Your bank account consists of a checking and savings accounts. Assume your expenses and earnings can be described by a random walk with an equal probability to spend one dollar or to receive one dollar in your checking account at every time interval. You are charged $5 for any transaction from the checking account to the savings account and viceversa. Also, assume that the cost per unit of cash, per unit of time r of keeping cash on hand is equal to $0. 1 dollars for any dollar on hand per time period. Determine:



a. The optimal values of the two thresholds s and S, i. E. , the amount of cash in your checking account restored after each transaction, and the maximum amount of cash in your checking account, respectively.


b. The long run average cost associated to the optimal cash management strategy and to the strategy with the same s but with a maximum amount of cash equal to 2S.


c. Are there any common criticisms of this model?

Answers

Answer 1

a. To determine the optimal values of the two thresholds s and S, we can use the Miller-Orr cash management model. The objective is to minimize the total cost of cash management, which includes transaction costs and the opportunity cost of holding cash.

Let's assume that the transaction cost of $5 applies whenever the cash balance in the checking account goes below s or above S. The expected daily cash balance is zero since expenses and earnings are equally likely, and the standard deviation of the cash balance is σ = √(t/2), where t is the time interval.

The optimal value of s is given by:

s* = √(3rT/4C) - σ/2,

where T is the length of the cash management period, and C is the fixed cost per transaction. The optimal value of S is given by:

S* = 3s*,

which ensures that the probability of a cash balance exceeding S is less than 1/3.

Using r = 0.1, T = 1 day, and C = $5, we obtain:

s* = √(30.11/4*5) - √(1/2)/2 = $16.82

S* = 3*$16.82 = $50.47

Therefore, the optimal values of the two thresholds are s* = $16.82 and S* = $50.47.

b. The long run average cost associated with the optimal cash management strategy can be calculated as:

Total cost = (s*/2 + S*) * σ * √(2r/C) + C * E(N),

where E(N) is the expected number of transactions per day. Since expenses and earnings are equally likely, E(N) = (S* - s*)/2 = $16.83. Therefore, the total cost is:

Total cost = ($16.82/2 + $50.47) * √(1/2) * √(2*0.1/$5) + $5 * $16.83 = $1.38 per day.

Now let's consider the strategy with the same s but with a maximum amount of cash equal to 2S. The expected daily cash balance is still zero, but the standard deviation is now σ' = √(t/3). The optimal value of S' is given by:

S' = √(3rT/2C) - σ'/2 = $35.35.

The long run average cost associated with this strategy is:

Total cost' = (s/2 + S') * σ' * √(2r/C) + C * E(N'),

where E(N') is the expected number of transactions per day. Since the maximum amount of cash is now 2S, we have E(N') = (2S - s)/2 = $34.59. Therefore, the total cost is:

Total cost' = ($16.82/2 + $35.35) * √(1/3) * √(2*0.1/$5) + $5 * $34.59 = $1.30 per day.

Therefore, the strategy with the same s but with a maximum amount of cash equal to 2S is slightly more cost-effective in the long run.

c. One common criticism of this model is that it assumes a constant transaction cost, which may not be realistic in practice. In reality, transaction costs may vary depending on the size and frequency of transactions, and may also depend on the banking institution and the type of account. Another criticism is that it assumes a random walk model for expenses and earnings, which may not capture the

Given ⊙E with diameter AC, m∠CED=(3x)°, (m∠BEC=3x+2)°, and m∠AEB=(6x+7)°. Find x and mBD⌢

Answers

The following is the value of x and mBD: x = 83/6 and mBD⌢ = 83°.

Given circle E (⊙E) with diameter AC, we have the following information:

1. m∠CED = (3x)°
2. m∠BEC = (3x + 2)°
3. m∠AEB = (6x + 7)°

Since AC is the diameter of the circle, the inscribed angle ∠AEB is subtended by the diameter and thus forms a semicircle. In a semicircle, the inscribed angle is always a right angle. Therefore, m∠AEB = 90°. We can now set up the equation:

(6x + 7)° = 90°

Solving for x:
6x = 83
x = 83/6

Now, we need to find the measure of arc BD (mBD⌢). We can do this by finding the measure of angle BEC, as the measure of an inscribed angle is half the measure of its intercepted arc.

m∠BEC = (3x + 2)° = (3(83/6) + 2)° = (83/2)°

Since the measure of an inscribed angle is half the measure of its intercepted arc:

mBD⌢ = 2(m∠BEC) = 2(83/2)° = 83°

So, x = 83/6 and mBD⌢ = 83°.

Answers

We can read 91 books in a year if you increase your reading speed so that each page takes you 30 seconds less than it did before.

How is the number of books calculated?

Now If each page now takes 30 seconds less to read than before,

then you will save 30*200 = 6000 seconds (or 100 minutes) on each book.

So, the time it will take you to read a 200-page book will be

20 minutes - 100 minutes = -80 minutes,

which means you will finish a 200-page book in 80 minutes (or 1 hour and 20 minutes).

In a year, there are 365 days. If you read for 20 minutes per day, then you will read for a total of

365 * 20 = 7300 minutes (or 121.67 hours) in a year.

Since you can finish a 200-page book in 80 minutes, you can read 7300/80 = 91.25 books in a year.

A person uses a screwdriver to turn a screw and insert it into a piece of wood. The person applies a force of 20 newtons to the screwdriver and turns the handle of the screwdriver a total distance of 0. 5 meter. How would these numbers be different with a hammer and a nail instead of a screwdriver and a screw

Answers

Using a hammer and nail instead of a screwdriver and screw would change the type of force applied (linear versus rotational) and the distance covered (shorter linear distance versus longer turning distance). These differences can affect the efficiency, holding power, and ease of use when connecting materials.

When using a screwdriver and screw, the applied force of 20 newtons and turning distance of 0.5 meters involve rotational motion to insert the screw into the wood. The screwdriver acts as a lever, and the screw's threads translate the rotational force into linear motion, increasing the grip strength and holding power.

In contrast, when using a hammer and nail, the force applied would be different because the action is linear instead of rotational. The hammer delivers a series of high-impact, short-duration forces to drive the nail into the wood. The amount of force required would depend on factors like the size of the nail, the hardness of the wood, and the user's strength.

Additionally, the distance covered during hammering would be different. Unlike the screwdriver's 0.5-meter turning distance, the hammer's motion covers a shorter linear distance as it strikes the nail head repeatedly. The total distance depends on the number of hammer strikes and the length of the nail.

To find the maximum concentration of an antibiotic between hours 1 and 7, first find the critical points of the function C(t), then evaluate C(t) at the critical points and endpoints to choose the highest value.

To determine the maximum concentration of the antibiotic between hours 1 and 7, follow these steps:
1. Find the critical points of the function C(t) = 4te^(-397). To do this, find the first derivative of the function, C'(t), and set it equal to 0.
2. Check the value of C(t) at the critical points and the endpoints of the interval, t=1 and t=7.
3. Choose the highest value of C(t) among the critical points and the endpoints.
1: Find the first derivative, C'(t).
C(t) = 4te^(-397)
C'(t) = 4e^(-397)(1-397t)
2: Set the first derivative equal to 0 and solve for t.
4e^(-397)(1-397t) = 0
1 - 397t = 0
t = 1/397
3: Evaluate C(t) at the critical point t = 1/397 and the interval endpoints t = 1 and t = 7.
C(1/397) = 4(1/397)e^(-397(1/397)) ≈ 0.01 ag/mg
C(1) = 4(1)e^(-397(1)) ≈ 0.00 ag/mg

The rule is x→y=−2x. Can you mark all the points that fit the rule on a coordinate plane?

Answers

Yes, the points that fit the rule x→y=−2x can be plotted or marked on a coordinate plane, and will form a straight line passing through the origin with a slope of -2.

The rule x→y=−2x means that for every value of x, the corresponding value of y is equal to -2 times x. To plot the points that fit this rule, we can choose some values of x, substitute them into the equation, and then plot the resulting points on the coordinate plane.

For example, if we choose x=1, then y=−2x=−2(1)=−2. So the point that fits the rule is (1, −2). Similarly, if we choose x=2, then y=−2x=−2(2)=−4. So the point that fits the rule is (2, −4).

We can continue this process for other values of x, and plot all the resulting points on the coordinate plane. The resulting graph will be a straight line that passes through the origin, with a slope of -2. This means that all the points that fit the rule will lie on this line.

A ferry is used to transport guests from the dock to two hotels across a large lake. The hotels are located 550 m apart. The first hotel is at a 49 angle between the dock and the second hotel. The second hotel is at a 56 angle between the dock and the first hotel. How far is each hotel from the dock?

Answers

The first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

To solve this problem, we can use trigonometry and create a system of equations based on the given angles and distances. Let's assume the distance between the dock and the first hotel is x meters and the distance between the dock and the second hotel is y meters.

Using the law of sines, we can relate the angles and distances:

For the first hotel:

sin(49°) = y / x     ...(Equation 1)

For the second hotel:

sin(56°) = x / y     ...(Equation 2)

We can rearrange Equation 1 to solve for y:

y = x * sin(49°)

Substituting this value of y into Equation 2:

sin(56°) = x / (x * sin(49°))

sin(56°) = 1 / sin(49°)

Now, we can solve for x by isolating it:

x = sin(56°) * sin(49°)

Plugging in the values and evaluating the equation:

x = 0.8290 * 0.7539

x ≈ 0.6246

Therefore, the distance between the dock and the first hotel (x) is approximately 0.6246 meters.

To find the distance between the dock and the second hotel (y), we can substitute this value back into Equation 1:

y = 0.6246 * sin(49°)

y ≈ 0.4931

Hence, the distance between the dock and the second hotel (y) is approximately 0.4931 meters.

In summary, the first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

where a is the hypotenuse (longest side) of a right-angled triangle, and b and c are the legs of the triangle.

1. x is the hypotenuse:

From the diagram below, we can see that, if x is the hypotenuse of the triangle, then 3 and four are the legs of the triangle. Therefore, using the above equation:

[tex]x^2 = 3^2 + 4^2[/tex]

⇒ [tex]x = \sqrt{3^2 + 4^2}[/tex]      [Taking the square root of both sides of the equation]

⇒ [tex]x = \sqrt{25}[/tex]

⇒ [tex]x = \bf 5[/tex]

2. x is one of the legs:

From the diagram below, we can see that when x is one of the legs, the hypotenuse is 4, and the other leg is 3.

The hypotenuse isn't 3 because the hypotenuse is the longest side in a right-angled triangle, and 4 is longer than 3.

Therefore,

[tex]4^2 = x^2 + 3^2[/tex]

⇒ [tex]x^2 = 4^2 - 3^2[/tex]             [Subtracting 3² from both sides]

⇒ [tex]x = \sqrt{4^2 - 3^2}[/tex]          [Taking the square root of both sides of the equation]

How would the variation that exists between the distance that a man walks in one hour and the rate at which the man is walking be described? f inversely g directly h both inversely and directly j irregular​

Answers

The relationship between these two variables can be described as inversely proportional.

The variation between the distance that a man walks in one hour and the rate at which the man is walking can be described as inversely proportional.

This means that as the rate at which the man is walking increases, the distance that he walks in one hour decreases. Similarly, as the rate at which he is walking decreases, the distance that he walks in one hour increases.

Therefore, the relationship between these two variables can be described as inversely proportional.

The results of the chi-square test of independence found that fear of crime depended on one's perception of whether their neighborhood was a high crime area or not. if the null hypothesis is rejected, which is the most appropriate conclusion that can be made

Answers

The most appropriate conclusion that can be made when the null hypothesis is rejected for the chi-square test of independence is: There is a significant association between fear of crime and one's perception of their neighborhood as a high crime area or not.

If the null hypothesis is rejected in a chi-square test of independence, it means that there is a significant association between the two variables being studied. In this case, the fear of crime is dependent on one's perception of whether their neighborhood is a high crime area or not.

Therefore, the most appropriate conclusion that can be made is that there is a significant relationship between the two variables, and one's perception of their neighborhood being a high crime area or not is a predictor of fear of crime. However, the chi-square test of independence does not determine causality, so it is not possible to conclude which variable is causing the other. Further research would be required to determine the direction and nature of the relationship between the two variables.

A gift bag is shaped like a rectangular prism and has a volume of 1152 cubic inches.

Answers

The volume of the gift bag is given as 1152 cubic inches.

Since it is shaped like a rectangular prism, we can write the formula for its volume as V = l × w × h, where l, w, and h are the length, width, and height of the rectangular prism, respectively.

To determine the dimensions of the gift bag, we need more information such as the ratio of its length, width, and height or any one of its dimensions. If we assume one of the dimensions, say, the length is L inches, then we can write the volume as V = L × w × h. Solving for w × h, we get w × h = V/L = 1152/L.

We can then use this equation along with the fact that the gift bag is a rectangular prism to find the other dimensions. For example, if the width is W inches, then we have h = 1152/(L × W) and the volume can be expressed as V = L × W × 1152/(L × W) = 1152.

Similarly, if the height is H inches, then we have w = 1152/(L × H) and the volume can be expressed as V = L × 1152/(L × H) × H = 1152.

The function f(x) = 2x^3 +30x^2 – 54x +5 has one local minimum and one local maximum. This function has a local minimum at x = with value
and a local maximum at x =
with value

Answers

The local maximum is at x = -9 with a value of 2575, and the local minimum is at x = 1 with a value of -17.

To find the local minimum and maximum of the given function, we need to find its critical points, where the derivative is zero or undefined.

[tex]f(x) = 2x^3 + 30x^2 - 54x + 5[/tex]

[tex]f'(x) = 6x^2 + 60x - 54[/tex]

Setting f'(x) = 0, we get:

[tex]6x^2 + 60x - 54 = 0[/tex]

[tex]x^2 + 10x - 9 = 0[/tex]

(x + 9)(x - 1) = 0

x = -9 or x = 1

Now, we need to determine if these critical points correspond to local minimum or maximum.

To do so, we can use the second derivative test. We calculate the second derivative of f(x):

f''(x) = 12x + 60

At x = -9:

f''(-9) = 12(-9) + 60 = -48 < 0

This means that f(x) has a local maximum at x = -9.

At x = 1:

f''(1) = 12(1) + 60 = 72 > 0

This means that f(x) has a local minimum at x = 1.

To find the values of the local minimum and maximum, we plug in the corresponding x-values into the original function:

[tex]f(-9) = 2(-9)^3 + 30(-9)^2 - 54(-9) + 5 = 2575[/tex]

[tex]f(1) = 2(1)^3 + 30(1)^2 - 54(1) + 5 = -17[/tex]

Therefore, the local maximum is at x = -9 with a value of 2575, and the local minimum is at x = 1 with a value of -17.

Use this information for Ms. Yamagata is going to tile the floor of her rectangular bathroom that is 9 feet long and 73 feet wide. The cost per 6-inch tile is $0. 50. The cost per 18-inch tile is $2. 75. 4. If Ms. Yamagata uses 6-inch tiles, what are the least number of tiles that she needs to buy to cover the floor? оâ

Answers

Ms. Yamagata needs to buy at least 2628 6-inch tiles to cover the floor of her rectangular bathroom.

To determine the least number of 6-inch tiles Ms. Yamagata needs to buy to cover her 9 feet long and 73 feet wide bathroom floor, follow these steps:

1. Convert the dimensions of the bathroom to inches, as the tiles are measured in inches:
  9 feet * 12 inches/foot = 108 inches long
  73 feet * 12 inches/foot = 876 inches wide

2. Determine the total area of the bathroom in square inches:
  Area = length * width = 108 inches * 876 inches = 94,608 square inches

3. Calculate the area of a single 6-inch tile:
  Area = length * width = 6 inches * 6 inches = 36 square inches

4. Divide the total area of the bathroom by the area of a single tile to find the least number of tiles needed:
  Number of tiles = total area / tile area = 94,608 square inches / 36 square inches ≈ 2,628.56

Since Ms. Yamagata cannot buy a fraction of a tile, she needs to buy at least 2,629 6-inch tiles to cover her bathroom floor.

Answer this following question
y = sin x + cos x / csc x

Answers

The expression equation y = sin x + cos x / csc x can be simplified to y = cos x sin^2 x + cos^2 x.

To simplify the expression, we can first replace csc x with 1/sin x. This gives us y = sin x cos x + cos^2 x / sin x.

Next, we can factor out cos x from the numerator of the second term to get y = cos x (sin x + cos x) / sin x.

Using the identity sin^2 x + cos^2 x = 1, we can replace sin^2 x with 1 - cos^2 x in the numerator of the first term. This gives us y = cos x (1 - cos^2 x) / sin x + cos x (sin x + cos x) / sin x.

Simplifying the expression further, we get y = cos x (1 - cos^2 x + sin x + cos x) / sin x.

Finally, we can combine the terms in the numerator to get y = cos x (sin^2 x + 2cos x sin x + 1) / sin x.

Using the identity sin^2 x = 1 - cos^2 x, we get y = cos x (3cos^2 x + 2cos x) / sin x.

Simplifying the expression, we arrive at y = cos x (cos x + 2) (3cos x + 2) / sin x.

Therefore, the simplified expression is y = cos x sin^2 x + cos^2 x, which can also be written as y = cos x (sin x)^2 + cos^2 x.

Box of candy contains 0. 6 of a pound of caramels 3. 6 pounds of coconut What percent the contents of the box, by weight consists of caramels?

Answers

The contents of the box, by weight, consists of 14.29 percent caramels.

We need to find the percentage of caramels in the box, given the weights of caramels and coconut candies.

Step 1: Determine the total weight of the candies in the box.
The box contains 0.6 pounds of caramels and 3.6 pounds of coconut candies. Add these two weights together:

Total weight = 0.6 (caramels) + 3.6 (coconut)
Total weight = 4.2 pounds

Step 2: Calculate the percentage of caramels in the box.
To find the percentage, divide the weight of caramels by the total weight of the box and then multiply by 100:

Percentage of caramels = (Weight of caramels / Total weight) x 100
Percentage of caramels = (0.6 / 4.2) x 100

Step 3: Solve the equation.
Percentage of caramels = (0.6 / 4.2) x 100 ≈ 14.29%

So, approximately 14.29% of the contents of the box, by weight, consists of caramels.
