Answer 1

Answer:

A newsgroup is an Internet-based discussion around an individual, entity, organization or topic. Newsgroups enable remotely connected users to share, discuss and learn about their topic of interest by exchanging text messages, images, videos and other forms of digital content.

Answer 2

Arithmetic mean of given data is 41.3

Explanation:

• Given Marks obtained by 10 students are 30, 62, 47, 25, 52, 39, 56, 66, 12, 24

• The Sum of all of the numbers of a group, when divided by number of items in that list is called Arithmetic Mean.

• It simply includes taking the summation of a bunch of numbers, then dividing that result by the count of the numbers used in the series.

Arithmetic mean = {Sum of all Observations} ÷ {Total number of Observations}

Sum of all marks = 30+62+47+25+52+39+56+66+12+24 = 413

Total number of students = 10

So, Arithmetic mean = 413/10

                      = 41.3

Hence, Arithmetic mean of given marks is 41.3.
