In the summer a large pool evaporates water at 15% per day. if the pool starts out with 25,700 gallons of water, which function models the pool’s loss of water?

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

where

y ----> represent the pool’s loss of water

x ----> the number of days

a is the initial value

a=25,700 gal

b ----> is the base

r=15%=15/100=0.15

b=(1-r)=1-0.15=0.85

The function is equal to

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.
