This homework will prepare me for my upcoming Algebra 2 Statistics test. I must show set up and I can use the functions on my calculator to assist me. I cannot just give the answer. I need to show the set up and I want to understand it. Thank you in advance! How many choices of 3 burrito toppings are possible if there are 9 toppings to choose from?
yes, I did use my calculator. I divided 9 factorial over 6 into the calculator and got 504. Not sure what I am doing wrong. This will affect the rest of the problems that I am trying to solve. The next one is How many 5 letter passwords can be made if each letter in the alphabet can be used only once? i got 7,893,600 using my calculator. I want to tell you how much I appreciate your time in helping me
Ok I got it, now I understand how you get the answer.I forgot to divide it by the 3 times 2.

Can you help me with another problem? How many 5 letter passwords can be made if each letter in the alphabet can be used only once? i got 7,893,600 using my calculator. I want to tell you how much I appreciate your time in helping me.
Ok , I really understand how you are getting these, but I had a review that my teacher gave the answers to and I have used it to figure out these questions. This question, my teacher said the answer was 8,648,640 ((this isnt part of what I need ,but it is what I am using to do this homework??)) Just trying to figure out what he is asking us to do ..... so the question he gave us the answer of 8,648,640 was---- For a segment of a radio show, a disc jockey can play 7 songs. If there are 13 songs to choose from , in how many ways can this segment be arranged?
Oh, sorry to confuse you but I have to take back my last answer because after reading the question again I think it was a trick question. If you read it LITERALLY it says that you can only use each letter of the alphabet ONCE.
So, that means, 26/ 5 is FIVE with a remainder of one which doesn't count.
So the answer should be FIVE!!! I think it was a trick question.
Yes, it's five because if you can use each letter ONLY ONCE then the only way to do that is to just divide 26 by 5 which gives you 5 unique password, each with different letters.
Yes, the disc jokey answer is correct. I get 8,648,640 too. It's a permutation because order matters. In other words, the order that the songs are played matters.
No, it's a permutation because order matters. That is to say, you can choose two people but only one can be the manager and one can be the assistant. And you can choose THE SAME TWO people again, only this time the roles are reversed, the guy who was the manager is now the assistant, and vice versa. Does that make sense? That's why ORDER MATTERS, in this problem.
So, it's 13P2 = 156 LOL, it's the same answer you got, but you did the combination wrong. 13C2 = 78, not 156.
So, the answer is 156 using PERMUTATION, not combination.
got it! I think my session is expired , where can i find you for more help. I guess I have to make it official and sign up? but I only want help from you. How do I do this. I have about 8 more to do that I have already worked out. Thanks
I was laughing because it was such a coincidence that you got the right answer by miscalculating the combination. I've never seen that before. It just took me by surprise.
Ok, you can send me a private request to do a problem. I would bid on it. If you accept my bid then I'll do the 8 problems you want. I'll only charge you $5. Sound fair?

It's called inviting a tutor to answer a problem. I'm not exactly how you do that with Studypool. But I get invitations all the time from students and it pops up on my message board as a student has invited me to answer a question.
ok thanks :) funny thing is I don't know how I got the 156 neither, but I got it. I have spent so much time working on this because it will probably count as a take home test grade so the teacher expects us to get 100! and although I have done all of it , I just want to be sure that they are correct. Just need a little guidance. Going to request that now. thanks
Ok I finally got through it , I see two views although I just sent it to only you I thought. Please check. I will pay you 10 instead of 5 for now. Thanks
When I hit to see your reviews the most recent question that I see is mine with the heading burritos and I see the whole chat. Not sure that is good. Maybe only visible to me? I do know that these questions are now paid and private though. Just wondering if you could go to your reviews later.maybe delete the chat that automatically got on there if it is not private , I would like it to be , thanks. Ok so just so you know , I did accept and just paid :)
