## Solmyr 3 years ago can someone tell me if im right. In the State of Florida, a redfish must be at least 18 inches long, but no more than 27 inches long for the fish to be considered a keeper. Choose the combined inequality that describes this scenario. 18 x 27 x 18 and x 27 x 18 or x 27 none of the above I got A

1. ParthKohli

Yeah, that's right.

2. Solmyr

ok thank you

3. Solmyr

just wanted to check

4. apple_pi

I can't see any inequality symbols

5. ParthKohli

Just to confirm, is that a \(\le\)?

6. jazy

^^

7. apple_pi

Must be just me

8. Solmyr

yup

9. ParthKohli

Okay then, you are right!

10. Solmyr

you do FLVS Parth?

11. ParthKohli

@apple_pi I have seen many cases like these. @Solmyr Nopers.

12. jazy

I do FLVS:)

13. Solmyr

oh lol i see

14. jazy

Algebra?

15. Solmyr

yup

16. Solmyr

ive got school starting in a week and im trying to finish as fast a i can

17. ParthKohli

Okay then! You guys collaborate while I become a teacher. :P

18. Solmyr

in only at 56% complete

19. Solmyr

ok lol

20. jazy

Had it last year:) Openstudy helpes a lot...but you have to try 2:)

21. Solmyr

no im gonna stick with regular school it seems harder to me on the PC

22. Solmyr

btw did you complete segment 1 completely?

23. jazy

haha:) Parth makes a good teacher... Yeah it doesn't work for everyone:) I'm actually a full time student though...

24. Solmyr

oh :P cool

25. jazy

I finished the whole course during the last school year...Now I started Geometry:) I have to admit that at least math is a lot easier with someone explaining!

26. Solmyr

ya i agree there :]

27. ParthKohli

Never think too hard about Algebra, guys. It just comes and goes ;)

28. jazy

Now i miss all the formulas;( I actually like Algebra though it WAS confusing sometimes.. plus I got kinda lazy last year(bad idea)

29. Solmyr

ya that how i am right now

30. Solmyr

hey do you think u could help me out with some of my algebra assessments??

31. ParthKohli

Algebra is beautiful—I never understand why people worry about it.

32. ParthKohli

Sure, Solmyr. I'd love to(as long as you understand). :)

33. Solmyr

im having allot of difficulty

34. jazy

I still have all my notes:) But Parth is much more up to date on this

35. Solmyr

ok but we can all try :]]

36. Solmyr

hold on

37. ParthKohli

Everything they teach you in Algebra is isolation. lol

38. Solmyr

39. Solmyr

this was my hardest one

40. Solmyr

oh and the honors version of this

41. ParthKohli

I am not good at doing assignments, but you could ask questions one-at-a-time. For example: What is the point-slope form?

42. jazy

Isn't this a mini-project? Do this first....too many words!!: 1. Measure your own height and arm span in inches. You will likely need some help from a parent, guardian, or sibling to get accurate measurements. Record your measurements on the “Data Record” document. You will not need to submit the “Data Record” document as part of this project. Instead, you will use the record to help you complete part two. 2. Measure five additional people you know and record their arm spans and heights in inches. 3. Share the names and measurements of the five people you measured, as well as your own measurements, to your student partner in the class. You may request a method to getting a partner from your teacher. Together you and your partner will have 12 sets of data.

43. Solmyr

yup

44. ParthKohli

We are not allowed to do assignments, but I can explain such mathematical concepts. :|

45. jazy

^^that you can do without help...If you can't measure 5 ppl then make up some of the height vs armsapan)

46. ParthKohli

lol, then you can do that too.

47. Solmyr

ok but how do i use the data record? thing watever it is?

48. Solmyr

would it be easier to save those kind of things last?

49. ParthKohli

Use Microsoft Excel. Haha.

50. jazy

Name Relationship to Student Arm Span in Inches Height in Inches Pat friend 63 63

51. jazy

^^sample

52. jazy

That was the data record i think^^

53. ParthKohli

I can't see what it exactly is. Could a file be uploaded?

54. Solmyr

hold on i can get the data record thing

55. Solmyr
56. Solmyr

see if the link to it works

57. ParthKohli

Let me see.

58. jazy

It works for me but I'm logged in...u see it parth?

59. ParthKohli

Yes, I do.

60. Solmyr

ok good

61. Solmyr

didnt know if it would work for parth

62. ParthKohli

You can use Microsoft Excel for that.

63. ParthKohli

64. Solmyr

ok

65. jazy

Or copy+paste into word and you can still use it.

66. Solmyr

omg that looks complicated lol

67. ParthKohli

Nope. That wouldn't be perfect and convenient.

68. Solmyr

the microsoft excel thing looks complicatesd

69. jazy

Then just select it all and paste it into a word document

70. Solmyr

ok

71. ParthKohli

It's not. I'd make it for you.

72. ParthKohli

But you have to fill the info.. I am just making that format.

73. Solmyr

ok

74. jazy

Meanwhile y don't you start figuring out some heights/armspans...or yours

75. ParthKohli

76. Solmyr

ok btw how many ppl do i have to have??

77. Solmyr

thx parth

78. ParthKohli

6 total people.

79. Solmyr

ok

80. ParthKohli

81. jazy

You and 5 others:)

82. Solmyr

Bob Shirley Robert Peter John MEEE:]]]

83. ParthKohli

Your friend will measure you and five others. lol and you don't measure yourself.

84. jazy

True Parth sorry! Now what's their height/armspan?

85. ParthKohli

Measure yours and just make numbers near to those.

86. jazy

Or make it up if they aren't handy right now:)

87. Solmyr

so bob shirley robert peter john alberto

88. ParthKohli

Like if your height is 150 cm, then you make up numbers near that. 152, 156, 159 etc.

89. Solmyr

im just making random names off the top of my head

90. ParthKohli

lol, nice.

91. jazy

I think it wants the information in inches, correct me if I'm wrong

92. Solmyr

ok sounds simple

93. Solmyr

let me cheeck

94. ParthKohli

Okay, then inches is cool.

95. Solmyr

inches

96. Solmyr

so im like 6 feet

97. Solmyr

so divide 12 and 6

98. ParthKohli

Get short people in the list too, so that it gets legit.

99. Solmyr

srry 12*6

100. jazy

You want a nice, sorted out, and diverse graph:)

101. Solmyr

im 72 inches

102. ParthKohli

Make it 71 or 73 so it gets even more real ;)

103. ParthKohli

And get people with 60 and 65 too.

104. jazy

Here are some numbers from my thing 72 73 62 66 76 76 65 64 68 68 72 73

105. ParthKohli

Cool stuff.

106. jazy

Such as myself...I'm 62 inches lol

107. Solmyr

ok

108. Solmyr

looks legit :PP

109. jazy

Now you have to make a scatter plot with the information.

110. Solmyr

i hate mini-projects lol

111. ParthKohli

Same here :)

112. Solmyr

when this is over what do i put it all on?

113. ParthKohli

That Excel which I submitted.

114. jazy

The excel part is for your own benefit...you dont submit it... Steps 2 & 3 are the actual assignment

115. Solmyr

ok

116. jazy

117. Solmyr

so this part :P

118. jazy

Its not THAT bad...they put so many words that are exhausting!

119. Solmyr

yup

120. jazy
121. jazy

or do it here and take a screenshot: http://www.geogebra.org/webstart/geogebra.html

122. Solmyr

its the line graph sorta right

123. jazy

Scatter plot doesn't have the line - just the points. Make the x-axis the height Make the y-axis the armspan

124. jazy

or vice versa

125. Solmyr

ok

126. Solmyr

so what now

127. jazy

Did you do the scatter plot?

128. Solmyr

i got it but now the saving part

129. Solmyr

what do i save it as

130. Solmyr

131. Solmyr

jazy u there?

132. jazy

Sorry! The graph is really good:) Now you just have to make a line of best fit. Put a line straight through the space where most of the points are.

133. Solmyr

can i us paint

134. Solmyr

135. Solmyr

136. Solmyr

its the second graph

137. jazy

A line of best fit is a straight line going through the whole graph... It doesn't have to go through all of the point. It only represents the majority of the information collected on the graph.

138. Solmyr

can u give me an example of what u mean

139. jazy

140. Solmyr

ok give me a sec

141. Solmyr

142. Solmyr

srry it took me so long my internet malfuntioned

143. Solmyr

is this what u were talking about?

144. jazy

Yes. Now all you have left are the questions: 1. Which two points did you use to draw the line of best fit? 2. Write the equation of the line passing through those two points using the point-slope formula y - y1 = m(x - x1). Show all of your work. Remember to find the slope of the line first. 3. What does the slope of the line represent within the context of your graph? 4. Using the equation that you found in question 2, approximately how tall is a person whose arm span is 66 inches? 5. According to your line of best fit, what is the arm span of a 74-inch-tall person?

145. jazy

Really? My internet glitched too:/

146. Solmyr

what does 1. mean????

147. Solmyr

it might be because we have so much stuff

148. Solmyr

if you want i can reopen a question

149. jazy

Woops sorry! When you draw a line of best fit you are supposed to guide yourself with two points on the graph.

150. jazy

151. Solmyr

its cool

152. Solmyr

well would my points be 64 and 73
