Answer:
3 ways
Step-by-step explanation:
How many different ways can you place 4 identical marbles in three jars shown below? Note: Every marble needs to be in one of the jars, but not every jar needs to have a marble in it.
We solve using combination
n-1 C r-1 = nCr = n!/r! (n - r)!
n = 4 identical marbles
r = 3 jars
Hence:
4 - 1 C 3 - 1 = 3C2
= 3!/2! (3 - 2)!
= 3 ways
Answer:
D
Step-by-step explanation:
Answer:
-1/2
Step-by-step explanation:
The equation for slope is (y2-y1)/(x2-x1).
Plug in the values given in the problem
(11-7)/((-2)-6)
Then simplify
4/(-8)=-1/2
