The recent study says 24% wage gap between nonmetropolitan and metropolitan workers can be attributed to differences in job opportunities, education and skill levels, cost of living, and economic development.

According to a recent study, the median earnings of nonmetropolitan workers in the United States was 24% less than the median earnings of metropolitan workers.

The most likely explanation for this phenomenon can be attributed to several factors.
1. Job opportunities: Metropolitan areas tend to have a higher concentration of job opportunities, particularly in higher-paying industries such as finance, technology, and professional services.

In contrast, nonmetropolitan areas often have fewer job options and may be dominated by lower-paying industries such as agriculture, retail, and hospitality.
2. Education and skill levels: Metropolitan areas generally have a larger pool of highly educated and skilled workers, which can lead to higher salaries.

Nonmetropolitan areas may have lower levels of education and skill among the workforce, which can result in lower earnings.
3. Cost of living: The cost of living is generally higher in metropolitan areas, which can lead to higher salaries to offset these expenses.

In nonmetropolitan areas, the cost of living is typically lower, which can result in lower wages as employers do not need to pay as much to maintain a reasonable standard of living for their workers.
4. Economic development: Metropolitan areas tend to have more robust economies with higher levels of economic development.

This can create a more competitive job market, which can lead to higher salaries for workers. Nonmetropolitan areas often have less economic development, which can result in fewer high-paying jobs and lower wages overall.
In summary, the 24% wage gap between nonmetropolitan and metropolitan workers can be attributed to differences in job opportunities, education and skill levels, cost of living, and economic development.

These factors contribute to the higher median earnings of metropolitan workers compared to their nonmetropolitan counterparts.

We can check this using Pythagoras' theorem.

Explain Pythagoras' theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship in Euclidean geometry between the three sides of a right triangle. It asserts that the area of the square with the hypotenuse (the side opposite the right angle) equals the sum of the areas of the squares with the other two sides. This theorem may be expressed as an equation linking the lengths of the legs a, b, and the hypotenuse c, which is known as the Pythagorean equation: a² + b² = c²

According to Pythagoras' theorem, as we see a² + b² = c²

6² + 8² = 10², so the photo frame is still a rectangle.

The elapsed time between a start time of 6:28 am and an end time of 10:08 am is 3 hours and 40 minutes.

To calculate the elapsed time between a start time of 6:28 am and an end time of 10:08 am, we need to subtract the start time from the end time. First, let's consider the minutes. The end time is 08 minutes past the hour, and the start time is 28 minutes past the hour. Subtracting 08 minutes from 28 minutes gives us 20 minutes.

Next, let's consider the hours. The end time is 10:08 am, and the start time is 6:28 am. Subtracting the hours, we get 10 - 6 = 4 hours. Therefore, the elapsed time between the start time of 6:28 am and the end time of 10:08 am is 4 hours and 20 minutes. In other words, from 6:28 am to 10:08 am, there is a total of 4 hours and 20 minutes that have passed.

The number of different ways that 11 books can be arranged on a bookshelf is 39,916,800.

To determine the number of ways the 11 books can be arranged on a bookshelf, we can use the formula for permutation, which is given by:

P(n,r) = n!/(n-r)!

Where n is the total number of items and r is the number of items selected. In this case, we have 11 books and we want to arrange them all, so r = 11.

Therefore, the number of different ways the 11 books can be arranged on a bookshelf is:

P(11,11) = 11!/(11-11)! = 11! = 39,916,800.

This means that there are 39,916,800 different possible ways to arrange the 11 books on the bookshelf.

The margin of error at a 99% confidence level is 8.36.

The margin of error at a 99% confidence level based on a larger sample of 275 observations is 4.14.

a. Yes, the condition that X−X− is normally distributed is satisfied for a sample size of 69 by the central limit theorem.

b. The margin of error at a 99% confidence level can be computed using the formula:

Margin of error = z* (sigma / sqrt(n))

where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.

The z-score for a 99% confidence level is 2.576 (from the z table).

Substituting the given values, we get:

Margin of error = 2.576 * (27.5 / sqrt(69)) = 8.36

c. The margin of error at a 99% confidence level based on a larger sample of 275 observations can be computed using the same formula:

Margin of error = z* (sigma / sqrt(n))

where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.

The z-score for a 99% confidence level is still 2.576 (from the z table).

Substituting the given values, we get:

Margin of error = 2.576 * (27.5 / sqrt(275)) = 4.14

d. The margin of error is inversely proportional to the square root of the sample size. As the sample size increases, the margin of error decreases. Therefore, the margin of error with n = 275 will be smaller than the margin of error with n = 69, leading to a narrower confidence interval.

The sum of angle in a triangle is 180°

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC.

The sum of angle A, B and C is 180 i.e A+B +C = 180°

Also a triangle is a 3 sided polygon. The sum of of angle in a polygon is( n-2)180

How do we prove that the sum of angle in a triangle is 180°?

Since triangle is 3 sided, n= 3, because n denote the number if sides

therefore the sum of angle = (n-2) 180 = (3-2)×180

= 180°

therefore the sum of angle In a triangle is 180°

Answer:

The required sample size is 347

Step-by-step explanation:

The required sample size can be calculated as follows

Since we use 95% confidence interval, then the z critical for 95% is 1.96.

The formula to calculate the sample size is derived from the formula of 95% confidence interval for a mean

\(\overline{X} \pm 1.96 \frac{s}{\sqrt{n}}\)

Where \(\overline{X}\) is the point estimate or the value, computed from sample information, that is used to estimate the population parameter

s is the sample standard deviation

n is the sample size

Since the task say that the estimation of the population mean is within a sampling error of plus or minus 2 then substitute 2 for margin of error

\(\overline{X} \pm 1.96 \frac{s}{\sqrt{n}}\)

\(\overline{X} \pm\) 2

From the above expression, then the equation to follow is

\(2 = 1.96 \frac{s}{\sqrt{n}}\)

Divide both sides by  1.96 to isolate  \(\frac{s}{\sqrt{n}}\)

\(\frac {2}{1.96}=\frac{s}{\sqrt{n}}\)

Simplify the left side of the equation

\(\frac {2}{1.96}=\frac{s}{\sqrt{n}}\)

\(1.02041=\frac{s}{\sqrt{n}}\)

Substitute 19 for s

\(1.02041=\frac{19}{\sqrt{n}}\)

Multiply both sides by  \(\sqrt{n}\\\)

\(1.02041\sqrt{n}=19\)

Divide both side by 1.02041 to isolate \(\sqrt{n}\\\)

\(\sqrt{n}=\frac{19}{1.02041}\)

\(\sqrt{n}=18.612\)

Square both side to get the value of n

n = 346.41

We round up to determine that the required sample size is n = 347

If z is a standard normal variable, find P(z > 0.97). Round to four decimal places is option B: 0.1922.

To arrive at this answer, we first need to understand what a standard normal variable is. A standard normal variable is a random variable that has a normal distribution with a mean of 0 and a standard deviation of 1. This means that the distribution of values that the variable can take follows a bell-shaped curve, with most values being close to 0 and fewer values further away from 0 as we move towards the extremes.

In this case, we are asked to find the probability that the standard normal variable z is greater than 0.97. This means we are looking for the area under the bell-shaped curve to the right of 0.97.

We can use a table of standard normal probabilities, such as the Z-table, to find this probability. The Z-table provides the probability that a standard normal variable is less than or equal to a certain value. To find the probability that z is greater than 0.97, we need to subtract the probability that z is less than or equal to 0.97 from 1.

Looking up 0.97 in the Z-table, we find that the probability that z is less than or equal to 0.97 is 0.8340. Subtracting this value from 1, we get 0.1660. However, we need to round this value to four decimal places as per the instructions, which gives us 0.1660.

Therefore, the correct answer is not A or D, but B: 0.1922.

Step-by-step explanation:

Answer:

46

Step-by-step explanation:

An estimate of the number of employees who read at least one book per month is 432.

Based on the circle graph, out of the 50 employees surveyed:

19 employees read one book per month

7 employees read two books per month

10 employees read three or more books per month

14 employees do not read any books per month

To estimate the number of employees who read at least one book each month among the 600 employees of the company, we can use proportional reasoning.

The proportion of employees surveyed who read at least one book per month is:

(19 + 7 + 10) / 50 = 36 / 50 = 0.72

We can assume that this proportion is roughly the same for the entire company, so we can estimate the number of employees who read at least one book per month as:

0.72 x 600 = 432

Therefore, there are 432 workers, on average, who read at least one book each month.

We can use the given Matlab code with the function f(x) to find the minimum of the given function \(f(x) = 24 +223 + 7x^2 + 5x\) using the golden ratio search method.

The golden ratio, often denoted by the Greek letter phi (φ), is a mathematical concept that describes a ratio found in various natural and aesthetic phenomena. It is approximately equal to 1.618 and is often considered aesthetically pleasing. It is derived by dividing a line into two unequal segments such that the ratio of the whole line to the longer segment is the same as the ratio of the longer segment to the shorter segment.

Given: The function \(f(x) = 24 +223 + 7x^2 + 5x\), and Xi = -2.5, i = 2.5

We can use the golden ratio search method for finding the minimum of f(x).

The Golden ratio is a mathematical term, represented as φ (phi).

It is a value that is exactly 1.61803398875.The Matlab code for the golden ratio search method can be given as:

Function [a, b] =\(golden_search(f, a0, b0, eps) tau = (\sqrt{5}  - 1) / 2;\)

\(% golden ratio k = 0; a(1) = a0; b(1) = b0; L(1) = b(1) - a(1); x1(1) = a(1) + (1 - tau)*L(1); x2(1) = a(1) + tau*L(1); f1(1) = f(x1(1)); f2(1) = f(x2(1));\)

\(while (L(k+1) > eps) k = k + 1; if (f1(k) > f2(k)) a(k+1) = x1(k); b(k+1) = b(k); x1(k+1) = x2(k); x2(k+1) = a(k+1) + tau*(b(k+1) - a(k+1)); f1(k+1) = f2(k); f2(k+1) = f(x2(k+1));\)

\(else a(k+1) = a(k); b(k+1) = x2(k); x2(k+1) = x1(k); x1(k+1) = b(k+1) - tau*(b(k+1) - a(k+1)); f2(k+1) = f1(k); f1(k+1) = f(x1(k+1)); end L(k+1) = b(k+1) - a(k+1); end.\)
