Factoring:
FOIL (first, outer, inner, last) method
(a+b)(c+d) = 0
ac+ad+bc+bd = 0
Zeros:
(x+a)(x+b) = 0
x+a = 0, x= 0-a
x+b = 0, x= 0-b
Answer:
0
Step-by-step explanation:
given that we roll a fair die repeatedly until we see the number four appear and then we stop.
the number 4 can appear either in I throw, or II throw or .... indefinitely
So X = the no of throws can be from 1 to infinity
This is a discrete distribution countable.
Sample space= {1,2,.....}
b) Prob ( 4 never appears) = Prob (any other number appears in all throws)
= 
where n is the number of throws
As n tends to infinity, this becomes 0 because 5/6 is less than 1.
Hence this probability is approximately 0
Or definitely 4 will appear atleast once.
Answer:
The domain for graph 1 is all real numbers, the range is y >= 0.
The domain for graph 2 is x >= 0, the range is y >= 0
Step-by-step explanation:
Graph 1: The x values are infinite for the graph, the y values will always be above zero and continue to be infinite.
Graph 2: The x values start at 0 and go to the right for infinity, the y values start at 0 and continue to infinity.
