19. the population of a small town was 10,800 in 2002. since then, the population has decreased at a
rate of 2.5% each year. write an exponential function to model the situation. select the correction
equation.
a. p=10800(0.975)'
b. p=10800(0.25)'
c. p=1080(0.975)'
d. p=10800(1.025)'

Step-by-step explanation:

There was a population of 108000 in a small town in 2002. Since then, the population has decreased at a  rate of 2.5% each year.

Therefore, the population is decreasing at a compound rate of 2.5% each year.

Now, using the formula of compounding we can write if p is the population after t years, then  

⇒ (Answer)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
