Answer:
16
Step-by-step explanation:
To start off this problem, we are given that the line AB is equal to the line CD. In addition to that, we are given that the line EF equally intersects line AB and line CD. This provides us proof that angle AGH is equivalent to angle DHG. From this information, we can solve this problem relatively easily.
Lets work with this equation:
Next, divide 80 by 5.
This means that x is equal to 16.
Answer:
1.3125
Step-by-step explanation:
Given that our random variable follows a Poisson distribution
Evaluate the formula at
#since
The mean and variance of the Poisson distributed random variable is equal to :
#By property variance:
The expectation is 1.3125
