The final value of the truck after depreciation and the number of years you own the truck are the two variables in this problem.  

The dependent variable is the final value of truck after depreciation and the independent variable is the number of years you own the truck.

We are given that the initial value of truck is $12,400 and depreciation value per year is $820.

We know that,

Final Value = Initial Value - Depreciation value per year * Number of years

Let Final value be y

Let the number of years be x.

Hence, the equation will be:-

y = 12400 - 820*x

y = 12400-820x

We can clearly see from the equation that the final value of truck will depend on the number of years you own the truck.

53.9 degree is the angle of the compass direction of a line connecting your starting point to your final position measured from north of west.

A compass is a tool for orientation and navigation that displays direction in relation to the four cardinal directions of the earth (or points). The directions north, south, east, and west are typically represented on the compass face as initialised abbreviations in a design called a compass rose. The rose can be aligned with the corresponding geographic directions when the compass is employed; for instance, the rose's "N" mark points northward. Compass roses are frequently joined with (or occasionally replaced by) marks indicating angles in degrees. East is 90° degrees, south is 180° degrees, and west is 270° degrees, with north being 0° and the angles increasing clockwise.

Here,

You started by travelling west to north.

Your entire distance from the beginning location is your hypotenuse.

\(H^{2}= P^{2}+ B^{2} \\\\H^{2}= 17.5^{2}+ 24^{2}\\\\H^{2}= 306.25+ 576\\\\H=\sqrt{882.25} \\\\=29.7 meters\)

You are moving in the northwest.

Use trigonometry now:

\(sin\alpha =\frac{B}{H}\\\\sin\alpha =\frac{24}{29.70} \\\\=0.808\\\\\alpha =53.9 degree\)

That's the angle of the compass direction.

The radius of the circle = r = 4 cm.The length of the segment = a = 3.2 cm.The length of the chord = s = 4.7 cm.We need to find the probability that a randomly selected point within the circle falls in the red shaded area.The red shaded area is a segment of the circle.

Let O be the centre of the circle. Join OA and OB.Let the chord AB cut the circle at C. Join OC. Now, ΔOCA and ΔOCB are congruent (RHS congruence) becauseOA = OB (radii of the same circle)AC = BC (length of the chord)OC = OC (common side)Therefore, ∠OCA = ∠OCB = θ (say)Also, ∠OAC = ∠OBC (vertically opposite angles)Now, ∠OCA + ∠OAC = 90° (angle sum property of the triangle) ⇒ θ + ∠OAC = 90°and ∠OCB + ∠OBC = 90° (angle sum property of the triangle) ⇒ θ + ∠OBC = 90°Adding the above two equations, we get,2θ + ∠OAC + ∠OBC = 180°2θ + ∠AOB = 180° (angles in a straight line)θ = (180° - ∠AOB) / 2

Therefore, θ = (180° - ∠AOB) / 2= (180° - 60°) / 2= 60° / 2= 30°Using the formula for the area of the segment of the circle, we have,Area of the segment = (1/2)rsinθArea of the segment = (1/2)×4×7.56×(sin30°)Area of the segment = 6.28 cm2Now, the area of the circle is πr2 = π×42 = 16π cm2.So, the probability that a randomly selected point within the circle falls in the red shaded area is given by the ratio of the area of the segment to the area of the circle.P(red shaded area) = Area of the segment/Area of the circleP(red shaded area) = 6.28/(16π)P(red shaded area) = 0.125 or 12.5%Therefore, the required probability is 12.5%.Hence, the answer is 12.5%.

To forecast sales for weeks 10-13 using trend projection with regression, you need to follow these steps:

1. Gather the data: Collect sales data for the past nine weeks.

2. Calculate the trend line: Use regression analysis to find the equation for the trend line. This equation represents the overall trend in sales over the past nine weeks.

3. Plug in the values: Substitute the values of weeks 10-13 into the equation to obtain the forecasted sales for each week.

To calculate the error measures (CFE, MSE, σ, MAD, and MAPE) and r², you need to compare the forecasted sales with the actual sales data for weeks 10-13. Here's how you calculate each measure:

- CFE (Cumulative Forecast Error): Sum up the differences between the forecasted and actual sales for each week.
- MSE (Mean Squared Error): Calculate the average of the squared differences between the forecasted and actual sales for each week.
- σ (Standard Deviation of Error): Take the square root of the MSE.
- MAD (Mean Absolute Deviation): Calculate the average of the absolute differences between the forecasted and actual sales for each week.
- MAPE (Mean Absolute Percentage Error): Calculate the average of the absolute percentage differences between the forecasted and actual sales for each week.
- r² (Coefficient of Determination): This measure indicates how well the trend line fits the actual data. It ranges from 0 to 1, where 1 represents a perfect fit.

To obtain the trend projection with regression forecast for weeks 10-13, you substitute the week numbers into the trend line equation and calculate the corresponding sales values.

To forecast sales for weeks 10-13 using trend projection with regression, you need to gather the data, calculate the trend line equation, and substitute the week numbers to obtain the forecasted sales.

The required equation of change is : C= $40 - 10x, where x is the highest price of gas and C is the change.

Let's start by finding the total cost of the 10 gallons of gas. Let's assume that the price of gas is x dollars per gallon at the gas station with the highest price. Then, the total cost of 10 gallons of gas is:

10x dollars

Since Steve paid with two $20 bills, the total amount he paid is:

$40

Therefore, the equation we need to solve to find Steve's change is:

$40 - 10x = C

where C is the amount of change that Steve will receive. We can simplify this equation by subtracting 10x from both sides:

$40 - 10x - 10x = C - 10x

$40 - 20x = C - 10x

Then, we can simplify further by adding 10x to both sides:

$40 - 20x + 10x = C

$40 - 10x = C

Now, we have an equation that relates the price of gas to the amount of change that Steve will receive. To solve for C, we need to know the price of gas at the gas station with the highest price. Once we know that value, we can substitute it into the equation and solve for C.

Answer:

3 times.

Step-by-step explanation:

She has 1 1/2 hour to spend in the gym.

1 hr = 60 minutes.
1/2 of an hour= 1/2 * 60= 30 minutes.

In total, she spends 90 minutes in the gym.

If 1/3 of an hour is meant in running, it translates into: 1/3 * 60 = 20 minutes.

If 1/6 of an hour is spent in weight-lifting, it translates into: 1/6 * 60 = 10 minutes.

In total, she spends, 20 minutes + 10 minutes = 30 minutes for both activities.

To obtain the number of times she would perform both activities, we divide the total amount of time spent in the gym by the amount of time spent for both activities.

 90 minutes/30 minutes= 3 times for each cycle.

To find the elasticity of demand at a price of $68, we need to use the formula: Elasticity of Demand = (% Change in Quantity Demanded / % Change in Price).

We can start by calculating the current quantity demanded at a price of $68, using the given demand function: d(68) = 100 * 68 = 6,800, Now, let's consider a small increase in price from $68 to $69. The percentage change in price is:
% Change in Price = ((69 - 68) / 68) * 100% = 1.47%
Using the demand function, we can calculate the new quantity demanded at the price of $69:
d(69) = 100 * 69 = 6,900

The percentage change in quantity demanded is: % Change in Quantity Demanded = ((6,900 - 6,800) / 6,800) * 100% = 1.47%, Now, we can plug in these values into the elasticity of demand formula: Elasticity of Demand = (1.47% / 1.47%) = 1
Therefore, the elasticity of demand at a price of $68 is equal to 1. This means that the demand for this product is unit elastic at this price point, indicating that a small change in price will result in an equal percentage change in quantity demanded.
