Q12. Fill in the missing element of B such that A = B.
A = {7, 19, g, #, 2, 4, &, f, 14, 1, k}
B = {#, 1, 7, __, k, 2, f, 19, g, 4, &}
Q13. Let A = {y ∈ Z : 4 <y ≤ 28 and y is even}. What is |A|?
Q14D. Define the sets A, B, C, and D as follows:
- A = {-3, 1, 6, 7, 10}
- B = {-10, -5, 1, 4, 6}
- C = {x ∈ Z: x is odd}
- D = {x ∈ Z: x is positive}
-
Find A ∩ D.
*Express the set using roster notation and with values ordered smallest to largest, such as {-10, -3, 1, 6} (braces and commas are required; a space after each comma is also required).
Q14C. Define the sets A, B, C, and D as follows:
- A = {-3, 1, 6, 7, 10}
- B = {-10, -5, 1, 4, 6}
- C = {x ∈ Z: x is odd}
- D = {x ∈ Z: x is positive}
Find B ∩ C.
*Express the set using roster notation and with values ordered smallest to largest, such as {-10, -3, 1, 6} (braces and commas are required; a space after each comma is also required).
A = {y ∈ Z : 2 < y ≤ 9 and y is odd} - B = {1, 4, 6}
- C = {y ∈ Z : y ≤ 10, y is even, and y is positive}
- D = {y ∈ Z : y ≤ 7 and y is positive}
- E = {-3, -1, 0, 5}
-
Find C ∪ D.

- D = {y ∈ Z : y ≤ 7 and y is positive}
- E = {-3, -1, 0, 5}
-
Find D ∪ E.
