Teresa invested 3000$ in a fund for 5 years and was paid simple interest. The total interest that she received on the investment was 1350$. As a percentage, what was the annual interest rate of her investment?

9%

Step-by-step explanation:

To find the answer, you have to use the formula to calculate the interest rate:

r=(1/t)(A/P-1), where

r=rate of interest

A=accrued amount=3000+1350=4350

P=principal amount=3000

t=time periods=5

Now, you can replace the values:

r=(1/5)*(4350/3000-1)

r=0.2*(1.45-1)

r=0.2*(0.45)

r=0.09

According to this, the annual interest rate of her investment is 9%.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
