Answer:
$1,080
Step-by-step explanation:
30,000*1.2%=360
360*3=1,080
Using the formula for the nth term of an arithmetic sequence we can write:
80 + (n - 1)2 = 65 + (n - 1)5
80 + 2n - 2 = 65 + 5n - 5
3n = 18
n = 6
The answer is 6 months.
Answer:
Roll two dices
Step-by-step explanation:
Every dice rolled has two chances of six of winning by showing a 1 or 2, which is the same as one chance of three.
On the opposite, you have four chances of six of loosing by getting a 3,4,5 or 6, which is the same as two chances of three.
Since the chances of loosing are bigger than the ones of winning, every roll makes it more probable of getting a 3,4,5 or 6, so you need to roll as few dices as possible, in this case two is the minimum allowed.
