Answer:
The answer is (3, 18)
Step-by-step explanation:
This is because if you go to 3 on the x axis and up to 18 on the y axis, you have a point there.

Step-by-step explanation:
Answer:
45.12%
Step-by-step explanation:
We have that l = 50
The probability density function of the exponential distribution is:
(1 / l) * e ^ (x * 1 / l) l> 0
f (X = x) = 0 otherwise
in this case X would come being the probability the road in 30 minutes or less to pick-up the children to go to school, it would come being:
P (X <= 30) = integral from 0 to 30 [1/50 e ^ (x / 50) dx]
It is integral as a result:
P (X <= 30) = (1/50) [e ^ (- x / 50) / (-1/50)]
We evaluate x = 0 up to x = 30
P (X <= 30) = (1/50) [e ^ (- 30/50) / (-1/50)] - (1/50) [e ^ (- 0/50) / (-1 / fifty)]
P (X <= 30) = -0.5488 - (-1)
P (X <= 30) = 0.4512
Therefore the probability is 45.12%

yup mhm oh yeah (its not in simplest form sorry)
