The volume of air added to the balloon is approximately 386/3 cubic units.

To find the volume of air added to the balloon, we can use the formula for the volume of a sphere: V = (4/3)πr³.

First, we need to find the radius of the balloon before and after inflation. The formula for the circumference of a sphere is C = 2πr.

Given that the initial circumference is about 14 inches, we can solve for the initial radius:
14 = 2πr
r ≈ 14/(2π) ≈ 7/(π)

Similarly, for the final circumference of about 18 inches:
18 = 2πr
r ≈ 18/(2π) ≈ 9/(π)

Now that we have the initial and final radii, we can calculate the initial and final volumes:
Initial volume = (4/3)π(7/(π))³ = (4/3)π(343/(π³)) ≈ 343/3 cubic units
Final volume = (4/3)π(9/(π))³ = (4/3)π(729/(π³)) ≈ 729/3 cubic units

To find the volume of air added, we subtract the initial volume from the final volume:
Volume of air added = Final volume - Initial volume = (729/3) - (343/3) = 386/3 cubic units.

So, approximately 386/3 cubic units of air was added to the balloon.
The volume of air added to the balloon is approximately 386/3 cubic units.

To determine the number of ways the ant can move to the bottom left corner of the 4x6 checkerboard in exactly 10 moves, we can approach this problem using combinatorics and counting techniques.

Let's represent the ant's movements as a sequence of "U" (up), "D" (down), "L" (left), and "R" (right) corresponding to the directions the ant can move. Since the ant needs to reach the bottom left corner in exactly 10 moves, the sequence will consist of 10 characters.

Now, let's count the number of valid sequences. To reach the bottom left corner, the ant needs to move down six times and left four times. Therefore, we need to find the number of different arrangements of six "D" and four "L" in the sequence of 10 moves.

This can be calculated using combinations (binomial coefficients). The formula for combinations is:

C(n, k) = n! / (k! * (n - k)!)

In this case, we need to calculate C(10, 4) since we are selecting 4 positions for "L" from a total of 10 positions.

C(10, 4) = 10! / (4! * (10 - 4)!)

        = 10! / (4! * 6!)

        = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)

The volume of the rectangular prism is 1435.

To find the volume of the rectangular prism, we need to consider the given information that the sum of its volume, total surface area, and the sum of the lengths of all its edges is equal to 2015. By analyzing the properties of a rectangular prism, we can determine the possible combinations of side lengths that satisfy the given condition.

Let's denote the side lengths of the rectangular prism as a, b, and c. The volume of a rectangular prism is given by V = a * b * c, the total surface area is given by A = 2(ab + ac + bc), and the sum of the lengths of all the edges is given by E = 4(a + b + c).

According to the problem statement, we have the equation V + A + E = 2015. Substituting the formulas for V, A, and E, we get:

a * b * c + 2(ab + ac + bc) + 4(a + b + c) = 2015.

By rearranging the equation, we have:

abc + 2ab + 2ac + 2bc + 4a + 4b + 4c = 2015.

Factoring out common terms, we get:

(a + 2)(b + 2)(c + 2) = 2015 + 8 = 2023.

Now, we need to analyze the factors of 2023 to find the possible combinations of side lengths. The factors of 2023 are 1, 7, 17, and 119. We can write (a + 2), (b + 2), and (c + 2) as these factors.

By examining the factors, we find that the combination (a + 2) = 1, (b + 2) = 7, and (c + 2) = 289 satisfies the condition. Solving these equations, we get a = -1, b = 5, and c = 287.

Since the lengths of a rectangular prism cannot be negative, we discard the solution with a = -1. Thus, the valid solution is a = 1, b = 5, and c = 287.

Finally, we can calculate the volume using the formula V = a * b * c:

V = 1 * 5 * 287 = 1435.

Therefore, the volume of the rectangular prism is 1435.

Error rate refers to the frequency or proportion of errors made in a particular context or process. It is commonly used in various fields such as statistics, computer science, and quality control.

To find the error rate for the training subset, we can use the fact that the average error rate is 0.06.

Let's denote the error rate for the training subset as E_train. We can express the average error rate as:

average error rate = (error rate for training subset + error rate for test subset) / 2

0.06 = (E_train + error rate for test subset) / 2

Multiplying both sides of the equation by 2, we get:

0.12 = E_train + error rate for test subset

The difference between the largest and smallest number of dimes that could be in the bank is 100.

Let's assume the number of nickels in the piggy bank is N, the number of dimes is D, and the number of quarters is Q.

From the given information, we can form two equations based on the number of coins and the total value:

Equation 1: N + D + Q = 100 (total number of coins)

Equation 2: 0.05N + 0.10D + 0.25Q = 8.35 (total value in dollars)

Now, let's determine the range for the number of dimes, D.

To find the smallest number of dimes, we maximize the number of nickels and quarters, which minimizes the number of dimes. Let's assume all remaining coins (100 - D) are nickels:

Equation 1: D + Q = 100 - N

Equation 2: 0.10D + 0.25Q = 8.35 - 0.05N

Since we want to minimize D, let's consider the maximum values for N and Q. Assuming all remaining coins are nickels, we have N = 100 - D - Q.

Plugging in these values, we get:

0.10D + 0.25Q = 8.35 - 0.05(100 - D - Q)

0.10D + 0.25Q = 8.35 - 5 + 0.05D + 0.05Q

0.05D + 0.20Q = 3.35

To simplify, we multiply the equation by 20:

D + 4Q = 67

The largest value for Q would be when D = 0. Therefore, if we assume all remaining coins are quarters, we have:

D = 0

Q = (100 - D) = 100

So, the largest number of quarters is 100, and the largest number of dimes is 0.

To find the largest value for D, we maximize the number of dimes. Assuming all remaining coins are nickels:

N = 100 - D - Q

Plugging this into Equation 2:

0.10D + 0.25Q = 8.35 - 0.05(100 - D - Q)

0.10D + 0.25Q = 8.35 - 5 + 0.05D + 0.05Q

0.05D + 0.20Q = 3.35

Multiplying by 20:

D + 4Q = 67

The smallest value for Q would be when D = 100. Therefore, if we assume all remaining coins are quarters, we have:

D = 100

Q = (100 - D) = 0

So, the smallest number of quarters is 0, and the smallest number of dimes is 100.

The difference between the largest and smallest number of dimes is:

100 (largest) - 0 (smallest) = 100.

Therefore, the difference between the largest and smallest number of dimes that could be in the bank is 100.

To compute the probability using the normal distribution, you would calculate P(X > a - 0.5), where a is the desired upper value for the binomial random variable X.

To approximate the upper probability P(X ≥ a) for a binomial random variable X using the normal probability distribution, you can use the continuity correction. This means that you approximate the discrete binomial distribution with a continuous normal distribution.

The continuity correction adjusts the boundaries for the normal distribution to account for the discrete nature of the binomial distribution. When approximating the upper probability, you adjust the boundary to X > a - 0.5. This adjustment helps account for the fact that the binomial distribution takes only integer values, while the normal distribution is continuous.

Therefore, to compute the probability using the normal distribution, you would calculate P(X > a - 0.5), where a is the desired upper value for the binomial random variable X.

Comparing the total areas, we find that the second neighbor's party has more pizza in terms of area, with a total of 324π square inches compared to the first neighbor's party, which has a total of 320π square inches.

To determine which party has more pizza in terms of area, we need to calculate the total area of pizzas ordered by each neighbor.

First, let's calculate the area of a large pizza with a diameter of 16 inches. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. The radius of a 16-inch diameter pizza is half of the diameter, which is 8 inches.

So, the area of each large pizza is A = π(8 inches) ^2 = 64π square inches.

The first neighbor ordered 5 large pizzas, so the total area of pizzas for their party is 5 * 64π = 320π square inches.

Next, let's calculate the area of a small pizza with a diameter of 12 inches. Using the same formula, the radius of a 12-inch diameter pizza is 6 inches.

Thus, the area of each small pizza is A = π(6 inches)^2 = 36π square inches.

The second neighbor ordered 9 small pizzas, so the total area of pizzas for their party is 9 * 36π = 324π square inches.

Comparing the total areas, we find that the second neighbor's party has more pizza in terms of area, with a total of 324π square inches compared to the first neighbor's party, which has a total of 320π square inches.

The distributions made to Miley in 2020 are taxed as follows:

Distributions up to the AAA balance ($159,000) are tax-free returns of capital.

Distributions exceeding the AAA balance are not subject to immediate taxation since the corporation reported $0 taxable income or loss in 2020.

However, the accumulated E&P of $457,500 may have future tax implications.

To determine how the distributions are taxed to Miley, we need to consider the following components: basis in S corporation stock, accumulated adjustments account (AAA) balance, and accumulated earnings and profits (E&P).

Accumulated Earnings and Profits (E&P):

The corporation has accumulated E&P from prior C corporation years totaling $457,500. E&P represents the taxable earnings and profits that have not been distributed or previously taxed to the shareholders.

Now, let's analyze how the distributions are taxed to Miley based on the given information:

a. Distributions up to the AAA balance ($159,000):

If the distributions made to Miley do not exceed the AAA balance, they are considered tax-free returns of capital. In this scenario, Miley received distributions of $84,500 and $63,000, which amount to a total of $147,500. Since this total is less than the AAA balance of $159,000, the entire amount is considered a tax-free return of capital and is not subject to immediate taxation.

b. Distributions exceeding the AAA balance:

Any distributions made to Miley beyond the AAA balance are treated as taxable dividends to the extent of the corporation's accumulated E&P. In this case, since the corporation reported $0 taxable income or loss in 2020, there is no additional taxable income from the corporation.

However, it's important to note that the accumulated E&P of $457,500 may have tax implications in the future, especially if the corporation resumes C corporation status or engages in certain transactions that trigger recognition of the accumulated E&P

The height of the tank is 1.5 meters.

To find the height of the tank, we can use the formula for the volume of a rectangular tank, which is given by V = lwh,

where V is the volume, l is the length, w is the width, and h is the height.

Given that the area of the base is 2.4 square meters, we can find the length and width by taking the square root of the area since the base is rectangular.

Let's denote the length as L and the width as W.

√(lw) = √2.4

To find the capacity of the tank, we multiply the area of the base by the height:

V = 2.4h

We are given that the capacity is 3.6 cubic meters, so we can set up the equation:

2.4h = 3.6

To find the height, we divide both sides of the equation by 2.4:

h = 3.6 / 2.4 = 1.5

Therefore, the height of the tank is 1.5 meters.

It's important to note that the units for the area, volume, and height should be consistent.

In this case, since the area is given in square meters and the volume in cubic meters, the height is also in meters to maintain consistency.

The bicycle is traveling at a speed of 13 m/s.

In one rotation of the wheel of the bicycle, the distance covered by the bicycle = the circumference of the wheel of the bicycle

Now, according to the question,

Number of rotations of the wheel of the bicycle in 1 minute = 260

∴ Number of rotations of the wheel in 1 second = 260 ÷ 60

                                                                               = 13/3

∴ Distance traveled by bicycle due to the rotation of the wheel in 1 minute = 260 × circumference of the wheel of the bicycle

Or, distance traveled by bicycle in 1 second = 13/3 × circumference of the wheel of the bicycle.

                                                                         = 13/3 × 3 m

                                                                         = 13 m

Hence, the bicycle is traveling at a speed of 13 m/s.

These values represent the mean and standard deviation for the chi-square distribution with 18 degrees of freedom.

In a chi-square distribution, the population mean (μ) and standard deviation (σ) depend on the degrees of freedom (df).

For a chi-square distribution with k degrees of freedom, the mean (μ) is given by k and the standard deviation (σ) is equal to the square root of 2k.

In this case, the number of degrees of freedom is given as 18. Therefore, the population mean (μ) for the chi-square distribution is 18, and the standard deviation (σ) is the square root of 2 times 18, which simplifies to √36, resulting in a standard deviation of 6.

To summarize:

Population mean (μ) = 18

Standard deviation (σ) = 6

These values represent the mean and standard deviation for the chi-square distribution with 18 degrees of freedom.

A system of inequalities can have zero solutions, one solution, or infinitely many solutions, depending on the specific conditions and constraints of the inequalities involved.

A system of inequalities can have different numbers of solutions depending on the specific equations involved. Here are the possibilities:

1. No Solution: It's possible for a system of inequalities to have no solution, meaning there is no set of values that satisfies all the inequalities simultaneously. This happens when the inequalities are contradictory or when their solution sets don't overlap.

2. One Solution: In some cases, a system of inequalities can have a unique solution, where there is only one set of values that satisfies all the inequalities. This happens when the solution set for each inequality overlaps with the others in a specific way.

3. Infinite Solutions: Another possibility is that a system of inequalities can have infinitely many solutions. This occurs when the solution sets for the inequalities overlap completely or when the inequalities are equivalent.

Remember, the number of solutions can vary depending on the specific system of inequalities, so it's important to analyze each case individually.

The sum of the arithmetic sequence is -468 (option D).

To find the sum of an arithmetic sequence, we can use the formula:

Sum = (n/2) * (first term + last term)

In this case, the first term of the sequence is 4, and the common difference between consecutive terms is -3. We need to find the last term of the sequence.

To find the last term, we can use the formula for the nth term of an arithmetic sequence:

last term = first term + (n - 1) * common difference

In this case, the last term is -56. We can use this information to find the number of terms (n) in the sequence:

-56 = 4 + (n - 1) * (-3)

-56 = 4 - 3n + 3

-56 - 4 + 3 = -3n

-53 = -3n

n = -53 / -3 = 17.67

Since the number of terms should be a whole number, we round up to the nearest whole number and get n = 18.

Now, we can find the sum of the arithmetic sequence:

Sum = (18/2) * (4 + (-56))

Sum = 9 * (-52)

Sum = -468

Therefore, the sum of the arithmetic sequence is -468 (option D).

The asymptotes of P are the vertical lines x = -5 and x = 3. When the rectangle is close to the asymptotes, it will become longer and thinner.

To determine the asymptotes of a rectangle's perimeter (P), we need to understand what an asymptote represents in this context. An asymptote is a line that a graph approaches but does not intersect or cross. In the case of the rectangle's perimeter, we can consider the length and width of the rectangle as variables.

Asymptotes of P:

1. When the length of the rectangle approaches infinity or negative infinity while keeping the width constant, the perimeter P will approach infinity. Similarly, when the length approaches negative infinity or infinity, P will also approach infinity.

  Mathematically, this can be represented as:

  lim(length → ±∞) P = ∞

2. Similarly, when the width of the rectangle approaches infinity or negative infinity while keeping the length constant, the perimeter P will also approach infinity. Conversely, when the width approaches negative infinity or infinity, P will approach infinity.

  Mathematically, this can be represented as:

  lim(width → ±∞) P = ∞

Therefore, the asymptotes of the rectangle's perimeter P are the lines representing the infinite values of length and width. When a rectangle's length or width is close to the asymptotes, the rectangle becomes extremely elongated or stretched. It may appear more like a line rather than a typical rectangle. The sides of the rectangle will be very long, while the opposite sides will be extremely short or close to zero.

In Performance Task 1, where the rectangle's area (A) was the focus, there were no asymptotes to consider. The area of a rectangle can continue to increase or decrease without bounds as the length or width grows or shrinks, respectively. There is no specific line or value that the area approaches without crossing or intersecting, as opposed to the concept of asymptotes in the perimeter.
