I don't know because if I use these -4+-4 it gives me -8 not 8, and if I use this -4+4 it gives me 0, so I don't know, what do you think?

yea that is what I thought it was. Because -(-1) gives you a positive right?

Ok I have a question, does it matter if the integers are from smallest to largest, because I tried both ways and it gives me 2 different numbers.

ok my guess is that you subtract 300 from 2009 and you get 1709?

is that simplest form?

ok I see, so then it would be 24 males

Ok so then I think it would be 20 1/20, right, because the fractions add is 2/40 which reduces to 1/20? therefore making it 20 1/20 lbs????

How would you work the problem? I tried dividing and multypling and it gives the same answer?

so it is 76 shares?

Ok, but isnt 20 divided by 4/5 equal to 25 and therefore 25*5/4= 31 1/4

ok I see that so it would be 7 pieces, right?

So it is 25 lots not 31 1/4?

It doesnt say that is all that it gives.

Ok, I got that there are 105 15's in 1575 making the rest 105*8=840 105*7=735 right?

Ok how did you get 1.188

yea you are right

A. Ok there are 40 non-face cards and 4 seven cards, what do you mean do I add them and then divide by 52? B. I think the answer is 4/13, is that right?

thanks for your help

Would they both be 1/2?

What do you mean?

That P(A)= P(A and B)

A. yes there are 4 seven cards included in the 40 non-face cards, what does that mean do I divide 40 by 52?

so, because there are the same amount of even and odds wouldnt that make it a 1?

Oh.... I understand and see that now.

So say I got x=1/4 would I substitute it in for P(A through C)?

That P(B) should not be there???

Ok so then, A. would be 10/13 B. would be 4/13 RIGHT?? :-)

Alright I think I got it P(A)= 1/4 P(B)= 2/5 P(C)= 5/14 RIght?

Yes sorry about that

Ok I have not done any trig, but I think I kind of understand what you mean.. thank you.

oh ok... thanks
