## tictac4456 3 years ago N is the set of real numbers that are factors of 20.

1. ucreategames

whats the question?

2. tictac4456

what numbers go in 20

3. ucreategames

are you able to copy the exact problem, so i can see wat ur tlkin about?

4. tictac4456

ok

5. tictac4456

i cant

6. CliffSedge

There are an infinite quantity of real numbers that are factors of 20.

7. tictac4456

like?

8. ucreategames

4 5 2 10 1 20

9. CliffSedge

Are you sure you are looking for Real numbers and not just Natural numbers? N is more commonly a symbol for Natural numbers. For example, 10√2 and √2 are two real numbers that are factors of 20.

10. ucreategames

those are just positive whole numbers

11. ucreategames

12. tictac4456

so what should the answer be

13. tictac4456

yes

14. ucreategames

15. tictac4456

A.{2, 4, 5, 10} B.{2, 4, 6, 8, 10, 12, 14, 16, 18, 20} C.{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20} D.{1, 2, 4, 5, 10, 20}

16. CliffSedge

2√5 is also a real number factor of 20... Like I said, there are an infinite amount. If you restrict the set to whole numbers, then it's different.

17. ucreategames

d

18. tictac4456

thank uuuuu

19. ucreategames

a contains some of the answers but d contains all compared to the rest

20. ucreategames

np

21. CliffSedge

See how much easier it is when you post then entire question, including the answer choices? :-)

22. ucreategames

cliffsedge

23. tictac4456

Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set, and P = {1, 3, 5, 7}. What is P

24. ucreategames

put that in a different question close this one

25. tictac4456

ok
