Question 1169689
<font face="Times New Roman" size="+2">


You apparently copied and pasted from an online system.  These online systems are designed to prevent you from easily cheating on tests, so some of what you thought you copied does not paste.


If you want help here, you will have to do the work of typing the entire question with all of the data.  By the way, a four-part question is four questions. You are only allowed one question per post.  Read the rules.
