Homework Questions? Ask a Tutor for Answers ASAP
What are the questions?
Can you do it later today? Or do you have to do it right now?
Why don't you write back sometime this evening, after 8 or so. That way if I can't help, there will be many other experts online.
I'm pretty busy now.
You can post what you have, but since I haven't seen it I can't guarantee that I'll know it. What exact topic is it going to be about?
Ok, well you can post it.
I'm just worried that if I can't do it, for some reason, that you will be out of luck.
We need more info for #2. Here are the ones I am sure of. Please give me info for #2, and possibly post the other ones in a new thread.

Here is 2:
1 - 0.01 -0.04- 0.37 -0.34
I'd rather not give you the wrong answers, so can you post the others in a new thread?
Oh, I had opted out so that other experts can try to answer these.
There are new questions? Are they going to be similar to these? If so, I might not be able to do them all...
Here are the ones I can help with! I need more info on #2.

Please give me more information about problem #2.
I'm not sure about 8, and I need that figure for #2.
Ok, the area between -1.13 and 2.03 is:
But without seeing the graph, I can't be positive that is what you are looking for.
