In each scenario, the choice between mean and median as a representative measure of central tendency depends on the nature of the data and the specific context..

1. Scenario: Income distribution of a population

- If the income distribution is skewed or contains extreme values (outliers), the median would be a better representation of the central tendency. This is because the median is not influenced by outliers and provides a more robust estimate of the "typical" income level. However, if the income distribution is approximately symmetric without outliers, the mean can also be an appropriate measure.

2. Scenario: Exam scores in a class

- If the exam scores are normally distributed without significant outliers, the mean would be a suitable measure as it takes into account the value of each score. However, if there are extreme scores that deviate from the majority of the data, the median may be a better representation. This is especially true if the outliers are indicative of errors or exceptional circumstances.

3. Scenario: Housing prices in a city

- In this case, the median would be a more appropriate measure to represent the central tendency of housing prices. This is because the housing market often exhibits a skewed distribution with a few high-priced properties (outliers). The median, being the middle value when the data is sorted, is not influenced by these extreme values and provides a better understanding of the typical housing price in the city.

Ultimately, the choice between mean and median depends on the specific characteristics of the data and the objective of the analysis. It is important to consider the distribution, presence of outliers, and the context in which the data is being interpreted.

The phase change line, also known as the phase boundary or phase transition line, is a line on a graph that represents a change in conditions for a substance. This line shows the temperature and pressure conditions at which a substance will change from one phase to another, such as from a solid to a liquid or from a liquid to a gas.

The phase change line is represented on a graph by a diagonal line that separates two regions where the substance is in different phases. This line usually slopes upwards from left to right, indicating that higher temperatures and pressures are needed to change the substance from one phase to another.

The phase change line is an important concept in thermodynamics and is used to understand the behavior of substances under different conditions. For example, the phase change line for water shows that at normal atmospheric pressure, water will freeze at 0°C and boil at 100°C. However, at higher pressures, the freezing and boiling points will change, and water may exist in different phases, such as a supercritical fluid.

The MAD of the hourly wages given would be $ 0.48. The range would be $ 2.00. Q1 would be $8.25. Q3 would then be $9.25. The IQR would be $1.00

Calculate the MAD:

First, find the mean of the data set:

mean = (sum of all values) / (number of values)

mean = (8.25 + 8.50 + 9.25 + 8.00 + 10.00 + 8.75 + 8.25 + 9.50 + 8.50 + 9.00) / 10

mean = 88.00 / 10 = 8.80

Then, find the mean of these absolute deviations:

MAD = (sum of absolute deviations) / (number of values)

MAD = (0.55 + 0.30 + 0.45 + 0.80 + 1.20 + 0.05 + 0.55 + 0.70 + 0.30 + 0.20) / 10

MAD = 4.10 / 10 = 0.41

Calculate the range:

range = maximum value - minimum value

range = 10.00 - 8.00 = 2.00

Find Q1 and Q3:

{8.00, 8.25, 8.25, 8.50, 8.50, 8.75, 9.00, 9.25, 9.50, 10.00}

Q1 is the median of the lower half, and Q3 is the median of the upper half.

Lower half: {8.00, 8.25, 8.25, 8.50, 8.50}

Upper half: {8.75, 9.00, 9.25, 9.50, 10.00}

Q1 = median of lower half = 8.25

Q3 = median of upper half = 9.25

The missing side of triangle is 13.3 yd.

What is Pythagorean Theorem?

The Pythagorean theorem, also known as Pythagoras' theorem, is a basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of the square with the hypotenuse side is equal to the sum of the areas of the squares with the other two sides.

There are two sides of triangle are given.

We have to find the missing side of triangles.

Let x be the missing side of triangles.

By using Pythagorean theorem,

(10.3)^2 + (8.4)^2 = x^2

 106.09 + 70.56 = x^2

               176.55 = x^2

                    13.3 = x

                        x = 13.3

1 Pound of bananas cost $0.39

Step-by-step explanation:

Answer:

just divide 1.56 by 4

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Using the fundamental theorem of arithmetic, we have proven that (a, 6) [a, b] = ab for positive integers a and b.

To prove that (a, 6) [a, b] = ab for positive integers a and b using the fundamental theorem of arithmetic, we'll proceed as follows:

Step 1: Prime factorization of a and 6:

Using the fundamental theorem of arithmetic, we can write a and 6 as products of their prime factors:

a = p1^k1 * p2^k2 * ... * pn^kn,

6 = 2^1 * 3^1.

Step 2: Finding the greatest common divisor (a, 6):

To find the greatest common divisor (a, 6), we consider the common prime factors between a and 6 and take the minimum exponent for each prime factor. In this case, the common prime factor is 2 with an exponent of 1. Therefore, (a, 6) = 2^1.

Step 3: Prime factorization of [a, b]:

Using the fundamental theorem of arithmetic, we can write [a, b] as a product of its prime factors:

[a, b] = p1^m1 * p2^m2 * ... * pn^mn.

Step 4: Finding the least common multiple [a, b]:

To find the least common multiple [a, b], we consider the prime factors between a and b and take the maximum exponent for each prime factor. In this case, we have already determined that the common prime factor is 2 with an exponent of 1. Therefore, [a, b] = 2^1.

Step 5: (a, 6) [a, b] = ab:

Substituting the values we found, we have:

(a, 6) [a, b] = 2^1 * 2^1 = 2^2 = 4.

Since ab = 4, we have proven that (a, 6) [a, b] = ab for positive integers a and b using the fundamental theorem of arithmetic.

The length of a rectangular sandbox is

6 feet less than 3 times the width. The perimeter of the sandbox is 36 feet.

Which statement is true?

a) The equation (3w − 6) +w = 36

can be used to find the width of the rectangle, and the width is 6 feet.

b) The equation(3w −6) + w =36

can be used to find the width of the rectangle, and the width is 12 feet.

c) The equation 2(3w − 6) + 2w = 36

can be used to find the width of the rectangle, and the width is 6 feet.

d) The equation 2(3w − 6) +2w = 36

can be used to find the width of the rectangle, and the width is 12 feet.

Answer:

Option c) is true

The equation 2(3w − 6) + 2w= 36

can be used to find the width of the rectangle, and the width is 6 feet.

Step-by-step explanation:

The length of a rectangular sandbox is

6 feet less than 3 times the width. The perimeter of the sandbox is 36 feet.

L = 3 × W - 6

L = 3W - 6

The formula for perimeter of a rectangle = 2(L + W)

= 2L + 2W

Hence, we substitute

P = 2L+ 2W

36 = 2(3W - 6) + 2W

36 = 6W -12 + 2W

Collect like terms

36 +12 = 6W + 2W

48 = 8W

W = 48/8

W = 6

The width is 6 feet

Which statement is true?

Option c) is true

The equation 2(3w − 6) + 2w= 36

can be used to find the width of the rectangle, and the width is 6 feet.

Correct option is B. Mrs. Quabarl is best described as outwardly imposing but easily defied.

Mrs. Quabarl is very vocal about her demands and imposing in her wishes as stated in the passage. But she is also docile and surprised when she is defied, though she speaks nothing of it.

Answer:

r = 5.848cm, h = 11.696cm

Step-by-step explanation:

Surface area: \(SA=2\pi rh+2\pi r^2\)

Volume: \(V=\pi r^2h\)

Therefore, the height of a cylinder given its volume would be \(h=\frac{V}{\pi r^2}\), thus:

\(SA=2\pi r(\frac{V}{\pi r^2})+2\pi r^2\\\\SA=\frac{2V}{r}+2\pi r^2\\\\SA=\frac{2(400\pi)}{r}+2\pi r^2\\\\SA=\frac{800\pi}{r}+2\pi r^2\)

We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:

\(\frac{d(SA)}{dr}=-\frac{800\pi}{r^2}+4\pi r\)

\(0=-\frac{800}{r^2}+4\pi r\)

\(0=800\pi+4\pi r^3\)

\(-800\pi=4\pi r^3\)

\(-200=r^3\)

\(r\approx5.848\)

If \(0If \(r>5.848\), then the surface area of the cylinder increases

Therefore, the surface area is minimized when the radius is \(r=5.848cm\), making the minimum height \(h=\frac{V}{\pi r^2}=\frac{400\pi}{\pi(5.848)^2}\approx11.696cm\).

In conclusion, the 2nd option is correct.
