For each of these pairs of sets, determine whether the first is a subset of the second, the second is a subset of the first, or neither is a subset of the other. a) the set of airline flights from newyork to new delhi, the set of nonstop airline flights from new york to new delhi. b) the set of people who speak english, the set of people who speak chinese. c) the set of flying squirrels, the set of living creatures that can fly.

a) The second is a subset of the first.

b) Neither

c) The first is a subset of the second.

Step-by-step explanation:

A set B is a subset of another one A if all the elements from the set B are part of the set A.

a) the set of airline flights from NewYork to New Delhi, the set of nonstop airline flights from New York to New Delhi: The second set is a subset of the first. It is obvious that all the nonstop airline flights from NY to ND are part of the airline flights from NY to ND.

b) the set of people who speak English, the set of people who speak Chinese. Neither. The people who speak english do not necessarily speak Chinese or vice versa.

c) the set of flying squirrels, the set of living creatures that can fly: The first set is a subset of the second. All flying squirrels are creatures that can fly, therefore, they all belong to the set of flying creatures.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

it has to have an angle of 90 degrees
