Shown below.
Step-by-step explanation:
The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:
Number: 0 1 2 3 4 5 6 7 8 11 12
Frequency: 5 16 20 14 3 5 4 4 2 1 1
The probability of an events, say <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.
Compute the probabilities of 0 - 12 hurricanes each season as follows:
Number Frequency Probability
0 5 0.07
1 16 0.21
2 20 0.27
3 14 0.19
4 3 0.04
5 5 0.07
6 4 0.05
7 4 0.05
8 2 0.03
11 1 0.01
12 1 0.01
Total 75 1.00
Answer:
5.7% per year
Step-by-step explanation:
For an ordinary annuity, the final amount can be calculated by:
Where A is the final amount, R is the value invested monthly, r is the annual interest, n is the number of months in a year, and t the time in years. So:
(\frac{(1+\frac{r}{12} )^{156}-1}{\frac{r}{12} }) = 230.39
(\frac{(1+\frac{r}{12} )^{156}-1}{r}) = 19.2
Solving that in a graphic calculator,
r = 0.057
r = 5.7% per year
