given a circle that is divided into n identical sectors, and we have k different colors to paint it. how many ways can we paint it under the condition that no adjacent pieces have the same color?

Answers

Answer 1

The number of ways we can paint is g(nk)=1/n ∑d | n ϕ(d) ((k−1)^n/d +(−1)^n/d (k−1))

Given,

Whether your circle has named sectors (i.e., is fixed) or lacks labels will determine this (i.e. is free).

In the first scenario, inclusion-exclusion can be used to create sets Ai,j of colorings with adjacent sectors I and j having the same color. Next, generally

|Ai1,j1∩⋯∩Air,jr|={(k^n − r r<n) ( k r=n)

And inclusion-exclusion yields f(n, k), the number of sectors that are colored with k colors that are not related to any of Ai, j (i.e., do not have similar adjacent colors):

f(n, k) = ∑r = 0 n−1 (−1)^r (n, r) k^n - r + (−1)^n (n, n)k

And the result of adding and subtracting (1) is:

⟹f(n, k) = ∑r = 0 n−1 (−1)^r (n, r) k^n−r + (−1)^n (n, n)k = (k−1)^n + (−1)^n (k−1)

That is your response to the fixed circle.

Burnside's Lemma, which generates the cycle index of a combinatorial necklace, must be applied if you want the solution for a free circle (assuming the symmetries involved are merely rotations):

Z(Cn) = 1n∑d∣nϕ(d)an/dd

Then, n/d cycles with dN sectors in each cycle, an/dd permutations representing rotations of sectors, and (d) is the Euler Totient Function[4] are used.

Since each cycle must contain a single color from the n available options, we must swap out an/dd with f(n/d, k), resulting in a total of g(n, k) free colorings for n>1*:

g(n, k)=1/n ∑d∣n ϕ(d) ((k−1)^n/d +(−1)^n/d (k−1))

mia has a certain amount of money. if she buys $4$ pens and $1$ pencil, she will have $\$5$ left over. if she buys $2$ pens and $2$ pencils, she will have $\$3$ left over. if edward arrives with the same amount of money as mia, together they can buy $7$ pens and $4$ pencils and spend all their money. if $a$ is the cost of one pen and $b$ is the cost of one pencil, compute the ordered pair $(a,b)$.

Answers

If 2 is the cost of one pen and 6 is the cost of one pencil, compute the ordered pair (2,6)

When Mia buys 4 pens and 1 pencil, she has $5 left; the number of dollars she starts with is 4a+b+5.

When she buys 2 pens and 2 pencils, she has $3 left; the number of dollars she starts with is 2a+2b+3.

Since those two expressions represent the same number, set them equal to each other and simplify to get an equation in a and b.

4a+b+5=2a+2b+3

2a-b=-2 [1]

They can purchase 7 pens and 4 pencils with their entire budget if Edward shows up with the same amount of money that Mia did.

The two of them have twice as much money as Mia did in the beginning, and they can buy 7 pens and 4 pencils with the money they have left over. To get a second equation in a and b, write an equation that says that and simplify it.

7a+4b = 8a+2b+10

a-2b=-10 [2]

solving both the equations 1 and 2:

2a-b = -2 - [1]

a-2b = -10 -[2]

a = 2 , b= 6

how many pounds does a 1.98 liter bottle of water weigh on earth? (ignore the weight of the empty plastic bottle, and assume 3 significant digits).

Answers

The amount of 198 liters of water weights 4.45 Pound force on the earth.

The density of the water is 1 kg/L.

It means that 1 L of water has 1 kg of water.

So, we can write,

1 liter water = 1 kg water

1.98 liters water = 1.98 kg water.

So, the mass of the water is 1.98 kg.

The weight of a body is given as,

W = Mg

Where,

M is mass of the body and g is the gravitational acceleation,

putting values to find the weight of 1.98 L of water,

W = 1.98 x 10

W = 19.8N.

Converting it into Pounds,

W = 4.45 Pounds force.

Given:

a fair coin is flipped repeatedly until 50 heads are observed

using the central limit theorem, calculate an approximate value for the probability that at least 80 flips are necessary.

P (h>25)=p(h>=26)= 1-p(h<=26)

Assume the situation is approximately normal

u= np =50(1/2)=25 , s=√(npq) = √( 50)(.5)(.5) =√12.5

z=(x-u)/s = ( 26–25)/√12.5 = 0.283

P(z=0.283) =0.1103

A rancher is filling a trough for her horses. The trough already contains 25 gallons of water, and the rancher is adding 11 gallons per minute. How long will it take for the trough to have 80 gallons of water?
Write and solve an equation to find the answer. How many minutes.

Answers

Answer: 5 minutes

Step-by-step explanation: The total change in the amount of water in the trough is the difference between the final amount and the initial amount, which is 80 gallons - 25 gallons = 55 gallons.

Since the rancher is adding 11 gallons of water per minute, the time it will take for the trough to have 80 gallons of water is the total change in the amount of water divided by the rate at which the water is being added, which is 55 gallons / 11 gallons/minute = 5 minutes.

Therefore, it will take the rancher 5 minutes to fill the trough with 80 gallons of water.

The correct option d. 0.109, for the probability of the event: exactly 6 heads out of 8.

Describe the term binomial distribution?The possibility that a value would take one of 2 independent values given a particular combination of factors or assumptions is captured by the statistical distribution known as the binomial distribution.

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

The probability of getting one head = 1/2.

p = 0.5.

Thus, the probability of getting one tail = 1/2

q = 0.5

Thus, for exactly 6 heads

P(X = 6) =  ⁸C₆. (0.5)⁶ (0.5)²

P(X = 6) = 0.109

thus, k=-31/11-22/5

At a 4.5% annual growth rate, it will take 8.4 years to double the population from 15,000 to 20700.

What is percent?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Here,

The initial population=15000

Growth rate=4.5%

Final population=20700

Population growth=15000*4.5%

=675

Let n be the number of years.

Final population=initial population + Population growth*number of years

A rectangle is shown on a coordinate plane with vertices A(Negative 4, 8), B(1, 8), C(1, Negative 1), and D(Negative 4, Negative 1).


On a coordinate plane, a rectangle has 4 points. Point A is (negative 4, 8), point B is (1, 8), point C is (1, negative 1), point D is (negative 4, negative 1).


What are the dimensions of the rectangle?

The base is 4 units and the height is 9 units.

The base is 5 units and the height is 7 units.

The base is 5 units and the height is 9 units.

The base is 9 units and the height is 3 units..

Answers

Answer: The base is 4 units and the height is 9 units.

Step-by-step explanation: To find the dimensions of the rectangle, we can use the coordinates of the points A, B, C, and D. The base of the rectangle is the distance between the points A and B, or the distance between the points C and D. We can find this distance by subtracting the x-coordinates of the points: 1 - (-4) = 5. Therefore, the base of the rectangle is 5 units.

Next, we can find the height of the rectangle by subtracting the y-coordinates of the points A and C, or the points B and D. We can do this by subtracting the y-coordinates of the points: 8 - (-1) = 9. Therefore, the height of the rectangle is 9 units.

Therefore, the dimensions of the rectangle are a base of 5 units and a height of 9 units, so the correct answer is A; The base is 4 units and the height is 9 units.

the number line shows point m at 15,490 rounded to the nearest thousand?

Answers

Answer:

I can't see the number line, but I'll say 15,000

The solution is, 15000 when 15,490 rounded to the nearest thousand.

What is round off?

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

here, we have,

given that, 15,490

now, we have to rounded to the nearest thousand.

we get, 490 < 500

so, it is 15000

Hence, The solution is, 15000 when 15,490 rounded to the nearest thousand.
