The minimum relative frequency of data greater than 80 but less than 140 is 0.9973 or approximately 99.73%.

To find the minimum relative frequency of data greater than 80 but less than 140, we need to use the z-score formula, which measures the number of standard deviations a data point is from the mean.

z = (x - μ) / σ

where x is the data point, μ is the mean, and σ is the standard deviation.

For x = 80:

z = (80 - 110) / 10 = -3

For x = 140;

z = (140 - 110) / 10 = 3

Using a standard normal distribution table or calculator, we can find that the area under the curve between z = -3 and z = 3 is approximately 0.9973.

Therefore, the minimum relative frequency of data greater than 80 but less than 140 is 0.9973 or approximately 99.73%.

The solutions of the equation k² - 3k = 10 are k = 5 and k = -2.

We have,

To solve the equation k² - 3k = 10 using the zero product property, we first rearrange the terms so that one side of the equation is zero:

k² - 3k - 10 = 0

k² - (5 - 2)k - 10 = 0

k² - 5k + 2k - 10 = 0

k(k - 5) + 2(k - 5) = 0

(k - 5)(k + 2) = 0

According to the zero product property,

If the product of two factors is zero, then at least one of the factors must be zero.

So we set each factor equal to zero and solve for k:

k - 5 = 0 or k + 2 = 0

k = 5 or k = -2

Therefore,

The solutions of the equation k² - 3k = 10 are k = 5 and k = -2.

This gives us an estimated probability of approximately 0.00006, or 0.006%.

Without knowing any further information about the distribution or characteristics of the population, it is impossible to provide an accurate estimate of the probability of observing exactly 39 blue eyed blonde haired people in a group of a certain size.

However, if we assume that the two variables (eye color and hair color) are independent and randomly distributed within the population, then we can use the binomial distribution to estimate the probability of observing exactly 39 people with both blue eyes and blonde hair in a group of a certain size.

The formula for the binomial distribution is:

[tex]P(X = k) = (n choose k) \times p^k \times (1-p)^{(n-k)[/tex]

Where:

P(X = k) is the probability of observing exactly k successes (in this case, 39 blue eyed blonde haired people)

n is the total number of trials (the size of the group)

k is the number of successes (39)

p is the probability of success (the probability of observing someone with blue eyes and blonde hair in the population)

Since we don't have any specific information about the population, we can't determine p directly. However, if we assume that the probability of someone having blue eyes is 0.2 and the probability of someone having blonde hair is 0.25 (which are rough estimates based on global averages), then we can estimate the probability of someone having both blue eyes and blonde hair as:

p = 0.2 × 0.25 = 0.05

Assuming a group size of 1000 people, we can use the binomial distribution to estimate the probability of observing exactly 39 blue eyed blonde haired people as:

[tex]P(X = 39) = (1000 choose 39) \times 0.05^{39} \times (1-0.05)^{(1000-39)}[/tex]

This gives us an estimated probability of approximately 0.00006, or 0.006%. However, it's important to note that this is just an estimate based on certain assumptions, and the true probability could be higher or lower depending on the actual characteristics of the population.

The "significance level" of the test is the probability level necessary for statistical significance prior to using inferential statistics.

Inferential statistics is a branch of statistics that involves making inferences about a population based on a sample. One of the key concepts in inferential statistics is the significance level, which is the probability level below which the results of a statistical test are considered statistically significant.

The significance level, also known as alpha (α), is typically set at 0.05 or 0.01, although other values may be used depending on the specific research question and context. The significance level represents the probability of rejecting the null hypothesis when it is true, which is also known as a Type I error. In other words, it represents the likelihood of concluding that there is a significant effect or difference in the population when there really isn't one.

When conducting a statistical test, researchers calculate a p-value, which represents the probability of obtaining the observed results or more extreme results under the null hypothesis. If the p-value is less than or equal to the significance level, then the results are considered statistically significant, and the null hypothesis is rejected in favor of the alternative hypothesis.

A series is said to converge conditionally if it converges, but the associated series formed by taking the absolute values of its terms does not converge. This concept mainly applies to alternating series, which have terms that alternate in sign, i.e., positive and negative terms.

To determine if a series converges conditionally, you can apply the Alternating Series Test and the Comparison Test or the Limit Comparison Test.

1. Alternating Series Test: If a series is alternating and satisfies these two conditions, it converges:
  a) The terms are decreasing in magnitude, i.e., |a_n+1| ≤ |a_n|.
  b) The limit of the terms as n approaches infinity is zero, i.e., lim(n→∞) |a_n| = 0.

2. Comparison Test or Limit Comparison Test: Apply either of these tests to the series formed by taking the absolute values of the terms. If the series diverges, then the original series converges conditionally.

To identify conditional convergence, ensure that the alternating series converges and the series with absolute values diverges.

B) The sequence diverges.

For sequence A, we can simplify the expression by dividing both the numerator and denominator by n^2. This gives us:

a_n = √(1 + 4/n^2)/(1 + 1/n^2)

As n approaches infinity, the terms in the denominator become negligible compared to the terms in the numerator. Therefore, the sequence converges to:

lim a_n = √(1 + 0)/1 = 1

For sequence B, we know that the cosine function oscillates between -1 and 1, so the sequence will oscillate as well.

It is more difficult to establish nonspuriousness in quasi-experiment designs, where do not use randomization to assign subjects to treatment and comparison groups. So, option(c) is right.

The prefix quasi means "resembling". Thus, quasi-experimental research is a type of research which resembles to experimental research but it is not a true experimental research. These designs are similar to true experiments but lack random assignment to experimental and control groups. A true experiment, a quasi-experimental design, aims to establish a cause-and-effect relationship between an independent and a dependent variable. Aim of these experiments is to evaluate interventions but without use of randomization. Subjects are assigned to groups based on non-random criteria.

The angle of depression from plane to the building for the given situation of taking photographs is equal to 30.027°.

Height for the best photograph = 403ft

Distance from the top of the building = 810 ft

As the given figure represents it is right angled triangle.

Horizontal vision from top of the building to the base are parallel.

Angle of depression and angle of elevation represents alternate angles

This implies,

Measure of angle of depression = Measure of angle of elevation

Let us consider angle of elevation be α .

In right angled triangle,

sin α = ( height of the building ) / (distance from the building)

Substitute the values we have,

Thus, the probability of getting at least 5 questions correct by guessing randomly on a 20-question multiple-choice test with 4 possible answers for each question is approximately 0.074 or 7.4%.

To calculate the probability of getting at least 5 questions correct, we need to use the binomial distribution formula. This formula calculates the probability of getting a specific number of successes in a fixed number of trials, given a specific probability of success.

The formula for the probability of getting at least 5 successes in 20 trials with a probability of success of 1/4 is:

P(X ≥ 5) = 1 - P(X < 5)

where X is the number of correct answers.

Using the binomial distribution formula, we can calculate the probability of getting less than 5 correct answers as:

P(X < 5) = ΣP(X = k) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

= (0.75)^20 + 20(0.25)(0.75)^19 + (20*19/2)(0.25)^2(0.75)^18 + (20*19*18/6)(0.25)^3(0.75)^17 + (20*19*18*17/24)(0.25)^4(0.75)^16

= 0.926

Therefore, the probability of getting at least 5 questions correct is:

P(X ≥ 5) = 1 - P(X < 5)

= 1 - 0.926

= 0.074

The war was launched in response to the belief that Iraq possessed weapons of mass destruction and that the country was a threat to international security. However, no such weapons were found, and the justifications for the war were widely debated and criticized.

The conflict resulted in the overthrow of Saddam Hussein's regime, and the subsequent establishment of a new government in Iraq. However, the war also led to a large number of casualties on both sides, with estimates of civilian deaths ranging from 100,000 to over 1 million.

The expected number of empty bins when tossing n balls into n bins, with each toss being independent and equally likely, can be determined using the concept of probability.

Let's define the probability that a specific bin remains empty after n tosses as P(empty). Since each ball has n choices, there are n^n possible ways to distribute the balls. To find the probability that a specific bin is empty, we can consider the situation where balls can be tossed into the remaining n-1 bins, resulting in (n-1)^n possible distributions. Therefore, P(empty) = ((n-1)^n) / (n^n).

Now, to calculate the expected number of empty bins, we can use the concept of linearity of expectation. The expected value of the sum of random variables is equal to the sum of the expected values of the individual random variables. In this case, the random variables represent the empty status of each bin (1 if empty, 0 if not).

The expected number of empty bins is the sum of the probabilities of each bin being empty, which is n * P(empty). So, the expected number of empty bins = n * (((n-1)^n) / (n^n)).

Using this formula, you can determine the expected number of empty bins when n balls are tossed into n bins independently and with equal likelihood.

If the chance of failure is independent of another's failure, it means that the probability of each individual failing is the same, and we can assume that the failures follow a binomial distribution.

Let p be the probability of an individual failing, and n be the number of trials (in this case, the number of users, n = 20).

The probability of exactly k failures out of n trials is given by the binomial probability formula:

[tex]P(k) = (n choose k) \times p^k \times (1-p)^{(n-k)[/tex]

where (n choose k) is the binomial coefficient, equal to n! / (k! × (n-k)!).

To find the individual failure rate needed for 20% of 20 users to fail, we need to solve for p such that P(4) = 0.2, where k = 4 is the number of failures we want to allow.

The train will arrive at its final destination at 2:57 P.M. in the afternoon.

The total distance of the trip is 221 miles and the train travels at an average speed of 34 miles per hour. Using the formula:

time = distance / speed

We can calculate the total time it will take for the train to complete the journey without stopping at stations:

time = 221 / 34 = 6.5 hours

However, the train stops at each of ten stations for four minutes each, so the total time spent stopping is 10 x 4 = 40 minutes, or 0.67 hours. Therefore, the total time the journey will take, including the stops, is:

total time = 6.5 + 0.67 = 7.17 hours

The train departs at 7:30 A.M., so we can add 7.17 hours to this time to find the arrival time:

7:30 A.M. + 7.17 hours = 2:57 P.M.
