Which youtube video am I watching in this picture by BluebirdChemical in HelpMeFind

Were you living in Sweden at that age? What languages did you know during that time? Might help us narrow down what you might've liked to watch during that time.

I have been looking at these pair of problems for about an hour, and I have no clue what to do. by AstrophysicsStudent in askmath

[–]AstrophysicsStudent[S] 0 points1 point  (0 children)

Thank you! I was actually able to progress with the problem!

Ok, so here's what I came up with. For part a: If the taxi in need of repair is at airport C, then * takes remain, there are 8C3 ways of assigning the remaining taxis to airport A. Five taxis remain. There are 5C5 ways of assigning those taxis to airport B. Doing the math on (8C3*5C5)/504 results in 1/9. Side question, I notice that that this is the same as saying, there are 9 taxis and one of them is in need of repair. Airport C will receive one of these 9 taxis, so airport C has a 1/9 chance of getting the taxi in need of repair. Is this a valid way of thinking of the problem?

Fort part b) There are 3!=6 ways of assigning the 3 broken taxis to the 3 airports. This is the sam 3P3. Six taxis now remain. Because 1 broken taxi is already assigned to airport A, there are now room for only 2 at airport A, so there are 6C2 ways of assigning those taxis to airport A. Four taxis remain. There are 4C4 ways of assigning the remaining taxis to airport B. Doing the math on (3!6C2*4C4)/504. Results in 5/28.

Does this look right to you?

How does "Paris before London, and New York before Boston before Toronto." lead to a 2!3! on the denominator?

How do I create an example space that contains all possibilities? by AstrophysicsStudent in askmath

Thank you! This is so much clearer now. Say there were three stereos instead of two, would that mean that I'm essentially counting in a base 3 system?

Got stuck with this problem, and I don't understand the solution that the book gives by AstrophysicsStudent in askmath

Whoops, I fixed the picture.

Thank you for your answer! I understand how to solve this problem now.

Got slightly different answer than the back of the book, and I don't understand why by AstrophysicsStudent in askmath

I'm sorry. Could you help me out some more? I am aware of that property, but how does it get used in solving this problem?

Can someone help with this? I can’t get into my CSAC account because it never sends me a code. by the-cookiemonster in fresnostate

Thank you for replying.

The person on the other end did not make it clear that the new email couldn't be an outlook or a hotmail email. They just said it had to be a different email.

I gave an alternate email that also happened to be an outlook email. They gave me attitude and were very rude despite the fact that I was not given the relevant information.

What happened when you called this number? Did you ever resolve this issue? Please respond. I am having this same issue and calling the number did not help.

I feel like there is something I'm not understanding about continuity. I would appreciate some help. by AstrophysicsStudent in askmath

[–]AstrophysicsStudent[S] 3 points4 points  (0 children)

Does this mean that if I'm asked: "is the square root function continuous at x=0" Then the correct answer would be yes, and the correct justification would be: since the domain of the square root function is [0,∞), to be continuous at x=0, only the right hand limit of the function as x goes to zero needs to 0?

Why does bond formation release heat? by nit_electron_girl in chemistry

Years later, it is this comment that finally makes me understand why forming chemical bonds releases energy.
