Step-by-step explanation:
13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25, 25, 25, 30, 33, 33, 35, 35, 35, 35, 36, 40, 45, 46, 52, 70.
a) Smoothing by bin means
Each bin has depth of 3
Dividing data into bins
so, Bin 1= 13, 15, 16
Bin 2= 16, 19, 20
Bin 3= 20, 21, 22
Bin 4= 22, 25, 25
Bin 5= 25, 25, 30
Bin 6= 33, 33, 35
Bin 7 = 35, 35, 35
Bin 8= 36, 40, 45
Bin 9= 46, 52, 70
Now, smoothing data by bin mean
so, Bin 1= 13, 15, 16 = (13+15+16)/3 = 15 Bin 1 = 15,15,15
Bin 2= 16, 19, 20 = (16+19+20)/3 = 18 Bin 2 = 18,18,18
Bin 3= 20, 21, 22= (20+21+22)/3 = 21 Bin 3 = 21,21,21
Bin 4= 22, 25, 25 = (22+25+25)/3 = 24 Bin 4 = 24,24,24
Bin 5= 25, 25, 30 =(25+25+30)/3 = 27 Bin 5 = 27,27,27
Bin 6= 33, 33, 35 = (33+33+35)/3 = 34 Bin 6 = 34,34,34
Bin 7 = 35, 35, 35 = (35+35+35)/3 = 35 Bin 7 = 35,35,35
Bin 8= 36, 40, 45 = (36+40+45)/3 = 40 Bin 8 = 40,40,40
Bin 9= 46, 52, 70=(46+52+70)/3 = 56 Bin 9 = 56,56,56
This technique is used to smooth the data. Data may have noise, using binning techniques we can remove noise from the data. It helps in providing more accurate results
b) How might you determine outliers in the data?
Outliers are the data that are abnormal to other data points. Outliers can be found by Box and whisker chart (box plot). Inter Quartile range can also be used to identify outliers
c) What other methods are there for data smoothing?
Other methods of smoothing data are
a) binning by boundaries
b) Exponential smoothing
c) Random walk
Smoothing by bin means with a bin depth of 3 involves dividing the data into bins of size 3, and replacing each value in the bin with the mean of the bin.
What is bin depth?According to the definition of equal depth binning, it divides the range into N intervals, each containing approximately the same number of samples.
The steps are as follows:
Bin 1: 13, 15, 16 → (13 + 15 + 16)/3 = 14.67
Bin 2: 16, 19, 20 → (16 + 19 + 20)/3 = 18.33
Bin 3: 20, 21, 22 → (20 + 21 + 22)/3 = 21
Bin 4: 22, 25, 25 → (22 + 25 + 25)/3 = 24
Bin 5: 25, 25, 30 → (25 + 25 + 30)/3 = 26.67
Bin 6: 33, 33, 35 → (33 + 33 + 35)/3 = 33.67
Bin 7: 35, 35, 35 → (35 + 35 + 35)/3 = 35
Bin 8: 35, 36, 40 → (35 + 36 + 40)/3 = 37
Bin 9: 45, 46, 52 → (45 + 46 + 52)/3 = 47.67
Bin 10: 70 → 70
(b) Data outliers can be identified using a variety of methods, including:
Z-score: For each data point, compute the Z-score, and consider any data point with a Z-score greater than 3 or less than -3 to be an outlier.The Tukey method: Calculate the data's interquartile range (IQR), and consider any data point that is more than 1.5 times the IQR below or above the first quartile to be an outlier.Visual examination: Plot the data and look for any values that seem out of place with the rest of the data.(c) Other data smoothing methods include:
Moving average: Replace each data point within a specified window with the average of itself and its neighboring data points.Fit a polynomial to a moving window of data points and replace each data point with the value of the polynomial at that point using the Savitzky-Golay filter.Exponential smoothing: Assign each data point exponentially decreasing weights, with more recent data points receiving higher weights, and replace each data point with a weighted average of itself and the previous smoothed value.Thus, this way, determine outliers in the data.

f = open("numbers.txt", "r")
lst = [int(x) for x in f.read().splitlines()]
sum = 0
for x in lst:
----sum += x
I had to add the four dashes to maintain the structure of my code. You can replace them with spaces. Also, I wouldnt recommend having a variable named sum because python has a built in function named sum. You can test this code by putting print(sum) at the end of the code.

Car owners are worried with the fuel consumption obtained by their vehicles. A car owner wants trail of several
tankful (the amount a tank can hold) of fuel by recording kilometers driven and gallons used for each tankful. Write
a program that will take input the kilometers driven and gallons used for each tankful. Your program should compute
and display the kilometers per gallon obtained for each tankful. After processing all input information, the program
should compute and display the combined miles per gallon obtained for all tankful.
Answer:
Program written in Python:
Please note that -> is used for indentation purpose
count = int(input("Number of vehicles: "))
totaldist = 0; totalgall = 0
for i in range(count):
-> gallon = int(input("Gallons: "))
-> distance = int(input("Kilometers Travelled: "))
-> totaldist = totaldist + distance
-> totalgall = totalgall + gallon
-> rate = distance/gallon
-> print("Kilometer/Gallon: "+str(rate))
print("Miles/Gallon: "+str(totaldist * 1.609/totalgall))
Explanation:
The program uses loop to ask for distance and gallons used by each vehicles.
At the end of the loop, the program divided the total distance by all vehicles in miles by total gallon user by all vehicles
[This line prompts user for number of vehicles]
count = int(input("Number of vehicles: "))
[This line initialised total distance and total gallon to 0]
totaldist = 0; totalgall = 0
[This iterates through number of vehicles]
for i in range(count):
[This prompts user for gallons used]
gallon = int(input("Gallons: "))
[This prompts user for distance traveled]
distance = int(input("Kilometers Travelled: "))
[This calculates total distance]
totaldist = totaldist + distance
[This calculates total gallons]
totalgall = totalgall + gallon
[This calculates the rate by each vehicles: kilometres per gallon]
rate = distance/gallon
[This prints the calculated rate]
print("Kilometer/Gallon: "+str(rate))
[The iteration ends here]
[This calculates and prints the rate of all vehicles. The rate is calculated by dividing total distance in miles by total gallons used]
print("Miles/Gallon: "+str(totaldist * 1.609/totalgall))

You know that the number must end in 6 or 1 to get a left over of 1 when divided by 5. Six won't work because 2 divides evenly into a number ending into 6.
So the number ends in 1.
21 doesn't work because 3 divides into 21 evenly.
31 doesn't work because 7 does not divide into it.
41 doesn't work. 41 is prime. 7 won't divide into it.
51 is divisible by 3
61 seven does not evenly divide into 61.
71 seven leaves a remainder of 1
81 7 leaves a remainder.

If a document is stored on a file server but team members can edit the document anonymously, the content on the file server is considered to be a: c. shared content with no control.
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives. Thus, it offer or avail individuals and businesses a fast, effective and efficient way of providing services to their clients over the internet.
Generally, cloud computing comprises three (3) service models and these are;
Infrastructure as a Service (IaaS). Software as a Service (SaaS). Platform as a Service (PaaS).A file server can be defined as a type of computer that centrally stores, manage and fetch all data files (audio, image, text and video) as they are requested over the internet or network by end users (clients).
An access control refers to a security technique that is used to determine whether a user has the minimum requirements (credentials) to access, use or view resources such as documents on a computer by ensuring they are who they claim to be (authentication).
In this context, when a document (content on a computer) is shared on a file server without the implementation of an access control, the file can be anonymously edited by end users because it won't ask or request for authentication.
However, a shared content on a file server with an access control would only grant permission to authorized users while denying other users access to edit or modify its content.

Write a function that returns a pointer to the maximum value of an array of float ingpoint data: double* maximum(double* a, int size) If size is 0, return NULL.
Answer:
double * maximum( double arr[], int size){
int max = 0;
if ( size == 0){
return 0;
} else {
for (int i = 1; i < size; i++){
if (arr[i] > arr[0]){
max = arr[i];
} else {
max = arr[0];
}
}
return max;
}
}
Explanation:
The C++ source code above returns the maximum value of an array as a pointer. The function accepts two parameters, the array in question and the size of the array. The for loop iterates over the items in the array and checks for the largest, which is returned as a pointer since the function "maximum" is defined as a pointer to the floating-point number memory location.

Hardware and software collaborate to enable a user to perform a function. The physical components of a computer system, such as the central processing unit (CPU) and memory, are referred to as hardware.
What is CPU?CPU is an abbreviation for Central Processing Unit, which is the main component of a computer system that is in charge of executing instructions and processing data.
The CPU is often referred to as the computer's "brain" because it performs the majority of the calculations.
When a computer user performs a function, the software sends instructions to the hardware, which then executes the instructions and performs the function.
When a user types on a keyboard to create a document, for example, the keyboard sends signals to the CPU, which processes the input and sends the output to the software application to display on the screen.
Thus, in this way, hardware and software are interdependent and work together to enable a user to perform a variety of functions on a computer system.

What is Pre-writing or surveying?Pre-reading or surveying is the process of skimming a text to locate key ideas before carefully reading a text (or a chapter of a text) from start to finish. It provides an overview that can increase reading speed and efficiency.
Reading strategies aim to facilitate the understanding of difficult texts. These strategies are very effective and can facilitate not only reading but also the interpretation of the text. Among the reading strategies, we can mention the use of context clues, which facilitate the understanding of difficult and unknown words.
Synthesizing the text is also a very beneficial strategy, as it allows the text to become smaller, more objective, and direct. Reading strategies should be used even by people who find it easy to read texts with different difficulties, as it allows the text to be understood in a deeper and more complete way.
