Answer:
True.
Step-by-step explanation:
We are given that two disjoint sets
We have to find that the statement number of outcomes of disjoint set is equal to sum of number of outcomes for each event
If sets are disjoint then
Let n(A)=x
n(B)=y
We know that
Hence, to find the number of outcomes of disjoints set ,add the number of outcomes for each event.
Therefore, the statement is true.
Answer:
yes I belive it is like that
Step-by-step explanation:
Answer: 9/7 or 1.3 (rounded)
reasoning: -2 + 7x/9 = -1
7x/9 = 1
7x = 9
x = 9/7, or 1.3 (assuming they allow you to round to the nearest tenth)
60/25 = 12/Y
cross multiply and divide
25 x 12 = 300
300 / 60 = 5
Y = 5 boxes
Answer:
x= -1, y = -1
Step-by-step explanation:
-16x +24y = -8
16x -8y = -8
16y = -16
y=-1
16x = -16
x = -1
