The color of the origin (0, 0, 0) is green.

To determine the color of the origin (0, 0, 0) using the k-nearest neighbors algorithm with k equals 3 and the distance function d((z1, z2, z3), (w1, w2, w3)) = Σ|i=1 to 3| |zi - wi|.

we need to find the three nearest neighbors to the origin based on the given training data set.

Calculating the distances between the origin and each observation:

The three nearest neighbors to the origin are observations 2, 5, and 6, with distances of 2, 2, and 3, respectively.

Among these neighbors, two are green and one is red. Since green has a higher count, the color of the origin (0, 0, 0) would be **green**.

It could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.

The most accurate interpretation of the given confidence interval is as follows:

We are 95% confident that the true difference in mean wait time between Facility A and Facility B falls within the range of 0.32 minutes to 1.47 minutes.

This means that if we were to repeat the study multiple times and calculate a new confidence interval each time, we would expect that approximately 95% of those intervals would contain the true difference in mean wait time between the two facilities.

Furthermore, based on the observed data and the calculated confidence interval, we can conclude that the difference in mean wait time between Facility A and Facility B is likely to be positive, with Facility B having a higher mean wait time than Facility A. However, we cannot say with certainty that the true difference is exactly within this specific range; it could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.

While a common rule of thumb is to have a minimum sample size of 100 for continuous data to be statistically significant, the actual appropriate sample size may vary depending on the specific study design and research question. Option(D)

In statistics, the term "statistical significance" refers to whether an observed effect or relationship in the data is likely to be real and not just due to random chance. To determine statistical significance, we often perform hypothesis testing.

The sample size is a crucial factor in hypothesis testing. A larger sample size generally provides more reliable and precise estimates of population parameters and increases the statistical power of the test. With a larger sample size, even smaller effects or differences between groups can become statistically significant.

While there is no hard and fast rule for the minimum sample size to achieve statistical significance, a common guideline is to aim for at least 30 samples. This guideline is often used in the context of the Central Limit Theorem, which states that the sampling distribution of the sample mean becomes approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In practice, the appropriate sample size depends on various factors, including the nature of the data, the effect size being studied, the desired level of confidence, and the statistical test used. Researchers often conduct sample size calculations based on these factors before conducting their studies to ensure they have an adequate sample size to achieve meaningful results and detect significant effects if they exist.

The average velocity from t = 2s to t = 4s would be - 48 ft/s.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.

Average rate of change of velocity with time is called average velocity. Mathematically -

v{avg.} = Δx/Δt                                                         .... Eq { 1 }

Δx = x(4) - x(2)

Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}

Δx = - 96

Δt = 4 - 2 = 2

So -

v{avg.} = Δx/Δt = -96/2 = - 48 ft/s

Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

Answer:

15 is the correct answer

There are 1820 different groups of applicants for 4 management trainee positions, 126 different groups of trainees consisting entirely of women, and a 0.0692 probability that the trainee class will consist entirely of women.

The number of different groups of applicants that can be selected for the four management trainee positions can be calculated using the combination formula:

nCr = n! / (r! * (n-r)!)

where n is the total number of applicants (16 in this case) and r is the number of positions to be filled (4 in this case).

So the number of different groups of applicants that can be selected is:

16C4 = 1820

Therefore, there are 1820 different groups of applicants that can be selected for the four management trainee positions.

The number of different groups of trainees that would consist entirely of women can be calculated using the combination formula again, but this time we are selecting all 4 positions from the 9 female applicants:

9C4 = 126

Therefore, there are 126 different groups of trainees that would consist entirely of women.

Assuming that all groups of four are equally likely to be selected, the probability that the trainee class will consist entirely of women can be calculated by dividing the number of different groups of trainees that consist entirely of women (126) by the total number of different groups of applicants (1820):

Probability = 126 / 1820 = 0.0692

So the probability that the trainee class will consist entirely of women is 0.0692 (rounded to four decimal places).

Answer:

the sum of interior angles of a pentagon is 540°

Step-by-step explanation:

To find the probability that more than 5 people enter the store in a given 3 minute period, we need to calculate the Poisson probability distribution. The Poisson distribution models the number of events occurring in a fixed interval of time or space.

First, we need to calculate the average number of people that enter the store in a 3-minute period. Since, on average, 100 people visit the store per hour, we divide this by 60 to get the average number of people per minute:

\(100/60 = 5/3\)
Now, we can use the Poisson distribution formula to calculate the probability. The formula is:

\(P(x > k) = 1 - P(x \leq  k),\)

where k is the number of events (in this case, 5).

Using the Poisson distribution formula, we can calculate:

\(P(x > 5) = 1 - P(x \leq  5)\)

\(= 1 - [e^{-\lambda} * (\lambda^0 / 0!) + e^{-\lambda} * (\lambda^1 / 1!) + e^{-\lambda} * (\lambda^2 / 2!) + e^{-\lambda} * (\lambda^3 / 3!) + e^{-\lambda} * (\lambda^4 / 4!) + e^{-\lambda} * (\lambda^5 / 5!)],\)

where λ is the average number of events (5/3).

Calculating this, we find the probability that more than 5 people enter the store in a given 3-minute period. However, the specific value cannot be determined without knowing the value of λ.

To find the probability that more than 5 people enter the store in a given 3-minute period, we can use the concept of a Poisson distribution. The Poisson distribution is used to model the number of events that occur within a fixed interval of time or space, given the average rate at which these events occur. After calculating the values, we can sum them up to find \(P(x \leq 5)\), and then subtract this from 1 to find \(P(x > 5)\).

In this case, we are given that the average rate at which people stop by the store is 100 per hour. To find the rate per minute, we can divide this average by 60 (since there are 60 minutes in an hour):

Rate per minute = \(\frac{100}{60}\) = 1.67 people per minute.

Now, we can use this rate to calculate the probability that more than 5 people enter the store in a 3-minute period. The formula for the Poisson distribution is:

\(P(x; \lambda) = \frac{e^{-\lambda} * \lambda^x}{x!}\)

Where:

- \(P(x; \lambda)\) is the probability of x events occurring,

- \(\lambda\) is the average rate at which events occur (in this case, the rate per minute),

- \(e\) is the mathematical constant approximately equal to 2.71828, and

- \(x!\) is the factorial of x.

Let's calculate the probability:

\(P(x > 5) = 1 - P(x \leq 5)\)

To calculate \(P(x \leq 5)\), we can sum up the probabilities of having 0, 1, 2, 3, 4, or 5 people entering the store in a 3-minute period. Using the Poisson distribution formula for each value of x, we get:

\(P(x \leq 5) = P(0) + P(1) + P(2) + P(3) + P(4) + P(5)\)

We can calculate each term using the formula:

\(P(x) = \frac{e^{-\lambda} * \lambda^x}{x!}\)

Substituting \(\lambda = 1.67\) and \(x = 0, 1, 2, 3, 4, 5\), respectively, we get:

\(P(0) = \frac{e^{-1.67} * 1.67^0}{0!}\) = 0.188

\(P(1) = \frac{e^{-1.67} * 1.67^1}{1!}\) = 0.313

\(P(2) = \frac{e^{-1.67} * 1.67^2}{2!}\) = 0.261

\(P(3) = \frac{e^{-1.67} * 1.67^3}{3!}\) = 0.146

\(P(4) = \frac{e^{-1.67} * 1.67^4}{4!}\) = 0.061

\(P(5) = \frac{e^{-1.67} * 1.67^5}{5!}\) = 0.020

After calculating these values, we can sum them up to find \(P(x \leq 5)\), and then subtract this from 1 to find \(P(x > 5)\).
