Answer:

A) mea culpa

Step-by-step explanation:

The solution is Option A.

The amount of income left over after paying the federal income tax is given by the equation A = $ 24,490.00

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 amount of income left over be represented as A

Now , the equation will be

The amount of taxable income is $31,850.00

And , the taxable income is in the range $ 8,350 - $ 33,950

So , the fixed tax for the amount is $ 835.00

The percentage of tax is 15 % of the amount over

So , the amount over = $ 8,350

Substituting the values in the equation , we get

The amount over = $31,850.00 - $ 8,350.00

The amount over = $ 23,500.00

Now , 15 % of amount over = 23,500 x ( 15/100 )

15 % of amount over = $ 3,525.00

And , Total tax = 15 % of amount over + fixed tax for the amount

Total tax = $ 3,525.00 + $ 835.00

Total tax = $ 4,360.00

Now , the amount of income left over A = amount of taxable income - Total tax

Amount of income left over A = $31,850.00 - $ 4,360.00

Amount of income left over A = $ 27,490.00

Therefore , the value of A is $ 27,490.00

Hence , the amount left over is $ 27,490.00

Answer:

72°

Step-by-step explanation:

From the information given:

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Avenue.

We are also told that there is a  Trapezoid EFGH with EH as the Pine avenue and EF as the Elm street.

However, side FG and EH are parallel.

∠G = 108°

From the property of parallel lines :

since FG || EH

Then  ∠G = ∠H  = 108°  (i.e corresponding angle will also be equal)

The required angle between Elm Street and Pine Avenue would be interior angles +  180°  given that  alternate angles are also equal.

The required angle between Elm Street and Pine Avenue = 180° - 108°

The required angle between Elm Street and Pine Avenue = 72°

Answer:

B. 72

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

Since, DE || AC... (GIVEN)

Therefore, by Basic Proportionality Theorem, we have:

BD/AD = BE/CE

(10-x) / x = 3/2

2(10 - x) = 3x

20 - 2x = 3x

20 = 2x + 3x

20 = 5x

x = 20/5

x = 4

Answer:

Step-by-step explanation:

Hello, do you agree that for any real number a (different from 0)

[tex]\dfrac{a}{a}=1[/tex]

?

5/5 = 1 for instance.

So, when you have the same common factor at the numerator and at the denominator you can eliminate it. For instance.

[tex]\dfrac{10}{4}=\dfrac{5*2}{2*2}=\dfrac{5}{2}\cdot \dfrac{2}{2}=\dfrac{5}{2}[/tex]

You just need to be careful with 0, as dividing by 0 is not allowed.

Hope this helps

Thank you.

Answer:

Step-by-step explanation:

An equilateral triangle has 3 equal sides.

So

4(x-1) = x +8

4x-4=x+8

3x=12

x=4

Same result obtained when comparing the other pairs of equations.

Answer:

107

Step-by-step explanation:

Hello, Let's note n the odd number that we are looking for.

If n is odd, n+1 is even but n+2 is odd again and so on and so forth.

So, the 16 consecutive odd numbers are

n, n+2, n+4, ... n+2k, ,,,, ,n+30

It means that the average is:

[tex]\displaystyle \dfrac{1}{16}(n+(n+2)+...+(n+2k)+...+(n+2*15))\\\\=\dfrac{1}{16}\sum_{k=0}^{k=15} {(n+2k)}\\\\=\dfrac{1}{16}\left(n * 16 + 2 \sum_{k=1}^{k=15} {k} \right)\\\\=\dfrac{1}{16}\left(n * 16 + 2 (\dfrac{15*16}{2}) \right)\\[/tex]

And it must be equal to 122, so we can write.

[tex]\dfrac{1}{16}\left(n * 16 + 2 (\dfrac{15*16}{2}) \right)=122\\\\n+15=122\\\\n = 122-15=107[/tex]

Answer: y=2x+2

Step-by-step explanation:

slope-intercept form: y=ax+b

----------------------------------------

#1 Find the slope

- Use rise/run to find the slope: 8/4=2

- Use slope formula: (2-(-6))/(0-(-4))=8/4=2

#2 Find the y-intercept

- Given the point (2, 0) it is already the y-intercept which is 2

----------------------------------------

a=2

b=2

y=2x+2

Work Shown:

The set {A,B,C,1,2} has five items. There are four slots to fill.

So we have 5^4 = 5*5*5*5 = 625 different possible passwords where the characters can be repeated.

625 four-character passwords can be formed.

----------------------------

Each character of the password is independent of previous characters, which means that the fundamental counting principle is used to solve this question.

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

----------------------------

Thus, the number of passwords is:

[tex]5 \times 5 \times 5 \times 5 = 5^4 = 625[/tex]

625 four-character passwords can be formed.

Answer:

Step-by-step explanation:

Hi!

First we need to translate 2 units down. That means we need to subtract 2 from the y value. So now we have (-1,1).

For a 270 degree counterclockwise rotation the rule is to go from (x,y) to (y,-x)

So now we have (1,1). Since they're only asking for the x value, the answer is 1.

Answer:

[1, 1]

Step-by-step explanation:

Translation → [-1, 3] moves down to [-1, 1]

Now, a 90°-clockwise rotation is the exact same as a 270°-counterclockwise rotation, and according to the 270°-counterclockwise rotation [90°-clockwise rotation] rule, you take the y-coordinate, bring it over to your new x-coordinate, and take the OPPOSITE of the x-coordinate and set it as your new y-coordinate:

Extended Rotation Rules

270°-clockwise rotation [90°-counterclockwise rotation] >> (x, y) → (-y, x)

270°-counterclockwise rotation [90°-clockwise rotation] >> (x, y) → (y, -x)

180°-rotation >> (x, y) → (-x, -y)

Then, you perform your rotation:

270°-counterclockwise rotation [90°-clockwise rotation] → [-1, 1] moves to [1, 1]

3. Formula of a Cylinder + Formula of a Cone = Total

V=πr^2h + V=πr^2h

/3 = total

V = 3.14 * 36 * 10 + V = 3.14 * 36 * 10/3

V = 1,130.4 + V = 376.8 = Total

4. Formula of Cone + Formula of Cone = Total

V=πr^2h

/3 + V=πr^2h

/3 = Total

V = 3.14 * 36 * 8/3 + V = 3.14 * 100 * 8 = Total

V = 301.44 + 2,512 = Total

5. Formula of a cylinder + formula of a sphere = Total

V=πr^2h + V=4

Answer:

definite integral I = 0.001591  to six decimal places

Step-by-step explanation:

The definite integral is given as:

[tex]\int ^{0.1}_{0} \ x \ arctan (5x) \ dx[/tex]

For arctanx , the power series is in the order [tex]x - \dfrac{x^3}{3}+ \dfrac{x^5}{5}-\dfrac{x^7}{7}+...[/tex]

[tex]arc tan \ x = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ x ^{2n+1}}{2n +1}[/tex]

The next step is to substitute the value of 5x for x in the above equation;

So,

[tex]arc tan \ (5x) = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ (5x) ^{2n+1}}{2n +1}[/tex]

To  multiply both sides by (x); we have

[tex]x\ arc tan \ (5x) = x \ \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5 ^{2n+1} \times x^{2n+1}}{2n +1}[/tex]

[tex]x\ arc tan \ (5x) = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5 ^{2n+1} \times x^{2n+2}}{2n +1}[/tex]

Taking the integral on both sides with respect to x;

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1}}{2n+1} \ \int ^{0.1}_0 x^{2n+2} \ dx[/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1}}{2n+1} \ [(0.1)^{2n+3}][/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1} \times (0.1)^{2n+3} }{(2n+1)(2n+3)}[/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = [\dfrac{5 \times (0.1)^3}{1.3}-\dfrac{5^3(0.1)^3}{3.5}+\dfrac{5^5(0.1)^7}{5.7}-\dfrac{5^7(0.1)^9}{7.9}+ ...][/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = [\dfrac{1}{600}-\dfrac{1}{1200}+\dfrac{1}{112000}-\dfrac{1}{806400}+ ...][/tex]

Step-by-step explanation:

Answer:

yhat=1.36+0.74x

when x=7 then yhat=6.54

Step-by-step explanation:

Th regression equation is

yhat=a+bx

where slope b is

[tex]b=\frac{nsumxy-(sumx)(sumy)}{nsumx^{2}-(sumx)^{2} }[/tex]

and intercept a is

a=ybar-bxbar

x   4   5   2   6    9

y   4   6   2   7    7

xy 16 30  4  42  63

x² 16 25  4  36  81

n=5.

sumx=26.

sumy=26.

sumx²=162.

sumxy=155.

[tex]b=\frac{5*155-(26)(26)}{5*162-(26)^{2} }[/tex]

[tex]b=\frac{99}{134 }[/tex]

b=0.7388

b=0.74 (rounded to 2 decimal places)

xbar=sumx/n=26/5=5.2

ybar=sumy/n=26/5=5.2

a=ybar-b*xbar

a=5.2-0.7388*5.2

a=5.2-3.8418

a=1.3582

a=1.36 (rounded to 2 decimal places)

Thus, the required regression equation is

yhat=1.36+0.74x

When x is 7 this gives yhat

yhat=1.36+0.74*7

yhat=1.36+5.18

yhat=6.54
