The number of ways to arrange N people with A and B separated is given by expression   N! - 2*(N-1)! .

What exactly are expressions?

In mathematics, an expression is a combination of numbers, variables, operators, and functions that are grouped together in a meaningful way. Expressions can be as simple as a single number or variable, or they can be complex and include many different elements. They are used to represent mathematical relationships and operations, and can be evaluated or simplified using mathematical rules and techniques. Examples of expressions include:

Now,

Let the two particular people be A and B.

If we place A in a spot, there are N-1 spots left for B to be placed. Once A and B are placed, there are (N-2)! ways to place the remaining people. Therefore, the number of ways to arrange N people with A and B separated is:

(N-1) * (N-2)!

Alternatively, we can find the total number of ways to arrange N people in a line (N!) and subtract the number of ways to arrange them with A and B together.

To find the number of ways to arrange N people with A and B together, we can treat A and B as a single entity, so there are (N-1)! ways to arrange the remaining people with AB together. However, A and B can be arranged in two ways (AB or BA), so we need to multiply (N-1)! by 2.

Therefore, the number of ways to arrange N people with A and B separated is:

N! - 2*(N-1)!

The best estimate for the weight of a cantaloupe is 2 kilograms (B).

A decigram is 1/10th of a gram, which would be too small of weight for a cantaloupe. 2 grams (C) is also too small for a cantaloupe as it would only be the weight of a few small seeds. 2 milligrams (D) is an extremely small weight, only suitable for a single grain of salt or a tiny insect.

Therefore, 2 kilograms (B) is the most reasonable estimate for the weight of a cantaloupe as it falls within the typical range of cantaloupe weights.

The probability of getting exactly 2 tails in 7 flips of a coin with a probability of tails being 3/4 is 189/16384 or approximately 0.0115.

We can use the binomial distribution formula to solve this problem. Let X be the number of tails that come up in 7 flips of the coin. Then X follows a binomial distribution with n = 7 and p = 3/4 (since the probability of tails is 3/4).

The probability of getting exactly 2 tails is given by:

P(X = 2) = (7 choose 2) * (3/4)^2 * (1/4)^5

= (21 * 9/16 * 1/1024)

= 189/16384

So the probability that George flips exactly 2 tails is 189/16384, or approximately 0.0115.

Answer:

3) p(2) = 22

4) k = 0

Step-by-step explanation:

Remainder theorem: If the polynomial p(x) is divided by the linear polynomial x -a then the remainder is p(a).

3)p(m) = m⁴ - 2m³ +  m² + 12m - 6

p(m) is divided by (m - 2).

m -2 = 0

m = 2. The remainder is p(2)

p(2) = 2⁴ - 2*2³ + 2² + 12*2 - 6

      = 16 - 16 + 4 + 24 - 6

      = 22

p(2) = 22

4) p(x) = 8x³ + 6x² + x + k

p(x) is divided by (2x + 3).

2x + 3 = 0

Step-by-step explanation:

Out of the total number of candies, 1/2 of the pink candies are round.

To find the fraction of the candies that are pink and round, we need to multiply the fractions representing the proportion of pink candies and the proportion of round candies among the pink candies:

pink candies = 5/6

round candies among the pink ones = 1/5

Therefore, the fraction of candies that are pink and round is:

(5/6) x (1/2) x 1/5 = 1/12

So, 1/12 of the candies are pink and round.

A zero vertical asymptote removable discontinuity means that there is a zero of the function at the input value where the vertical asymptote would occur,

A zero of a function occurs when the value of the function is zero. A vertical asymptote of a function occurs when the value of the function becomes unbounded (either positive or negative) as the input approaches a certain value.

A removable discontinuity of a function occurs when there is a hole in the graph of the function at a certain input value, but the function can be made continuous at that point by defining its value at that input.

In the case of a zero vertical asymptote removable discontinuity, this means that there is a zero of the function at the input value where the vertical asymptote would occur, and the function can be made continuous at that input value by defining its value to be the value of the function at that input.

We can use the standard normal distribution to solve this problem by standardizing the score.

z = (x - mu) / sigma

Where:

x = 70 (score we are interested in)

mu = 60 (mean score)

sigma = 7 (standard deviation)

z = (70 - 60) / 7 = 1.43

Using a standard normal distribution table or calculator, we can find the probability that z is greater than 1.43. The probability is approximately 0.0764.

Therefore, the probability that a randomly selected student scored more than 70 on the exam is 0.0764 (or about 7.64%).

Step-by-step explanation:

The surface area of a rectangular prism can be found by adding the areas of all six of its faces.

In this case, the rectangular prism has side lengths of 3, 6, and 12 feet. So, its faces are:

Top and bottom faces: Each of these faces is a rectangle with side lengths of 3 feet and 6 feet. Therefore, the area of each of these faces is 3 ft * 6 ft = 18 ft². Since there are two of these faces, their combined area is 2 * 18 ft² = 36 ft².

Front and back faces: Each of these faces is a rectangle with side lengths of 3 feet and 12 feet. Therefore, the area of each of these faces is 3 ft * 12 ft = 36 ft². Since there are two of these faces, their combined area is 2 * 36 ft² = 72 ft².

Side faces: Each of these faces is a rectangle with side lengths of 6 feet and 12 feet. Therefore, the area of each of these faces is 6 ft * 12 ft = 72 ft². Since there are two of these faces, their combined area is 2 * 72 ft² = 144 ft².

To find the total surface area, we add the areas of all six faces:

Total surface area = 36 ft² + 72 ft² + 144 ft²

Total surface area = 252 ft²

Therefore, the surface area of the rectangular prism is 252 square feet.

Answer:

Step-by-step explanation:

12*3*2= 72 because there are two rectangles with the same length.

6*3*2= 36 because there are two widths with the same area.

6*12*2= 144 because there are a top and bottom with the same area.

72+36+144= 252

Mean absolute deviation (MAD) is sometimes considered a better approach to handle outliers in a data set than standard deviation because it is less sensitive to extreme values.

The reason for this is that MAD uses absolute differences between each data point and the median of the data set, rather than the squared differences used by standard deviation.

In a data set with extreme values, such as outliers, the squared differences used by standard deviation can significantly inflate the value, leading to a higher estimate of the overall variability in the data. MAD, on the other hand, uses absolute differences, which are not affected by the sign of the difference and thus are less affected by extreme values. Therefore, MAD can be a better measure of variability in a data set that includes outliers.

However, it is important to note that MAD also has some limitations. It is less widely used and less familiar to many analysts than standard deviation, and it has a more complex formula that can be harder to interpret. Additionally, MAD is not as efficient as standard deviation when the underlying distribution is normal, meaning it requires a larger sample size to achieve the same level of precision as standard deviation. Ultimately, the choice between MAD and standard deviation depends on the specific characteristics of the data set and the goals of the analysis.

Therefore, the inverse of f(x) is not a function, as it fails the vertical line test.

One output is produced for one input by a function, a form of rule. The formula y=x2 serves as an illustration of this. A single output for y results from any input for x. Given that x is the input value, it is appropriate to say that y is a function of x.

We can determine if the inverse of f(x) = 8x² + 27 is a function by finding the inverse and checking if it passes the vertical line test.

To find the inverse, we first replace f(x) with y:

y = 8x² + 27

Next, we swap the roles of x and y:

x = 8y² + 27

Solving for y gives:

8y² = x - 27

y² = (x - 27)/8

y = ±√((x - 27)/8)

Notice that we have a ± sign in front of the square root, which means that for each x value, we have two possible y values.

Therefore, the inverse of f(x) is not a function, as it fails the vertical line test.
