Question 1208299: 1 Write the following in set notation:
(a) The set of all real numbers greater than 27.
(b) The set of all real numbers greater than 8 but less than 73.
2 Given the sets S_{1} = \langle2, 4, 6\rangle following statements are true? S_{2} = \langle7, 2, 6\rangle S_{3} = \langle4, 2, 6\rangle and S_{4} = \langle2, 4\rangle which of the
(a) S_{1} = S_{2}
(d) 3 \notin S_{2} deg
(g) S_{1} supset S 4
(b) S_{1} = R
(e) 4 \notin S_{4}
(h) emptyset subset S ?
(c) 5 \in S_{2}
(f) S_{4} subset R
(1) S 3 supset \langle1, 2\rangle
3 Referring to the four sets given in the preceding problem, find:
(a) S_{1} cup S 2
(c) S_{2} cap S 3
(e) S_{4} cap S 2 cap S 1
(b) S_{1} cup S 3
(d) S_{2} cap S 4
(f) S_{1} cup S 1 cup S 4

No fair dumping a whole bunch of problems on us like that!
Here's the first one.  Maybe someone else will do some others.

1 Write the following in set notation:
(a) The set of all real numbers greater than 27.
{x|x ε R, x > 27}

(b) The set of all real numbers greater than 8 but less than 73.
[Note: "it is greater than 8" is the same as saying "8 is less than it"]: 

{x|x ε R, 8 < x < 73}
