The probability of rolling a sum of 12 with these dice is  1/36.

The likelihood of rolling an entirety of 12 with two standard dice can be found utilizing the equation:

P(D1 + D2 = 12) = number of ways to induce an entirety of 12 / total possible results

There's as it were one way to roll a whole of 12: rolling a 6 on both dice.

The whole conceivable results can be found by noticing that there are 6 conceivable results for each dice roll, since each kick the bucket has 6 sides. In this manner, the whole number of conceivable results is:

6 x 6 = 36

So the likelihood of rolling a whole of 12 with two standard dice is:

P(D1 + D2 = 12) = 1/6 * 1/6 = 1/36

It is proved that if g is not cyclic, all elements of g have order 1, 2, or 3, and there must be an element of order 3.

To prove that if g is not cyclic, all elements of g have order 1, 2, or 3, and show that there must be an element of order 3, follow these steps,

1. Assume that g is a finite group and is not cyclic.
2. Recall that the order of an element a in group g is the smallest positive integer n such that a^n = e, where e is the identity element in g.
3. If g were cyclic, it would have an element a with order equal to the order of the group itself (|g|). However, we are given that g is not cyclic, so the order of any element in g must be less than |g|.
4. We now consider the possibilities for the order of elements in g. If all elements of g have order 1, then g is the trivial group, which is cyclic, contradicting our assumption.
5. If there is an element of order 2, there must be an element of order 3 as well. This is because, according to Cauchy's theorem, if a prime number p divides the order of a finite group g, then g has an element of order p. Since we have assumed that g is not cyclic, |g| must be divisible by at least two prime numbers. The smallest possible case is when |g| is divisible by the primes 2 and 3.
6. By Cauchy's theorem, since 2 and 3 both divide |g|, there must be elements in g of order 2 and order 3.
7. Therefore, if g is not cyclic, all elements of g have order 1, 2, or 3, and there must be an element of order 3.

We first calculate the z-score:

z = (0.517 - 0.61) / sqrt((0.61 * (1 - 0

To solve these probability questions, we need to use the central limit theorem, which states that if we have a large enough sample size, the sampling distribution of the sample proportion will be approximately normal, regardless of the population distribution.

For a sample of size n, the mean of the sample proportion (p) is equal to the population proportion (p), and the standard deviation of the sample proportion (σp) is equal to:

σp = sqrt((p(1-p))/n)

Using this information, we can standardize the sample proportion using z-score:

z = (p - p) / σp

Then, we can use the standard normal distribution table (such as Appendix A Statistical Tables) to find the probabilities.

a) What is the probability that the sample proportion is greater than 0.643?

We first calculate the z-score:

z = (0.643 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = 3.17

Using the standard normal distribution table, the probability of getting a z-score greater than 3.17 is approximately 0.0008.

Therefore, the probability that the sample proportion is greater than 0.643 is 0.0008.

b) What is the probability that the sample proportion is between 0.60 and 0.647?

We need to calculate the z-scores for both values:

z1 = (0.60 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -1.23

z2 = (0.647 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = 1.79

Using the standard normal distribution table, the probability of getting a z-score between -1.23 and 1.79 is approximately 0.8438.

Therefore, the probability that the sample proportion is between 0.60 and 0.647 is 0.8438.

c) What is the probability that the sample proportion is greater than 0.607?

We first calculate the z-score:

z = (0.607 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -0.73

Using the standard normal distribution table, the probability of getting a z-score greater than -0.73 is approximately 0.7665.

Therefore, the probability that the sample proportion is greater than 0.607 is 0.7665.

d) What is the probability that the sample proportion is between 0.57 and 0.597?

We need to calculate the z-scores for both values:

z1 = (0.57 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -4.13

z2 = (0.597 - 0.61) / sqrt((0.61 * (1 - 0.61)) / 656) = -1.08

Using the standard normal distribution table, the probability of getting a z-score between -4.13 and -1.08 is approximately 0.0361.

Therefore, the probability that the sample proportion is between 0.57 and 0.597 is 0.0361.

Answer:

3 groups of 4 each

Step-by-step explanation:

To determine whether there are more ways to split 12 people up into 4 groups of 3 each or into 3 groups of 4 each, we'll use the combinations formula:

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

First, let's calculate the combinations for 4 groups of 3 people each:
C(12, 3) = 12! / (3!(12-3)!) = 12! / (3!9!) = 220

Now, we need to divide these 12 people into 4 groups, so we'll use the multinomial coefficient formula:

(12!)/(3!3!3!3!) = 34,650

Next, let's calculate the combinations for 3 groups of 4 people each:
C(12, 4) = 12! / (4!(12-4)!) = 12! / (4!8!) = 495

Now, we need to divide these 12 people into 3 groups, so we'll use the multinomial coefficient formula again:

(12!)/(4!4!4!) = 34,650

Comparing the results, we can see that there are equal ways (34,650 ways) to split 12 people up into 4 groups of 3 each or into 3 groups of 4 each.

A recursive formula is one that defines each term in a series by reference to the phrase(s) that came before it. The first term, or firsts, in the series must always be stated in recursive formulae. A recursive algorithm is one that uses "smaller (or simpler)" input values to call itself and gets the result for the current input by performing straightforward operations on the value that was returned for the smaller (or simpler) input.  

And the Fibonacci sequence is the most well-known recursive formula. The following is the Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21,… Keep in mind that each number in the series is the product of the two numbers before it. For instance, the total of the two terms before it, 5 and 8, is 13.

Recursive formula for H(n), we need to find the first term and the common difference.

H(1) = -10 + 12(1) = 2

The required monthly payment for this compound-interest loan is approximately $1,199.10.

Calculating the monthly payment for a compound-interest loan, you will need to use the following formula:

Monthly Payment = [tex]P (r  (1 + r)^n) / ((1 + r)^n - 1)[/tex]

Where:
P, principal amount = $200,000
r, monthly interest rate = annual rate / 12
n, total number of payments = 30 years × 12 payments per year

For this loan:
P = $200,000
Annual Rate = 6% = 0.06
Monthly Rate (r) = 0.06 / 12 = 0.005
Number of Payments (n) = 30 * 12 = 360

Now, putting in the values into the formula:

Monthly Payment = 200,000 × (0.005 × [tex](1 + 0.005)^{360}) / ((1 + 0.005)^{360} - 1)[/tex]

Let A be a square matrix such that some row of A^2 is a linear combination of the other rows of A^2. We need to show that some column of A^3 is a linear combination of the other columns of A^3.

Let’s assume that the ith row of A^2 is a linear combination of the other rows of A^2. Then there exist scalars c1, c2, …, cn such that:

(ai1)^2 + (ai2)^2 + … + (ain)^2 = c1(a11)^2 + c2(a12)^2 + … + cn(a1n)^2 (ai1)^2 + (ai2)^2 + … + (ain)^2 = c1(a21)^2 + c2(a22)^2 + … + cn(a2n)^2 … (ai1)^2 + (ai2)^2 + … + (ain)^2 = c1(an1)^2 + c2(an2)^2 + … + cn(ann)^2

Multiplying each equation by ai1, ai2, …, ain respectively and adding them up gives:

(ai1)(ai1)^2 + (ai2)(ai2)^2 + … + (ain)(ain)^2 = c1(ai1)(a11)^2 + c2(ai2)(a12)^2 + … + cn(ain)(a1n)^2 (ai1)(ai1)^2 + (ai2)(ai2)^2 + … + (ain)(ain)^2 = c1(ai1)(a21)^2 + c2(ai2)(a22)^2 + … + cn(ain)(a2n)^2 … (ai1)(ai1)^2 + (ai2)(ai2)^2 + … + (ain)(ain)^2 = c1(ai1)(an1)^2 + c2(ai22)(an22) ^ 22+ …+cn(ain)(ann) ^ 22

This can be written as:

A^3 * X = B * A^3

where X is the column vector [a11^3, a12^3, …, ann3]T and B is the matrix with entries bi,j = ci * aj^3.

Since the ith row of A^3 is just the transpose of the ith column of A^3, we have shown that some column of A^3 is a linear combination of the other columns of A^3 if some row of A^3 is a linear combination of the other rows of A^3.

If we assume that the probability of each light failing is the same, let's call this probability "p".

To find the maximum allowable probability of failure for each individual light, we can use the binomial distribution.

The probability that the entire strand of lights works is given by the probability that all 10 lights work, which is (1-p)^10.

We want to find the value of p such that this probability is at least 0.9:

(1-p)^10 ≥ 0.9

Taking the logarithm of both sides:

10 log(1-p) ≥ log(0.9)

log(1-p) ≥ log(0.9)/10

1-p ≤ 10^(-log(0.9)/10)

p ≥ 1 - 10^(-log(0.9)/10)

An equation for a line parallel to f(x) = -3x - 5 and passing through the point (2, -6). Here are the steps:

Step 1: Identify the slope of the given line, f(x) = -3x - 5. Since it's in the form y = mx + b, where m is the slope, we see that the slope of the given line is -3.

Step 2: Since we want a line parallel to the given line, the slope of our new line will be the same, which is -3.

Step 3: Use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through. In this case, m = -3 and the point is (2, -6), so x1 = 2 and y1 = -6.

Step 4: Plug the values into the point-slope form equation: y - (-6) = -3(x - 2)

Step 5: Simplify the equation. First, change y - (-6) to y + 6, then distribute -3: y + 6 = -3x + 6

Step 6: Write the equation in slope-intercept form (y = mx + b) by subtracting 6 from both sides: y = -3x

The value of house will be worth $119,600 in four years.

To calculate the value of the house in four years, we need to first determine the total increase in value over that period. Since the value is increasing by $2400 per year, the total increase over four years will be 4 times $2400, or $9600.

Next, we can add the total increase to the current value of the house to find the future value. The current value is given as $110,000, so adding the $9600 increase gives us a future value of $119,600.

Therefore, we can conclude that the value of house will be worth $119,600 in four years, assuming that the annual increase in value remains constant at $2400.
