How do you determine when a counting problem involves a permutation or a combination?

1 answer:

6 0

The difference between combinations and permutations is ordering. With permutations we care about the order of the elements, whereas with combinations we don't. For example, say your locker “combo” is 5432. If you enter 4325 into your locker it won't open because it is a different ordering (aka permutation).

Which value of x would make NO II KJ? 1 6 8 10

We sketch the two similar shapes and they are as shown in the attachment. We want to write corresponding side's length in ratio

$LN : LK = x-3 : (x-3+x+2) = (x-3) : (2x-1)$
$LO : LJ = (x-4) : (x-4+x) = (x-4) : (2x-4)$

Writing the two ratio as fraction gives
$\frac{x-3}{2x-1} = \frac{x-4}{2x-4}$

Cross multipliying gives $(x-3)(2x-4)=(x-4)(2x-1)
$
