    Note that it doesnt matter what approach we apply to the ratio: Ratio of: tagged : non tagged 8 : 22 Let x be the number of fish be in the tank after 50 added before 30 taken So the ratio will be: 50 : (x-50) Solve for x you get x=187.5

    Probability

    Simple: Of the 8 fish we get 30 are tagged, hence we can assume the ratio of tagged : non tagged is: \frac{8}{30} Let x equal the number of fish in the damn after the fish were added: Ratio of the tagged: non tagged should be the same -> \frac{8}{30}=\frac{50}{x} \\ \\ \therefore x=187.5...

    The Loaded Dog: HSC exams - Sun Herald

    Re: The Loaded Dog: HSC exams - Sydney Morning Herald No one is asking you to compete, and I apologise for the extensive use of 'deal with it' but in reality competition is a part of life and people will find a way to compete with other people in order to feel more powerful and no amount of...

    The Loaded Dog: HSC exams - Sun Herald

    I do agree that Competition has its flaws, political competition is negative because it creates squabbles over things like oil and money etc. But in the most part competitiveness is necessary whether positive or negative (and at the human level its a lot of the time positive)

    The Loaded Dog: HSC exams - Sun Herald

    Re: The Loaded Dog: HSC exams - Sydney Morning Herald You are right in a way....kind of, but it actually benefits my overall argument that you are saying its harder to get a job nowadays hence stressing the more importance on the HSC. And plus from where my parents and many other people's...

    The Loaded Dog: HSC exams - Sun Herald

    Re: The Loaded Dog: HSC exams - Sydney Morning Herald Ok explain how non-competitiveness will lead you anywhere in life? We live in a capitalistic society dog-eat-dog world if you will. Only the top are the ones who survive (not literally but for the rest of the post I will refer to...

    Re: The Loaded Dog: HSC exams - Sydney Morning Herald It is a cultural perspective that spans among many cultures and are the common targets for stereotypes when it comes to pressure applied for the HSC.

    The Loaded Dog: HSC exams - Sun Herald

    Re: The Loaded Dog: HSC exams - Sydney Morning Herald No I am not using anecdotal evidence, read my post.
