This simplified is 126x so that is equivalent to this expression
Y = 2x/x-7
x = 2y/y-7
xy - 7x = 2y
-7x = 2y - xy
-7x = y(2-x)
y = -7x / 2-x
y = 7x / x-2
f-¹(x) = 7x / x-2
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: $33.00
Step-by-step explanation:
Given
Mr. Claussen needs 15 Pounds of ground beef
It is stated that 2 pounds of beef cost $4.40
Using unitary method
1 Pound cost
For 15 pounds it is
Thus, he has to spend $33 for 15 pound meat
