Also label axes, provide a title, space correctly, and use the most appropriate graph. Then answer the questions about each graph. type of

Explanation / Answer

1) 3200 mm/ 10200 mm

= 0.3137

= 313.7 mm

2800 um x 30000 um

= 84000000 × 10^-12

= 84 × 10^-6

= 84 micro mm

2) 10 um = 0.01 mm

230 cm = 2300000 um

0.004 ug = 0.000004 mg

1.2 x 10^4 ml = 12 L

4.5 mg = 0.0045 g

230050 cm = 2300500 mm

2) Graph:

1) Independent variable is changed in an experiment. It is also known as control variable. Here, size of the pill is independent variable. It goes in x axis.

2) Dependent variable is the variable of interest. It goes in y axis. Here, amount of calcium carbonate is dependent variable.

3) Scatter plot is used because it shows relation between two quantitative variables.

4) There appears to be no relation either positive or negative between size of the pill or the amount of calcium carbonate.
