Answer:
B
Step-by-step explanation:
When solving multiple choice problems, a reasonable strategy is to look for ways to identify one answer as good, or other answers as bad.
Here, all of the constant vectors in the equations are different, so we can decide the answer based on that.
The only equation with the correct constant vector is choice B.
_____
The constants in the equations are -4, 1, 9 — the values to the right of the equal sign.
Answer:
Step-by-step explanation:
Since argument is the value of independent variable x .
Here y= 1 when x = 0.
Taking integration on both sides , we get
Put y=1 and x=0 [given] , then
Hence, the function will be
Recall that for a random variable
following a Bernoulli distribution
, we have the moment-generating function (MGF)
and also recall that the MGF of a sum of i.i.d. random variables is the product of the MGFs of each distribution:
So for a sum of Bernoulli-distributed i.i.d. random variables
, we have
which is the MGF of the binomial distribution
. (Indeed, the Bernoulli distribution is identical to the binomial distribution when
.)
Also, if you are 15 (and you don't look like it), then why do you need help adding polynomials, one of the most basic algebraic concepts?
