Lesson 13: Using Graphs to Analyze Data Unit Test
Math 8 B Unit 3: Using Graphs to Analyze Data
I need answers and i need them now!! but please put the right answers cause i suck at this math.
@Ms. Sue, I hope you know that you and your school are the reason i cant sleep at night and stay up thinking I'm a failure, I hope you stub your toe every day for the rest of your life. disrespectfully.
Don't give the letters for a unit test, give the actual answers since they change it around.
is raspy wrong?
you at this english, too
Mrs. Sue, how do Connexus students will survive since the lesson readings are not that helpful for math and every other subject? If I spend 2 days on the lesson still I will not understand so then I move on to watch khan/youtube videos.
You better be happy with these answers it took me about half of a day to finish the test and I got a 65.4%. BUT, these are all correct. God bless have a fantastic day!!!
