The sum of the arithmetic series 5, 9, 13, 17, ..., (4n + 1) will be n(2n + 3) which is true.

Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.

Then the sum of the arithmetic sequence will be

Sₙ = (n / 2)[a₁ + L]

From the sequence, the first term is 5 and the last term is (4n + 1). Then the sum of the sequence is given as,

Sₙ = (n/2)(5 + 4n + 1)

Sₙ = (n/2)(4n + 6)

Sₙ = n (2n + 3)

Given a quadratic function y = 36 - x² , the intervals over which the function is increasing is: (-∞ , 0) and the intervals over which the function is decreasing is:  (0, ∞).

The standard form of a quadratic function is given by:

f(x) = ax² + bx + c

If a > 0, the graph of the function opens upward and the extreme point is the minimum one.

If a < 0, the graph of the function opens downward and the extreme point is the maximum one.

In this case, the function is: y = 36 - x²

Since the coefficient of the quadratic term is negative, or a < 0, then the graph opens downward and has a maximum point.

y = 36 - x²  is already in the form of perfect square, hence, we can immediately compute:

x-intercepts : (-6,0) and (6,0)

y-(intercept = maximum point = (0, 36)

Before the maximum point, the function is increasing, while after the maximum point, the function is decreasing.

Hence,

increasing interval = (-∞ , 0)

decreasing interval = (0, ∞)

By using the binominal model, the people in the sample are pessimistic about the future of marriage and family is 0.039.

A Binomial model is a mathematical model used to calculate the probability of a specific number of successful outcomes in a set number of trials

The normal model is used to compute the probability of a certain outcome occurring when the population size is much larger.

With a sample of 700 American adults, the probability of 25% or fewer of the people in the sample being pessimistic about the future of marriage and the family would be 0.039.

These answers demonstrate the importance of verifying that np and nq  are both at least 10.

If either one is below 10, the binomial model would not be an accurate representation of the probability.

On the other hand, the normal model does not have this limitation and can be used to calculate the probability even when np or nq is below 10.

a. To calculate the average daily sales over the course of seven days, multiply the total sales over the course of seven days by seven.

The salesperson generated $36,000 in revenue in the first three days by selling an average of $12,000 per day.

The following four days saw sales of $9,000 on average, for a total of $36,000 ($4 days * $9,000/day). Sales for the seven days added up to $36,000 + $36,000 = $72,000. Thus, throughout the course of the entire seven days, the average daily sales were $72,000 / seven days, or $10,285.7.

b. We must aggregate the total earnings from both jobs and divide it by the total number of hours worked in order to determine the average hourly wage. Kelly puts in a total of 12 hours of work by working 5 hours at a restaurant and 7 hours at a retail store. She is paid $12 per hour at the retail location and $20 per hour at the restaurant, so her total pay for seven hours is $104. The daily average hourly wage is $104 divided by 12 hours, or $8.67.

c. We must first calculate Henry's total earnings for the first 10 days, then deduct those earnings from the first 9 days to arrive at his earnings on the final day. The total income for the first 10 days was $1,200 (10 days * $120/day). Five days at a rate of $100 each brought in a total of $500. The next four days' earnings came to $520 (4 days * $130/day). For the first nine days, the total earnings were $500 + $520, or $1,020. Therefore, Henry's final day earnings were $180 ($1,200 – $1,020).

d. The number of singles, doubles, triples, and home runs must be added up in order to determine the total number of at-bats. Marcus has 107 hits overall, which include 18 singles, 33 doubles, 2 triples, and 54 home homers. He has now played in 107 at-bats.

e. The total bases (one base for a single, two bases for a double, three bases for a triple, and four bases for a home run) must be added together and divided by the total at-bats in order to determine the slugging percentage. Tyler has 235 total bases, which are calculated as follows: 74 singles * 1 base/single + 13 doubles * 2 bases/double + 11 triples * 3 bases/triple + 4 home runs * 4 bases/home run. His Slugging Percentage therefore equals 235 / 383 at-bats, or 0.616. Divide the total number of hits by the total number of at-bats to obtain the batting average. 383 at-bats x 74 hits Equals 0.193 for Tyler.

The 11th bee collected 2047 grams of pollen.

This can be determined by using a simple arithmetic progression. If the first bee collected 100 grams of pollen, the second bee collected more than twice that amount, or 1002 = 200 grams.

Then, the third bee collected more than twice the amount collected by the second bee, or 2002 = 400 grams. This pattern can be continued, and the 11th bee would have collected 1002^(10) = 1001024 = 104800 grams, or 104.8 kg of pollen.

The size of a Simple Random Sample (SRS) for estimating the mean score of medical college admissions test takers on your campus depends on the desired level of precision and the variability of the population.

The sample size required to estimate the mean score of a population depends on the desired level of precision, the variability of the population, and the level of confidence desired. In general, a larger sample size is needed to estimate the mean of a population with high variability or when a high level of precision is desired.

On the other hand, a smaller sample size is sufficient if the population is relatively homogeneous or if a lower level of precision is acceptable. It's important to note that a sample size that is too small may result in an imprecise estimate, while a sample size that is too large may be unnecessarily wasteful.

Median: Cannot be determined.

Mean: Increase.

Standard Deviation: Cannot be determined.

What are the mean, median, and standard deviation?

Standard deviation (σ) is defined as the square root of the variance. It measures the variability about the mean of a data set: the closer to the mean, the lower the standard deviation.

Median: Cannot be determined.

The median is the middle value in a set of data and can only change if the new value added to the menu is in the middle of the existing range.

If the new value is added to the beginning or end of the range, the median will remain unchanged.

Mean: Increase.

The mean is calculated by summing all the values and dividing by the number of values.

Adding a new value to the menu will increase the total sum and therefore increase the mean.

Standard Deviation: Cannot be determined.

The standard deviation measures the amount of variation or dispersion from the mean.

Adding a new value to the menu may increase or decrease the standard deviation, but it depends on the specific distribution of values in the existing menu and how the new value fits into that distribution.

Without more information, it is not possible to determine whether the standard deviation will increase, decrease, or remain unchanged.
