Fixed costs are expenses that remain constant regardless of the level of production. The calculation of average fixed costs (AFC) is obtained by dividing the total fixed cost by the number of units produced.

AFC provides the amount per unit that the company will spend on fixed costs to produce a given quantity of output. Therefore, to calculate the average fixed cost at the Shanghai factory if the 2020 output level (= 35,000 cars annually) were maintained for ten years, we will first calculate the total fixed costs.

The formula for calculating average fixed cost (AFC) is:

Average Fixed Cost (AFC) = Total Fixed Cost / Quantity ProducedTotal Fixed Cost is obtained by multiplying the fixed cost per unit with the total number of units produced.

Total Fixed Cost (TFC) = Fixed Cost per Unit × Number of Units ProducedThe problem does not provide any information about the fixed cost per unit, which is why it cannot be calculated.

The question that can be answered by finding 10 divided by 2 11/20 is "What is the simplified value of 10 divided by 2 11/20?" and the answer is "7 43/51".

A mixed number is a representation of both a whole integer and a legal fraction. In most cases, it denotes an integer that falls between any two whole numbers. Look at the illustration; it shows a fraction that is larger than 1 but less than 2 (see the given image). Therefore, it is a composite number.

The expression "10 divided by 2 11/20" can be simplified as a mixed number or fraction as follows:

10 divided by 2 11/20 = 10 ÷ (2 + 11/20)

= 10 ÷ (40/20 + 11/20)

= 10 ÷ (51/20)

= 10 × (20/51)

= 400/51

= 7 43/51 (in mixed number form)

Therefore, the question that can be answered by finding 10 divided by 2 11/20 is "What is the simplified value of 10 divided by 2 11/20?" and the answer is "7 43/51".

Answer: The total medical bill function for Dr. Leon is given by:

c(m) = 26m + 60

During the holidays, Dr. Leon changes his total medical bill function to:

c(m) = 35m + 45

We can compare the two functions to see how they differ:

c(m) = 35m + 45 (holiday pricing)

c(m) = 26m + 60 (regular pricing)

To calculate the difference in cost between the two pricing plans, we can subtract the regular pricing from the holiday pricing:

c(m) - c(m) = (35m + 45) - (26m + 60)

= 9m - 15

Therefore, the difference in cost between the two pricing plans is 9m - 15 dollars per 20-minute session. For any given value of m, we can use this expression to calculate the difference in cost between the two pricing plans.

Step-by-step explanation:

The sample mean is approximately 23.1.

Given a confidence interval for the population mean of (16.4, 29.8), we can find the sample mean by taking the average of the lower and upper bounds.

The sample mean = (16.4 + 29.8) / 2 = 46.2 / 2 = 23.1.

Therefore, the sample mean is approximately 23.1.

The confidence interval provides a range of values within which we can be confident the population mean falls. The midpoint of the confidence interval, which is the sample mean, serves as a point estimate for the population mean.

In this case, the sample mean of 23.1 represents our best estimate for the population mean based on the given data and confidence interval.

(a) The point of intersection lies on the line passing through P and Q and is (9, -1, 9).

(b) The equation of the plane passing through the three points P(2, 0, 1), Q(0, 4, −1), and R(−1, 3, 0) is 2x + 4y + 6z = 20.

(c) The equation of the plane passing through the point P(-4, 3, 0) and containing the line with parametric equations x = 3 + 5t, y = 1 − 3t, and z = −2 + 7t is 101x + 135y + 65z = -14260.

(a)

Find the direction vector of the line by subtracting the coordinates of P from the coordinates of Q:

direction vector = Q - P = (9, -1, 9) - (1, 0, 6) = (8, -1, 3)

Substitute the coordinates of an arbitrary point on the line into the equation of the plane and solve for the parameter t:

x + y − z = 11

(1 + 8t) + (0 - t) - (6 + 3t) = 11

4t - 4 = 0

t = 1

Substitute the value of t found in step 2 into the equations for x, y, and z to get the coordinates of the point of intersection:

x = 1 + 8t = 9

y = 0 - t = -1

z = 6 + 3t = 9

So, the point of intersection is (9, -1, 9).

Check that the coordinates of the point of intersection lie on the line by substituting them into the equation for the line and verifying that the parameter t equals 1:

(9 - 1) / 8 = (-1 - 0) / (-1) = (9 - 6) / 3 = 1

Since t equals 1, the point of intersection lies on the line passing through P and Q.

(b)

Find two direction vectors for the plane by subtracting the coordinates of P from those of Q and R:

u = Q - P = (0, 4, -1) - (2, 0, 1) = (-2, 4, -2)

v = R - P = (-1, 3, 0) - (2, 0, 1) = (-3, 3, -1)

Find the normal vector of the plane by taking the cross product of the direction vectors u and v:

n = u x v = (-2, 4, -2) x (-3, 3, -1) = (2, 4, 6)

Use the point-normal form of the equation of a plane to find the equation of the plane, using any of the given points, say P:

(x - 2, y - 0, z - 1) · (2, 4, 6) = 0

2(x - 2) + 4y + 6(z - 1) = 0

2x + 4y + 6z = 20

(c)

Find two direction vectors for the plane by taking two different points on the line and subtracting their coordinates:

direction vector 1 = (8, -6, 14) - (3, 1, -2) = (5, -7, 16)

direction vector 2 = (13, -8, 21) - (3, 1, -2) = (10, -9, 23)

Note that these direction vectors are parallel to the plane because they are also parallel to the line contained within it.

Find the normal vector of the plane by taking the cross product of the direction vectors:

n = direction vector 1 x direction vector 2 = (5, -7, 16) x (10, -9, 23) = (101, 135, 65)

Use the point-normal form of the equation of a plane to find the equation of the plane, using the given point P:

(x + 4, y - 3, z) · (101, 135, 65) = 0

101(x + 4) + 135(y - 3) + 65z = 0

101x + 135y + 65z = -14260

The value of `num_different` will represent the number of times, in 10,000 trials, that two words picked uniformly at random from "Pride and Prejudice" have different lengths.

To find the number of times, in 10,000 trials, that two words picked uniformly at random from "Pride and Prejudice" have different lengths, we can use a simulation.

Here's how you can do it:

Define a function that randomly selects two words from "Pride and Prejudice" and checks if they have different lengths.
Set a counter variable to keep track of the number of times the words have different lengths.
Run a loop for 10,000 trials.
In each trial, call the function to select two words randomly.
If the lengths of the two words are different, increment the counter.

After running all the trials, the counter will hold the number of times the words had different lengths.
Print the value of the counter.

Here is a Python code snippet that demonstrates the simulation:

```python
import random

def different_lengths():
   words = ['Pride', 'and', 'Prejudice']
   word1 = random.choice(words)
   word2 = random.choice(words)
   return len(word1) != len(word2)

counter = 0

for _ in range(10000):
   if different_lengths():
       counter += 1

print

("Number of times two words had different lengths:", counter)
```

Running this simulation will give you the number of times, out of 10,000 trials,

that two words picked uniformly at random from "Pride and Prejudice" have different lengths.
