The normal approximation to the binomial distribution also implies that the sampling distribution of p is roughly bell-shaped, as the normal distribution is. Therefore, the answer is A) The shape.

The sampling distribution of the proportion is the distribution of all possible values of the sample proportion that can be calculated from all possible samples of a certain size taken from a particular population in statistical theory. The state of the examining dispersion of p is generally chime molded, as it is an illustration of a binomial conveyance with enormous n and moderate p.

The example size (n=900) is sufficiently enormous to legitimize utilizing an ordinary guess to the binomial dissemination, as indicated by as far as possible hypothesis. In order for the binomial distribution to be roughly normal, a sample size of at least 30 must be present, which is achieved.

Subsequently, the examining dispersion of p can be thought to be around ordinary with a mean of 0.532 and a standard deviation of roughly 0.0185 (involving the equation for the standard deviation of a binomial distribution).The typical estimate to the binomial dissemination likewise infers that the inspecting conveyance of p is generally chime molded, as the ordinary circulation is. As a result, A) The shape is the response.

By mathematical induction, the formula holds for all positive integers n, and the Tower of Hanoi game with n discs can be solved with a minimum of 2n - 1 steps.

Explain:

I will use mathematical induction to show that the equation I derived in answer 1 holds for the bare minimum of movements needed to solve the Tower of Hanoi game for any specific number of discs.

Let's first review the formula:

Code's minimal motion count is 2n - 1, where n is the total number of discs.

Base case: The least number of moves needed is 21 - 1 = 1, which corresponds with the formula when there is only one disc and we can move it from the beginning peg to the ending peg with just one move.

Step one of induction: Assume that the formula is valid for n=k, where k is a positive integer. If so, then 2k - 1 moves are the absolute least needed to solve the Tower of Hanoi game using k discs. We must demonstrate that the formula also applies to n=k+1, i.e., that 2(k+1) - 1 movements are all that are needed to solve the Tower of Hanoi game with k+1 discs.

We can divide the issue into three steps to move k+1 discs from the starting peg to the ending peg:

Step 1: Using the ending peg as a spare, move k discs from the beginning peg to the spare peg.

Step 2: Transfer the final disc from the beginning to the finish peg.

Step 3: Using the beginning peg as a spare, move the k discs from the spare peg to the ending peg.

According to the inductive hypothesis, Step 1 and Step 3 both necessitate a minimum of 2k - 1 moves. The least amount of moves necessary to complete the procedure is one for Step 2, making a total of:

scss

Duplicate the formula-conforming code 2k - 1 + 1 + 2k - 1 = 2(k+1) - 1.

As a result, by mathematical induction, the formula is true for all positive integers n, and 2n - 1 movements are all that are needed to solve the Tower of Hanoi game with n discs.

The probability of a home for sale having a garage but no pool is 0.42.

To do this, we need to use some probability rules. One useful rule is the formula for calculating the probability of an event not occurring. This is given by:

P(not A) = 1 - P(A)

where A is the event we are interested in, and not A is the event of A not occurring.

In this case, we are interested in the probability of a home having a garage but no pool. Let's call this event GNP (short for garage no pool). Using the information given, we know that 60% of homes have garages and 18% have both garages and pools. We can use this information to calculate the probability of a home having a garage but no pool as follows:

P(GNP) = P(G) - P(G and P)

where G is the event of a home having a garage and P is the event of a home having a pool.

Substituting the values we have:

P(GNP) = 0.6 - 0.18

The trip to the seashore takes about 2.1 hours (rounded to the nearest hundredth).Thus, the correct option is 2.1 hours.

In this question, Patch traveled from his office to the seashore at a speed of 62 mph. He traveled the same route back to his office but on the return trip his speed was 66 mph.

If altogether, Patch spent a total of 4 hours on the road, we have to calculate how many hours did the trip to the seashore take.To solve this problem,

we will use the formula of speed, distance and time:Speed = Distance / Timeor Distance = Speed x TimeWe have given that the distance between Patch’s office and seashore is the same for both the trip to and from the seashore.

Let's suppose that the distance between the Patch’s office and seashore is “d”.Given speed when he travels from office to seashore = 62 mph

Time taken to travel from office to seashore = Distance / Speed= d / 62Given speed when he travels from seashore to office = 66 mph

Time taken to travel from seashore to office = Distance / Speed= d / 66Total time taken = Time taken from office to seashore + Time taken from seashore to office= d / 62 + d / 66= (33d + 31d) / (62 x 66) = 64d / 2046= 32d / 1023We have given that Total time taken by Patch is 4 hours.

Therefore,32d / 1023 = 4d = 1023/8 ≈ 127.88 milesNow, we know the distance is 127.88 miles and speed is 62 mph. Therefore,Time taken to travel from office to seashore = Distance / Speed= 127.88 / 62= 2.06 ≈ 2.1 hours

Using synthetic division, we can divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1. Performing the synthetic division, we obtain a quotient of x² + 6x - 6 and a remainder of 8.

To divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1 using synthetic division, we set up the synthetic division table as follows:

1  |   1   7  -12   14

We begin by bringing down the coefficient of the first term, which is 1, and place it on the line below the division bar. Then we multiply the divisor, 1, by the value we brought down and write the result under the next coefficient. Adding the values in the second row, we obtain the new value. We continue this process for each term until we reach the last term.

1  |   1   7  -12   14

 1   8  -4     10

The values in the last row represent the coefficients of the quotient polynomial. Therefore, the quotient is x² + 6x - 6. The remainder, which is the last value in the last row, is 10. Since the divisor is 1, the remainder does not affect the quotient. Hence, the result of the division is x² + 6x - 6 with a remainder of 10.

For the first sample {2.038 2.054 2.053 2.055 2.059 2.059 2.009 2.042 2.053 2.047}, the process is still "in order," while for the second sample {2.022 1.997 2.044 2.044 2.032 2.045 2.045 2.047 2.030 2.044}, the process might be "out of order."

To determine whether the process is still "in order" or "out of order," we can compare the current sample of output to the known mean and standard deviation of the process.

For the first sample {2.038 2.054 2.053 2.055 2.059 2.059 2.009 2.042 2.053 2.047}:

Calculate the sample mean by summing up all the values in the sample and dividing by the number of values (n = 10):

Sample mean = (2.038 + 2.054 + 2.053 + 2.055 + 2.059 + 2.059 + 2.009 + 2.042 + 2.053 + 2.047) / 10 = 2.048.

Compare the sample mean to the known process mean (2.050):

The sample mean (2.048) is very close to the process mean (2.050), indicating that the process is still "in order."

Calculate the sample standard deviation using the formula:

Sample standard deviation = sqrt(sum((x - mean)^2) / (n - 1))

Using the formula with the sample values, we find the sample standard deviation to be approximately 0.019 liters.

Compare the sample standard deviation to the known process standard deviation (0.020):

The sample standard deviation (0.019) is very close to the process standard deviation (0.020), further supporting that the process is still "in order."

For the second sample {2.022 1.997 2.044 2.044 2.032 2.045 2.045 2.047 2.030 2.044}:

Calculate the sample mean:

Sample mean = (2.022 + 1.997 + 2.044 + 2.044 + 2.032 + 2.045 + 2.045 + 2.047 + 2.030 + 2.044) / 10 ≈ 2.034

Compare the sample mean to the process mean (2.050):

The sample mean (2.034) is noticeably different from the process mean (2.050), indicating that the process might be "out of order."

Calculate the sample standard deviation:

The sample standard deviation is approximately 0.019 liters.

Compare the sample standard deviation to the process standard deviation (0.020):

The sample standard deviation (0.019) is similar to the process standard deviation (0.020), suggesting that the process is still "in order" in terms of variation.

In summary, for the first sample, the process is still "in order" as both the sample mean and sample standard deviation are close to the known process values.

However, for the second sample, the difference in the sample mean suggests that the process might be "out of order," even though the sample standard deviation remains within an acceptable range.
