e) The test statistic and P-value for the chi-square test of homogeneity would be -1.75 and 0.004, respectively.

A chi-square test of homogeneity is a useful tool for comparing two or more categorical variables. In this case, the two variables are smoking (smokers and non-smokers) and alcohol consumption (those who had consumed alcohol in the past week and those who hadn't).

The chi-square statistic is calculated by finding the difference between the observed and expected frequencies of the two groups and squaring it. The expected frequencies are found by multiplying the sample size by the overall probability of success (in this case, drinking alcohol).

The P-value is then calculated based on the chi-square statistic and the degrees of freedom (in this case, one). In this case, the chi-square statistic is -1.75 and the P-value is 0.004.

To find the vertical asymptotes of a rational function, we need to set the denominator equal to zero and solve for x.

To find the vertical asymptotes of a rational function, you need to determine the values of x that make the denominator of the function equal to zero.

Let's check the limit of our example function as x approaches each of the vertical asymptotes:

As x approaches 1 from the left side: f(x) approaches negative infinity

As x approaches 1 from the right side: f(x) approaches positive infinity

Therefore, x = 1 is a valid vertical asymptote.

As x approaches 3 from the left side: f(x) approaches positive infinity

As x approaches 3 from the right side: f(x) approaches negative infinity

Therefore, x = 3 is also a valid vertical asymptote.

The values of x that make the denominator zero are the vertical asymptotes of the function.

We were given that:

At equilibrium, we have:

The given series, 2, 1, 3, 2, 4, is not alternating series with given partial sum.

A series in which the terms' signs alternate between positive and negative is known as an alternating series. The signs of the words in the given series—2, 1, 3, 2, 4—do not rotate regularly. The signs change between the first two phrases (2 and 1), but they do not change between the following terms. The alternating pattern is broken by the third term, 3, which is positive. As a result, the described series does not satisfy the requirements of an alternating series with given partial sum.

Let's examine the signs of the terms in the series to further demonstrate this. The initial term, 2, is favourable. The next term, 1, is unfavourable. Until now, the indicators have changed. The third term, 3, on the other hand, is positive, breaking the alternating pattern. The third term does not alternate with the fourth term, 2, which is positive once more. In line with the fourth term, the fifth term, 4, is also good. Because the series' sign alternation is inconsistent, it cannot be considered an alternating series.

Step-by-step explanation:

Multiply the number by two and then add the number right before it.

46*2+19=111

f(n) = ϴ(g(n)) is not true in cases B(sqrt(n)log(n), C(\(3^n 5^n\)), and D(sin(n)+3 cos(n)+1).

A) \(log(n^200) log(n^2)\)

Here, f(n) = \(log(n^200)\) and g(n) = \(log(n^2)\). Now, if we take the limit of f(n) / g(n) as n approaches infinity, then:

f(n) / g(n) = \([log(n^200) / log(n^2)]\) = 100

This means that as n approaches infinity, the ratio f(n) / g(n) is constant, and so we can say that f(n) = ϴ(g(n)). Therefore, f(n) = ϴ(g(n)) is true in this case.

B) sqrt(n) log(n) Here, f(n) = sqrt(n) and g(n) = log(n). Now, if we take the limit of f(n) / g(n) as n approaches infinity, then:

f(n) / g(n) = [sqrt(n) / log(n)]

As log(n) grows much slower than sqrt(n) as n approaches infinity, this limit approaches infinity. Therefore, we cannot say that f(n) = ϴ(g(n)) is true in this case.

C) 3^n 5^n

Here, f(n) = \(3^n\) and g(n) = \(5^n\) . Now, if we take the limit of f(n) / g(n) as n approaches infinity, then:

f(n) / g(n) = \([3^n / 5^n]\)

As \(3^n\) grows much slower than \(5^n\) as n approaches infinity, this limit approaches zero. Therefore, we cannot say that f(n) = ϴ(g(n)) is true in this case.

D) sin(n) + 3 cos(n) + 1

Here, f(n) = sin(n) + 3 and g(n) = cos(n) + 1. Now, if we take the limit of f(n) / g(n) as n approaches infinity, then:

f(n) / g(n) = [sin(n) + 3] / [cos(n) + 1]

As this limit oscillates between positive and negative infinity as n approaches infinity, we cannot say that f(n) = ϴ(g(n)) is true in this case.

Therefore, f(n) = ϴ(g(n)) is not true in cases B, C, and D.

Answer:

c = 4

Step-by-step explanation:

\(2(c+1) = 10\)

Lets divide both the sides by 2.

\(=> \frac{2 (c+1)}{2} = \frac{10}{2}\)

\(=> c + 1 = 5\)

Now , lets substract 1 on both the sides.

\(=> c + 1 - 1 = 5 - 1\)

\(=> c = 4\)

The solution to the equation 2(c + 1) = 10 is c = 4.

We have,

To solve for c in equation 2(c + 1) = 10, we will apply the distributive property and simplify the equation step by step.

Let's solve it:

Distribute the 2 to the terms inside the parentheses:

2c + 2 = 10

Move the constant term (2) to the right side by subtracting 2 from both sides of the equation:

2c + 2 - 2 = 10 - 2

Simplifying further:

2c = 8

Divide both sides of the equation by 2 to solve for c:

(2c) / 2 = 8 / 2

Simplifying further:

c = 4

Therefore,

The solution to the equation 2(c + 1) = 10 is c = 4.

The graphic device that is best suited for comparing how an interval-ratio variable is distributed across two or more groups or time periods is the boxplot.

It is also called a box-and-whisker plot, this plot displays the distribution of a quantitative variable within one or multiple groups through their quartiles, outliers, and median. A boxplot portrays the variability of the dataset with the help of five important summary statistics: minimum, maximum, median, first quartile, and third quartile. The interquartile range is the distance between the first and third quartiles. The box represents the interquartile range, while the whiskers extend from the edges of the box to the maximum and minimum values that are not outliers.

The outliers are plotted separately from the box, a boxplot is best suited for identifying the median, variability, skewness, and the presence of outliers. It is an effective way to compare the distribution of one or multiple variables across different groups or time periods. In conclusion, boxplots are an ideal graphic device for representing the distribution of interval-ratio variables across multiple groups or time periods, making it easier to analyze the data and gain valuable insights.

Donald paid the wager to Bill after losing the bet, he may not be able to recover the funds from Bill.

Given that Donald had willingly fulfilled his part of the bet by paying the wager to Bill, it would be difficult for him to recover the funds. Generally, once a payment is made and received, it is considered a final transaction, and the payer loses any legal entitlement to demand a refund. This principle is known as the "doctrine of consideration" or "consideration of contract."

In this case, Donald voluntarily transferred the funds to Bill, acknowledging his loss and fulfilling his obligation under the bet. Consequently, Donald may not have a legal basis to recover the funds from Bill, as he has already relinquished his claim to them.
