A true/false test has 6 questions. If a student were to guess the answer to
each question, how many different ways would there be to answer the
test? *

There are 2 ways to answer each true-false question and there are six questions in total, if he redid the test twice and answered half true and half dflase then retook and flipped it, by answering what he answered true now false and what he asnwered false now true. But if teh test is blank and he is hust starting there would be 12 possible ways to answer. The test itself would have two possibilities for each question and six questions so 12 possible ways to answer it.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4
