what is the mean height in a graph?
would it be the tallest or what I'm confused.

The mean height in a graph is the average height. So to work this out, you add the value of all of the heights together e.g. 2+3+4+3 = 12 then divide by the amount of heights , this case in my example  4, to get 3 as a mean of those heights.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
