Zack should use a line with one arrowhead to map an abandoned line of reasoning.

A line with one arrowhead is commonly used in diagrams to represent the direction of a process or flow of information. In the case of mapping an abandoned line of reasoning, the line can be used to show the original train of thought that was pursued but later abandoned.

The arrowhead can indicate the point at which the reasoning was abandoned or diverted. Therefore, using a line with one arrowhead would be the most appropriate shape for Zack to use. The other shapes listed (orange oval, green rectangle, red) do not provide a clear representation of a line of reasoning and would not be suitable for this purpose.

Answer:

4 meters

Step-by-step explanation:

Assuming that the garden is a rectangular garden, its area would be length ×width.

Let the length be L meters and the width be W meters.

Area= L ×W

48= LW -----(1)

Given that the length is 3 times the width,

L= 3W -----(2)

Substitute (2) into (1):

48= 3W(W)

3W²= 48

Divide both sides by 3:

W²= 48 ÷3

W²= 16

Square root both sides:

\(W = \sqrt{16} \)

W= 4 (reject negative as width cannot be a negative number)

Thus, the width of the garden is 4 meters.

Orion Flour Mills will initially report the $590 insurance amount as prepaid insurance and expense over the first year of coverage is $72120.

Given that,

Lapeer Flour Mills spent money on the following items in addition to buying new machinery: $64,00 in purchase price, plus sales tax 5,450 equipment shipments, 890 equipment insurance for the first year, and 590 equipment installations 1,780

We have to find the above expenditures for the new machines.

We know that,

Total cost of new machine = Purchase price + Sales tax+ Shipment of machine+ Installation of machine

= $64000+$5450+$890+$1780

= $72120

Therefore, Orion Flour Mills will initially report the $590 insurance amount as prepaid insurance and expense over the first year of coverage is $72120.

Answer:The mean for the data in the dot plot is 5. What is the

absolute deviation for the data point at 7?

2

Step-by-step explanation:

Answer:

\(z=\frac{931-1131}{\frac{333}{\sqrt{30}}}=-3.290\)  

Now we can calculate the p value using the alternative hypothesis:

\(p_v =P(z<-3.290)=0.0005\)  

Since the p value is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 1131

Step-by-step explanation:

Information given

\(\bar X=931\) represent the sample mean

\(\sigma=333\) represent the population standard deviation

\(n=30\) sample size  

\(\mu_o =1131\) represent the value to check

\(\alpha=0.05\) represent the significance level

z would represent the statistic

\(p_v\) represent the p value

System of hypothesis

We want to verify if the true mean is less than 1131, the system of hypothesis would be:  

Null hypothesis:\(\mu \geq 1131\)  

Alternative hypothesis:\(\mu <1131\)  

The statistic is given by:

\(z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}\) (1)  

Reaplacing we got:

\(z=\frac{931-1131}{\frac{333}{\sqrt{30}}}=-3.290\)  

Now we can calculate the p value using the alternative hypothesis:

\(p_v =P(z<-3.290)=0.0005\)  

Since the p value is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 1131

Dilation by a scale factor of 5 does not preserve congruence, hence the correct answer is option c.

1. Rotation transformation: A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise.

2. Reflection transformation: In a reflection transformation, all the points of an object are reflected or flipped on a line called the axis of reflection or line of reflection.

3. Translation transformation: Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system. In translation, only the position of the object changes, its size remains the same.

4. Dilation transformation: Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape. A dilation should either stretch or shrink the original shape.

Congruence is preserved by reflection, translation & rotation, as the image & pre-image have the same side lengths & angle measurements. But in case of dilation transformation, the side lengths change, hence this transformation does not preserve congruence.

Answer:

To find the shorter route, we need to calculate the distances for both routes and compare them.

Route through Towns P and Q:

The distance between Town A and Town P is 3 units to the right and 5 units up, so it is √(3² + 5²) = √34 km.

The distance between Town P and Town Q is 2 units to the right, so it is 2 km.

The distance between Town Q and Town B is 4 units to the right and 4 units down, so it is √(4² + 4²) = 4√2 km.

Therefore, the total distance for this route is √34 + 2 + 4√2 km.

Route through Town R:

The distance between Town A and Town R is 5 units to the right and 3 units up, so it is √(5² + 3²) = √34 km.

The distance between Town R and Town B is 5 units to the right and 7 units down, so it is √(5² + 7²) = √74 km.

Therefore, the total distance for this route is √34 + √74 km.

Comparing the distances, we can see that:

√34 + 2 + 4√2 km ≈ 10.2 km

√34 + √74 km ≈ 12.6 km

Therefore, the shorter route is the one that goes through Towns P and Q, which is approximately 10.2 km long.

a. Own Price Elasticity of Demand = (-30) / (0) = undefined. Since the own price elasticity of demand is undefined, we cannot determine if the demand is elastic, inelastic, or unitary elastic based on this information.

b. Cross-Price Elasticity of Demand = (12/7) / 0 = undefined. Since the cross-price elasticity of demand is undefined, we cannot determine if goods X and Y are substitutes or complements based on this information.

c. Income Elasticity of Demand = (-2860.71) / (0) = undefined. Since the income elasticity of demand is undefined, we cannot determine if good X is a normal or inferior good based on this information.

d. We cannot calculate the own advertising elasticity of demand with the provided data.

a. To determine the own price elasticity of demand, we need to use the formula:

Own Price Elasticity of Demand = (% Change in Quantity Demanded) / (% Change in Price)

Given the demand equation OX​d​ = 7−15PX​+2Py​+0.5M+A, we can calculate the derivative of demand with respect to price:

d(OX​d​) / d(PX​) = -15

Now, let's plug in the values:

% Change in Quantity Demanded = (d(OX​d​) / d(PX​)) * (PX​ / OX​d​) = (-15) * (15 / 7) = -30

% Change in Price = (ΔPX​ / PX​) = (15 - 15) / 15 = 0

b. To determine the cross-price elasticity of demand between goods X and Y, we use the formula:

Cross-Price Elasticity of Demand = (% Change in Quantity Demanded of Good X) / (% Change in Price of Good Y)

Using the same demand equation, we calculate the derivative of demand with respect to the price of good Y:

d(OX​d​) / d(Py​) = 2

Now, let's plug in the values:

% Change in Quantity Demanded of Good X = (d(OX​d​) / d(Py​)) * (Py​ / OX​d​) = (2) * (6 / 7) = 12/7

% Change in Price of Good Y = (ΔPy​ / Py​) = (6 - 6) / 6 = 0

c. To determine the income elasticity of demand, we use the formula:

Income Elasticity of Demand = (% Change in Quantity Demanded) / (% Change in Income)

Using the same demand equation, we calculate the derivative of demand with respect to income:

d(OX​d​) / d(M) = 0.5

Now, let's plug in the values:

% Change in Quantity Demanded = (d(OX​d​) / d(M)) * (M / OX​d​) = (0.5) * (-40000 / 7) = -2860.71

% Change in Income = (ΔM / M) = (-40000 - (-40000)) / (-40000) = 0

d. The own advertising elasticity of demand measures the responsiveness of quantity demanded to changes in advertising expenditure. Unfortunately, the given demand equation does not provide any information about advertising expenditure or its impact on quantity demanded.

Explanation:

The mean absolute deviation is the summary of absolute deviations from the central point or average of a data set. The central point measurement can be the mean, median or mode of the data set. An average absolute deviation can be used instead of a standard deviation to measure dispersion from central point.

In the above case, a sample is taken of 20 trees and there is a mean absolute deviation of 2, hence, median can be between 59 and 63. Also sample represents population, therefore mean of another sample taken is likely to be same as the previous one taken. Mean invariably gets more accurate as sample size increases too.

See below for the proof of the equation \(\frac{ax + by}{x + y} - \frac{ax - by}{x - y}= 2(a - b)\)

The equation is given as:

\(\frac{ax + by}{x + y} - \frac{ax - by}{x - y}= 2(a - b)\)

Take the LCM

\(\frac{(ax + by)(x - y) -(ax - by)(x + y)}{(x + y)(x - y)}= 2(a - b)\)

Expand

\(\frac{ax^2 - axy + bxy - by^2 -ax^2 - axy + bxy + by^2}{(x + y)(x - y)}= 2(a - b)\)

Evaluate the like terms

\(\frac{-2axy + 2bxy }{(x + y)(x - y)}= 2(a - b)\)

Rewrite as:

\(\frac{-2axy + 2bxy }{x^2 - y^2}= 2(a - b)\)

Factorize the numerator

\(\frac{2(a - b)(x^2 - y^2)}{x^2 - y^2}= 2(a - b)\)

Divide

2(a - b)= 2(a - b)

Both sides are equal

Hence, the equation \(\frac{ax + by}{x + y} - \frac{ax - by}{x - y}= 2(a - b)\) has been proved

Step-by-step explanation:

A person's cardiovascular fitness, age, weight, gender, and the severity of the activity performed may all play a role in how fast a person attains steady-state and fully recovers. When an individual is fit, they tend to have a lower resting heart rate than an unfit person. Furthermore, a fit person's heart rate is less likely to climb to high levels during activity, and their muscles are more efficient, requiring less oxygen to function. Finally, fit people tend to have better cardiovascular health and are more capable of removing waste products from their muscles, allowing for a quicker recovery time.

RQ stands for respiratory quotient and represents the ratio of carbon dioxide produced to oxygen consumed. During exercise, RQ rises because the body is using more carbohydrates than fats to generate energy, which increases carbon dioxide production. During the recovery period, RQ decreases as the body switches back to using fat as its primary energy source and oxygen consumption increases.The graph/plot of RQ as a function of time during rest, physical activity, and recovery phases should show a steady increase during physical activity and a decline during recovery. This variation makes sense because during exercise, the body's demand for energy increases, and RQ increases as a result. Conversely, during recovery, the body switches back to using fat as its primary energy source, resulting in a decrease in RQ.

3(x + 5)

The distributive property states that you are distributing whatever is outside the parenthesis to all terms within the parenthesis. For complex distributive questions, you will have to simplify the parenthesis first (if you can) before distributing.

In this case, the example given is 3(x + 5).

First, distribute 3 to all terms in the parenthesis by multiplication:

3(x + 5)

= (3 * x) + (3 * 5)

= 3x + 15

3x + 15 is your answer.

~

Another more complex distribute property can involve powers. Take for example:

(7x + 5)²

In this case, you will use the distributive method of FOIL, or (First, Outside, Inside, Last). Set the question:

(7x + 5)² = (7x + 5)(7x + 5)

First: 7x * 7x = 49x²

Outside: 7x * 5 = 35x

Inside: 5 * 7x = 35x

Last: 5 * 5 = 25

Next, combine like terms:

49x² + 35x + 35x + 25

49x² + (35x + 35x) + 25

49x² + (70x) + 25

49x² + 70x + 25 would be your answer.

The value of the unknown should be set at 5 so that 98 of 6- oz. mugs won't overflow is A)5.18.

Given data

A soft- drink machine can be regulated so that it discharges an normal of? oz. per mug. The ounces of filler are typically distributed with a standard divagation of0.4 oz.

What value should be set at so that 98 of 6- oz. mugs won't overflow?

Let μ be the mean ounces of filler per mug.

μ can be attained by using the formula

μ = 6 oz. = 6/8 = 0.75 mugs.

Now, given σ = 0.4 oz.

The Z- score for a 6- oz mug can be calculated as follows

z = ( x- μ)/ σ

Then, x = 6 oz = 6/8 = 0.75 mugs.

μ = 0.75 mugs

σ = 0.4 oz.

z = (0.75-0.75)/0.4 = 0

For 98 of 6- oz mugs to not overflow, we need to find the value of μ similar that P( z Since the Normal distribution is symmetric about the mean, we have

P( 0< z We can look up the value of

z_score for P( 0< z

standard normal distribution table or use the inverse function on a calculator similar as Excel.

Using a table, we get the value ofz_score = 2.33.

Now, z = ( x- μ)/ σ2.33 = (0.75- μ)/0.4

μ = 0.75-0.4 ×2.33

μ = 0.75-0.932

μ = -0.182 oz.6 oz in terms of ounces = 6 *0.125 = 0.75 oz.

oz per mug in terms of ounces = ? *0.125 oz.

Using the values from above

μ = -0.1820.75 = 0.568 oz. ≈0.57 oz.

= 0.57/0.125 = 4.56 or 5

Anna spends $20 less than her father on the 500 km trip.

Given: Anna's car uses 5 Liters per 100 km

Her father's car uses 7 Liters per 100 km

Cost of petrol is $2 per Liter

Anna spends less than her father on a 500 km trip. To find by how less Anna had spent than her father.

Let's solve the question:

According to the question Anna's car uses:

5 Liters per 100 km or

100 km is travelled with 5 Liters of petrol.

Then 1 km is travelled by 5 / 100 Liters of petrol.

1 km is travelled by 1 / 20 Liters of petrol by Anna.

According to the question Anna's father car uses:

7 Liters per 100 km or

100 km is travelled by 7 Liters of petrol.

Then 1 km is travelled by 7 / 100 Liters of petrol.

1 km is travelled by 7 / 100 Liters of petrol by Anna's father.

Now 500 km is travelled by:

        500 × 1 / 20 Liters of petrol = 25 Liters of petrol.

        Therefore 500 km is travelled by 25 Liters of petrol.

        500 × 7 / 100 Liters of petrol = 35 Liters of petrol

        Therefore, 500 km is travelled by 35 Liters of petrol.

Cost of petrol is $2 per Liter.

Anna: She consumes 25 Liters of petrol for the 500 km journey.

Her cost is 25 × 2 = 50

Anna's cost = $50

Anna's father: He consumes 35 Liters of petrol for the 500 km journey

His cost is 35 × 2 = 70

Anna's father cost = $70

Therefore, the difference in cost = (Anna's father cost - Anna's cost) = ($70 - $50) = $20.

Hence Anna spends $20 less than her father on the 500 km trip.
