The answer will be option B. The net pay for the jacob will be equal to $6,188.

The amount paid by any company to the employees without any deductions like taxes or charges is called as the gross pay.

It is given that:-

Gross pay for the year was $8000

The federal tax rate he’ll need to pay is 10%.

Jacob will need to pay 5% and the FICA rate is 7.65%

So the total deductions from the gross pay will be calculated as:-

Deductions = 8000 X 10% +8000 x 5% +8000 x 7.5%

Deductions = 800+400+612=$1812

The net pay will be = 8000-1812 =$ 6188

Hence the net pay for the jacob will be equal to $6,188.

Answer:

−0.2226 ; 1.0226

Step-by-step explanation:

Given :

n1 = 10 ; n2 = 8 ; s1 = 0.5 ; s2 = 0.7 ; x1 = 3.1 ; x2 = 2.7

Confidence interval, two - sample, t procedure ;

μ1 - μ2 = (x1 - x2) ± Tcritical*S

S = sqrt[(s1²/n1) + (s2²/n2)]

S = sqrt[(0.5^2/10) + (0.7^2/8)]

S = sqrt[0.08625]

S = 0.2937

Tcritical at 95% confidence interval

df = 10+8 - 2= 16

Tcritical = 2.12

(3.1 - 2.7) ± 2.12*(0.2937)

Answer:

The total number of pairs of jeans in her wardrobe is 15.

Step-by-step explanation:

We solve this question using proportions.

6 pairs of jeans represents 40% of the total.

The total is x. Using proportions:

[tex]\frac{6}{x} = \frac{40}{100}[/tex]

[tex]\frac{6}{x} = 0.4[/tex]

[tex]0.4x = 6[/tex]

[tex]x = \frac{6}{0.4}[/tex]

[tex]x = 15[/tex]

The total number of pairs of jeans in her wardrobe is 15.

Answer:

The slope of the line is -1/2, and the entire equation should be y = -1/2x + 3/2

Step-by-step explanation:

Choose two points along the line, for this I chose (3,0) and (-1,2). Finding the slope from there should be (y2 - y1)/(x2-x1), or -1/2. To get the entire line use point slope form of y - y1 = slope (x -x1) with one of the points you already found.

Answer:

x+6=40

Subtract 6

x=34

Answer:

n + 6 = 40

n = 34

Step-by-step explanation:

Sum of a number and 6. That means you got to add n and 6.

'is' means you need to put an equal sign.

n + 6 = 40

Now, lets find what n is.

Isolate the variable by subtracting 6 from both sides.

n = 34

Answer:

1) mean = 21, standard deviation σ = 21.9317

2) the probability that Penelope's portfolio will earn at least 12% in the next 12 months is 0.6591

Step-by-step explanation:

 Given the data in the question;

1. According to Penelope's beliefs, what are the mean rate of return and the standard deviation of return of her portfolio?

Mean μ = Return = ( 60% × 15) + ( 40% × 30 ) = 9 + 12 = 21

mean = 21

standard deviation σ = √( (0.6² × 25²) + ( 0.4² × 40² ) )

standard deviation σ = √( (0.36 × 625) + ( 0.16 × 1600 ) )

standard deviation σ = √( 225 + 256 )

standard deviation σ = √481

standard deviation σ = 21.9317

2)  What is the probability that Penelope's portfolio will earn at least 12% in the next 12 months

so we are to find P( X > 12 )

converting into standard normal variable;

⇒ P( Z  > X-μ  / σ  )

= P( Z  > ( 12-21  / 21.9317  ) )

= P( Z  > ( -9 / 21.9317  ) )

= P( Z  > -0.41 )  

FROM z-score table; P( Z  > -0.41 ) is 0.3409

P( X > 12 ) = 1 - 0.3409

P( X > 12 ) = 0.6591

Therefore,  the probability that Penelope's portfolio will earn at least 12% in the next 12 months is 0.6591

Answer:

(8,-1)

Step-by-step explanation:

Given :  

To Find: solution of given system of equations.

Solution:

Equation a :  

Equation b :  

Substitute the value of y from equation b in equation a

y from equation b : y = 7-x

Now substitute value of y in equation a

Thus equation a becomes:

⇒ x= -1 and x = 8

Now substitute values of x  in equation b to obtains values of y

Thus (x,y)=(8,-1)

Hence Option A is the correct solution .

Answer:

1

Step-by-step explanation:

The answer is actually just positive 1.

Absolute value is the direct opposite of a number with a positive value on a number line. However, the absolute value is always answered in a positive form of the number meaning that no matter what the number is (even if it's a positive number) the answer will always be that same number, but in positive form.

Remember, if a number is in between two of these " | " then the answer will be that same number but in positive form.

Hope this helps and have a nice day.

Answer: 104

Step-by-step explanation:

It is a full circle

Circle = 360

We have 126 and 26 so

360 - (126+26) = 208

Since the a's are opposite thet means they are equal ( I forgot the law name)

208 divided by 2

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

7)

now decide which parts we know and what we want to slove for and pick the function that has those in it

we also know that small angle down at the point b/c we can use that the inside of trianle angles add to 180

180 = 75 + 90 + X

15° = X  

where x is the angle at that sharp point on the triangle

I want to use that 15° angle in one of the above formulas as it's Opposite of that side we want to know, and also adjcent to that side we know , so i'll pick TOA  since it's got all of those in it.  Opp = x for this triangle

Tan(15) =  Opp / 15

15* Tan(15) = Opp

4.0192 = Opp

so that's x  

x = 4.0162 units , what ever they are

8)

the angle is 43° and we know the adjacent side and we want the Hypotenuse , now i'll pic  CAH  since it's got those pieces in it

Cos(43)= 31 / Hyp

some algebra just to switch Hyp out of the denominator

Hyp = 31 / Cos(43)

some tapping on my calculator

Hyp = 41.714

That's x for the second triangle

x = 41.71 units , what ever they are

Answer:

x=27

Step-by-step explanation:

Hey there!

the exterior angles of a quadrilateral add up to equal 360

so 360=2x+40+4x+3x+x+50

step 1 combine like terms

2x+4x+3x+x=10x

50+40=90

now we have

360=10x+90

step 2 subtract each side by 90

360-90=270

90-90 cancels out

now we have 270=10x

step 3 divide each side by 10

270/10=27

we're left with

x=27
