Answers

Answer 1

Phone class is a class that will be used to store the price, color, and screen resolution of phones. Below is the code snippet for the Phone class in Java.public class Phone {double price;String color;int screenResolution;public void setPrice(double price) {this.price = price;}public void setColor(String color)

{this.color = color;}public void setScreenResolution(int screenResolution) {if (screenResolution > 300) {this.screenResolution = 300;} else {this.screenResolution = screenResolution;}}public double getPrice() {return price;}public String getColor() {return color;}public int getScreenResolution() {return screenResolution;}}ExpensivePhone class extends the Phone class and adds two additional fields: screenResolution (maxScreenResolution = 450 ppi) and numLenses (multiple lenses = up to three).

Below is the code snippet for the ExpensivePhone class.public class ExpensivePhone extends Phone {int screenResolution;int numLenses;public void setScreenResolution(int screenResolution) {if (screenResolution > 450) {this.screenResolution = 450;} else {this.screenResolution = screenResolution;}}public void setNumLenses(int numLenses) {if (numLenses > 3) {this.numLenses = 3;} else {this.numLenses = numLenses;}}public int getScreenResolution() {return screenResolution;}public int getNumLenses() {return numLenses;}}So, in this way we can create the Phone and ExpensivePhone classes in Java.

Provide two distinct examples, each from a distinct application domain, where ethics, privacy and confidentiality pertain to spatial data other than tracking data. Discuss in detail how GIS approaches

Answers

Spatial data pertains to data that is generated and is relevant to a specific location, object or phenomenon. Ethical considerations, privacy and confidentiality are issues that are prevalent in the context of GIS approaches and spatial data analysis. The following are two distinct examples from a distinct application domain that highlights how ethics, privacy and confidentiality are important for spatial data other than tracking data:Example 1 - Environmental Impact Assessment: An Environmental Impact Assessment (EIA) is an evaluation of the environmental consequences that arise as a result of various activities such as construction, mining and oil drilling. The assessment typically involves extensive fieldwork and the collection of a significant amount of spatial data.

EIA report highlights the potential effects of these activities on the natural environment, including endangered species and natural resources. However, the report should not compromise the privacy of individuals and communities residing in the area. Ethical considerations, privacy, and confidentiality are significant for EIA as the report should not reveal sensitive information about the local community, such as their location, cultural beliefs, or other socio-economic details that could be used to identify them. The GIS approach for EIA typically involves spatial data analysis of multiple layers such as topography, hydrology, and vegetation. These layers are then overlaid on top of each other to determine areas that may be affected by the proposed activity.Example 2 - Healthcare: Health care providers use spatial data to study the geographic distribution of health problems and the efficacy of health services. A healthcare provider can use spatial data to understand the distribution of diseases such as cancer or heart disease and plan healthcare interventions accordingly. However, sensitive information related to patients such as their names, social security numbers, and medical records must be protected to maintain their privacy.

Ethical considerations, privacy, and confidentiality are significant in this domain as the data must be kept secure from unauthorized access or disclosure. GIS approach for healthcare typically involves mapping of diseases and healthcare facilities across a geographic area. By doing so, the healthcare provider can identify the regions that need additional resources, including doctors, hospitals, and specialized care. They can also identify the areas where the services are inadequate, and the provision of services can lead to better health outcomes. Overall, GIS approaches help healthcare providers to make informed decisions while also maintaining the confidentiality and privacy of their patients.

Assume that a computer system has 32-bit virtual addresses and 4KB pages. There is a pro- cess in which its program text fits in the lowest page (i.e. from 0x00000000 to 0x00000FFF) and its stack fits in the highest page. The global data of this process are located from Ox00800000 to Ox00800FFF. (a) If traditional (one-level) paging is used, how many entries are needed in the page table? Show your calculation in detail. (b) How many page table entries are needed for two-level paging, with 10 bits in each part? Draw a figure to explain your answer.

Answers

A computer system has 32-bit virtual addresses and 4KB pages, for two-level paging with 10 bits in each part, we need 1,048,576 page table entries.

a. If traditional (one-level) paging is used, we need to calculate the number of entries required in the page table.

Total number of pages = Total virtual address space / Page size

= [tex](2^{32})[/tex] / (4KB)

= [tex]2^{32[/tex] / [tex]2^{12[/tex]

= [tex]2^{(32-12)[/tex]

= [tex]2^{20[/tex]

= 1,048,576 pages

The number of entries required in the page table would be 1,048,576.

(b) The virtual address space can be divided into two levels: the first level (directory) and the second level (page table) if two-level paging is employed, with 10 bits in each portion.

Total page table entries = Number of first-level entries × Number of second-level entries

= ([tex]2^{10[/tex]) × ([tex]2^{10[/tex])

= [tex]2^{(10+10)[/tex]

= [tex]2^{20[/tex]

= 1,048,576 entries

Therefore, for two-level paging with 10 bits in each part, we need 1,048,576 page table entries.

Discuss The Relation Between Vulnerabilities, Impacts, Threats, And Risks. Give An Example.

Answers

Vulnerabilities, Impacts, Threats, and Risks are the four significant components of the risk assessment process. Let's discuss their relationship and provide an example of each term.What are Vulnerabilities?Vulnerabilities are weaknesses in a system that may be exploited by cybercriminals. Vulnerabilities in a system can include outdated software, weak passwords, or lack of employee education and training.What are Threats?A threat is an external event that could cause harm to an organization.

Natural disasters, hacking attempts, or even user errors are all examples of threats.What are Impacts?The impacts refer to the potential consequences of a threat materializing. An impact can range from a minor inconvenience to a severe financial loss, reputation damage, or legal action.What are Risks?Risk is the likelihood of a threat materializing and the extent of the impact if it does. Risk management involves identifying potential risks, evaluating the probability of each occurring, and developing a plan to mitigate or eliminate them.Example:Suppose an e-commerce platform has a vulnerability in its security system. Hackers can exploit the flaw in the system and gain access to sensitive customer data, such as credit card information.

A threat that can exploit the vulnerability is the potential hacking attempt that can result in the loss of sensitive customer data. The impact of the threat materializing could be that the customers lose trust in the platform and stop making purchases. The risk of the vulnerability and the potential threat materializing could result in significant financial loss, legal action, or reputation damage, making it essential to identify, assess, and address the vulnerability.

Creating Ransomware In this assignment, your task is to write a simple ransomware using Python script with the pycryptodome package. The assumptions on the ransomware are as follows: 1) An attacker has already broken into a victim’s Linux/Unix machine on which Python 3.5 or above and pycryptodome package are installed; 2) the attacker put its ransomware program, which is not necessary to be a single file, in the victim’s machine; 3) the victim has three to four text files and a python file in the directory where ransomware locates. Note that the text files have extension ".txt" and the python file has extension ".py". The ransomware should perform the following: 1) It generates a random alphabet table for symmetric encryption using substitution cipher. 2) It encrypts all .txt files to .enc files in the current directory using the key that the attacker generated in step 1). The files in the other folders or the files in the same folder but having different file extensions must not be impacted by the ransomware. 3) It comments out all the content of the existing .py files in the target folder (do not delete the content) and replicates itself to the .py files for the further propagation. 4) The key in step 1) is encrypted to key.bin using public key encryption. (RSA 2048 from Lab2) 5) It will finally display a message for asking ransom "Your text files are encrypted. To decrypt them, you need to pay me $10,000 and send key.bin in your folder to [me]." "[me]" should be your student email address.
Other requirements: - In step 1), the key used to encrypt files must not appear in the source code of the ransomware program and must not be stored in the plaintext format in the victim’s system. - Ignore numbers, special characters and spaces in the encryption process of substitution cipher. - All .txt files locating in the folder where ransomware program is located must be deleted after they are encrypted to the .enc files. - You must implement substitution encryption by yourself and use pycryptodome for public key encryption. - The infected .py file in step 3) shares the public key of your original ransomware.
Your next task is to write programs, key-recovery and file-recovery programs that recover (decrypt) all the encrypted files if the victim pays the ransom. 6) The key-recovery program decrypt the encrypted key (key.bin) and store the decrypted key in key.txt. 7) The file-recovery program must allow a user to decrypt the encrypted files created in step 2) using the key file created in 6). You do not need to recover the infected .py file in step 3).

A new ransomware program, called "LockBit" has recently been discovered. This malicious software encrypts personal files on a computer, then demands payment in the form of cryptocurrency in order to decrypt the files. It is important to note that there is currently no known way to decrypt the files without paying the ransom.

LockBit is capable of infiltrating a computer system via malicious emails, spam, or drive-by downloads. Once on a system, the ransomware will begin to search for files to encrypt. After the encryption process is complete, a ransom note will be displayed on the computer's screen with instructions on how to pay the ransom.

To avoid becoming a victim of LockBit, it is important to always ensure that your computer is up-to-date and protected with a reputable antivirus and anti-malware software. Additionally, never click on links or open attachments from emails from unknown or untrustworthy sources.

 for (int i = 0; i < 8; i++) {
   if (b[r][i] == 'R' && i != c) {
     return 0;
   }

   if (b[i][c] == 'R' && i != r) {
     return 0;
   }
 }
 return 1;
}
void print_result(char b[8][8], int r, int c) {
 if (is_safe(b, r, c)) {
   printf("safe");
 } else {
   printf("unsafe");
 }
}

```Here, is_safe is a function that takes the board, row index, and column index as input and returns 1 if no other rook is present in the same row or column as the rook at b[r][c]. Otherwise, it returns 0. The print_result function is used to print the result based on the output of the is_safe function.This code is designed to work with an 8x8 chessboard, as specified in the question.

List three types of concerns that are answered by a
wireframe/mockup.

Answers

Three types of concerns that are answered by a wireframe/mockup are Layout and Structure,Functionality and Interaction and Visual Style and Branding.

Wireframes and mockups are visual representations of a design concept or user interface. They serve as a blueprint or prototype of a website, application, or product before the actual development or implementation phase.

They address various concerns and provide valuable insights during the design process. Here are three types of concerns that wireframes/mockups can answer:

1. Layout and Structure: Wireframes help answer questions about the overall layout and structure of the interface. They provide a visual representation of the content placement, navigation elements, and hierarchy of information.

Designers can determine if the layout is intuitive, if key elements are prominently displayed, and if the overall flow of information is logical.

2. Functionality and Interaction: Wireframes/mockups can address concerns related to functionality and interaction. They allow designers to map out user interactions, such as button clicks, form submissions, and menu navigation.

By visualizing the interface, designers can identify any potential usability issues, determine if interactions are clear and intuitive, and ensure that the design meets the intended functional requirements.

3. Visual Style and Branding: Wireframes/mockups provide a glimpse into the visual style and branding of a design. They help answer questions about color schemes, typography choices, imagery, and overall aesthetic appeal.

Designers can assess whether the design aligns with the brand guidelines, conveys the desired tone and emotion, and appeals to the target audience.

By addressing these concerns, wireframes and mockups play a crucial role in the design process, enabling designers to gather feedback, iterate on the design, and ensure a successful end product.

Write 8051 program to repeatedly send the ASCII code of the numbers from 1 to 9 serially from the serial port TxD at baud rate 2400 bps. Assume crystal frequency of 11.0592 MHZ. b) What will the value of TH1 be if crystal frequency is 12MHz? 24 MHZ?

Answers

For both a crystal frequency of 12 MHz and 24 MHz, the value of TH1 will be 205 (decimal) or 0xCD (hexadecimal).

Here's an 8051 assembly program to repeatedly send the ASCII code of the numbers from 1 to 9 serially from the serial port TxD at a baud rate of 2400 bps. The program assumes a crystal frequency of 11.0592 MHz:

```

ORG 0x0000        ; Program start address

MOV PCON, #0x80   ; Configure SM0 and SM1 for serial mode 1

MOV SCON, #0x50   ; Configure serial port for 8-bit data, variable baud rate

MOV TMOD, #0x20   ; Configure timer1 in mode 2 for baud rate generation

MOV TH1, #0xFD    ; Set TH1 for 2400 bps at 11.0592 MHz

MOV TCON, #0x40   ; Start timer1

MAIN_LOOP:

   MOV R1, #1     ; Initialize counter R1 with 1

   MOV A, R1      ; Load counter value to accumulator

   ADD A, #48     ; Convert counter value to ASCII code

   ACALL SEND_BYTE  ; Send ASCII code over serial port

   INC R1         ; Increment counter

   CJNE R1, #10, MAIN_LOOP  ; Repeat until counter reaches 10

   SJMP MAIN_LOOP ; Repeat forever

SEND_BYTE:

   MOV SBUF, A    ; Move data to serial buffer

WAIT:

   JNB TI, WAIT   ; Wait for the transmit complete flag to be set

   CLR TI         ; Clear the transmit complete flag

   RET            ; Return

END              ; End of the program

```For the second part of your question, the value of TH1 is determined based on the crystal frequency. Here's the value of TH1 for different crystal frequencies:

1. For a crystal frequency of 12 MHz:

  - TH1 = (256 - (Crystal Frequency / (Baud Rate * 32)))

  Plugging in the values:

  - TH1 = (256 - (12000000 / (2400 * 32)))

  - TH1 = 205 (decimal) or 0xCD (hexadecimal)

2. For a crystal frequency of 24 MHz:

  - TH1 = (256 - (Crystal Frequency / (Baud Rate * 32)))

  Plugging in the values:

  - TH1 = (256 - (24000000 / (2400 * 32)))

O(log3n) = O(lg n) since it takes O(log3n) calls to reach the base case and base of log is a constant difference B.

Answers

The correct answer is D. The asymptotic analysis algorithmic run time of the algorithm is [tex]O(n^{2/3})[/tex] or  [tex]O(n^{2/3})[/tex], which can be simplified as  [tex]O(n^{2/3})[/tex]).

In the given algorithm, the recursive function "soRecursive" is called with an input value "n". If the value of "n" is less than 3, the function returns 1. Otherwise, it recursively calls itself with the input value of n/3 and returns n multiplied by the result of the recursive call.

The key factor in determining the asymptotic run time is the recursive call with n/3 as the input. This recursive call will be made approximately log3(n) times before reaching the base case, where log3(n) represents the number of times "n" needs to be divided by 3 until it becomes less than 3.

Since the recursive call is performed [tex]n^{(2/3)[/tex] times (approximately) and each call involves a constant-time operation (returning n), the overall asymptotic run time of the algorithm is  [tex]O(n^{2/3})[/tex]).

This asymptotic analysis algorithmic justifies the choice of option D as the correct answer.

1. describe the process of testing software developed with the ipo (input, process, output), top-down, bottom-up, and use-case-driven devel- opment orders. which development order results in the fewest resources required for testing? what types of errors are likely to be discovered earliest under each development order? which development order is best, as measured by the combination of required testing resources and ability to capture important errors early in the testing process?

Answers

Software Testing in Different Development Orders:

IPO (Input, Process, Output): In IPO development order, testing focuses on verifying the correctness of input, processing, and output of individual software components.

Testing starts with validating the input data, then verifying the expected processing, and finally confirming the correct output.

The primary focus is on functional testing, ensuring the software performs its intended operations correctly.

Errors related to data validation, calculations, and output formatting are likely to be discovered earliest.

Top-Down:

Top-Down development order involves testing the higher-level modules or components first, followed by the lower-level ones.

Testing starts with the main module and progressively incorporates sub-modules.

Early testing identifies interface and integration issues between modules.

Errors related to module interactions, data sharing, and communication between modules are likely to be discovered earliest.

Bottom-Up:

Bottom-Up development order involves testing the lower-level modules first, followed by the higher-level ones.

Testing starts with the individual modules and gradually integrates them into larger components or systems.

Early testing focuses on ensuring the functionality of individual modules.

Errors related to module implementation, internal logic, and individual module behavior are likely to be discovered earliest.

Use-Case-Driven:

Use-Case-Driven development order involves testing based on specific user scenarios or use cases.

Testing is driven by the expected behavior and interactions of the software from the user's perspective.

Early testing emphasizes the correctness and completeness of specific use cases.

Errors related to use case coverage, user interactions, and fulfillment of user requirements are likely to be discovered earliest.

The Development Order Requiring Fewest Resources for Testing:

The IPO development order typically requires fewer resources for testing as it focuses on individual components and their functional correctness.

The Development Order Balancing Testing Resources and Error Discovery:

The best development order, considering both testing resources and early error discovery, depends on the specific project and its requirements.

Use-Case-Driven development order, which focuses on user scenarios, is often considered effective in capturing important errors early, as it aligns with user expectations.

However, each development order has its strengths and weaknesses, and the best choice depends on the project's complexity, team expertise, and other factors.

(b) All strings of even length that start in $a$

Answers

(a) $(a a+a b+b a)^*$ For the regular expression $(a a+a b+b a)^*$, the NFA with the states $q_0$, $q_1$, $q_2$, $q_3$, and $q_4$ with the transition function $\delta$ given below:$$\delta(q_0,a)=\{q_1\}$$$$\delta(q_0,b)=\{q_2\}$$$$\delta(q_1,a)=\{q_3\}$$$$\delta(q_2,b)=\{q_3\}$$$$\delta(q_3,a)=\{q_4\}$$$$\delta(q_3,b)=\{q_4\}$$$$\delta(q_4,a)=\{q_1\}$$$$\delta(q_4,b)=\{q_2\}$$

Here, $q_0$ is the initial state, and $q_4$ is the final state. If a string contains only $a's$, the NFA proceeds from $q_0$ to $q_1$ on the first $a$ symbol, to $q_3$ on the second $a$ symbol, and then loops back to $q_1$ on the third $a$ symbol, so that the NFA can accept all strings that contain three or more $a's$. Similarly, if a string contains only $b's$, the NFA proceeds from $q_0$ to $q_2$ on the first $b$ symbol, to $q_3$ on the second $b$ symbol, and then loops back to $q_2$ on the third $b$ symbol, so that the NFA can accept all strings that contain three or more $b's$.

If a string contains a mix of $a's$ and $b's$, the NFA can either stay in $q_0$ (for empty strings), move to $q_1$ (for an $a$), or move to $q_2$ (for a $b$).Once the NFA reaches $q_1$ or $q_2$, the NFA can either move to $q_3$ (for an $a$ or $b$), or move back to $q_0$ (for an empty string).From $q_3$, the NFA moves to $q_4$ (for an $a$ or $b$), and then loops back to $q_1$ or $q_2$ (depending on whether the $a$ or $b$ input is received).Hence, the NFA recognizes $(a a+a b+b a)^*$.b) All strings of even length that start in $a$ For all strings of even length that start with $a$, the NFA with the states $q_0$, $q_1$, and $q_2$ with the transition function $\delta$ given below:$$\delta(q_0,a)=\{q_1\}$$$$\delta(q_1,b)=\{q_2\}$$$$\delta(q_2,a)=\{q_3\}$$$$\delta(q_3,b)=\{q_0\}$$ Here, $q_0$ is the initial state, and $q_0$ is also the final state (since all strings of even length that start with $a$ end in $b$).

Answers

A sample size of at least 556 days would be needed to bring the maximum half-width of all five confidence intervals down to under ±$1.15.

Effect of increased sample size from 30 days to 300 daysThe news vendor problem is a mathematical problem that is used to determine the order quantity of a product to maximize profit. In this question, we are asked to increase the sample size of the news vendor problem from 30 days to 300 and then compare the results of both sample sizes in terms of the profit/day confidence interval, profit/day standard deviation, and probability of loss at each q level.The effect of increasing the sample size from 30 days to 300 days is that it reduces the profit/day standard deviation and reduces the probability of loss at each q level. This is because increasing the sample size leads to a better estimation of the true mean and standard deviation of the demand distribution, which leads to more accurate predictions and less uncertainty in the estimates. The confidence interval also becomes narrower with a larger sample size as the sample size increases, the distribution of the sample mean becomes closer to the normal distribution, which means that the margin of error decreases.To determine the sample size (n) that would be needed to bring the maximum half-width of all five confidence intervals down to under ±$1.15, we can use the formula:n = (Za/2 * s / E)^2where Za/2 is the critical value of the standard normal distribution at the (1-a)/2 level of confidence, s is the standard deviation of the population, and E is the maximum half-width of the confidence interval.The maximum half-width of the confidence interval is ±$1.15, and the value of Za/2 can be calculated using a standard normal distribution table. Let's assume that the value of s is the same as the standard deviation of the sample mean of the 300-day sample size.Using these values, we can solve for n:n = (1.96 * 18.2 / 1.15)^2n = 555.9.

Concurrency control and locking is the mechanism used by DBMSs (Database Management Systems) for the sharing of data. Lock granularity specifies the level of lock and which resource is locked by a single lock attempt. Elaborate on the various levels that locking can occur.

Answers

In DBMSs (Database Management Systems), concurrency control and locking is the mechanism used for data sharing. Lock granularity specifies the level of lock and which resource is locked by a single lock attempt.

The various levels that locking can occur are as follows: Record level locking: A single record within a table is locked by a record-level lock. Table-level locking: The whole table is locked by a table-level lock. Page-level locking: A single data page (4-8 KB in size) is locked by a page-level lock. Index level locking: The whole index file is locked by an index-level lock. Field level locking: A single field or attribute is locked by a field-level lock.

It can be done at either table-level or record-level. In most cases, record-level locking is preferred because it allows for greater concurrency by enabling multiple users to access different records at the same time. Locking at higher levels, such as table-level locking or page-level locking, can cause bottlenecks, and it is usually reserved for situations when there is a high degree of contention for a particular resource. The type of locking mechanism that is chosen is determined by the requirements of the application and the level of contention for the resources.

The statement "Recursion is usually (not always) less efficient than iterative solutions" is true. Recursion is the concept of a function calling itself directly or indirectly.

The iterative solution, on the other hand, is a repetitive solution that executes a sequence of instructions over and over until a particular condition is fulfilled. When compared to iterative solutions, recursive solutions are often less effective.A recursive algorithm must first call itself to do so.

Each recursion of the algorithm demands that a new stack frame be created. The memory usage of recursive solutions is higher as a result of this. The recursive solution has a higher likelihood of exceeding the memory limit and crashing the program.

Answers

The structure that is limited to access elements only at structure end is Queue. Queue is a linear data structure that follows the FIFO (First In First Out) principle. In a queue, the insertion of elements takes place at the rear and deletion of elements takes place at the front.

Hence, the elements can only be accessed at the two ends and not in between. The given options are: a. Both List and Stack- Incorrect because lists allow for accessing elements in the middle and not just at the end. Stacks allow accessing elements from one end only, but that end could be either the top or the bottom, not just the end. Both Queue and List- Incorrect because Lists allow for accessing elements in the middle.

All of the other answers - Incorrect because only Queue limits access to elements only at the end. d. Both Stack and Queue - Incorrect because Stack can only access elements from one end, but that end could be either the top or the bottom, not just the end.  Thus, the correct answer is option D. Both Stack and Queue have an important feature of accessing the elements in the data structure from one end only. When the deletion of elements takes place, the elements can only be deleted from the end where they were added. This is called the principle of LIFO (Last In First Out) and is applicable in the case of Stack. In the case of the Queue, elements can be accessed at both ends. However, it follows the FIFO principle, which means that the elements that are inserted first will be removed first. Therefore, the elements in the Queue can be accessed only at the end where they were added.

And the rumor of this new presence having spread itself whisperingly around, there arose at length from the whole company a buzz, or murmur, expressive of disapprobation and surprisethen, finally, of terror, of horror, and of disgust.Based on the details in the excerpt, what is the primary purpose of this passage?to amuseto informto thrillto warn What is the solution to the trigonometric inequality sin^2(x) > cos(x) over the interval 0= x= 2pi radians? 9.

A letter to stockholders Raindrops falling in Boston may sometimes be contaminated owning to absorption of gaseous pollutants while falling through the air. The highest average daily SO concentration in the air over Boston is around 0.36 x 10 percent by volume. When this concentration exists uniformly throughout the air, what is the SO concentration in a 0.1 cm raindrop reaching the ground after falling for 5 minutes in the polluted air? The effect of the relative velocity between the drop and the air may be neglected; i.e., for diffusion purposes, it may be assumed that the drops are stationary in the air with Ds0-Air =0.2 cm/sec. Within the drop, Ds0,-M0 = 2 x 10 cm/sec. The temperature and pressure may be assumed uniform at 60F and 1 atm. Dilute solutions of SO in HO obey Henry's law, for example: pv = He where p, is the vapor pressure of SO in equilibrium with the solution in which the SO concentration is c, and H is constant. It is known that H= 180 cm'atm/g-mole for the above conditions. Find the area under the given curve over the indicated interval.y=x^2+x+5; [3,5] Discuss what a bailment is and how a bailment is formed? Is it ever possible for a bailment to be formed without any words? Why or why not?Think about this:John and Debbie live together as a couple for five years. John discovers that Debbie has been cheating. A fierce argument ensues. Debbie does not want this to escalate so she takes a few things and leaves. Three weeks later she returns to get the rest of her possessions. John tells her he burned everything. Debbie tells him she is going to sue based on breach of bailment. In a "cycle batch" processing, which of the following components is NOT directly required to compute the optimal/economical size of a batch order?

Each time the retailer places an order for x units, it is charged a flat fee of $25. Carrying costs are $34 per unit per year. How many times should the retailer reorder each year and what should be the lot size to minimize inventory costs? What is the minimum inventory cost? They should order units times a year. The minimum inventory cost is $ Determine the coordinates of the points on the graph of y= 3x12x 2at which the slope of the tangent is 0 . 16.
