Answer:
0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.
Step-by-step explanation:
We have the mean during a time-period, which means that the Poisson distribution is used to solve this question.
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
 is the mean in the given interval.
 is the mean in the given interval.
A service center receives an average of 0.6 customer complaints per hour. 
This means that  , in which h is the number of hours.
, in which h is the number of hours.
Determine the probability that exactly four complaints will be received during the next eight hours.
8 hours means that  .
.
The probability is P(X = 4).


0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.
 
        
             
        
        
        
Answer:1 computer : 8 students
Step-by-step explanation:
if there are 9 computers it would originally be 9 : 72 but that can be reduced since 9 is a factor of 72.

Adding together the shorter two sides results in 17 m.  If these two sides were laid end to end, the sum of their sides (17 m) would be less than the length of the third side.  Thus, NO triangle could be constructed with this set of line segments.
