Two savings accounts were each opened with a $6,000 deposit. account a earns compound interest at a 2% annual interest rate compounded yearly. account b earns simple interest at a 2% annual interest rate. no other deposits or withdrawals are made from the accounts for 3 years.

what is the difference in interest earnings between the two accounts after 3 years?

account a will earn approximately $360 less in interest than account b.
account a will earn approximately $7 less in interest than account b.
account a will earn approximately $360 more in interest than account b.
account a will earn approximately $7 more in interest than account b.
both accounts will earn the same amount of interest.

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
