Answer:
Someone can make a histogram instead of a bar chart if distributions of variables are need to be represented and if data is quantitative.
Explanation:
Histograms are drawn to represent distributions of variables whereas bar charts are used to compare various variables. Histograms plot quantitative data whereas bar charts plot categorical data.
So, someone can make a histogram instead of a bar chart if distributions of variables are needed to be represented and if data is quantitative.
he will need a microphone, it is a recording device.
Answer:
// program in Python to check perfect number
#function to find number is perfect or not
def is_Perfect_Number(n):
#total variable
tot = 1
i = 2
#sum of all divisor of number
while i*i<=n:
if n%i==0:
tot = tot + i + n/i
if tot == n and n != 1:
return 1
i = i+1
return 0
#read until user enter a perfect number
while True:
#read integer
num = int(input("Input an integer: "))
#call the function
if(is_Perfect_Number(num)):
print(num,"is perfect number")
#if perfect number break
break
else:
print(num,"is not a perfect number")
#ask again
print("try again.")
Explanation:
Read number from user and then call the function is_Perfect_Number() with parameter "num".This will find the sum of all divisor of number.If sum is equal to number then it will return 1 else return 0.If the number is not perfect then it will again ask to enter a number until user enter a perfect number.
Output:
Input an integer: 24
24 is not a perfect number
try again.
Input an integer: 28
28 is perfect number
The limpel-ziv (lz77) compression technique is used by the GNU zip (gzip) tool to produce a compression ratio of 60–70%.
<h3>How do methods for data compression function? Describe the LZW algorithm.</h3>
Compression methods lower the amount of memory needed to hold pictures and the number of bytes needed to represent data. Compression improves the amount of data that can be delivered over the internet and enables the storage of more photos on a given media.
Abraham Lempel, Jacob Ziv, and Terry Welch developed the table-based lookup technique known as LZW compression to compress a file into a smaller file. The TIFF image format and the GIF image format are two frequently used file formats that employ LZW compression.

Answer:
cables, towers, and underground tubes
Explanation:
Its certainly the above one, and through this internet service is being provided. So internet service is self-understood, and what ISP firstly provides are cables, underground tubes, and the towers. And it is only these all through which the ISP provides internet service. And remember we are in this question dealing with the infrastructure and not the services or products. Hence, phone service, websites, and files, as well as the emails, search engines, and the videos, are not the solution here as they are not the infrastructure. And ISPs never provide the computers, ethernet cables or keyboards.
Hence, the correct answer is as mentioned in the answer section.
