The tax rate for social security is 6.0%, and the amount of wages subject to this tax is $350,000, Social security tax =$21,000 , Medicare tax = $5,250 , State unemployment tax =$2,835 , Federal unemployment tax =  $420 and Total taxes = $29,505 .

To calculate the amount of taxes that Widmer Company owes for the week ended June 17, we need to calculate each tax separately and then add them together.

First, let's calculate the social security tax. The tax rate for social security is 6.0%, and the amount of wages subject to this tax is $350,000. So:

Social security tax = 6.0% x $350,000 = $21,000

Next, let's calculate the Medicare tax. The tax rate for Medicare is 1.5%, and the amount of wages subject to this tax is also $350,000. So:

Medicare tax = 1.5% x $350,000 = $5,250

Now let's calculate the state unemployment tax. The tax rate for state unemployment is 5.4%, and the amount of wages subject to this tax is $52,500. So:

State unemployment tax = 5.4% x $52,500 = $2,835

Finally, let's calculate the federal unemployment tax. The tax rate for federal unemployment is 0.8%, and the amount of wages subject to this tax is also $52,500. So:

Federal unemployment tax = 0.8% x $52,500 = $420

Now let's add up all of the taxes:

Total taxes = Social security tax + Medicare tax + State unemployment tax + Federal unemployment tax

Total taxes = $21,000 + $5,250 + $2,835 + $420

Total taxes = $29,505

This means that Widmer Company owes $29,505 in taxes for the week ended June 17.

Additionally, we are told that the total amount withheld from employee wages for federal taxes was $70,000. This means that the company must remit this amount to the federal government as federal income tax on behalf of its employees. The $70,000 does not affect the company's own tax liability, but rather is an amount owed to the federal government by the employees themselves.

Answer:

It would fall on the upper line.

Step-by-step explanation:

I can look at each line and see the equation for each.

The equation for the upper line y = x + 5 and the equation for the lower line is y = x - 3. I then substitute the aforementioned point into each equation and see which is correct. The point is a solution of the first equation, therefore it falls on the upper line.

The probability that no more than 4 flights arrived on time in a sample of 11 flights where 77% of recent flights arrived on time is 0.19036 or 0.0046 (rounded to four decimal places).

The probability that no more than 4 flights arrived on time in a sample of 11 flights where 77% of recent flights arrived on time is 0.0046.

Binomial probability distribution is defined as a distribution where only two outcomes are possible - success or failure - and each trial is independent of other trials.

A binomial experiment is one that meets the following four conditions:

1. Each trial has only two outcomes (success or failure).

2. The probability of success remains constant across all trials.

3. The trials are independent of each other.

4. The experiment involves a fixed number of trials.

In this case, the probability of success is 77% or 0.77 since that is the probability that a recent flight arrives on time.

The probability of failure is 1 - 0.77 = 0.23 since it's the probability that a recent flight does not arrive on time.

Let's use these values to solve the problem.

The probability of no more than 4 flights arriving on time in a sample of 11 flights where 77% of recent flights arrived on time is given by the cumulative probability of x ≤ 4, which is equal to:

P(x ≤ 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4)

where:P(x = 0) = (11 C 0) (0.77)0 (0.23)11 = 0.0001267

P(x = 1) = (11 C 1) (0.77)1 (0.23)10 = 0.0017314

P(x = 2) = (11 C 2) (0.77)2 (0.23)9 = 0.0115321

P(x = 3) = (11 C 3) (0.77)3 (0.23)8 = 0.0474373

P(x = 4) = (11 C 4) (0.77)4 (0.23)7 = 0.1295333

Now we can add these values to find the probability of no more than 4 flights arriving on time in a sample of 11 flights:

P(x ≤ 4) = 0.0001267 + 0.0017314 + 0.0115321 + 0.0474373 + 0.1295333= 0.19036

The farmer sold approximately 3.905 kilograms of pears at the farmer's market. In fraction form, this is 781/200 kilograms.

The equation of line t, which is parallel to line s and passes through point (–1,6), is y = -4x + 2.

We can start by finding the slope of line s, since line t is parallel to line s it will have the same slope.

y – 2 = –4(x + 1) [Given equation of line s in point-slope form]

y – 2 = –4x – 4 [Distribute -4 on the right side]

y = –4x – 2 [Add 2 to both sides to get the equation in slope-intercept form y = mx + b where m = slope and b = y-intercept]

So the slope of line s is -4.

Since line t is parallel to line s, it will also have a slope of -4. Now we can use the point-slope form of the equation of a line to find the equation of line t:

y - y1 = m(x - x1) [Point-slope form of the equation of a line]

We know that line t includes the point (–1,6), so x1 = –1 and y1 = 6. Also, the slope of line t is m = -4. Substituting these values in the point-slope form, we get:

y - 6 = -4(x - (-1))

y - 6 = -4(x + 1)

y - 6 = -4x - 4

y = -4x + 2

Therefore, the equation of line t is y = -4x + 2.

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

Let's start with the ratio of the size of angle DEA to the size of angle CDE. We can express this ratio as:

angle DEA : angle CDE = 5 : 2

We know that the sum of the angles in a triangle is 180 degrees, so we can use this fact to express angle DEA and angle CDE in terms of angle ABD:

angle DEA + angle CDE + angle ABD = 180

Substituting the ratio given above, we get:

5x + 2x + angle ABD = 180

Simplifying, we get:

7x + angle ABD = 180

Next, let's consider the ratio of the size of angle EAB to the size of angle ABC, which is given as 4:3. We can express this ratio as:

angle EAB : angle ABC = 4 : 3

We know that angle EAB and angle ABC are adjacent angles, so their sum is equal to angle ABD:

angle EAB + angle ABC = angle ABD

Substituting the ratio given above, we get:

4y + 3y = angle ABD

Simplifying, we get:

7y = angle ABD

Now we have two equations:

7x + angle ABD = 180

7y = angle ABD

We can substitute the second equation into the first to get an equation in terms of y:

7x + 7y = 180

Simplifying, we get:

x + y = 25.71

Now we can use the ratio of angle EAB to angle ABC to find y:

angle EAB : angle ABC = 4 : 3

4y : 3y = 4 : 3

Simplifying, we get:

4y = 3(106 - angle EAB)

Expanding, we get:

4y = 318 - 3angle EAB

Substituting the equation we found for y above, we get:

4(25.71 - x) = 318 - 3angle EAB

Simplifying, we get:

angle EAB = 70.76

Therefore, the size of angle EAB is approximately 70.76 degrees.

Only option B) 3, 4, and 5 forms a right triangle.

What is the Pythagorean theorem?

In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This is known as the Pythagorean theorem.

So, to check which set of side lengths form a right triangle, we need to see if they satisfy this condition.

A) 3, √9,√18:

√9 is equal to 3, so we have the side lengths 3, 3√2.

Using the Pythagorean theorem:

(3)² + (3√2)² = 9 + 18 = 27

However, (√18)² is also equal to 18, so the set of side lengths can also be written as 3, 3√2, √18.

Using the Pythagorean theorem again:

(3)² + (3√2)² = 9 + 18 = 27

and (3)² + (√18)² = 9 + 18 = 27

So, we have two sides that can form a right triangle, but not all three.

B) 3, 4, 5:

Using the Pythagorean theorem:

(3)² + (4)² = 9 + 16 = 25

Since 5² is also equal to 25, these side lengths form a right triangle.

C) 7, 7, √98:

√98 can be simplified as 7√2. So, we have the side lengths 7, 7, 7√2.

Using the Pythagorean theorem:

(7)² + (7)² = 98

and (7)² + (7√2)² = 343 + 98 = 441

So, we don't have a right triangle in this case.

Therefore, only option B) 3, 4, and 5 forms a right triangle.

The common ratio is 1/3 and the fifth term of a geometric progression (GP) is 2/81 if the first and third terms of the GP are 2 and 2/9, respectively.

Let's call the common ratio of the GP "r".

We know that the first term of the GP is 2, so:

a₁ = 2

We also know that the third term of the GP is 2/9, so:

a₃ = 2/9

We can write the following using the nth term of a GP formula:

a₃ = a₁ * r²

Substituting the values we know, we get:

2/9 = 2 * r²

Dividing both sides by 2, we get:

1/9 = r²

Taking the square root of both sides (and remembering that r must be positive since it's a common ratio), we get:

r = 1/3

Now we can find the fifth term of the GP using the formula:

a₅ = a₁ * r⁴

Substituting the values we know, we get:

a₅ = 2 * (1/3)⁴

a₅ = 2 * (1/81)

a₅ = 2/81

Therefore, the common ratio is 1/3 and the fifth term of the GP is 2/81.

To construct a vector diagram showing the net magnetic field vector at point P, we can use the right-hand rule for determining the direction of the magnetic field around a current-carrying wire.

If we curl the fingers of our right hand in the direction of the current in the first wire, which is out of the page, the thumb points in the direction of the magnetic field at point P due to the first wire. Similarly, in the opposite direction to the magnetic field at point P due to the second wire.

Since the magnetic fields they produce at P have equal magnitudes but opposite directions. Therefore, the net magnetic field at P is zero,

If a third wire carrying equal current into the plane of the paper were located at P, the direction of the force on this wire would be perpendicular to both the magnetic field produced by the other two wires and the direction of the current in the third wire.

Answer:

0.13188 km

Step-by-step explanation:

The distance covered by the bicycle wheel can be calculated using the formula:

distance = circumference x number of revolutions

The circumference of the wheel can be calculated using the formula:

circumference = 2 x pi x radius

where pi is approximately equal to 3.14.

Substituting the given values:

circumference = 2 x 3.14 x 30 cm

circumference = 188.4 cm

Now, we can calculate the distance covered by the wheel:

distance = circumference x number of revolutions

distance = 188.4 cm x 70

distance = 13188 cm

To convert this distance from centimeters to kilometers, we need to divide by 100,000 (since there are 100,000 centimeters in a kilometer):

distance = 13188 cm ÷ 100,000

distance = 0.13188 km

Therefore, the distance covered by the bicycle wheel is approximately 0.13188 km.

Therefore, the odds of rolling an even number, getting a tail, and pulling a red card are 1 in 8 or 1/8.

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It involves calculating the likelihood or chance of an event occurring based on the available information and assumptions. Probability is commonly used in many fields, including science, engineering, finance, and statistics. The probability of an event is a number between 0 and 1, where 0 means the event is impossible, and 1 means the event is certain.

The optimal number of bags to purchase is 174 bags.

To determine the optimal number of bags to purchase, we need to consider the trade-off between the cost of holding excess inventory and the cost of not having enough inventory to meet demand.

Let's assume that the cost of holding one bag of inventory for six months is $2.00, and the cost of not having one bag available when needed is $10.00.

We can use the normal distribution to estimate the probability of demand exceeding our inventory level. If we assume that demand follows a normal distribution with mean 150 and standard deviation 60, then we can calculate the probability of running out of inventory as

P(demand > inventory) = P(Z > (inventory - mean) / std_dev)

P(demand > inventory) = P(Z > (inventory - 150) / 60)

where Z is the standard normal random variable.

We want to choose the inventory level that minimizes the expected total cost, which is the sum of the cost of holding inventory and the cost of not having enough inventory

Expected total cost = cost of holding inventory + cost of not having enough inventory

Expected total cost = (inventory * $2.00) + (P(demand > inventory) * $10.00)

To minimize this cost, we need to find the inventory level that makes the expected total cost as low as possible. We can use calculus to find the minimum expected total cost.

Taking the derivative of the expected total cost with respect to the inventory level, we get

d/d(inventory) (Expected total cost) = $2.00 - ($10.00 * (1 / sqrt(2 * pi)) * exp(-(inventory - 150)^2 / (2 * 60^2)) * (inventory - 150) / 60)

Setting this derivative equal to zero and solving for the inventory level, we get

$2.00 - ($10.00 * (1 / sqrt(2 * pi)) * exp(-(inventory - 150)^2 / (2 * 60^2)) * (inventory - 150) / 60) = 0

Simplifying this equation, we get

exp(-(inventory - 150)^2 / (2 * 60^2)) * (inventory - 150) / 60 = 0.2

Using a numerical solver or a table of values for the standard normal distribution, we can find that the inventory level that minimizes the expected total cost is approximately 174 bags.

Step 1: Corresponding sides, AB = 2 units, BC = √(13) units, AC = 3 units, A'B'= 4 units, B'C' = √(52) units, C'A' = 6 units. Step 2: scale factor of dilation is 2. Bonus: 2√(13) units.

Dilation can be performed with respect to a fixed point called the center of dilation, or with respect to a fixed line called the line of dilation. When dilation is performed with respect to a point, the distance between the center of dilation and every point on the object is multiplied by the same scale factor. When dilation is performed with respect to a line, the distance between every point on the object and the line of dilation is multiplied by the same scale factor.

Step 1: Comparing corresponding sides

AB = distance between A(2,3) and B(2,1) = 2 units

BC = distance between B(2,1) and C(5,3) = √((5-2)² + (3-1)²) = √(9+4) = √(13) units

AC = distance between A(2,3) and C(5,3) = 3 units

A'B' = distance between A'(-4,-1) and B'(-4,-5) = 4 units

B'C' = distance between B'(-4,-5) and C'(2,-1) = √((-4-2)² + (-5+1)²) = √(36+16) = √(52) units

C'A' = distance between C'(2,-1) and A'(-4,-1) = 6 units

Step 2: Finding the scale factor

To find the scale factor, we need to divide the length of each corresponding side in triangle A'B'C' by the length of the corresponding side in triangle ABC. This gives us:

Scale factor = A'B' / AB = 4/2 = 2

So, the scale factor of dilation is 2.

Bonus: Finding the length of BC and B'C'

To find the length of BC and B'C', we can use the distance formula.

The length of BC = √((5-2)² + (3-1)²) = √(13) units.

The length of B'C' = √((-4-2)² + (-5+1)²) = √(52) units.

Alternatively, we could also use the scale factor to find the length of B'C':
