12+12+12 =36
but
10+12+14=36
10 could be the smallest consecutive even number
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:
X=7.9
Y=7.9
Step-by-step explanation:
We have that x=y
And form Pythagoras theorem we have
So x = y = 7.9
Answer:
Step-by-step explanation:
5x + 8y = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
5x + 8y + -8y = 24 + -8y
Combine like terms: 8y + -8y = 0
5x + 0 = 24 + -8y
5x = 24 + -8y
Divide each side by '5'.
x = 4.8 + -1.6y
Simplifying
x = 4.8 + -1.6y
