Answer 2

hi,

I solved your question on a notebook and add the attachment so you can go and check the answer. also i think that the number 18 in the list that you wrote was by mistake because there were no class interval given the question with this number but i added it and solve the question.

if you agree with the answer then please mark me as a brainlist.
