The graphs shows the amount of a chemical in a water sample at different times after it was first measured. Select all statements that are true. Group of answer choices After 4 hours, there were 100 mg of the chemical in the water. The amount of the chemical in the water sample is decreasing exponentially. The amount of the chemical in the water sample is not decreasing exponentially. When it was first measured, there were 2,000 mg of the chemical in the water sample. It is not possible to tell for certain whether or not the amount of the chemical is decreasing exponentially

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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
