-- Look for a common factor of both the top and bottom numbers.
==> 5 is a common factor of 45 and 100 .
-- Divide the top and bottom numbers by their common factor.
==> 45/100 = 9/20 .
-- Look for another common factor of both the top and bottom numbers.
==> The only common factor now is ' 1 ' .
==> That means the fraction is now as simplified as it can get.

3x*3x=9x^2
3x*-8=-24x
6*3x=18x
6*-8=-48
9x^2-24x+18x-48
9x^2-6x-48
Mean (average) - 13027.2
Median (middle number) - 12,200
Mode (occurs the most often) - none of the numbers occur more than once?
Mean would be the best to predict because it is the average miles Gina has driven over the past five years
Answer:
a) 0.3125 per hour
b) 2.225 hours
c) 8.9 hours
d) 12.1 hours
e) 80%
Step-by-step explanation:
Given that:
mean time = 3.2 hours, standard deviation (σ) = 2 hours
The mean service rate in jobs per hour (λ) = 2 jobs/ 8 hour = 0.25 job/hour
a) The average number of jobs waiting for service (μ)= 1/ mean time = 1/ 3.2 = 0.3125 per hour
b) The average time a job waits before the welder can begin working on it (L) is given by:

c) The average number of hours between when a job is received and when it is completed (Wq) is given as:

d) The average number of hours between when a job is received and when it is completed (W) is given as:
