Answer:
0.6535
Step-by-step explanation:
Given that during a one-hour period twenty-five customers buy gasoline at this station.
Let X be the no of persons out of these 25 who pay by cash.
X has two outcomes and each trial is independent of other.
Hence X is binomial (n=25, p=0.40)
Required probability
= 
=0.6535
Answer: y=0.60x+36.94
To find the equation we just set y equal to the 0.60 cents times x miles plus the 36.94 base fee. Any questions just ask. Cheers
