So you need to add 6n with +2 then 5-7
Answer:
b. 0.25
c. 0.05
d. 0.05
e. 0.25
Step-by-step explanation:
if the waiting time x follows a uniformly distribution from zero to 20, the probability that a passenger waits exactly x minutes P(x) can be calculated as:

Where a and b are the limits of the distribution and x is a value between a and b. Additionally the probability that a passenger waits x minutes or less P(X<x) is equal to:

Then, the probability that a randomly selected passenger will wait:
b. Between 5 and 10 minutes.

c. Exactly 7.5922 minutes

d. Exactly 5 minutes

e. Between 15 and 25 minutes, taking into account that 25 is bigger than 20, the probability that a passenger will wait between 15 and 25 minutes is equal to the probability that a passenger will wait between 15 and 20 minutes. So:

5(x-2)=7+x would be your equation
to sum it up, the Abbasid Empire fell down due to these reasons:
- Power struggles, and an unorganized method for succession.
- Invasions (alot of them)
- Interior struggles with farmers and military.
- ncompetent leaders controlled by other forces.
The 'Abbasid caliphate in the fourth/tenth century suffered from a sharp economic decline. This was the result of several factors, mainly civil wars, the Zanj and Qarmatian revolts, political interference by the Turkish and Daylamite soldiers, military iqt\a>' and the activity of the 'ayya>ru>n.
