Due Monday, May 4
section 2.1
problems:
  • 1
  • 2 - All ratios written as fractions must be in most reduced form.
  • 5a, 5b, 5c, 5d
  • 6 - When writing a ratio you must pay attention to the units. For example: if the units are g/Kg=g/Kg that is OK. However, you can also write this as g/g=Kg/Kg because the units cancel each other so both sides of the ratio are unit-less, which is the same (note: the numerator and denominator must represent the same thing). Problem 6c, you will need to change some units to make this problem work.
  • 7a, 7b - Remember that every proportion can be written in 4 different ways.
  • 8
  • 9
  • 10

  • Enter the following coordinate points in L1 and L2. There should be 51 entries in L1, same for L2.
  • Turn on statplot, set window and graph to see the "secret message".
  • Plot some of the points manually to understand how I did this.
  • Make your own "secret code". Note: curved letters like "C" take a lot of points! First draw the letters on graph paper. Determine the coordinates and the order. Then enter in statplot and see if it worked!
