5 .For part III, Average was needed to be found after Find the Mass/A of each all 5 disk. To do that Add all the values in Table 3 and divide them by 5. 6 .For Part III, Percent difference between the average value and the slope of the derivative diameter graph was found by doing this: ((slope of the derivative vs. diameter graph- average)/slope of derivative vs. diameter graph)*100 =67.9% VII. Analysis Questions/Answers 1. The Slope in Part I represents π 2.
10g , 78°C. When your independent variable is continuous, you need to draw a line graph. A Categoric variable is one that is described in words (or categories! ), e.g. species of plants, colours, metals tested, etc.
The purpose of this Landscape Analysis Project is to explore and analyze a landscape. Three dimensions of the landscape will be investigated, namely the physical landscape, the political/economic landscape and the cultural landscape. This study is organized using these three dimensions; however understanding the linkages and connections between dimensions is critical to understanding the landscape. 1) Find at least two definitions of landscape and cite the source: My first definition is a section or expanse of rural scenery, usually extensive, that can be seen from a single viewpoint (Websters Dictionary, 2011). The second definition states a landscape is an expanse of scenery that can be seen in a single view (Miller, 1995) 2) In
