Mazyrski [523]
The best prediction for the number of regular spectators that the program will have in 6 years is obtained with the following formula:
 Pf = Po×(1-b) ^ t
 Where:
 Pf = final population
 Po = initial population
 b = decrease rate
 t = timpo in years
 So:
 Pf = 223.00×(1-0.047) ^ 6
 Pf = 167,056
 The answer is the last option.

galben [10]

Answer:

6.13%

Step-by-step explanation:

We are given an investment of $8000 deposited for 4 years. We have to find the effective annual yield for which we will need the interest rate and the compounding period.

Annual interest rate compunded quarterly, r = 6% = 0.06

Compounding period is quarterly, n = 4

Annual EffectiveYield =  (1+\frac{r}{n})^{n}-1\\=(1+\frac{0.06 }{4})^{4}-1

= 0.0613

The annual effective yield is 6.13%
