The demand function of the question is expressed as;

D(q) = -²/₅₀₀₀q + 14.6

The formula to find the slope between two coordinates is;

m = (y2 - y1)/(x2 - x1)

The coordinates we are given are;

(28000, 9) and (33000, 7)

Thus;

Slope; m = (7 - 9)/(33000 - 28000)

m = -2/5000

Now, the equation of a line in point slope form is;

y - y1 = m(x - x1)

Where (x1, y1) is (28000, 9)

y - 9 = (-2/5000)(x - 28000)

y - 9 = -²/₅₀₀₀x + 5.6

Note that the Upper limit and the lower limit of the Proportion Interval are given as follows:

Upper limit-  27%

Lower limit - 19%

The proportion interval, also known as the confidence interval, can be calculated using the point estimate of the proportion and the margin of error.

The lower limit of the proportion interval is calculated by subtracting the margin of error from the point estimate, and the upper limit is calculated by adding the margin of error to the point estimate.

Lower limit = point estimate - margin of error

Upper limit = point estimate + margin of error

In this case, the point estimate is 23% and the margin of error is ±4%.

Lower limit = 23% - 4% = 19%

Upper limit = 23% + 4% = 27%

Therefore, the proportion interval is [19%, 27%], which means that we can be 90% confident that the true proportion of the population lies within this range.

The population increased by 18 million at the end of one year at the rate of 1.8%.

The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. Alternatively put, it is the relationship between a component and a whole in which the value of "whole" is always assumed to be 100.

For instance, if a student receives 15 out of 50 in math, one can determine the relevant percentage by expressing "marks earned" as a fraction of "total marks" and multiplying the result by 100. i.e., the percentage of marks is equal to 15 / 50 100, or 30%.

Given that, population of India is one billion.

The rate of increase is 1.8%.

After one year the population will be:

P = (1000000000)(1.8/100)

P = 18000000

Hence, the population increased by 18 million at the end of one year at the rate of 1.8%.

Explanation:

Let's go through each answer choice to see which are true and which are false.

A.

The fractions for advertising and rent are 1/6 and 7/12 respectively. The LCD is 12, so let's get 1/6 to have a denominator of 12. Multiply top and bottom by 2 to get 1/6 = 2/12.

Now we can compare the fractions 2/12 (aka 1/6) and 7/12. Clearly 7/12 is larger. It's like saying "having 7 slices of pizza is more than 2 slices of pizza". Therefore, the claim that more was spent on advertising compared to rent is false.

----------------------

B.

1/4 = 3/12 when multiplying top and bottom by 3

3/12 was spent on supplies and 2/12 was spent on advertising

We see that more was spent on supplies, so claim B is true

----------------------

C.

This claim is false because it contradicts claim B.

Another way to see why it's false is to use a calculator to get these decimal values

Since 0.17 is not larger than 0.25, this means 1/6 is not larger than 1/4.

----------------------

D.

We could use any of the methods mentioned in the previous sections, but I'll go another route.

For now assume that the fractions for supplies and rent (1/4 and 7/12 respectively) are equal.

Let's use cross multiplication to say the following:

1/4 = 7/12

1*12 = 4*7

12 = 28

Clearly the two sides are different so the original fractions aren't equal. To fix this error, replace each equal sign with a "less than" sign like so

1/4 < 7/12

1*12 < 4*7

12 < 28

Think of it like working backward up the chain. Start with 12 < 28 which is clearly true, and you can work backwards to end up with 1/4 < 7/12.

The fact we end up with 1/4 < 7/12 shows the claim "The bookstore spends more on supplies than rent" is false. It's the other way around: the bookstore spent more on rent compared to supplies.

----------------------

The value of x when an angle of the given figure is given as 9x - 3 is x = 5.

Given a figure.

It is required to find the value of x.

Here, consider the two triangles which are split up in the figure.

Consider the triangles JKL and JML.

Comparing the sides and angles:

JK = JM

KL = ML

JL = JL

So, they are similar.

Each corresponding angles are equal.

Here, the angle corresponding to ∠JLK is ∠JLM.

So, they are equal.

∠JLM = ∠JLK

9x - 3 = 42

Add 3 on both sides.

9x = 45

Divide both sides by 9.

The approximate margin of error for a survey based on 2,700 adults, when rounded to nearest thousand is 0.021.

In statistical surveys, the margin of error is a measure of the expected amount of random sampling error that is present in a survey's results. It is a range of values that is likely to contain the true value of the population parameter being estimated, with a certain degree of confidence.

In other words, the margin of error is the amount by which the sample estimate may differ from the true value of the population parameter.

The margin of error is affected by several factors, such as the size of the sample and the level of confidence. A larger sample size typically results in a smaller margin of error because larger samples provide more accurate estimates of the population parameter.

Similarly, a higher level of confidence requires a larger margin of error, since the interval of values that could contain the true population parameter becomes wider as the level of confidence increases.

Assuming a 95% level of confidence, the formula for calculating the margin of error is:

Margin of error = z * sqrt(p * (1 - p) / n)

where:

z is the z-score for the desired level of confidence (1.96 for 95%)

p is the sample proportion, which is the proportion of the sample that exhibits a particular characteristic of interest (e.g., the proportion of respondents who support a certain political candidate)

n is the sample size, which is the number of observations in the sample.

If the sample proportion is not known, it is common to use a value of 0.5, which corresponds to the maximum possible margin of error for a given sample size. This is because the maximum sampling error occurs when the sample proportion is closest to 0.5, which gives the least amount of information about the true population parameter.

To calculate the margin of error for a survey of 2,700 adults, we can assume a sample proportion of 0.5 and a 95% level of confidence. Plugging these values into the formula, we get:

Margin of error = 1.96 * sqrt(0.5 * (1 - 0.5) / 2700)

= 1.96 * sqrt(0.25 / 2700)

= 1.96 * 0.008

= 0.016

Rounding to the nearest thousandth, the approximate margin of error is 0.021. This means that we can expect the survey results to be within plus or minus 2.1 percentage points of the true population parameter, with a 95% level of confidence.

Zion Sun Chairs must sell each chair for at least $75.21 to earn a monthly profit of $65,000.

To determine the minimum sales price Zion Sun Chairs must sell each chair for to earn a monthly profit of $65,000, we can use the following formula:

Total Profit = Total Revenue - Total Cost

We know that the monthly fixed costs are $17,363.50, and the variable cost per chair is $52.17. Therefore, the total cost to produce 3,575 beach chairs each month can be calculated as follows:

Total Cost = Fixed Cost + (Variable Cost per Chair x Number of Chairs)

Total Cost = $17,363.50 + ($52.17 x 3,575)

Total Cost = $203,871.25

To earn a monthly profit of $65,000, we can set up the equation as follows:

$65,000 = Total Revenue -  $203,871.25

Total Revenue =$268,871.25

To find the minimum sales price per chair, we can divide the total revenue by the number of chairs:

Minimum Sales Price per Chair = Total Revenue / Number of Chairs

Minimum Sales Price per Chair = $268,871.25 / 3,575

Minimum Sales Price per Chair ≈ $75.208
