The mean absolute deviation of the population is:

1.50 million

Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. The formula for MAD is:

MAD =∑|x-m|/n

∑ is known as Sigma and means to sum up

| | are vertical bars that mean absolute value

x is each value

m is the mean

n is the total number of data points in your data set

n = 10

m = (1.5 + 3.8 + 1.3 + 1.6 + 2.9 + 1.4 + 0.9 + 2.3 + 8.4 + 1.3)/10

   = 25.4/10

   = 2.54

∑|x-m| = |1.5-2.54| + |3.8-2.54| + |1.3-2.54| + |1.6-2.54| + |2.9-2.54| + |1.4-2.54| +|0.9-2.54| + |2.3-2.54| + |8.4-2.54| + |1.3-2.54|

From the question, we have the following parameters that can be used in our computation:

f(x) = x⁴ - 12x³ + 48x²

g(x) = 44x + 105

With the use of graphs, the curves intersect ar

x = -1 and x = 5

So, the area of the regions between the curves is

Area = ∫x⁴ - 12x³ + 48x² - 44x - 105

This gives

Area = ∫x⁴ - 12x³ + 48x² - 44x - 105

Integrate the expression

Area =  x * (x⁴ - 15x³ + 80x² - 110x - 525)/5

Recall that x = -1 and x = 5

So, we have

Area =  (-1) * ((-1)⁴ - 15(-1)³ + 80(-1)² - 110(-1) - 525)/5  - (5) * ((5)⁴ - 15(5)³ + 80(5)² - 110(5) - 525)/5

Point K is located at 3.5 on the number line.

To find point K on the number line, we need to apply the ratio LK to KM, which is 6:3. First, we can simplify this ratio to 2:1.

Next, we will find the total distance between points L and M. The distance LM = 6.5 - (-2.5) = 9 units.

Now, we can divide this distance into 3 equal parts, as per the simplified ratio 2:1. Each part will be 9/3 = 3 units long.

Since LK is 2 parts of the ratio, we will multiply the length of one part (3 units) by 2. LK = 3 * 2 = 6 units.

The cost of covering 1 unit² should be $2.477 to be in the budget and the total area to be covered is 3027.22 ft².

Given is a blueprint we need to find area that be covered and then the cost of covering the area,

So, we will find the area by splitting the figure into different shapes,

So the area =

Ar(rectangle) + Ar(semicircle) + Ar(triangle) + Ar(square)

= 9×3 + 3.14×2²/2 + 1/2×3×1 + 3³

= 27 + 6.28 + 1.5 + 27

= 61.78 units²

Since 1 unit = 7 ft

So, 1 unit² = 49 ft²

therefore, 61.78 units² = 61.78 × 49 = 3027.22 ft²

Since our budget is $7500

Costing of covering the area = 3027.22 × x = 7500

x = $2.477

Hence the cost of covering 1 unit² should be $2.477 to be in the budget.

The equation represents a cosine function that is horizontally shifted, vertically shifted, and scaled with specific values for amplitude, period, phase shift, and midline adjustment.

The equation and description of the interactive widget graph. It appears that the equation you've shared represents a periodic function, specifically a cosine function, with some transformations applied to it.

The general form of a cosine function is given by:

f(x) = A * cos(Bx - C) + D

In your equation, the parameters have specific values:

A = 2

B = 5π/5 = π

C = 5/(2π) = 5/2π

D = -4

The parameter A determines the amplitude of the cosine function, which controls the vertical range of the graph. In this case, it is 2, so the graph will oscillate between 2 units above and 2 units below the midline.

The parameter B affects the period of the function. Since B = π, the period of the cosine function will be 2π/B = 2π/π = 2. This means that the graph completes one full cycle (i.e., goes through one peak and one trough) over an interval of length 2.

The parameter C introduces a phase shift or horizontal translation to the graph. The value of C, 5/2π, determines how much the graph is shifted horizontally. Specifically, it is shifted 5/(2π) units to the right.

The parameter D is the vertical shift or midline adjustment. With D = -4, the entire graph is shifted downward by 4 units.

The movable point mentioned in the widget likely allows you to change the value of x and observe how it affects the position of the extremum point and the intersection points with the midline.

Overall, the equation represents a cosine function that is horizontally shifted, vertically shifted, and scaled with specific values for amplitude, period, phase shift, and midline adjustment.

The weights of equity, debt, and preferred stock, based on the market value of each component, of Linge burger Cheese Corporation, are as follows:

Firstly, we calculate the market value of each capital component and divide the result by the total market value of the firm.  This process determines the weights of equity, debt, and preferred stock.

The market value of equity is the number of shares outstanding multiplied by the current share price.

Number of shares outstanding = 6.4 million

Market value per share = $54

Common stock beta = 1.08

Market value = $345.6 million (6.4 million × $54)

Number of shares outstanding at $100 par value = 200,000

Market value per share  = $103

Market value = $20.6 million (200,000 × $103)

Number of bonds outstanding, par value $1,000 each = 120,000

Maturity period of bonds = 15 years

Market value per bond = 107 percent of par

Market value of debt = $128.4 million (120,000 × 1.07 × $1,000)

T-bill yields = 2.4%

Corporate tax rate = 22%

Total market value = $494.6 million ($345.6 million + $20.6 million + $128.4 million)

Weight of equity = 0.6987 or 69.87% ($345.6 million ÷ $494.6 million)

Weight of preferred stock = 0.0417 or 4.17% ($20.6 million ÷ $494.6 million)

Answer: Let's use the following variables to represent the amount of vitamin C in an eight-ounce glass of each type of juice:

A: amount of vitamin C in an eight-ounce glass of apple juice (in milligrams)

O: amount of vitamin C in an eight-ounce glass of orange juice (in milligrams)

Using this, we can set up a system of two equations based on the given information:

Equation 1: A + O = 187.7 (total vitamin C in two glasses)

Equation 2: 3A + 4O = 651.4 (total vitamin C in three glasses of apple juice and four glasses of orange juice)

We can solve for one of the variables in terms of the other by rearranging Equation 1:

A = 187.7 - O

Substituting this expression for A into Equation 2, we get:

3(187.7 - O) + 4O = 651.4

Simplifying and solving for O, we get:

563.1 - 3O + 4O = 651.4

O = 88.3

Therefore, an eight-ounce glass of orange juice contains 88.3 milligrams of vitamin C. To find the amount of vitamin C in an eight-ounce glass of apple juice, we can substitute this value into Equation 1:

A + 88.3 = 187.7

A = 99.4

So, an eight-ounce glass of apple juice contains 99.4 milligrams of vitamin C.

The numerator (3 1/5) is greater than the denominator (4), so the unit rate is greater than 1.

7 1/10 pounds : 9/10 pound:

The numerator (7 1/10) is greater than the denominator (9/10), so the unit rate is greater than 1.

7/8 pound : 2 pounds:

The numerator (7/8) is less than the denominator (2), so the unit rate is not greater than 1.

9/4 pounds : 3/4 pound:

The numerator (9/4) is greater than the denominator (3/4), so the unit rate is greater than 1.

3 pounds : 1 1/2 pounds:

The numerator (3) is equal to the denominator (1 1/2), so the unit rate is not greater than 1.

2 pounds : 1/3 pound:

The numerator (2) is greater than the denominator (1/3), so the unit rate is greater than 1.

Therefore, the ratios with unit rates greater than 1 are:
