Answer:
0.4353 = 43.53%
Step-by-step explanation:
The times are exponentially distributed, so let's call n the mean, and x the time of transaction. The times of the transaction occurs in a certain time is:

So, the probability that a car complete the transaction in less than 4 minutes, is 1 less the times it does it at 4 minutes:
P = 1 - 
P = 0.4353
P = 43.53%
Answer:
Slope=3
Step-by-step explanation:
Using the points (0,3) and (1,3) we can use the slope formula.
m=rise = y2-y1
----- --------
run. x2-x1
or. m=3 = (3-0) = 3 = 3
- ------ -
1 (1-0) 1
