a. The events are mutually exclusive, so
b. For the same reason,
Another way to see this is to use the result from part (a), and the inclusion/exclusion principle:
and the right side reduces to 0.
c. Same as (b),
d. Same as (b),
We can also use the distributivity rule for unions and intersections to write
e. If the 
is the complement of 
, then by DeMorgan's law,
2x - 11
-9 + x
equate the equations
2x - 11 = -9 + x
bring like terms to one side
2x - 11 = -9 + x
- x +11 +11 - x
-11 and +11 cancels out
+x and -x cancels out
2x - x = 11 - 9
x = 2
Because you cannot add the two numbers you must find a common denominator for 16 and 20. This answer is 4. The greatest number of group members possible is 4.
Answer:
the answer is the Scientific notation of 1×10^13
Answer:
A 6 units up
Translation rule
Y rule
+= up
-= down
X rule
+= right
-=left
Reflection rule
Reflection over x axis
Y that was once a positive number, is flipped to a negative
example
6,2 reflected over the x axis.
2=-2
Y axis rule example
-2,7 reflected over the y axis
-2=2
Step-by-step explanation:
If it ever says (example,example) like flipped over the x, it will change the y.
Same for a flip over the y, it will change the x
