Step-by-step explanation:
Let X be the random variable that measures the time waited for a taxi.
If X is exponentially distributed with a mean of 10 minutes,then the probability that you have to wait more than t minutes is
a)
1 hour = 60 minutes, so the probability that you wait longer than one hour is
b)
Due to the “memorylessness” of the exponential distribution, the probability that you have to wait 10 or less minutes after you have already waited for one hour, is the same as the probability that you have to wait 10 or less minutes
c)
We want x so that
P(X>x)=0.1
d)
We want P(X<x)=0.9
Answer:
opposite sides of a parallel are congruent.
Step-by-step explanation:
the symbol between AB and DC stands for "equal to", not parallel. boom roasted. (don't hate me if I'm wrong)
4pi/2pi = x/360
use a proportion
2 radians equals 360 degrees
x = 720 degrees
