If their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

The term taxable income refers to any gross income earned that is used to calculate the amount of tax you owe. Put simply, it is your adjusted gross income less any deductions. This includes any wages, tips, salaries, and bonuses from employers.

The minimum income amount depends on your filing status and age. In 2022, for example, the minimum for single filing status if under age 65 is $12,950. If your income is below that threshold, you generally do not need to file a federal tax return. Review the full list below for other filing statuses and ages.

Taxable income

a. Taxable income:

Taxable income=Gross income - Total taxes due

Taxable income=$63,000-$6,847.50

Taxable income=$56,152.5

b. The marginal tax rate for taxable income  under the income bracket of of $40,526 to $86,375 is 22%.

c. Effective tax rate:

Effective tax rate = Total taxes due/ Taxable income×100

Effective tax rate =$6,847.50/$56,152.5×100

Effective tax rate =10.869%

Effective tax rate =10.87% (Approximately)

Inconclusion if their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

A system of inequalities to represent the constraints of this problem are x ≥ 0 and y ≥ 0.

A graph of the system of inequalities is shown on the coordinate plane below.

In order to write a system of linear inequalities to describe this situation, we would assign variables to the number of HD Big View television produced in one day and number of Mega Tele box television produced in one day respectively, and then translate the word problem into algebraic equation as follows:

Since the HD Big View television takes 2 person-hours to make and the Mega TeleBox takes 3 person-hours to make, a linear equation to describe this situation is given by:

2x + 3y = 192.

Additionally, TVs4U’s total manufacturing capacity is 72 televisions per day;

x + y = 72

For the constraints, we have the following system of linear inequalities:

x ≥ 0.

y ≥ 0.

Expected number of free throws in 80 attempts:

Best player = 64

2nd best player = 60

3rd best player = 52

We have to given that,

The probability that best player makes free throw, p1 = 0.8

The probability that second-best player makes free throw, p2 = 0.75

The probability that third-best player makes free throw, p3 = 0.65

Here, Total number of attempts made in free throws, n = 80.

Since, The estimated number of free throws that any player makes is defined by:

E ( Xi ) = n × pi

Where, Xi = Player rank

 pi = Player rank probability

Hence, Expected value for best player making the free throws would be:

E (X1) = n × p1

         = 80 x 0.8

         = 64 free throws

Expected value for second-best player making the free throws would be:

E (X2) = n*p2

= 80 x 0.75

= 60 free throws

Expected value for third-best player making the free throws would be:

E (X3) = n*p3

= 80  x 0.65

Answer:

75%

Step-by-step explanation:

We are given that Sara bought a chest for $42, and then sold it for $73.50.

Recall that when finding by how much something was marked up, you should use the following formula:

(new price-original price)/(original price)

Let's substitute the values, like so:

\(\frac{73.50-42}{42}=\\\\ \frac{31.50}{42}\)

Now, set up a proportion to find what this fraction is as a percentage:

\(\frac{31.5}{42} =\frac{x}{100} =\\42x=3150=\\x=75\)

So, the price was marked up by 75%.

805/24 divided by 2 » (805/24) ÷ 2 » 33.5416666667 ÷ 2 = 16.7708333333 . Check 805/24 long division below

The total lease cost assuming that the deposit is nonrefundable is $14046.

The term "Leasing Costs" refers to all fees paid or benefits granted to a tenant under an existing lease or a new lease, including I commissions for leasing or brokerage services, (ii) direct payments, tenant improvement allowances, work letters, or free rent, and (iii) rent allowances or rent credits.

Given:

Length of lease: 24 months

MSRP of the car: $21,400

Purchase value of the car after lease: $17,100

So, Monthly payment= $479

So, Monthly payment after 24 month

= 11496

Thus, total lease cost =  Down payment + Security deposit + Acquisition

                                                                                                             fee

                                                               + payment for 24 months

Total lease cost = 1500+ 350+ 700+ 11496

                           = $14046

Hence, the lease cost is $14046.

Step-by-step explanation:

Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?

Total pages of the book = x

Tuesday = 30%

= (30/100)x

= 3/10x

Wednesday = 1/5x

3/10x + 1/5x

= 3x+2x/10

= 5/10x

Using the segment addition postulate, the value of p = 5, and YZ = 9 units.

Since point Y lies between points X and Z, the three points are collinear, therefore, based on the segment addition postulate, XY + YZ = XZ.

Given the following:

XY = 3p

YZ = 2p - 1

XZ = 6p - 6

Substitute

3p + 2p - 1 = 6p - 6

Add like terms

5p - 1 = 6p - 6

5p - 6p = 1 - 6

-p = -5

p = 5

YZ = 2p - 1

Plug in the value of x

YZ = 2(5) - 1

YZ = 9 units.

Answer:

Solve for b: b = 6 - a

Solve for a:  a = 6 - b

Step-by-step explanation:

There are two ways we can solve this, solve for a and solve for b.

Lets solve for b first

\(4-b=2-a\)

Add 4 on both sides

\(b=2-a+4\)

Simplify

\(b=6-a\)

Now lets solve for a

\(4-b=2-a\)

Flip the equation

\(2-a=4-b\)

Add 2 on both sides

\(a=4-b+2\)

Step-by-step explanation:

1. The values which the given number sentences true are:

a) 11 b) 5 c) 36

2. After substituting the value of  x we get the value for y as :

a) 6 b) 0 c) 7 d) 15

3. The number sentences are :

a) x ₋ y = 25

b) 5 × p = q ÷ 2

c) 2y ₋ 14 = 6

d) 15 × 4 = 4 ₋ (x₊y)

Given in the first bit we need to find the variables:

a) h ₊ 8 = 19

arrange the constants on one side.

h = 19 ₋ 8

h = 11

b) 2p ₋ 6 = 4

arrange the constants on one side.

2p = 4 ₊ 6

2p = 10

p = 10/2

p = 5

c) 1/3 y = 12

cross multiply.

y = 36

Now in the second exercise we are asked to substitute the x value and get the value of y.

a) y = 3x ₊ 2 if x =8

substitute x value in the equation.

y = 3(8) ₊ 2

y = 24 ₊ 2

y = 26

b) y = 4x ₋ 1 if  x = 1/4

y = 4(1/4) ₋ 1

y = 1 ₋ 1

y = 0

c) y = 0.2x ₊ 5 if x = 10

y = 0.2(10) ₊ 5

y = 2 ₊ 5

y = 7

d) y = 10x ₊ 12 if x = 0.3

y = 10(0.3) ₊ 12

y = 3 ₊ 12

y = 15

In the last third bit we need to frame equations for the given word problems.

a) The difference between two numbers is 25.

let the two numbers be x and y.

x ₋ y = 25.

b) The product of 5 and p is equal to quotient of q and 2.

5 × p = q ÷ 2

c) The difference between 14 and 2y is equal to 6.

2y ₋ 14 = 6

d) The product of 15 and 4 is equal to four less than the sum of x and y.

Answer:

If you are measuring the length of the pen it would be millimeter, if you are measuring volume it would be a liter. Hope this helps!

Answer:

A- 480

Step-by-step explanation:

First, I'm going to work out 25% of 1200 for the before 1980 pennies.

10% = 120

20% = 240

5% = 60

240 + 60 = 300 pennies before 1980.

Next, work out 35% of 1200 instead.

20% = 240

+ 10%

30% = 360

+ 5% = 60

35% = 420 pennies from 1980-2000

Finally, work out how many pennies are leftover.

300 + 420 = 720

1200 - 720 = 480

A is the answer.

A slope parameter of β1 = 3.52 in a simple linear regression model suggests that there is a positive and direct relationship between the independent variable (x) and the dependent variable (y).

Specifically, for every one unit increase in the independent variable (x), the dependent variable (y) is expected to increase by an average of 3.52 units. This indicates a positive linear association between x and y, implying that as x increases, y tends to increase as well.

The magnitude of the slope parameter (3.52) also indicates the steepness of the relationship. A larger slope suggests a stronger relationship, indicating that the change in y for a given change in x is relatively large.

Graph A is most likely to represent the daylight for the month after the spring equinox because it shows a straight line with a positive slope.

Graph D is most likely to represent the daylight for the month after the autumnal equinox because it shows a straight line with a negative slope.

Graph E shows a gradual increase in daylight, but it is not a straight line, which suggests that the rate of change is not constant over time.

What is the Graph?

In mathematics, a graph is a collection of nodes or vertices that are connected by edges or links.

As per the given information, the daylight gained after the spring equinox and the daylight lost after the autumnal equinox are both at a rate of 2 minutes per day. Based on this information, we can make some educated guesses about the shape of the graphs.

1. Which of the graphs is most likely to represent the graph of daylight for the month after the spring equinox?

The daylight gained after the spring equinox should gradually increase over time at a constant rate of 2 minutes per day. Therefore, the graph that most likely represents the daylight for the month after the spring equinox is a straight line with a positive slope.

Out of the given graphs, Graph A is most likely to represent the daylight for the month after the spring equinox because it shows a straight line with a positive slope.

2. Which of the graphs is most likely to represent the graph of daylight for the month after the autumnal equinox?

The daylight lost after the autumnal equinox should gradually increase over time at a constant rate of 2 minutes per day. Therefore, the graph that most likely represents the daylight for the month after the autumnal equinox is a straight line with a negative slope.

Out of the given graphs, Graph D is most likely to represent the daylight for the month after the autumnal equinox because it shows a straight line with a negative slope.

3. Why are the other graphs not likely to represent either month?

Graphs B and C both show irregular patterns that do not follow a consistent rate of change over time, which is not consistent with the information provided about daylight changing at a constant rate of 2 minutes per day. Therefore, they are not likely to represent either month.

Graph E shows a gradual increase in daylight, but it is not a straight line, which suggests that the rate of change is not constant over time.

As per the borrowed amount, the value of IRR is 6.40%

The term IRR is the internal rate of return is a metric used in financial analysis to estimate the profitability of potential investments.

Here we have know that Maggie green just borrowed $5,000. she is planning to pay it back in 5 equal installments of $1,200.

Now, we have to calculate the value of IRR,

The general form of the IRR formula is written as,

=> NPV = \(\sum\limits^T_{t=1} {\frac{C_t}{(1+r)^t} }\ -C_0\)

where r is the discount rate / interest rate and T is the number of cash flow periods with t denoting a specific period, C0 is the initial investment while Ct is the return during period t.

Here we apply the values on it, then we get,

=> \(NPV = \sum\limits^5_{t=1} {\frac{1200_t}{(1+r)^t} }\ -5000\)

When we simplify this one then we get,

=> Internal Rate of Return = 6.402%
