The answer is most likely 15ft.
1/2 × 1/2
1/4 or 25%
probability of tails both times
32, 38, so on. So its +4 then +8 then +12 +16 +20....
25 because you do 19 squared plus 16 squared equals 617, you do 617 rooted. It’s called pythagorus.
On the account with interest compounded annually, the account balance will be
P*(1 +r)^t
4500*1.06³ = 5358.57
so the interest earned will be
5358.57 -4500 = 859.57
On the account with simple interest, the interest earned will be
I = Prt
I = 4500*.06*3
I = 810.00
The total interest earned on the two accounts will be
$859.57 +810.00 = $1669.57 . . . . . . . . selection A
