The answer relies on whether the balls are different or not.
If they are not, which is almost certainly what is intended.
If they are, the perceptive is a bit different. Your
expression gives the likelihood that a particular set of j balls
goes into the last urn and the other n−j balls into the other urns.
But there are (nj) different possible sets of j balls, and each of
them the same probability of being the last insides of the last urn, so the
total probability of completing up with exactly j balls in the last
urn is if the balls are different.

No, it's not possible for the sides of a triangle to have those lengths.
According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

This inequality satisfies the triangle inequality theorem.

This also satisfies the theorem.

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.
The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
Answer:
80
Step-by-step explanation:
-4f(x)=-12x+44
-4f(-3)=36+44=80
Answer:
$42
Step-by-step explanation:
Given that,
Galore Super Store buys the latest video game at a wholesale price of $30.00.
The markup rate at Game's Galore Super Store is 40%.
We need to find the price from the store. It can be calculated as follows :

Hence, we will pay $42.
