Archimedes Principle Experiment – Part 3 Given the data set provided to you, complete the following problems. 1. Create a scaBerplot of your data on graph paper. Make sure to label the x and y axis with the correct quanFty and units. Make sure to use an appropriate scale. Create a Ftle for your scaBerplot 2. Create a 3 Column Process Chart. Input your data into the Domain and Range Columns and use the example 3CPC to complete the middle Process Column. 3. What is the equaFon (funcFon rule) governing this relaFonship? 4. Add 6 units to you largest domain value and determine the corresponding range value. JusFfy your answer verbally, by table, by graph, or algebraically. 5. Add 3.7 to you largest range value and determine the corresponding domain value. JusFfy your answer verbally, by table, by graph, or algebraically. 6. Does your data depict a conFnuous relaFonship or a discrete relaFonship? JusFfy your answer. 7. Does your data represent an funcFonal relaFonship? JusFfy your answer. 8. Describe the correlaFon depicted by your data. Explain your answer. 9. Determine the Domain and Range of your data. Express the informaFon in the correct notaFon. # texts month miles hour Discrete: Can you send 0.5 or 0.365 of text message? No only whole texts. A graph of isolated points. ConFnuous: a situaFon that can be expressed as a decimal or fracFon. It is possible to travel at a speed of 64.24564 mph.

Archimedes  Principle  Experiment  –  Part  3    Given  the  data  set  provided  to  you,  complete  the  following    problems.              1.  Create  a  scaBerplot  of  your  data  on  graph  paper.    Make  sure  to  label  the  x  and  y  axis  with  the  correct  quanFty  and  units.    Make  sure  to  use  an  appropriate  scale.  Create  a  Ftle  for  your  scaBerplot    2.  Create  a  3  Column  Process  Chart.    Input  your  data  into  the  Domain  and  Range  Columns  and  use  the  example  3CPC  to  complete  the  middle  Process  Column.    3.  What  is  the  equaFon  (funcFon  rule)  governing  this  relaFonship?        4.  Add  6  units  to  you  largest  domain  value  and  determine  the  corresponding  range  value.    JusFfy  your  answer  verbally,  by  table,  by  graph,  or  algebraically.    5.  Add  3.7  to  you  largest  range  value  and  determine  the  corresponding  domain  value.  JusFfy  your  answer  verbally,  by  table,  by  graph,  or  algebraically.    6.  Does  your  data  depict  a  conFnuous  relaFonship  or  a  discrete  relaFonship?    JusFfy  your  answer.            7.  Does  your  data  represent  an  funcFonal  relaFonship?    JusFfy  your  answer.    8.  Describe  the  correlaFon  depicted  by  your  data.    Explain  your  answer.    9.  Determine  the  Domain  and  Range  of  your  data.    Express  the  informaFon  in  the  correct  notaFon.

Finding  b:  1.    2.    3.  

1.23(0)+ b = 3.7

0+ b = 3.7

b = 3.7

Using  a  3  Column  Process  Chart:    1.  Input  your  Domain  and  Range  Values  2.  Calculate  the  change  in  x  values  and  and  the  change  

in  y  values  3.  Determine  Rate  of  Change  by  placing                  change  in  y/change  in  x  4.  Input  Slope  and  Domain  values  into  Process  Column  5.  Find  the  y-­‐intercept  

Set  up  equaFon  to  solve  for  b    with  (x0,y0)    MulFply  and  simplify      SoluFon;  value  of  the  y-­‐intercept    *A  similar  process  can  be  used  for  any  ordered  pair    (xn,yn)
