16 + 3x/4

On October 7, you pay Land Electric $43.90. This is a check transaction and the check number is 400. To record this in your register, you would subtract $43.90 from your current balance, which would bring your new balance to $498.99.

On October 23, you deposit your paycheck. To calculate your paycheck, you would multiply your hourly wage ($7.25) by the number of hours worked (40) by the number of weeks (2). This would give you a gross pay of $1140. Then, you would calculate the deductions: FICA (7.65%), federal withholding (12%), and state withholding (8.75%). To do this, you would multiply your gross pay by the percentage for each deduction and then subtract that amount from the gross pay. Your final paycheck would be $1140 - $87.41 (FICA) - $136.8 (federal withholding) - $100.65 (state withholding) = $815.34. To record this in your register, you would add $815.34 to your current balance, which would bring your new balance to $1314.33

On October 24, you buy $78.54 in clothes from FitRight and pay 6% sales tax. To calculate the sales tax, you would multiply $78.54 by 0.06 and add that amount to the total cost of the clothes. The total cost of the purchase including sales tax would be $78.54 + $4.71 = $83.25. To record this in your register, you would subtract $83.25 from your current balance, which would bring your new balance to $1231.08

The standard deviation of the number of restaurants that failed within a year is 3.46.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Given that the probability that an independent restaurant will fail in the first year is 48%. Therefore, the probability can be written as,

p = 48% = 0.48

q = 1-p = 1-0.48 = 0.52

Also, Kristen obtains a random sample of 66 independent restaurants that opened in her city more than one year ago and determines if each one had closed within a year. Therefore, the sample size is 53.

n = 53

Now, the standard deviation can be calculated as,

Standard deviation, σ = √(npq)

                                    = √(53 × 0.48 × 0.52)

                                    = √11.9808

                                    = 3.46

B. -0.45

Step-by-step explanation:

I'm assuming the values you have provided are pertaining to the correlation coefficient.

The correlation coefficient (r) is used to describe how strongly points are correlated and in which direction they are correlated. This correlation coefficient ranges between -1 and 1: [tex]-1\le r\le1[/tex]

If the correlation coefficient is negative, the correlation is down-sloped or in other words as the variable on the x-axis increases, the variable on the y-axis decreases.

If the correlation coefficient is positive, the correlation is upward-sloped or in other words as the variable on the x-axis increases, the variable on the y-axis also increases.

The strength of the correlation can be analyzed by the absolute value of the correlation coefficient (r). So if you want to compare two correlation coefficients and say which has a stronger correlation, you would first take the absolute value and then compare which is larger as such: [tex]|r|[/tex]

In this case the -0.45 is technically less than the 0.34, although the absolute value indicates it is a stronger correlation, just in a different direction. You can compare all the other options and -0.45 has the largest absolute value.
