Answer:
if i'm doing it right then sin p, but i'm not entirely sure...sorry
Step-by-step explanation:
Answer with explanation:
- An integer is a whole number that can be positive, negative, or zero. For example ...-3,-2,-1,0,1,2,3....
- Here, positive value indicates gain or above something where as negative value indicates loss or below something.
If the change in the value of his favorite card is $-7, that simply indicates that he is having a loss of $-7 that can be understand as the value of his this years card must be smaller than the last year card.
Hence, the best describes the meaning of integer:
"he is having a loss of $-7"
I know you said "without making any assumptions," but this one is pretty important. Assuming you mean are shape/rate parameters (as opposed to shape/scale), the PDF of is
if , and 0 otherwise.
The MGF of is given by
Note that the integral converges only when .
Define
Integrate by parts, with
so that
Note that
By substitution, we have
and so on, down to
The integral of interest then evaluates to
so the MGF is
The first moment/expectation is given by the first derivative of at .
Variance is defined by
The second moment is given by the second derivative of the MGF at .
Then the variance is
Note that the power series expansion of the MGF is rather easy to find. Its Maclaurin series is
where is the -derivative of the MGF evaluated at . This is also the -th moment of .
Recall that for ,
By differentiating both sides 7 times, we get
Then the -th moment of is
and we obtain the same results as before,
and the same variance follows.
This is how it would look on a graph.
Answer:
-64/5
Step-by-step explanation:
Basically, the word "quotient" means the answer to a division problem. Therefore, its a division problem, so you have to work backwards with multiplication. -8 times a number is 5/8, so the other number is going to be negative.
The number is -64/5
