Use the simple interest formula to find the interest earned and the ending balance. I = Prt 1. $270 at 9% for 3 years

$72.90 is the interest earned

Step-by-step explanation:

The appropriate formula is i = prt, where r is the annual interest rate expressed as a decimal fraction.

Here, i = ($270)(0.09)(3 yr) = $72.90 is the interest earned

Step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
