Answer:
The first and second one
Step-by-step explanation:
Had the problem an it showed that those two were correct hope I help
Use the Pythagorean theorem A^2 + B^2 = C^2. C is the slant length. Hope this helps.
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,
Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3
The answer is 832,719.
842,719 - 10,000 = 832,719
