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 can't see any inequality symbols

- ParthKohli

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

- anonymous

^^

- anonymous

Must be just me

- anonymous

yup

- ParthKohli

Okay then, you are right!

- anonymous

you do FLVS Parth?

- ParthKohli

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

- anonymous

I do FLVS:)

- anonymous

oh lol i see

- anonymous

Algebra?

- anonymous

yup

- anonymous

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

- ParthKohli

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

- anonymous

in only at 56% complete

- anonymous

ok lol

- anonymous

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

- anonymous

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

- anonymous

btw did you complete segment 1 completely?

- anonymous

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

- anonymous

oh :P cool

- anonymous

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!

- anonymous

ya i agree there :]

- ParthKohli

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

- anonymous

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

- anonymous

ya that how i am right now

- anonymous

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

- ParthKohli

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

- ParthKohli

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

- anonymous

im having allot of difficulty

- anonymous

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

- anonymous

ok but we can all try :]]

- anonymous

hold on

- ParthKohli

Everything they teach you in Algebra is isolation. lol

04.08 Scatter plots and lines of best fit project.
Step One: Measurements
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.
Step Two: Creating Your Scatter Plot
Using GeoGebra or a graphing software of your choice, draw your scatter plot and the line you think represents the line of best fit. Note: Directions for downloading and using GeoGebra can be found in the "Course Information area.”
1. Both you and your partner need to create a scatter plot of the 12 data points you both collected.
2. Draw the line that you feel best fits the data.
3. Copy and paste your scatter plot into a word processing document.
4. Share and discuss your scatter plot and the line of best fit with your partner. If your scatter plots or lines of best fit are different, discuss reasons why they might be different.
Step Three: The Line of Best Fit
Include your scatter plot and the answers to the following questions in your word processing document and submit to your instructor. Be sure to review how to save your files before getting started. You and your partner are free to discuss this part of the project. However, each of you will be responsible for submitting your own attachment of this file.
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?

- anonymous

this was my hardest one

- anonymous

oh and the honors version of this

- 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?

- anonymous

Isn't this a mini-project?
Do this first....too many words!!:

- anonymous

yup

- ParthKohli

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

- anonymous

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

- ParthKohli

lol, then you can do that too.

- anonymous

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

- anonymous

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

- ParthKohli

Use Microsoft Excel. Haha.

- anonymous

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

- anonymous

^^sample

- anonymous

That was the data record i think^^

- ParthKohli

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

- anonymous

hold on i can get the data record thing

- anonymous

http://learn.flvs.net/webdav/educator_algebra1_v14/gendocs/data_record.htm

- anonymous

see if the link to it works

- ParthKohli

Let me see.

- anonymous

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

- ParthKohli

Yes, I do.

- anonymous

ok good

- anonymous

didnt know if it would work for parth

- ParthKohli

You can use Microsoft Excel for that.

- ParthKohli

Or any other spreadsheet.

- anonymous

ok

- anonymous

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

- anonymous

omg that looks complicated lol

- ParthKohli

Nope. That wouldn't be perfect and convenient.

- anonymous

the microsoft excel thing looks complicatesd

- anonymous

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

- anonymous

ok

- ParthKohli

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

- ParthKohli

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

- anonymous

ok

- anonymous

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

- ParthKohli

##### 1 Attachment

- anonymous

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

- anonymous

thx parth

- ParthKohli

6 total people.

- anonymous

ok

- ParthKohli

Your friend and five others.

- anonymous

You and 5 others:)

- anonymous

Bob
Shirley
Robert
Peter
John
MEEE:]]]

- ParthKohli

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

- anonymous

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

- ParthKohli

Measure yours and just make numbers near to those.

- anonymous

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

- anonymous

so
bob
shirley
robert
peter
john
alberto

- ParthKohli

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

- anonymous

im just making random names off the top of my head

- ParthKohli

lol, nice.

- anonymous

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

- anonymous

ok sounds simple

- anonymous

let me cheeck

- ParthKohli

Okay, then inches is cool.

- anonymous

inches

- anonymous

so im like 6 feet

- anonymous

so divide 12 and 6

- ParthKohli

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

- anonymous

srry 12*6

- anonymous

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

- anonymous

im 72 inches

- ParthKohli

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

- ParthKohli

And get people with 60 and 65 too.

- anonymous

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

- ParthKohli

Cool stuff.

- anonymous

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

- anonymous

ok

- anonymous

looks legit :PP

- anonymous

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

- anonymous

i hate mini-projects lol

- ParthKohli

Same here :)

- anonymous

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

- ParthKohli

That Excel which I submitted.

- anonymous

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

- anonymous

ok

so this part :P

- anonymous

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

- anonymous

yup

- anonymous

scatter plot:
http://nces.ed.gov/nceskids/createagraph/default.aspx?ID=963c1048b3e14cba93b9311bb7de7687

- anonymous

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

- anonymous

its the line graph sorta right

- anonymous

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

- anonymous

or vice versa

- anonymous

ok

- anonymous

so what now

- anonymous

Did you do the scatter plot?

- anonymous

i got it but now the saving part

- anonymous

what do i save it as

- anonymous

##### 1 Attachment

- anonymous

jazy u there?

- anonymous

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.

- anonymous

can i us paint

- anonymous

its the second graph

- anonymous

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.

- anonymous

can u give me an example of what u mean

- anonymous

Heres a picture from google:

ok give me a sec

- anonymous

srry it took me so long my internet malfuntioned

- anonymous

is this what u were talking about?

- anonymous

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?

- anonymous

Really? My internet glitched too:/

- anonymous

what does 1. mean????

- anonymous

it might be because we have so much stuff

- anonymous

if you want i can reopen a question

- anonymous

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

- anonymous

my bad

- anonymous

its cool

- anonymous

well would my points be 64 and 73
