Step-by-step explanation:

The series [infinity] \((-1)^n\) arctan(n) \(n^7\) n = 1 is convergent and absolutely convergent.

To determine whether the series [infinity] \((-1)^n\) arctan(n) \(n^7\) n = 1 is absolutely convergent, conditionally convergent, or divergent, we can use the alternating series test.

The alternating series test states that if a series is of the form [infinity] Σ \((-1)^n\) u_n, where u_n is a positive decreasing sequence, then the series is convergent.

In this case, we have u_n = arctan(n) \(n^7\), which is a positive decreasing sequence. Therefore, by the alternating series test, the series is convergent.

To determine whether the series is absolutely convergent or conditionally convergent, we can use the comparison test. We can compare the absolute value of the series to a known convergent or divergent series.

Since |arctan(n) \(n^7\)| ≤ \(n^{(-6)\) for all n ≥ 1, we can compare our series to the p-series [infinity] Σ \(n^{-6\), which is known to be convergent. Therefore, the series [infinity] \((-1)^n\) arctan(n) \(n^7\) n = 1 is absolutely convergent.

To calculate the derivative of the given expression, we can apply the Fundamental Theorem of Calculus.

Let's denote the variable of integration as u and differentiate with respect to θ: d/dθ [1∫θ (2cot(u)) du].By the Fundamental Theorem of Calculus, we can differentiate under the integral sign, so we have: = 2cot(θ). Therefore, the derivative of the given expression is 2cot(θ). This means that the rate of change of the integral with respect to θ is given by 2cot(θ).

The cotangent function represents the ratio of the adjacent side to the opposite side in a right triangle, so the derivative tells us how the integral changes as θ varies.

Step-by-step explanation:

You want the round trip distance Hassan walked, if he walked 4.5 miles east to Ben's house, he and Ben walked directly to Jake's house 1.8 miles north of Hassan's, then Hassan walked home from Jake's house.

The distance Hassan walked is the perimeter of the right triangle with legs 4.5 miles and 1.8 miles. The length of the hypotenuse is given by the Pythagorean theorem as ...

  hypotenuse = √(4.5² +1.8²) = √23.49 ≈ 4.8 . . . miles

Step-by-step explanation:

The amount you would pay altogether if you borrow $500 for  5 years at

an annual interest rate of 7% is $945.

The amount you would pay altogether is the sum of the amount borrowed and the interest.

Total value of the debt = interest + amount borrowed

Interest = $700 x 7% x 5 = $245

Total value of the debt = $245 + $700 = $945

0.034518 = 3.45% probability that the proportion of tickets sold in a sample of 691 tickets would be less than 9%.

In a set with mean µ and standard deviation σ , the z score of a measure X is given by:

Z = X - µ/σ

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

For the sampling distribution of a sample proportion of size n, we have that

µ = √p(1-p)/n

p = 0.11, n = 691

so, µ= 0.11, σ= √0.11×0.89/691

σ = 0.011

What is the probability that the proportion of tickets sold in a sample of 691 tickets would be less than 9%?

This is the p value of Z when X = 0.09. So

Z = 0.09-0.11/0.011

Z = -1.8

Z = -1.8 has a p value of 0.034518

0.034518 = 3.45% probability that the proportion of tickets sold in a sample of 691 tickets would be less than 9%.

Solution:

The chemical formula for ammonium carbonate is (NH₄)₂CO₃. Therefore, option (C) is correct.

When heated, ammonium carbonate, also known as ()2, rapidly breaks down into ammonia and carbon dioxide. It functions as a smelling salt and a leavening agent. Ammonium carbonate, often known as baker's ammonia, was used before baking soda and baking powder as leaveners.

Sal volatile contains ammonium carbonate, and salt of hartshorn when baked emits a strong odour. At standard pressure and temperature, two processes lead to the gradual breakdown of ammonium carbonate. The pure ammonium carbonate sample will combine with different byproducts.

Upon spontaneous dissociation, ammonium carbonate can separate into ammonium bicarbonate and ammonia. which results in the addition of more ammonia, carbon dioxide, and water.

Step-by-step explanation:

As the sample size increases, the t-distribution becomes more concentrated around the mean, and there is less uncertainty about the population mean.

The t-distribution is a probability distribution that is used in statistical inference to test hypotheses about the mean of a population when the sample size is small and the population standard deviation is unknown. The shape of the t-distribution depends on the degrees of freedom (df), which is determined by the sample size.

When the degrees of freedom are small, the t-distribution has more probability mass in the tails and is more spread out than when the degrees of freedom are large. As the degrees of freedom increase, the t-distribution approaches the standard normal distribution, which has zero mean and unit variance.

In this case, we are comparing the t-distributions for df = 4 and df = 20. Since df = 4 is smaller than df = 20, the t-distribution for df = 4 is flatter and more spread out than the t-distribution for df = 20. This means that the tails of the distribution are fatter and there is more variability in the data for df = 4 than for df = 20. In other words, when the sample size is small, there is more uncertainty about the population mean, and it is more likely that the sample mean will be farther away from the true population mean.

The proportion has increased from 48% in 2013 to 50.4% in 2018.

i. State the hypotheses:

Let p be the proportion of social media site users who get their news about world events on the site. The null hypothesis is that there has been no change in the proportion since 2013, or:

H0: p = 0.48

The alternative hypothesis is that there has been a change in the proportion since 2013, or:

Ha: p ≠ 0.48

ii. Verify the CLT conditions and summarize the data with the test statistic:

The conditions for the Central Limit Theorem (CLT) are satisfied since the sample size is large enough (n=3625) and the sample is randomly selected.

The sample proportion of users who get their news about world events on the site is:

P = 1830/3625 = 0.504

The test statistic for the hypothesis test is:

z = (P- p) / sqrt(p*(1-p)/n) = (0.504 - 0.48) / sqrt(0.48*0.52/3625) = 4.33

iii. Assess the evidence by calculating the p-value of the test:

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed one, assuming the null hypothesis is true. The p-value for the test is:

p-value = P(|Z| > 4.33) = 2 * P(Z > 4.33) ≈ 0

The p-value is very small, indicating strong evidence against the null hypothesis.

iv. Conclude and interpret based on the results:

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of social media site users who get their news about world events on the site has changed since 2013. Specifically, the proportion has increased from 48% in 2013 to 50.4% in 2018.

By using the rule of 3 simple, we will see that the value of the angle of the arc is 30°.

We know that an arc of 24 degrees has an arc length of 28cm, then we can write a relation:

24° = 28cm

(notice that it is just a relation so we can use the 3-simple-rule, that is not an equation, we only can do this because there is a linear relation between the angle and the length).

And for an angle x we have a length of 35cm, then we can write:

x = 35cm

Now we can take the quotient of these two equations to get:

x/24° = (35cm/28cm)

Solving for x:

x = (35cm/28cm)*24° = 30°

That is the angle of the arc.

Wally would need  41.67 yards of fencing.

From the attached figure we can observe that the fencing to the back yard of his house would be rectangular.

Let us assume that the length of the fence is represented by l and width is represented by w.

Here, the back wall of Wally's house measures 15 yards.

15 yards = 45 ft

so, the length of the fence would be,

l = 5 + 45 + 3

l = 53 ft

and the width is 10 ft

The required fencing would be equal to the perimeter of this rectangle.

Using the formula for the perimeter of rectangle,

P = 2(l + w)

P = 2(53 + 10)

P = 125 ft

P = 41.67 yards

Thus, the required fencing = 41.67 yards
