List all the permutations of {a, b,c}.

Thus, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

To find all possible subsets of the set a = {a, b, c, d, e} using both elements a and b, we need to consider all the possible combinations of these two elements with the remaining elements in the set.

There are three possible subsets that we can create using both elements a and b:

1. {a, b} - This is the subset that contains only the elements a and b.
2. {a, b, c} - This subset contains the elements a and b, along with the third element c.
3. {a, b, d} - This subset contains the elements a and b, along with the fourth element d.

Note that we cannot create any more subsets using both elements a and b because we have already considered all the possible combinations with the remaining elements in the set.

In summary, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

The measure of angle C in triangle CDE is 9 degrees

To find the measure of angle C in triangle CDE, we need to solve the given equation.

The measure of angle C is (x - 4) degrees.

In the triangle, the sum of the measures of all three angles must be equal to 180 degrees (since it is a triangle). So we can set up the equation:

(x - 4) + (11x - 11) + (x + 13) = 180

Simplifying the equation:

2x - 4 + 11x - 11 + x + 13 = 180

14x - 2 = 180

14x = 182

x = 13

Substituting x = 13 into the equation for angle C:

(x - 4) = (13 - 4) = 9

Therefore, the measure of angle C is 9 degrees.

In summary, the measure of angle C in triangle CDE is 9 degrees. To find this value, we set up an equation using the sum of the measures of all three angles in a triangle, and then solved for x by simplifying and rearranging the equation. Substituting the value of x into the equation for angle C gives us the final answer of 9 degrees.

The possible numbers of lawns the company could have mowed are 12 and 80.

A landscaper earns $30 for each lawn her company mows, but she pays $210 per day in salary to her employees. If her company made more than $150 profit from mowing lawns in a 7-day week, we can use the inequality equation below to solve for the possible numbers of lawns the company could have mowed:7(30x) - 210(7) > 150where x is the number of lawns the company mowed. The left side of the inequality represents the total income the company earned from mowing lawns, while the right side represents the total cost, which is the weekly salary plus the $150 profit we want to exceed. Simplifying the inequality, we get:210x > 5402100 > x. Since the number of lawns has to be a whole number, the possible numbers of lawns the company could have mowed are 12 and 80.

The equation of the plane that passes through the point (1, −1, 1) and contains the line with symmetric equations x = 2y = 4z is :

y - 2z = -3/2.

To find the equation of the plane that passes through the point (1, −1, 1) and contains the line with symmetric equations x = 2y = 4z, we need to first find the direction vector of the line.

Since x = 2y = 4z, we can write this as y = x/2 and z = x/4. Letting x = t, we can parameterize the line as:

x = t

y = t/2

z = t/4

So the direction vector of the line is <1, 1/2, 1/4>.

Next, we can use the point-normal form of the equation of a plane to find the equation of the plane. The point-normal form is:

n · (r - r0) = 0

where:

n is the normal vector of the plane

r is a point on the plane

r0 is a known point on the plane

We know that the plane passes through the point (1, −1, 1), so we can set r0 = <1, -1, 1>. We also know that the direction vector of the line is parallel to the plane, so the normal vector of the plane is perpendicular to the direction vector of the line.

To find the normal vector of the plane, we can take the cross product of the direction vector of the line and another vector that is not parallel to it. One such vector is the vector <1, 0, 0>. So the normal vector of the plane is:

<1, 1/2, 1/4> × <1, 0, 0> = <0, 1/4, -1/2>

Now we can write the equation of the plane using the point-normal form:

<0, 1/4, -1/2> · (<x, y, z> - <1, -1, 1>) = 0

Expanding this, we get:

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

Simplifying, we get:

y - 2z = -3/2

So the equation of the plane is y - 2z = -3/2.

The total number of unique positions of n identical rooks on an n by n chessboard such that exactly one pair of rooks can attack each other is (n - 1)^2 * (n - 1)! or (n - 1) * (n - 1)! * (n - 1).

To find the number of unique positions of n identical rooks on an n by n chessboard such that exactly one pair of rooks can attack each other, we need to consider the number of empty rows and columns.

First, let's consider the number of empty rows. Since exactly one pair of rooks can attack each other, we know that there can be at most one rook in each row. This means that there are n rows with at most one rook each, leaving (n - 1) empty rows.

Next, let's consider the number of empty columns. Again, since exactly one pair of rooks can attack each other, there can be at most one rook in each column. This means that there are n columns with at most one rook each, leaving (n - 1) empty columns.

Now, we can use combinations to find the number of ways to choose one row and one column for the pair of rooks that can attack each other. There are (n - 1) options for the row and (n - 1) options for the column, giving us a total of (n - 1) * (n - 1) = (n - 1)^2 possible combinations.

Finally, we need to multiply this by the number of ways to place the remaining rooks in the empty rows and columns. Since each rook can be placed in any of the empty rows or columns, there are (n - 1)! ways to arrange the remaining rooks.

Therefore, the total number of unique positions of n identical rooks on an n by n chessboard such that exactly one pair of rooks can attack each other is (n - 1)^2 * (n - 1)! or (n - 1) * (n - 1)! * (n - 1).

Mrs. Falkener has written a company report every 3 months for the last 6 years, resulting in a total of 24 reports. Among these reports, 2/3 of them show the company earning more money than it spends. Therefore, 1/3 of the reports, or 8 reports, show the company spending more money than it earns.

In 6 years, there are 12 quarters since there are 4 quarters in a year. Mrs. Falkener has written a company report every 3 months, which means there are 12 * 3 = 36 periods in total. However, since each report covers a 3-month period, the total number of reports is 36 / 3 = 12.

Given that 2/3 of the reports show the company earning more money than it spends, we can calculate the number of reports showing the company spending more money than it earns. Since 2/3 of the reports represent the earnings being greater, the remaining 1/3 represents the expenses being greater. Therefore, 1/3 of 12 reports is 12 * (1/3) = 4 reports.

In conclusion, among the 24 company reports written by Mrs. Falkener in the last 6 years, 2/3 of them, or 16 reports, show the company earning more money than it spends. The remaining 1/3, or 8 reports, show the company spending more money than it earns.

Without additional information, it is difficult to provide a specific answer. However, if we assume that the total waiting time follows a probability distribution such as the exponential distribution, we can calculate the probability as follows:

Let X be the total waiting time. Then, X can be expressed as the sum of two independent waiting times, X1 and X2.

Let f(x) be the probability density function of X. Then, we can use the cumulative distribution function (CDF) of X to calculate the probability that the total waiting time is either less than 2 min or more than 7 min.

P(X < 2 or X > 7) = P(X < 2) + P(X > 7)

Using the properties of the CDF, we can express this probability as:

P(X < 2 or X > 7) = 1 - P(2 ≤ X ≤ 7)

Next, we can use the fact that the waiting times are independent and identically distributed to express the probability in terms of the CDF of X1:

P(2 ≤ X ≤ 7) = ∫2^7 ∫0^(7-x1) f(x1) f(x2) dx2 dx1

If we assume that the waiting times follow the exponential distribution with parameter λ, then the probability density function is given by:

f(x) = λe^(-λx)

Substituting this into the above expression and evaluating the integral, we get:

P(2 ≤ X ≤ 7) = 1 - e^(-5λ) - 5λe^(-5λ)

Therefore, the probability that the total waiting time is either less than 2 min or more than 7 min is:

P(X < 2 or X > 7) = 1 - (1 - e^(-5λ) - 5λe^(-5λ)) = e^(-5λ) + 5λe^(-5λ)

Again, this is based on the assumption that the waiting times follow the exponential distribution with parameter λ.

If a different distribution is assumed, the probability calculation would be different.

The researcher needs at least 67 participants in the sample size to adequately conduct a study to estimate the population mean to within 5 points at a 90% level of confidence. The sample size is an essential part of any research study. The sample size is the number of participants or observations in the study.

To estimate the sample size, we should use the following formula:

N = (Z² * s²) / E²

Where: N = Sample Size, Z = Z-score (z-score for a 90% confidence level is 1.645), s = Standard deviation, E = Margin of error (We have 5 points or 0.05 in decimal form)

Now, we will calculate the Standard deviation which is the square root of the variance. The variance is obtained by dividing the population range by 4. It's 80/4 = 20s = √20 = 4.47

Plugging in these values to the above formula: N = (1.645² * 4.47²) / 0.05²

N = 66.7 ≈ 67

Therefore, the researcher needs at least 67 participants in the sample size to adequately conduct a study to estimate the population mean to within 5 points at a 90% level of confidence. The sample size is an essential part of any research study. The sample size is the number of participants or observations in the study. A sample is taken from the population because it's usually impossible to collect data from the entire population. The sample size must be adequately determined to produce accurate results and avoid errors that may affect the study's validity. A larger sample size is more representative of the population, and it minimizes the effect of random errors. However, a sample that is too large can lead to waste of resources, time, and money. Therefore, researchers determine the sample size required based on various factors, including the population's size, variability of the data, the level of confidence desired, and the margin of error.

We can then use this information to solve the problem as follows:Let the number of fence segments be n.Each segment is 8 pm = 1/3 day long.The total length of the fence is 3000 feet.So, the length of one segment of the fence = (3000/n) feet.There are 10 posts per segment.

So, the number of posts in one segment of the fence = 10 x (1/3) = (10/3) posts.Since there is one post at the start and end of each segment, the total number of posts in one segment of the fence = (10/3) + 2 = (16/3) posts.

So, the total number of posts in the fence, n = Total length of the fence / Length of one segmentNumber of segments = n = 3000 / (3000/n)Number of segments = n = (3000 * n) / 3000Number of segments = n = n

Step-by-step explanation:

The MAD is approximately 15.4. The MAD tells us that on average, the forecast errors are about 15.4 units away from the mean forecast error.

The Mean Absolute Deviation (MAD) is a measure of the variability of a set of data. It represents the average distance of the data points from the mean of the data set.

To calculate the MAD, we need to first find the mean of the forecast errors. The mean is the sum of the forecast errors divided by the number of errors:

Mean = (-22 - 10 + 15)/3 = -4/3

Next, we find the absolute deviation of each error by subtracting the mean from each error and taking the absolute value:

|-22 - (-4/3)| = 64/3

|-10 - (-4/3)| = 26/3

|15 - (-4/3)| = 49/3

Then, we find the average of these absolute deviations to get the MAD:

MAD = (64/3 + 26/3 + 49/3)/3 = 139/9

Therefore, the MAD is approximately 15.4. The MAD tells us that on average, the forecast errors are about 15.4 units away from the mean forecast error.

The rectangular equation given is x + 7√(x² + y²) = x² + y², which can be converted to the polar equation r = 7 - cos(θ).

Using the trigonometric identity cos(θ) = x/r, we can write:

r = 7 - x/r

Multiplying both sides by r, we get:

r² = 7r - x

Using the polar to rectangular conversion formulae x = r cos(θ) and y = r sin(θ), we can express r in terms of x and y:

r² = x² + y²

Substituting r² = x² + y² into the previous equation, we get:

x² + y² = 7r - x

Substituting cos(θ) = x/r, we can write:

x = r cos(θ)

Substituting this into the previous equation, we get:

x² + y² = 7r - r cos(θ)

Simplifying, we get:

x² + y² = 7√(x² + y²) - x

The area of the shaded region is 0.785 square units.

To find the shaded area between the circle and the square.

To begin, let's find the area of the square. A square with sides of 1.2 units has an area of 1.44 square units.

Now let's find the area of the circle. The radius of the circle is half the diameter, which is 1.75 units. The area of the circle is πr² = π(1.75)² ≈ 9.616 square units.

Now, we need to find the area of the shaded region by subtracting the area of the square from the area of the circle: 9.616 - 1.44 = 8.176 square units.

However, this is not the shaded region as the square is intersecting the circle. If we subtract the area of the unshaded region from the total area of the shaded region, we will get the area of the shaded region.

The unshaded area is the area of the square not covered by the circle, which is 0.435 square units. Thus, the area of the shaded region is

9.616 - 1.44 - 0.435 = 7.741 square units.

The distance traveled by the car when the tire makes one complete turn is 56.52 inches. The distance traveled by the car is equivalent to the wheel's circumference.

Given that the diameter of a wheel is 18 inches and the value of Pi is 3.14. To find the distance traveled by the car when the tire makes one complete turn, we need to find the circumference of the wheel.

Circumference of a wheel = πd, where d is the diameter of the wheel. Substituting the given values in the above formula, we get:

Circumference of a wheel = πd

                                 = 3.14 × 18

                                 = 56.52 inches.

Therefore, the distance traveled by the car when the tire makes one complete turn is 56.52 inches. When a wheel rolls over a surface, it creates a circular path. The length of this circular path is known as the wheel's circumference. It is directly proportional to the diameter of the wheel.

A larger diameter wheel covers a larger distance in one complete turn. Similarly, a smaller diameter wheel covers a smaller distance in one complete turn. Therefore, to find the distance covered by a car when the tire makes one complete turn, we need to find the wheel's circumference. The formula to find the wheel's circumference is πd, where d is the diameter of the wheel. The value of Pi is generally considered as 3.14.

The wheel's circumference is 56.52 inches. Therefore, the distance traveled by the car when the tire makes one complete turn is 56.52 inches.

the probability of not being the victim of the theft involving the bicycle, if the victim of the theft is randomly selected, is 0.961.

According to the given data, it is given that there was a 3.9% probability of theft involving a bicycle in 2002. Thus, the probability of not being the victim of the theft involving the bicycle can be calculated by the complement of the probability of being the victim of the theft involving the bicycle.

The formula for calculating the probability of the complement is:

P(A') = 1 - P(A)

Where P(A) represents the probability of the event A, and P(A') represents the probability of the complement of event A.

Thus, the probability of not being the victim of the theft involving the bicycle can be calculated as:

P(not being the victim of the theft involving the bicycle) = 1 - P(the victim of the theft involving the bicycle)

Now, substituting the value of P(the victim of the theft involving the bicycle) = 3.9% = 0.039 in the above formula, we get:

P(not being the victim of the theft involving the bicycle) = 1 - 0.039P(not being the victim of the theft involving the bicycle) = 0.961

Therefore, the probability that the randomly selected victim was not the victim of bicycle theft is 0.961 Thus, the probability of not being the victim of the theft involving the bicycle, if the victim of the theft is randomly selected, is 0.961.

a. if the curve is increasing or remains constant between the two maxima, there will not be a relative minimum point. b. A curve to have an inflection point without having any relative extreme points.

(a) If a smooth curve has two relative maximum points, it may or may not have a relative minimum point. This is because the presence of a relative minimum point depends on the behavior of the curve between the two relative maxima. If the curve is decreasing between the two maxima, it will have a relative minimum point. However, if the curve is increasing or remains constant between the two maxima, there will not be a relative minimum point. (b) If a smooth curve has two relative extreme points, it may or may not have an inflection point. The presence of an inflection point depends on the behavior of the curve between the two relative extreme points. If the curve changes concavity between the two extremes, it will have an inflection point. However, if the curve maintains the same concavity or does not change direction, it will not have an inflection point. It is also possible for a curve to have an inflection point without having any relative extreme points.
