Social Security= $217

Medicare = $‭50.75‬

Net Pay is $‭2,633.67‬

First, Taxable income is therefore;

= 3,500 - (76.90 x 4 )

= $‭3,192.4‬0

Federal Income Tax (FIT).

With taxable income of $‭3,192.4‬0, the tax is $565.15 plus 28% of anything above $‭3,073.

= 565.15 + (28% x (‭3,192.4‬0 - 3,073))

= 565.15 + 33.43

= $‭598.58

and, Social Security

= Gross pay x 6.2%

= 3,500 x 6.2%

= $‭217‬

and, Medicare

= 3,500 x 1.45%

= $‭50.75‬

Then, the Net Pay

= 3,500 - 598.58 - 217 - 50.75

= $‭2,633.67‬

The distance that Mr. Stein drove can be represented by the expression: \(140 - x\)

A mathematical phrase made up of one or more variables, constants, and arithmetic operations like addition, subtraction, multiplication, and division is known as an algebraic expression. Exponentiation and other mathematical operators could also be present.

Let's assume that Mr. Smith drove "x" miles before Mr. Stein took over the driving.

Then, the total distance they traveled is 140 miles.

So, the distance that Mr. Stein drove can be represented by the expression:

140 - x

Therefore, This is because if Mr. Smith drove "x" miles, then the remaining distance that needed to be covered by Mr. Stein would be the difference between the total distance of 140 miles and the distance already driven by Mr. Smith.

The value of y is 4√3

Similar triangles have the same corresponding angle measures and proportional side lengths. The corresponding angles of similar triangles are congruent or equal.

Also , the ratio of corresponding sides of similar triangles are equal.

There are two triangles that are similar

Therefore;

y /16 = 4/y

y² = 48

y = √48

y = √16 × √ 3

The amount of Duane's first payment that goes to interest is approximately $26.47.

To determine the amount of Duane's first payment that goes to interest, we need to use the amortization formula for a loan.

The formula to calculate the interest portion of a loan payment is:

Interest = Remaining Balance * Monthly Interest Rate.

Let's calculate the interest for the first payment using the given information:

Loan Amount = $5,000.00

Monthly Payment = $118.57

First, we need to calculate the monthly interest rate:

Monthly Interest Rate = Annual Interest Rate / 12

= 6.5% / 12

= 0.00542

Next, we need to calculate the remaining balance after the first payment:

Remaining Balance = Loan Amount - Principal Paid

= $5,000.00 - $118.57

= $4,881.43

Finally, we can calculate the interest portion of the first payment:

Interest = Remaining Balance * Monthly Interest Rate

= $4,881.43 * 0.00542

= $26.47

Answer:

A. y = -x + 8

Step-by-step explanation:

y = mx + c

m = \(\frac{y2 - y1}{x2 - x1}\) = \(\frac{0 - 8}{8 - 0}\) = -1

c = 8

=> The equation will be y = -1x + 8 or y = -x + 8.

Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

The greatest distance, in feet, a person could be from the lamp and be detected is: B. 12 ft

The equation (x+16)² + (y-13)² = 36 describes a circle with center (-16,13) and radius 6. The motion detector on the lamp post can detect motion within this circle.

To find the greatest distance a person could be from the lamp and still be detected, we need to find the diameter of the circle, which is equal to twice the radius. Therefore, the greatest distance a person could be from the lamp and still be detected is 2(6) = 12 feet.

Therefore, the correct answer is B) 12 ft.

Answer:

Expected time is 15 hours for him to get to safety.

Step-by-step explanation:

We define X as the time that this miner would get to safety.

We define Y as the door he chooses initially.

P(Y= 1) = P(Y=2)=P(Y=3) = 1/3

We have E[X|Y=1] = 3

E[X|Y] = 5 hours + E[X}

E[X|Y] = 7 hours + E[X]

Then we have

E[X] = 1/3(3 + 5 + E[X] + 7 + E[X])

We cross multiply

3*E[X] = (15 + 2E[x])

3E[X] - 2E[X] = 15

E[X] = 15

So the time it would take to get him to safety is 15 hours

The correlation coefficient for x1 and y is 0.91, The correlation coefficient for x2 and y is 0.55 and The correlation coefficient for x1 and x2 is -0.33

Calculating the Correlation Coefficient for x1 and y:

Step 1: Calculate the mean of x1:  Mean of x1 = (30 + 46 + 24 + 51 + 41 + 51 + 74 + 37 + 60 + 77) / 10  Mean of x1 = 47.1

Step 2: Calculate the mean of y:  Mean of y = (94 + 109 + 112 + 178 + 94 + 176 + 171 + 117 + 142 + 212) / 10  Mean of y = 134.1

Step 3: Calculate the standard deviation of x1:  Standard Deviation of x1 = √(((30 - 47.1)2 + (46 - 47.1)2 + (24 - 47.1)2 + (51 - 47.1)2 + (41 - 47.1)2 + (51 - 47.1)2 + (74 - 47.1)2 + (37 - 47.1)2 + (60 - 47.1)2 + (77 - 47.1)2) / 10)

Standard Deviation of x1 = 17.43  

Step 4: Calculate the standard deviation of y:  Standard Deviation of y = √(((94 - 134.1)2 + (109 - 134.1)2 + (112 - 134.1)2 + (178 - 134.1)2 + (94 - 134.1)2 + (176 - 134.1)2 + (171 - 134.1)2 + (117 - 134.1)2 + (142 - 134.1)2 + (212 - 134.1)2) / 10)

Standard Deviation of y = 38.82  

Step 5: Calculate the covariance of x1 and y:  Covariance of x1 and y = ((30 - 47.1) × (94 - 134.1) + (46 - 47.1) × (109 - 134.1) + (24 - 47.1) × (112 - 134.1) + (51 - 47.1) × (178 - 134.1) + (41 - 47.1) × (94 - 134.1) + (51 - 47.1) × (176 - 134.1) + (74 - 47.1) × (171 - 134.1) + (37 - 47.1) × (117 - 134.1) + (60 - 47.1) × (142 - 134.1) + (77 - 47.1) × (212 - 134.1)) / 10  

Covariance of x1 and y = 393.3

Step 6: Calculate the correlation coefficient of x1 and y:

Correlation Coefficient of x1 and y = Covariance of x1 and y / (Standard Deviation of x1 × Standard Deviation of y)  = 393.3 / (17.43 × 38.82)

Correlation Coefficient of x1 and y = 0.91

Answer:

\(-2\dfrac{3}{8}\)

Step-by-step explanation:

Given the expression:

\(3\dfrac78 - 6\dfrac14\)

We are to simplify and obtain an equivalent expression.

Step 1: Change to Improper Fractions

\(3\dfrac78 - 6\dfrac14=\dfrac{31}{8}-\dfrac{25}{4}\)

Step 2: Take the Lowest Common multiple of the denominators

LCM of 8 and 4 is 8.

Therefore:

\(\dfrac{31}{8}-\dfrac{25}{4}=\dfrac{31-2(25)}{8}\\\\\dfrac{31-50)}{8}\\\\=-\dfrac{19}{8}\\\\=-2\dfrac{3}{8}\)

Therefore, an equivalent expression to \(3\dfrac78 - 6\dfrac14\) is \(-2\dfrac{3}{8}\).

(90-35)-7/4

Answer:

x=12

Step-by-step explanation:

Since the two angles are complementary, both angles add up to 90°.

So, to find the value of the other angle, simply subtract 35 from 90.

90-35=55

Now we know that the expression is equal to 55.

4x+7=55

Subtract 7 from both sides.

4x=48

Divide both sides by 4.

x = 12
