things were not as complicated when I was in middle school.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The two x angles on the right are supplementary which means they add up to 180 degrees
5x + 12 + 7x - 24 = 180
12x - 12 = 180
12x = 192
x = 192/12
x = 18
5x + 12 and y are corresponding angles and are therefore equal
5(18) + 12 = 90 + 12 = 102
Therefore y = 102
 
        
             
        
        
        
I got -19/655 and i know for sure this isnt the correct answer.
        
             
        
        
        
Let X be the number of lightning strikes in a year at the top of particular mountain. 
X follows Poisson distribution with mean μ = 3.8 
We have to find here the probability that in randomly selected year the number of lightning strikes is 0 
The Poisson probability is given by,
P(X=k) = 
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) = 
P(X=0) = 
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
