julianmiddleton 3 years ago If C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} and D = {numbers divisible by 2 from 1 to 12}, what is C ∩ D

1. julianmiddleton

2. Solmyr

FLVS?

3. julianmiddleton

yes im just confused

4. Solmyr

ok

5. Solmyr

well the upside down U means Intersection whichs means if there is more then one of the same numberthat is your answer for example

6. julianmiddleton

so would it be 2,4,6,8,10,12?

7. Solmyr

yup

8. julianmiddleton

i have more if your willing you help but thanks :) letme know if you still want to help :)

9. Solmyr

sure

10. julianmiddleton

Choose the relation with a range of {−4, 0, 1}.

11. Solmyr

btw is this a test????

12. Solmyr

if it is put the module number with the question

13. julianmiddleton

3.05] Choose the relation with a range of {−4, 0, 1}.

14. Solmyr

ok

15. julianmiddleton

R = {(−4, −2), (0, 0), (1, 3), (−4, −2), (1, 3)} R = {(3, 1), (0, 0), (−2, −4), (3, 1), (−2, −4)} R = {(3, 2), (1, 8), (1, 2), (0, −5), (−4, 4), (−2, 5)} R = {(2, 3), (8, 1), (2, 1), (−5, 0), (4, −4), (5, −2)}

16. julianmiddleton

17. Solmyr

ummm is this module three pretest or the regular test?

18. julianmiddleton

regular test

19. julianmiddleton

btw thank you

20. Solmyr

ok

21. Solmyr

22. julianmiddleton

me to [3.02] The set S represents the elements present in sugar. S = {carbon, hydrogen, oxygen} The set C represents the elements present in carbon dioxide gas. C = {carbon, oxygen} How many elements are in the set S ∩ C?

23. Solmyr

whats the choices

24. julianmiddleton

i know carbon and oxy are a set but does that make 1 set

25. julianmiddleton

1 2 3 5

26. julianmiddleton

i say 1

27. Solmyr

give me a sec i know this one i got a 96 on the test :P

28. Solmyr

its 1

29. julianmiddleton

oh nice!

3.05] Which of the following does not represent a function? x 1 3 5 7 y 7 11 15 11 x −4 −2 0 2 y 3 −1 −5 −9 x −4 −3 −2 −1 y −32 −18 −8 −2 x −3 2 6 2 y 0 1 5 4

31. julianmiddleton

thatswhat i got @Solmyr

32. Solmyr

well when answering these kind of questions we look at the x-value

33. Solmyr

34. julianmiddleton

ok x is 1 3 5 7

35. Solmyr

u have to look at the x-value if there is more then one of the same number then to relation is not a function.

36. julianmiddleton

i got d actually

37. Solmyr

correct

38. Solmyr

because there are two 2's in the x-value

39. julianmiddleton

yeah your actually helping me alot then theres this sthough

[3.03] At an auto show, a car dealer asked the first 10 visitors their ages and the kinds of cars they own. The Venn diagram shows the details. Based on the diagram, which of the following represents the ages of car owners in the set (~P ∩ Q) ∪ (P ∩ R)? {32, 48, 64} {38, 42, 53} {32, 42, 53, 64} {32, 38, 42, 53, 64}

41. julianmiddleton

theres and attachment we dont have to do this one if you dont want to

42. Solmyr

i might be able explain thiis one but

43. Solmyr

srry idk this was the only one i got rong :PP

44. julianmiddleton

ahahah its fine :) Choose the correct statement about the given Venn Diagram. A total of 25 people were surveyed. A total of 3 people surveyed like cookies. A total of 10 people surveyed like cake and cookies. A total of 13 people surveyed like cake.

ya its c

50. Solmyr

possible combinations?

3.05] Carla is making ramps of different lengths. The ramps are made with rectangular and square wooden boards. The relationship between the length of the ramp in feet, f(n), and the number of square boards used, n, is represented by the function below. f(n) = 4n + 5 , where 20 ≤ n ≤ 30 Which statement is correct about the range of the length of the ramp for the given domain? It varies from 20 to 30. It varies from 20 to 125. It varies from 80 to 120. It varies from 85 to 125.
