In order to maintain the same service level after the transition, the OEM would need to hold (or pool) a total of 80 units (transformers) in the FedEx warehouse.Here's the explanation:Given,Current on-time delivery performance = 95%Desired on-time delivery.
performance = 98%Total monthly demand = 400 transformersIn order to calculate the number of transformers needed, we can use the safety stock formula, which is:Safety stock = Z x √(σ²d + σ²lead time)Where,Z = Z-value for a given service levelσ²d = Variance of demandσ²lead time = Variance of lead timeUsing the given data, we get:Z = 2.05 (for a service level of 98%)σ²d = (0.05 x 400)² = 100σ²lead time = (0.25 x 4)² = 1Now,Substituting the values in the formula.
we get:Safety stock = 2.05 x √(100 + 1) = 22.67≈ 23 transformersTherefore, the OEM would need to pool 23 transformers in the FedEx warehouse, which means a total of 23 x 4 = 92 transformers annually.Now, the OEM would need to hold a total of 80 transformers in the FedEx warehouse in order to maintain the same service level as before the transition. This is calculated as follows:Average demand during lead time = (0.25 x 400) = 100 transformersTherefore, the number of transformers required to maintain the same service level would be:Total units required = Safety stock + Average demand during lead time= 23 + 100 = 123 transformers annuallyHowever, due to the new strategy, the lead time would be reduced by 50%, which means the OEM would need to hold half of the safety stock. So,Total units required = (23/2) + 100 = 80 transformers annuallyHence, the OEM would need to hold (or pool) a total of 80 units (transformers) in the FedEx warehouse.

The Journal of E-commerce Research Knowledge is a prestigious information systems research journal. It uses a peer-review process to select manuscripts for publication. Only about 10 percent of the manuscripts submitted to the journal are accepted for publication. A new issue of the journal is published each quarter.
• Unsolicited manuscripts are submitted by authors. When a manuscript is received, the editor assigns it a number and records some basic information about it in the system, including the title of the manuscript, the date it was received, and a manuscript status of "received." Information about the author(s) is also recorded, including each author's name, mailing address, e-mail address, and affiliation (the author's school or company). Every manuscript must have an author. Only authors who have submitted manuscripts are kept in the system. It is typical for a manuscript to have several authors. A single author may have submitted many different manuscripts to the journal. Additionally, when a manuscript has multiple authors, it is important to record the order in which the authors are listed in the manuscript credits. • At her earliest convenience, the editor will briefly review the topic of the manuscript to ensure that its con tents fall within the scope of the journal. If the content is not appropriate for the journal, the manuscript's status is changed to "rejected" and the author is notified via e-mail. If the content is within the scope of the journal, then the editor selects three or more reviewers to review the manuscript. Reviewers work for other companies or universities and read manuscripts to ensure their scientific validity. For each reviewer, the sys tem records a reviewer number, name, e-mail address, affiliation, and areas of interest. Areas of interest are predefined areas of expertise that the reviewer has specified. An area of interest is identified by an IS code and includes a description (for example, IS2003 is the code for "data base modeling"). A reviewer can have many areas of interest, and an area of interest can be associated with many reviewers. All reviewers must specify at least one area of interest. It is unusual, but possible, to have an area of interest for which the journal has no reviewers. The editor will change the status of the manuscript to "under review" and record which reviewers received the manuscript and the date it was sent to each reviewer. A reviewer will typically receive several manuscripts to review each year, although new reviewers may not have received any manuscripts yet. • The reviewers will read the manuscript at their earliest convenience and provide feedback to the editor. The feedback from each reviewer includes rating the manuscript on a 10-point scale f or appropriateness, clarity, methodology, and contribution to the field, as well as a recommendation for publication (accept or reject). The editor will record all of this information in the system for each review received, along with the date the feedback was received. Once all of the reviewers have provided their evaluations, the editor will decide whether to publish the manuscript and change its status to "accepted" or "rejected.'' If the manuscript will be published, the date of acceptance is recorded. • Once a manuscript has been accepted for publication, it must be scheduled. For each issue of the journal, the publication period (fall, winter, spring, or summer), publication year, volume, and number are recorded. An issue will contain many manuscripts, although the issue may be created in the system before it is known which manuscripts will be published in that issue. An accepted manuscript appears in only one issue of the journal. Each manuscript goes through a typesetting process that formats the content, including fonts, font size, line spacing, justification, and so on. Once the manuscript has been typeset, its number of pages is recorded in the system. The editor will then decide which issue each accepted manuscript will appear in and the order of manuscripts within each issue. The order and the beginning page number for each manuscript must be stored in the system. Once the manuscript has been scheduled for an issue, the status of the manuscript is changed to "scheduled." Once an issue is published, the print date for the issue is recorded, and the status of each manuscript in that issue is changed to "published."

for most business transactional databases, we should normalize relations into ____. group of answer choices 1nf 2nf 3nf 4nf
For most business transactional databases, we should normalize relations into 3NF (third normal form). Normalization is the process of organizing data in a database in a way that reduces redundancy and dependency. It helps in eliminating the anomalies and inconsistencies that may arise due to data duplication.
There are different normal forms (1NF, 2NF, 3NF, BCNF, 4NF, 5NF) that a database can be normalized into, depending on the degree of normalization required and the specific needs of the database. However, for most business transactional databases, 3NF is considered to be the most suitable level of normalization. In the third normal form, a table is in 2NF and every non-key attribute of the table is dependent on the primary key. In other words, every non-key attribute should depend only on the primary key and not on any other non-key attributes. This eliminates transitive dependencies and ensures that data is stored in the most efficient way possible.
To summarize, for most business transactional databases, normalizing relations into 3NF is crucial for maintaining data integrity, improving performance, and avoiding anomalies that may arise due to data duplication and inconsistency. Normalizing relations into 3NF is the best practice for most business transactional databases as it helps in organizing data in a way that eliminates redundancy and dependency. It ensures that data is stored in the most efficient way possible, improving performance and reducing the likelihood of inconsistencies that may arise due to data duplication. 3NF also helps in maintaining data integrity by eliminating transitive dependencies and ensuring that every non-key attribute depends only on the primary key.

it is not feasible on any system to store the entire os in firmware group of answer choices true false
The statement that it is not feasible on any system to store the entire operating system (OS) in firmware is true.
Firmware refers to the software that is embedded in a hardware device, typically in read-only memory (ROM) or flash memory. It contains the low-level instructions necessary for the device to function properly. While firmware can include a small portion of the operating system, it is not practical or feasible to store the entire OS in firmware.
Operating systems are complex software that consist of numerous components, including the kernel, device drivers, libraries, and various system utilities. These components require a significant amount of storage space, which is typically provided by secondary storage devices like hard drives or solid-state drives. Storing the entire OS in firmware would require a substantial amount of firmware memory, which is limited in most hardware devices.
Furthermore, firmware memory is primarily designed to store essential instructions and configurations for device initialization and basic functionality. It is not intended to accommodate the extensive codebase and data associated with a full-fledged operating system.
In conclusion, due to the size and complexity of operating systems, it is not feasible or practical to store the entire OS in firmware. Firmware memory is limited and primarily reserved for critical system instructions, while the OS is typically stored in secondary storage devices for efficient management and accessibility.

what is the big o of the following code i=0 loop (i
The given code has a loop that starts with an initial value of i=0 and continues until i reaches n. This means that the loop runs n times, where n is the input size. Therefore, the time complexity of the code can be expressed as a function of n, which is O(n).
This is because the running time of the code grows linearly with the size of the input. As the input size increases, the number of iterations in the loop also increases linearly, leading to a linear increase in the overall running time. In summary, the big O of the given code is O(n) because its time complexity grows linearly with the size of the input. The big O notation is used to express the upper bound of the worst-case scenario for the time complexity of an algorithm. It describes the rate of growth of the algorithm's running time with respect to the size of the input.
In this case, the code has a single loop that runs n times, making the time complexity of the code proportional to the size of the input. Therefore, we can say that the time complexity of the code is O(n). It's important to note that the big O notation only provides an upper bound on the time complexity of an algorithm. It does not describe the exact running time of the algorithm for a particular input size. The actual running time of the algorithm may be lower than the upper bound provided by the big O notation.

what distinguishes dynamic programming from divide and conquer
Divide and conquer and dynamic programming are the two important techniques used to solve problems in programming. The difference between the two is that divide and conquer solves the problem by dividing it into subproblems while dynamic programming solves the problem by dividing it into overlapping subproblems.
Divide and conquer:
It is a top-down strategy for solving problems by dividing it into subproblems and then solving each subproblem independently. The output of all the subproblems is then combined to produce the final solution to the problem. Examples of problems solved by the divide and conquer technique are the binary search algorithm, quicksort, and merge sort algorithm.Dynamic programming:
On the other hand, Dynamic programming solves problems by breaking them into overlapping subproblems and solving each subproblem once. Instead of solving each subproblem independently like divide and conquer, dynamic programming builds the solution to the problem in a bottom-up approach. An example of a problem that is solved using dynamic programming is the Fibonacci sequence.Both techniques aim to solve complex problems by breaking them down into smaller, more manageable problems, but the approach they take differs.

An Introduction to Programming with C++ by Diane Zak
Exercise 26:
If necessary, create a new project named Advanced26 Project and save it in the Cpp8\Chap11 folder. Also create a new source file named Advanced26.cpp. Declare
a 12-element int array named days. Assign the number of days in each month to
the array, using 28 for February. Code the program so that it displays the number of
days corresponding to the month number entered by the user. For example, when the user enters the number 7, the program should display the number 31. However, if the user enters the number 2, the program should ask the user for the year. The rules for determining whether a year is a leap year are shown in Figure 11-51. If the year is a leap year, the program will need to add 1 to the number of days before displaying the number of days on the screen. The program should also display an appropriate message when the user enters an invalid month number. Use a sentinel value to end the program. Save and then run the program. Test the program using the number 1, and then test it using the numbers 3 through 12. Test it using the number 2 and the year 2015. Then, test it using the number 2 and the year 2016. Also test it using an invalid number, such as 20.
Advanced26.cpp program which displays the number of days corresponding to the month number entered by the user along with the explanation of the code is given below:#include using namespace std;int main() { int month, year, days[12] = { 31,28,31,30,31,30,31,31,30,31,30,31 };
cout << "Enter the month number : "; cin >> month; if (month < 1 || month > 12) { cout << "Invalid month number!"; return 0; } if (month == 2) { cout << "Enter the year : "; cin >> year; if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) days[month - 1] = 29; } cout << "Number of days in " << month << " month is " << days[month - 1] << endl; return 0;}Firstly, the program prompts the user to enter the month number. Then, the program checks whether the entered number is between 1 and 12 or not. If it is not between 1 and 12, it displays an error message "Invalid month number!" and the program terminates. If the entered number is between 1 and 12, the program checks if it is equal to 2.

to resolve a domain name on the internet, the dns resolver first contacts:
To resolve a domain name on the internet, the DNS resolver first contacts a DNS root server.
What is DNS?
DNS stands for Domain Name System, which is a decentralized naming system for computers, services, or any resource linked to the internet or a private network. It translates domain names that humans can comprehend into numerical identifiers that machines can recognize.
It is a decentralized hierarchical naming system that translates human-readable domain names (e.g., www.example.com) into the numerical IP addresses (e.g., 192.0.2.1) used by computers to identify and communicate with each other on the Internet. DNS acts as a directory that maps domain names to their corresponding IP addresses, allowing users to access websites and other resources using familiar domain names instead of needing to remember complex IP addresses. It functions through a network of DNS servers that work together to resolve domain name queries, starting from the root DNS servers and moving down to authoritative DNS servers for specific domains. DNS also supports additional functionalities like mapping domain names to email servers and providing other related information like mail exchange (MX) records and text (TXT) records.
DNS Root Servers: A DNS root server is a server that stores the IP addresses of other DNS servers. The DNS root server's purpose is to answer the queries of DNS resolvers that don't know where to send their questions next to find the right IP address. It responds to DNS queries with the IP address of the top-level domain's DNS server, which is responsible for the requested domain name. The root servers are the topmost layer of the DNS hierarchy and the starting point of all domain name resolution on the internet. There are 13 root servers worldwide, and they are identified by the letters A to M.
