Plz hurry and i need the answer by today for hw the amount of money in a bank account increased by 12.5% over the last year. if the amount of money at the beginning of the year is represented by n, which expression represents the amount of money in the bank account after the increase? a) n +0.215n b) n+ 21.5n c) 0.215n d) 21.5n

That should be .125n, so i guess C? You have the numbers typed wrong, it should be 0.125n, not 0.215n :')

The problem ask to explain the use if the normal curve to compare that score to the population and the best explanation is that the normal curve depends on a lot of assumptions. if the population score are normally distributed, we will know its mean and standard deviation, so can tell that our particular individual's row score falls on that distributions.
