Explanation:
The apply method has the axis argument which enables it to use the applied function either across the rows or columns, by passing the value 1 to the axis argument, the mean of at each index is calculated, (across the column) such that the length of the AVG column is equal to the lengtb of the original dataframe.
The drop method is used in pandas to remove row or column entry from a dataframe. To remove columns from a data table, the value 1 is passed to the axis argument of the drop method. Hence, passing 1 to the axis argument removes all 6 columns leaving only the AVG column in result_df.

What happens when a dataset includes records with missing data?
Answer:
However, if the dataset is relatively small, every data point counts. In these situations, a missing data point means loss of valuable information. In any case, generally missing data creates imbalanced observations, cause biased estimates, and in extreme cases, can even lead to invalid conclusions.
It makes data analysis to be more ambiguous and more difficult.
Missing data is simply the same as saying that there are values and information that are unavailable. This could be due to missing files or unavailable information.
A dataset set with missing data means more work for the analyst. There needs to be a transformation in those fields before the dataset can be used.
Generally speaking missing data could lead to bias in the estimation of data.
A data scientist is a data expert who is in charge of data. He performs the job of data extraction, data analysis, data transformation.

Which of the following describes this capability?
a. Continuity
b. Adaptability
c. Vertical scaling
d. Horizontal scaling
Answer:
The description of this capability is:
d. Horizontal scaling
Explanation:
The capability that Brandon has achieved is horizontal scaling, which involves the increasing of the resources of cloud applications to meet his increasing demand for cloud services. Vertical scaling involves the addition or subtraction of power to a cloud server, which practically upgrades the memory, storage, or processing power. But to scale horizontally, more resources are added or subtracted. The purpose of horizontal scaling is to spread out or in the workload of existing resources and either increase or decrease overall performance and capacity.

Name them and explain the significance of each in the working of the computer. Why is a 64 bit processor better than a 32 bit processor
Answer:
CPU, RAM, and Storage
Explanation:
The three hardware components that are inside every computer and are essential for it to function are CPU, RAM, and Storage (HDD, SSD). CPU is basically the brain of the computer where everything is calculated. The RAM is the memory that stores temporary information. Lastly, the Storage device is where the entire operating system and persistent data will be saved and accessed from. 64-bit processors are better simply because they can access more memory at any given time and therefore allows it to manipulate more data at the same time.

Leo is planning the new backup strategy for a subsidiary his company is purchasing that does not currently have a backup strategy in place. He decides that a full backup should be run once per week. Once per day, everything that has changed since the last full backup will be archived. Once per hour everything that has changed since the last backup of any type will be backed up. Which of the following describes the backups that will be run every hour?
a. Differential
b. Variable
c. Incremental
d. Flexible
Answer:
C. Incremental backup
Explanation:
An incremental backup is a type of backup where the succeeding copies of the data is made up of only those positions that have changed since the previous or prior copies were made. Such backups are desired since they limit the usage of space for storage and these types of back ups are faster to do that the differential backup.
When we bring this explanation to this question, we can easily see that the backup that is being carried out is done on everything that has changed since the last backup (previous backup). Therefore this is an incremental backup.

Product firms make and try to market a certain product as a solution. But projects are creating a solution based on many product lines as well as selling them for specific needs or issues as such is.
Project-Based Software Engineering:
Software developers based on projects follow a service-oriented strategy. At one time, not only software but multiple projects are being developed, operated, and delivered. It accomplishes a software development process from requirement collection to testing and maintenance. It is carried out in compliance with implementation methods or specified period for achieving the software package meant for use.Product-Based Software Engineering:
A product-based business is a venture that produces a product that may or might not have software connections. Even before resulted in a demand, it will create or design its goods or applications ahead of time. Once the product is produced or applied, it is opened up for market use and only works if a client meets specific requirements and needs.

The enhanced for loop _____ Group of answer choices reduces the number of iterations necessary to visit all elements of an array prevents incorrectly accessing elements outside of an array's range can be used to replace any regular for loop while yielding less code creates a copy of an existing array and iterates through the copy's elements
Answer:
prevents incorrectly accessing elements outside of an array's range.
Explanation:
The enhanced for loop prevents incorrectly accessing elements outside of an array's range. This type of loop is also called a For Each Loop. This is because this loop automatically loops through each element in the given array and grabs that element, then it performs whatever instructions are inside of the loop's body to that element before moving on to the next available element. This way there is no numbered indexing that needs to be provided and therefore prevents the loop from accidentally trying to access an index that does not exist in the array.
Keely has an automation tool in place that runs a number of different processes for her and has for the last two years. All of a sudden it stops working and generates an error message that the account has been locked. Which of the following is the best possible reason why?
a. The password has expired.
b. The IP address of the server the process is typically accessing has changed. *
c. The ACL with the allowed list of users has changed.
d. Someone has tried to hack into the system using that account.
Answer:
b. The IP address of the server the process is typically accessing has changed
Explanation:
IP address stands for Internet Protocol address. It refers to a numerical value which is assigned to a every device which is connected to a computer network using the internet protocol for any communication.
Every device is allotted a unique IP address number.
In the context, Keely who works on an automation tool suddenly gets an error message that the account has been locked. This is mainly due to the changed in the IP address of the server that accesses the process.
The account gets closed or clocked whenever the IP address of the server changes.
Therefore, the correct option is (b).

The development of the modern computer system has been evolutionary. Discuss this phenomenon and further discuss how current trends in computing would impact future computer systems development
Answer:
The modern computer system has been evolutionary. Modern computers have allowed for us to complete hard tasks rather easily. With modern computers, we are able to calculate advanced equations with the click of a button. Trends in computing like RTX can rapidly improve performance, rendering, and tons of other graphical heavy actions. In September of 2018, we got the first RTX card, now in 2021, RTX has become exponentially better than what it was in 2018. With the modern computers comes quantum computers. Quantum computing is estimated to be 100 million times faster than any modern computer. IBM, the company to make the first computer stated that we are in the decade of quantum computing. And who knows? Maybe quantum computing will come sooner rather than later.

1. You purchase a new desktop computer that does not have wireless capability, and then you decide thar you want to use a wireless connection to the internet. Give two solutions to upgrade your system to wireless.
2. You are replacing a processor on an older motherboard and see that the board has the LGA1155 socket. You have three processors on hand: Intel Core i3-2100, Intel Core i5-8400, and Intel Core i5-6500. Which of these three processors will most likely fit the board? Why?a. 4.b. 5.c. 6.d. 7.
Answer: 1.) You can use a USB WiFi adapter, install a dedicated PCIe WiFi card, or upgrade to a new motherboard with built-in WiFi. (That's three solutions but just want to give you flexibility with your problem.)
Answer: 2.) None of the processors would fit because they all have different series sockets. (The i5 processors have LGA1151 sockets and the i3 has an LGA1156 socket.)
Explanation: 1.) Usb WiFi adapter, dedicated PCIe WiFi card, OR a new motherboard with built-in WiFi

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are:
1) If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.
2) If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.
3) If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.
4) The year is a leap year (it has 366 days).
5) The year is not a leap year (it has 365 days).
Some example leap years are 1600, 1712, and 2016.
Write a program that takes in a year and determines whether that year is a leap year.
Answer:
The program in Python is as follows:
year = int(input("Year: "))
print(year,end=" ")
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print("is a leap year")
else:
print("is not a leap year")
else:
print("is a leap year")
else:
print("is not a leap year")
Explanation:
This gets input for year
year = int(input("Year: "))
This prints the year, input by the user
print(year,end=" ")
Check if year is divisible by 4 --- step 1
if (year % 4) == 0:
If step 1 is true, check if year is divisible by 100 -- step 2
if (year % 100) == 0:
If step 2 is true, check if year is divisible by 400 -- step 3
if (year % 400) == 0:
If yes, print leap year --- step 4
print("is a leap year")
else:
If otherwise, print not leap year --- step 5
print("is not a leap year")
If step 3 is not true, print leap year
else:
print("is a leap year")
If step 1 is not true, print not leap year
else:
print("is not a leap year")
