Suppose you are doing a study on a population of 195 iguanas at a zoo. you take a random sample of 20 iguanas. which would not be a characteristic of the sample group? a) the age of the sample group of iguanas. b) the weight of the sample group of iguanas. c) the length of the sample group of iguanas. d) the total number iguanas at the zoo.

D) The total number of iguanas at the zoo. This was already stated in the question.

Step-by-step explanation:

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
