The two dot plots below compare the forearm lengths of two groups of schoolchildren: Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length? Group X, because no child in the group has a forearm length longer than 12 inches Group X, because four children in the group have the least forearm length of 10 inches Group Y, because a child in the group has the least forearm length of 10 inches Group Y, because six children have a forearm length longer than 12 inches

10. anonymous

A or group X

11. anonymous

B sorry

12. anonymous

Group X, because four children in the group have the least forearm length of 10 inches is answer

13. muscrat123

14. anonymous

yes

15. muscrat123

What is the initial value of the function represented by this table? x y 0 3 1 5 2 7 0 2 3 5

16. anonymous

oh i got it, hope this help: 0 + 3 =3 1+ 4 =5 2+5 =7 3+6=9 5+7=12

17. anonymous

so B

18. anonymous

@Leong

19. muscrat123

why b?

20. anonymous

Because he answer increase by two each time

21. anonymous

the I mean

22. anonymous

yes!

23. anonymous

:0

24. anonymous

next question?

25. anonymous

@muscrat123 look at my answers, you see how i got the results? now look at the number i plus in :)

26. anonymous

:)

27. anonymous

it increase with the results on side y! tadaaaaaaa

28. muscrat123

yay thx

29. anonymous

any more questions?

30. muscrat123

31. anonymous

A

32. anonymous

you chose correct answer :) great

33. muscrat123

Two functions, P and Q, are described as follows: Function P y = 5x + 3 Function Q The slope is 2 and the y-intercept is 4. How much more is the slope of function P than the slope of function Q? 3 5 7 8

@Leong

@_greatmath7 I have to disagree with your answer on "The two dot plots below compare the forearm lengths of two groups of schoolchildren: Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?"

36. muscrat123

yea actually now i think it is d. thx for the catch! @heretohelpalways

37. muscrat123

@Leong @LynFran

41. muscrat123

only 3 more questions!

42. anonymous

gtg I am sorry

43. anonymous

ok 1 more question

44. muscrat123

really fast

45. anonymous

oh and it is D my bad LOL

46. muscrat123

can u help me real fast? @_greatmath7

51. anonymous

I will try But I don't really know functions

There is a 90% chance of rain tomorrow and a 30% chance that the baseball game will be postponed. What is the probability that it will rain tomorrow and the baseball game will be postponed? 3% 6% 27% 60%

53. anonymous

P(A & B) = P(A) * P(B) = .90 * .30 = .27

54. anonymous

So C

55. muscrat123

positive?

56. anonymous

Yes

57. anonymous

I am great at percents and fractions

go to desmond graphing calc and type in both questions and you will get answer

60. anonymous

@muscrat123

61. muscrat123

for the last question i posted? which question?

62. anonymous

the last question you posted

63. muscrat123

how do i use it?

64. anonymous

65. anonymous

or math papa

66. anonymous

use math papa

67. anonymous

you type in y=-3x-2 in algebra calc

Function "P" represents a line, you can determine what geometric body it forms by looking at the variable with the highest exponent, and since both x and y have an exponent of "1" we can conclude that funciton "P" represents a line. A line is all the set of points that form a colineal vector with $$\vec u$$ which is called the "director vector" of the line, and the line is composed by all the points that form a colineal vector with $$\vec u$$ on the axis defined by the direction of the vector and any given point. That+s pretty much all there is to "lines", but what is most important is that lines can be respresented with equation that follow a certain structure, there are a total of 8 forms to express the equation of a line, but you only need to worry about two of them; The general form of the line : $$ax+by+c=0$$ and the "point-slope form": $$y=mx+c$$ You can see that the line represented by the function "P" follows the structure of the second structure: $$y=mx+c$$ where "m" is the slope and "c" is the y-interception. This means, that only observing the equation of the function you can pull out the slope and the y-interception of the function "P". $y=5x+3$ We can see that it follows the structure $$y=mx+c$$ so therefore, we can see that the slope of function "P" is 5 and the y-intercept being "3".

i already figured it out but thanks

sorry I'd really like to help but I'm not practiced enough to be confident that I can teach anyone
