Express the set of real numbers between but not including 2 and 7 as follows. (a) In set-builder notation:_________ (b) In interval notation:_________-

Tell whether each number is an element of  (a natural number),  (an integer),  (a rational number),  (an irrational number), or  (a real number). Since these sets are not all disjoint, you may need to list more than one set for each answer. (Select all that apply.) (a)    15   (b)    5.78   (c)    1.3636363636...   (d)       3   (e)    ?   (f)     0.0017   (g)       16   (h)       100,000   (i)     1 8
