What I have tried:
Can anyone check if those answers are correct?
This is a practice midterm, but my professor didnt give us the answers.
Thanks!
And is there some particular reason you're trying to get other people to do your homework for you? Read: Never going to happen.
For all we know, you just highlighted random answers in the hope that someone naive is going to correct you, giving you all the answers.
