Answer: D. 0.1217
Step-by-step explanation:
Given : The probability that a car will have a flat tire while driving through a certain tunnel :p=0.00005.
n= 14000
Then, the mean number of cars will have a flat tire while driving through a certain tunnel = np

Poisson Distribution Formula : 
For x= 2

Hence, the required probability = 0.1217
200 meters per minute.
A minute is 60 seconds. 60 divided by 3 is 20. 20 Times 10 is 200.

Answer:
t = -1
Step-by-step explanation:
8 + 9t - 3 + 4
Combine like terms
(8 - 3 + 4) + 9t
9 + 9t
9t + 9
Get <em>t</em> by itself
9t + 9 = 0
-9 -9
9t = -9
Divide both sides by 9 to find <em>t</em>
t = -1
