Since

, we know that

follows a Poisson distribution with parameter

.
Now assuming

denote the mean and standard deviation of

, respectively, then we know right away that

and

.
So,
Answer:
4n^2 + 22n
Step-by-step explanation:
10(n^2+n) -6 (n^2 - 2)
10n^2 + 10n - 6n^2 + 12
4n^2 + 22n
Answer:
AB = 
Step-by-step explanation:
calculate the distance using the distance formula
d = 
with (x₁, y₁ ) = B (3, 2 ) and (x₂, y₂ ) = A (7, 4 )
AB = 
= 
= 
= 
≈ 4.47 ( to 2 dec. places )
