Answer:

\(-\dfrac{4}{5}\)

Step-by-step explanation:

We have the following expression

\(3 \;\dfrac{1}{2} x - 5\;\dfrac{1}{2}x\)

and asked to evaluate this expression at  \(\[x = {2\over\displaystyle 5\]\)

First convert \(3 \; \dfrac{1}{2}\)   and  \(5 \; \dfrac{1}{2}\)  to mixed fractions

\(3 \; \dfrac{1}{2} = \dfrac{3 \times 2 + 1}{2} = \dfrac{7}{2}\\\)

\(5 \; \dfrac{1}{2} = \dfrac{5 \times 2 + 1}{2} = \dfrac{11}{2}\)

Therefore
\(3 \;\dfrac{1}{2} x - 5\;\dfrac{1}{2}x\\\\= \dfrac{7}{2}x - \dfrac{11}{2}x\\\\= \dfrac{7 - 11}{2} x\\\\= -\dfrac{4}{2}x \\\\= -2x\\\\\)

\(\mathrm{For \;x =\dfrac{2}{5}},\\\\= -2x \\= - 2 \times \dfrac{2}{5}\\\\= -\dfrac{4}{5}\)

Annabeth's bi-weekly gross earnings, including overtime compensation, would be $1,097.56.

Amount is a term used to describe a quantity or size of something. It is used to refer to a number of objects, items, or people, as well as a measure of money, time, or distance. Amount is also used to describe the total sum of money that is owed, received, or spent.

This amount is calculated by multiplying her hourly rate of $21.84 (which is determined by dividing her bi-weekly gross earnings of $913.45 by 40 hours) by 47 hours, which is the total number of hours worked in the week. Then, her overtime compensation of 7 hours is multiplied by her hourly rate of $21.84 multiplied by 1.5, which is the rate for time-and-a-half. The sum of these two amounts is her bi-weekly gross earnings with overtime, which is $1,097.56.

Leaving the TV on for two weeks while on vacation would cost you approximately $4.46.

To calculate the cost, we need to determine the total energy consumed by the TV while you were on vacation and then convert it to dollars.

First, let's calculate the energy consumption in kilowatt-hours (kWh):

Power (in kilowatts) = Voltage (in volts) * Current (in amps) / 1000

Power = 120 V * 0.96 A / 1000 = 0.1152 kW

Now, we need to find the total energy consumed in kilowatt-hours (kWh) over the two-week period:

Energy (in kilowatt-hours) = Power (in kilowatts) * Time (in hours)

Energy = 0.1152 kW * 24 hours/day * 14 days = 38.4512 kWh

Next, let's calculate the cost of this energy consumption:

Cost = Energy (in kilowatt-hours) * Cost per kilowatt-hour

Cost = 38.4512 kWh * $0.116/kWh = $4.46 (rounded to two decimal places)

Therefore, leaving the TV on for two weeks while on vacation would cost you approximately $4.46.

The weighted average cost of capital (WACC) for company C is 6.63%.

The weighted average cost of capital (WACC) is a financial metric that represents the average rate of return a company must earn on its investments to satisfy its shareholders and creditors. It takes into account the proportion of debt and equity in a company's capital structure and the respective costs associated with each.

To calculate WACC, we need to consider the cost of debt and the cost of equity. The cost of debt is the interest rate a company pays on its debt, adjusted for taxes. In this case, the pre-tax cost of debt is 2% and the tax rate is 24%. Therefore, the after-tax cost of debt is calculated as (1 - Tax Rate) multiplied by the pre-tax cost of debt, resulting in 1.52%.

The cost of equity represents the return required by equity investors to compensate for the risk associated with owning the company's stock. Here, the cost of equity for company C is 6%.

The debt represents 10% of the total capital, while the equity represents the remaining 90%. To calculate the weighted average cost of capital (WACC), we multiply the cost of debt by the proportion of debt in the capital structure and add it to the cost of equity multiplied by the proportion of equity.

WACC = (Proportion of Debt * Cost of Debt) + (Proportion of Equity * Cost of Equity)

In this case, the calculation is as follows:

WACC = (0.10 * 1.52%) + (0.90 * 6%) = 0.152% + 5.4% = 6.552%

Therefore, the weighted average cost of capital (WACC) for company C is approximately 6.63%.

The central angle is the ratio of arc length and radius.

What is a Central Angle?

The central angle is the angle that a circle's arc occupies in its centre. The arms of the central angle are formed by the radius vectors. In other words, it's an angle whose vertex is the centre of a circle and whose arms, which have the circle's two radii as their arms, cross at two separate positions. These two points make an arc when they are combined. The angle that this arc at the circle's centre subtends is known as the central angle.

According to the central angle, we state that:

An arc's angle at the circle's centre is twice as large as its angle at any other point along the circle's circumference.

OR

The angle subtended by the arc in the opposite segment of the circle is twice as large as the angle at the centre of the circle.

Hence,

The central angle is the ratio of arc length and radius.

The value of p-hat (the sample proportion) is 0.24, or 24% if total number of skittles in a sample is 300 out of which 72 skittles are purple.

The sample proportion, denoted by p-hat, is the proportion of purple skittles in the sample. We can calculate p-hat by dividing the number of purple skittles by the total number of skittles in the sample

p-hat = number of purple skittles / total number of skittles in sample

In this case, we have

Number of purple skittles = 72

Total number of skittles in sample = 300

Therefore,

p-hat = 72/300 = 0.24

The sides of the quadrilateral arranged from longest to shortest are CD, AB, DA, and BC.

We have,

To arrange the length of the sides of the quadrilateral from longest to shortest, we need to calculate the length of each side of the quadrilateral using the distance formula:

Distance Formula:

If (x1, y1) and (x2, y2) are two points in a plane, then the distance between them is given by:

d = √((x2 - x1)² + (y2 - y1)²)

Using the distance formula, we can calculate the length of each side of the quadrilateral as follows:

AB = √((4 - (-5))² + (5 - 5)²) = 9

BC = √((2 - 4)² + (0 - 5)²) = √(29)

CD = √((-5 - 2)² + (-2 - 0)²) = √(74)

DA = √((-5 - (-5))² + (5 - (-2))²) = 7

sqrt(2)/2

Step-by-step explanation:

Given tan(x)=2-cot(x), find sin(x).

Rewrite in terms of sine and cosine:

sin(x)/cos(x)=2-cos(x)/sin(x)

Multiply both sides by cos(x)sin(x):

sin^2(x)=2sin(x)cos(x)-cos^2(x)

Rewrite cos^2(x) using the identity sin^2(x)+cos^2(x)=1:

sin^2(x)=2sin(x)cos(x)-(1-sin^2(x))

Distribute:

sin^2(x)=2sin(x)cos(x)-1+sin^2(x)

Subtracting sin^2(x) on both sides:

0=2sin(x)cos(x)-1

Add 1 on both sides:

1=2sin(x)cos(x)

Use identity sin(2x)=2sin(x)cos(x) to rewrite right:

1=sin(2x)

Since sin(pi/2)=1, then 2x=pi/2.

Dividing both sides by 2 gives x=pi/4.

So sin(pi/4)=sqrt(2)/2

Answer:

Step-by-step explanation:

You want the median for each of the histograms shown.

The median value is the value of the independent variable that divides the area of the histogram into two equal parts. It can be found as the variable value corresponding to half of the cumulative sum of areas.

To find it, we can find half of the total of the area of the histogram. This locates the bar containing the dividing line. Then we find the median as the  variable value interpolated between the area before the bar and the area including the bar.

This histogram is completely symmetrical, so the median is the value of x halfway between the limits of the middle bar:

  (10 +15)/2 = 12.5

The median is x = 12.5.

If we consider an interval of width 5 to be "1 unit", multiplying the width by the heights of the bars gives the series of areas ...

  (0.2, 0, 0.9, 0.9, 0.5, 0.5, 0.8, 0.2}

The total is 4, so half that is 2. The calculator tells us the cumulative total area (working from the left) is 2 at x = 20.

The median is x = 20.

Again, we choose "1 unit" horizontally to be 5 kg. Then the bar heights are the areas of the bars. The cumulative area is 20, so half the area is 10.

The highest bar, between 65 and 70, has a cumulative area of 6.8 at its left side and 12.6 at its right side. Then the cumulative area will be 10 at the point that is (10 -6.8)/(12.6 -6.8) = 3.2/5.8 = 16/29 of the distance between 65 and 70. The value of weight (kg) there is ...

  (16/29)(70 -65) +65 ≈ 67.759 . . . . kg

The median weight is about 67.8 kg.

__

Additional comment

The calculator image shows a calculation of median weight that is essentially the same, but executed differently.

If a1 and a2 are the cumulative areas on either side of the bar containing the median, and x1 and x2 are the x-values on either side of that same bar, then the median x is calculated from the median area m as ...

  x = ((a2 -m)x1 +(m -a1)x2)/(a2 -a1)

We have chosen bars of equal width to form the cumulative sum of areas. That way, we only need to be concerned with the bar height in the interval. You could use actual area values, which requires you multiply height by width for each bar. The above formula still works for that case.

The quartile locations can be found in similar fashion. If you have very many of these to do, a spreadsheet or statistics application may be helpful.

Exercise 82: No solution for all values of "k".

Exercise 83: Infinitely many solutions for all values of "k".

Exercise 84: Infinitely many solutions for all values of "k".

Using the concept of the system of linear equations, we can determine the number of solutions for each exercise:

No solution:

Equations: x + ky = 2, kx + y = 4

For a unique solution, the slopes of the two lines formed by the equations should be different. In this case, the slopes are k and 1, respectively. Since a1/b1 = k/1 is not equal to a2/b2 = 1/k, there is no common slope. Therefore, for exercise 79, there is no solution for all values of "k".

Exactly one solution:

Equations: x + ky = 0, kx + y = 0

For exactly one solution, the slopes of the two lines formed by the equations should be different. In this case, the slopes are k and 1, respectively. Since a1/b1 = k/1 is not equal to a2/b2 = 1/k, the slopes are different. Therefore, for exercise 80, there is exactly one solution for all values of "k".

Infinitely many solutions:

Equations: kx + 2ky + 3kz = 4k, x + y + z = 0, 2x - y + z = 1

For infinitely many solutions, the slopes of the planes formed by the equations should be equal. In this case, a1/b1 = a2/b2 = 1/2 = c1/c2. Therefore, for exercise 81, there are infinitely many solutions for all values of "k".

No solution:

Equations: x + 2y + kz = 6, 3x + 6y + 8z = 4

For a unique solution, the slopes of the planes formed by the equations should be different. In this case, a1/b1 = 1/2 is not equal to a2/b2 = 3/6 = 1/2. Therefore, for exercise 82, there is no solution for all values of "k".

Infinitely many solutions:

Equations: 4x + ky = 6, kx + y = -3

For infinitely many solutions, the slopes of the lines formed by the equations should be equal. In this case, a1/b1 = 4/k is equal to a2/b2 = k/1. Therefore, for exercise 83, there are infinitely many solutions for all values of "k".

Infinitely many solutions:

Equations: kx + y = 16, 3x - 4y = -64

For infinitely many solutions, the slopes of the lines formed by the equations should be equal. In this case, a1/b1 = k/1 is equal to a2/b2 = 3/-4 = -3/4. Therefore, for exercise 84, there are infinitely many solutions for all values of "k".

Thus, the required answers are:

Exercise 79: No solution for all values of "k".

Exercise 80: Exactly one solution for all values of "k".

Exercise 81: Infinitely many solutions for all values of "k".

Exercise 82: No solution for all values of "k".

The probability that a randomly selected bill will be at least $39.10 is 0.03216 percent.

According to the question, given that

The average daily dinner tab at a nearby restaurant has a normal distribution with a standard deviation of $6 and a mean of $28.

Let X = daily dinner bills in a local restaurant

So, X ~ N(μ = 28, σ^2 = \(6^{2}\) )

The following equations give the normal distribution's z-score probability distribution:

 Z = (X - μ) /σ  ~ N(0,1)

where,  μ = mean amount = $28

            σ  = standard deviation = $6

The Z-score calculates the deviation of the measure from the mean in standard deviations. We look at the z-score table after determining the Z-score to determine the p-value (area) connected to it. The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value.

As a result, = P(X $39.10) is the chance that a randomly chosen bill will be at least $39.10.

P(X ≥ $39.10) = P (X - μ) /σ  ≥ \(\frac{39.10 - 28}{6}\)) = P(Z ≥ 1.85) = 1 - P(Z < 1.85)

                                                               = 1 - 0.96784 = 0.03216

Now, the P(Z x) or P(Z x) is presented in the z table. By examining the value of x = 1.85 in the z table, which has an area of 0.96784, the probability stated above is derived.

Therefore, there is a 0.03216 percent chance that a randomly chosen bill will be at least $39.10.
