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,
81 because 81 is a perfect square and 27 times 3 =81
Answer:
x^2 + x + 2 = 0.
Step-by-step explanation:
The discriminant b^2 - 4ac is < 0 for complex roots.
So we can choose appropriate values for a, b and c.
Let b = 1, a = 1 and c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.
So our equation is:
x^2 + x + 2 = 0.
