Answer:
10.153 years
Step-by-step explanation:
The future value of such an investment is given by ...
FV = P·(1 +r/12)^(12t)
where P is the principal invested, FV is the future value of it, r is the annual interest rate, and t is the number of years.
Dividing by P and taking the log, we have ...
FV/P = (1 +r/12)^(12t)
log(FV/P) = 12t·log(1 +r/12)
Dividing by the coefficient of t gives ...
t = log(FV/P)/log(1 +r/12)/12 = log(3000/2000)/log(1 +.003333...)/12 ≈ 121.842/12
t ≈ 10.153 . . . years
Step-by-step explanation: To draw a line plot for the data shown here, first begin by drawing a line.
Next, notice that the smallest number in our data set is 10 so we begin our line plot at 10. Next, notice that the greatest number in our data set is 22 so we continue our line plot until 22.
Now we fill in the numbers in between.
So we have 10 which we already have, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, and 22.
Now, notice that there is one 10 in our data set so we put one x above 10. Next, notice that are no 11's, no 12's, and no 13's in our data set. So we put no x's above 11, no x's above 12, and no x's above 13. Next, notice that there is one 14 in our data set so we put one x above 14. Now, notice that there is one 15 and one 16 in our data set so we put one x above 15 and one above 16. Since there are no 17's or 18's in our data set, we put no x's above 17 and no x's above 18. Finally, notice that there is three 19's, no 20's, one 21, and one 22 in our data set so we put three x's above 19, and one x above 21 and 22. We put no x's above 20.
