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.
Since line AB and line CD are parallel, and line EF is perpendicular to line CD, line EF is also perpendicular to line AB.
Answer:
Line AB and line EF are perpendicular.

Answer:
4.3
Step-by-step explanation:
Since her scale only shows tenths, the weights of the packets will be
Packet A - 4.4
Packet B - 4.3
Packet C - 4.4
Packet D - 4.4 since 9 rounds 3 up to 4
Answer:
First, distribute the 4.
2x times 4 = 8x
3x times 4 = 12x
then add/ combine like terms.
8x + 12x = 20x
Step-by-step explanation:
The answer is D . Because 20+20=40 10+10=20 so 40+20=60
