A triangle that has an angle that measures 90 degrees would be a Right Triangle.
Answer:
1.U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
2.U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
Step-by-step explanation:
We are given that
and 
are different sets
1.We have to construct a universe set U and non empty sets A,B and C so that above set in fact the same
Suppose U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}

{2,3,4,5}
={2}
{2,3,4,5}={2}
={2}
={2}
Hence, 
2.We have to construct a universe set U and non empty sets A,B and C so that above sets are in fact different
Suppose U={1,2,3,4}
A={1,2}
B={2,3}
C={4}

={2,3,4}
={1,2}
={1,2}
={1,2}
{2,3,4}={2}
Hence, 
Answer: 14x56=784
Step-by-step explanation:
1.12=1 12/100=1 3/25
or 28/25
This is really simple. We know that landing a 6 is a 2/7 chance that means there is a 5/7 chance of NOT landing a 6 which means that the probability of landing a number that is not 6 would be 5/7. Your answer is D.) 5/7
