Final answer:
The SDLC steps are matched as problem/opportunity identification as first, analysis as second, design as third, development as fourth, and testing and installation as fifth. The design process is iterative, often involving prototyping, testing, and refinement.
Explanation:
The steps of the Software Development Life Cycle (SDLC) can be matched to their positions in the development process as follows:
Problem/Opportunity Identification - A. first step
Analysis - B. second step
Design - C. third step
Development - D. fourth step
Testing and Installation - E. fifth step
The SDLC is a structured methodology used for the development of software systems and involves several stages from initial problem identification through to the final deployment and maintenance of the solution. In the design process, after evaluating solutions and selecting the best design, as in the example of choosing a solar still for desalination, the team develops a detailed design through prototyping, testing, and refinement. This approach is typically iterative, sometimes referred to as a spiral design process, and may require several iterations as prototypes are created, tested, and reviewed to enhance the design.

Answer:
c. organizing observations into distinct groups based on a measure of similarity
Explanation:
In the field of data science and machine learning, clustering is a technique that is used to identify sub-groups within a data set. This subgroups are called clusters because they share similarities. K-means is one technique of clustering where the algorithm iteratively tries to divide the data into a pre-defined K subgroup. k-means ensures that each data-point belongs to only one sub-group (cluster) and data-points in same cluster are as similar as possible.
K-means clustering is the process of organizing observations into distinct groups based on a measure of similarity.
Explanation:K-means clustering is the process of organizing observations into distinct groups based on a measure of similarity. It does not reduce the number of variables or estimate the value of a continuous outcome variable, nor does it agglomerate observations into nested groups. The algorithm assigns each point to exactly one cluster based on their attributes, aiming to create the most compact clusters possible.

At one college, the tuition for a full-time student is $8,000 per semester.
It has been announced that the tuition will increase by 3% each year for the next five years.
Write a program with a loop that displays the projected semester tuition amount for the next five years as:
Answer:
Explanation:
We can use for-loop in python to calculate the tuition amount in the next 5 years. If the tuition is increasing 3% each year, in each loop we can multiply the amount by 1.03
tuition = 8000
for year in range(1,6):
tuition *= 1.03
print("The tuition amount after " + str(year) + " year(s) is $" + str(tuition))
In this exercise we have to use the knowledge of computational language in python to write the following code:
The code can be found in the attached image.
That way, to find it more easily we have the code like:
tuition = 8000
for year in range(1,6):
tuition *= 1.03
print("The tuition amount after " + str(year) + " year(s) is $" + str(tuition))

In Microsoft Excel, you have a large dataset that will print on several pages. You want to ensure that related records print on the same page with column and row labels visible and that confidential information is not printed. You should apply all of the following page setup options except which one to accomplish this?A. Set a print areaB. Print titlesC. Adjust the page breaksD. Change the print page order
Final answer:
To print related records on the same page with visible labels and exclude confidential data, set a print area, print titles, and adjust the page breaks. Do not change the print page order, as it does not help with these printing goals in Excel.
Explanation:
To ensure that related records print on the same page with column and row labels visible and that confidential information is not printed in Microsoft Excel, you would apply the following page setup options:
Set a print area to define the specific area of the worksheet that you want to print.Print titles to repeat specific rows or columns on every page, ensuring labels are visible across all printed pages.Adjust the page breaks to control where pages begin and end, which helps to keep related records together.The page setup option you should not apply is:
Change the print page order. This option changes the sequence in which pages are printed and does not assist in keeping related records together or ensuring that confidential information is omitted from the printout.By using the Page Layout tab, you can make adjustments like changing to landscape orientation or narrowing margins, which can help fit more data on each page. Using these settings effectively will help ensure your data prints out clearly and efficiently.
which of these variable declarations will the variable remain uninitialized unless it is explicitly initialized?1)Declaration of an instance variable of type int.2)Declaration of a static variable of type float.3)Declaration of a local variable of type float.4)Declaration of a static variable of type Object.5)Declaration of an instance variable of type int[].
Answer:
Option 3: Declaration of a local variable of type float
Explanation:
In Java programming, a local variable doesn't possess a default value. This means a value must be explicitly initialized to the local variable before it can be used.
The instance variable and static variable, on another hand, have default value which is dependent on the data type. For example, an instance or a static variable of type int is 0. If the data type is boolean, the default value is false.

What in the LAN for a small office, some user devices connect to the LAN using a cable, while others connect using wireless technology (and no cable). which of the following is true regarding the use of ethernet in this LAN?
Answer:
The ethernet protocol IEEE 802.3 is only meant for cable networks.
Explanation:
In this scenario, there are two types of networks, namely;
LAN and WLAN.
A LAN (local area network) is a network within a small area like a building, i which its workstation are connected using cables. The cabled network instantly use a protocol called Ethernet also known as IEEE 802.3.
WLAN (wireless local area network) is a small area network just like the LAN, but the difference is that its workstation are connected wireless (without cable). wireless networks uses wifi or 802.11a/n/g to connect to the network.

"On a TCP/IP network, which of the following are used by a router to determine the destination of a packet?"
Answer: Switching packets function.
Explanation: while the main function of a router is to forward packets to their target destination, this can be actualised by adopting a switching packet function.
Switching packet function is the process which the router uses to accept a packet from one interface and passes it to another interface. The main function the switching packet plays is to encapsulate the packets in the right data link frame type for the data link meant to be sent out.
The switching is about moving the packet to the right destination without been mistaken with the layer 2 switch function.
