Answer:
Step-by-step explanation:
50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter
so both are equal.
The answer is 1/5, or 0.2, because if you're always putting the slip back in, then there will always by 5 slips to choose from, therefore making the probability 1 out of 5. I hope this helps!
Answer = -20
-4-5+4+(-5)-4-5+4+(-5) =-20
Let
be any integer. Then
In other words:
(1) If
is a multiple of 4, then
.
(2) If dividing
by 4 leaves a remainder of 1, then
, since
for some integer
, and from (1) we know that
(because, obviously,
is a multiple of 4).
(3) If instead you get a remainder of 2, then
. This follows from (1) as well.
.
(4) Finally, if you get a remainder of 3, then
.
