Answer:

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

Answer:
1/56
Total letters are 8
probability of first selecting c is 1/8 and since it's not replaced, probability of selecting e is 1/7
Total probability= 1/8*1/7=1/56
Therefore, total probability is 1/56
Step-by-step explanation:
7 1/2 acres = 15 / 2 acres and a third of this is 5/2 or 2.5 acres for grazing animals.
7 1/2 acres = 15 / 2 acres and a fifth of this is 3/2 or 1.5 acres for growing vegetables.
49/100 I don't know how specific you needed it to be.
