Arithmetic mean

From the percent difference I can conclude that neither surface area, surface texture, nor mass of block has that big of an impacted on the friction. The higher the percent difference is the more effect friction would have on it, with the lower percent difference says it wouldn’t affect friction. For surface area testing side A against side B on smooth sliding for percent difference was60.78%, over half (50%) but not by much. For weight off sandpaper the difference was only 40.00%, where on…

will do a small recap of the central tendency and then I will illustrate what a systematic error (bias) in action. The central tendency can be measured in three ways: mean, median, mode. Mean is the more precise, then median and lastly mode. In a normal condition, all three of them are equal; however, in the presence of outliner the mean is more distorted than the median. So how do we avoid distortion in a business? Or what do you think the single most…

%\addcontentsline{toc}{section}{Activity 1.16} \section*{Activity 1.16} \begin{enumerate} \item The graphs are different because of scaling, and the bar chart A start at zero while the bar chart B start at 25. \item Yes, the graphs tell the same story, even though the scale is different, he used the scale of 20 units in Bar chart A and 5 units in Bar chart B. \item Jairos should use Bar chart B because it represents the information clearly and accurately, In Bar chart A is not easy to tell…

1. What did the experiment show about how prey are selected by predators? A - Prey are selected based on accessibility, meaning ones that are the most easy to find and catch are the most susceptible. In this experiment, the moths that blended into the background were chosen less frequently than the ones that did not blend in. An example is that the white moths on a white background were chosen at a much lesser rate than newspaper moths. Three white moths and 11 newspaper moths in total (trial 1…

partial product is determined by next three bits i.e. multiply by 2. Multiply by 2 means the multiplicand value has to shift left one bit. So, the second partial product is 001000100. Similarly the third partial product has to multiply by 1. So, the third partial product is the multiplicand value namely 000100010. The fourth partial product is determined by next three bits i.e. to multiply by -1. Multiply by -1 means the multiplicand has to convert to two’s complement value. So, the forth…

I chose to research the box and whisker plot for my final project, because I remember when I learned it in high school that I enjoyed it more than most math things. I could also understand how it worked better, so I thought that I could explain it better in my paper and in the presentation than the other topics. The box and whisker plot is used to show the shape of the distribution, it's central value, and it's variability. Before Barry Manilow's 74th birthday, he started to wonder, what are the…

Raw class data between scaling variables and maximum jumping performance were recorded in Table 1. These combined results were then studied using both the regression and correlation analysis methods to predict which morphological traits (body size, mass, muscle length and muscle circumference) determined the source of variation in toad locomotor performance; with the longest jump distance of the toads as the dependent variables and the various scaling variables as the independent variables. Then…

An 10X12 IR was used to produce the image and the SID was set at 40”. The Right Phantom foot was placed in the center of the IR. The CR was aligned perpendicular to IR to medial malleoli. A 4-sided collimation was created that included outer margins of the foot and ankle. A 68kVp, a 3.2mAs and a small FS was selected. The right marker was placed in IR. PACER Patient in a lateral recumbent position, affected side down. Flex affected limb 45°. Center and align ankle joint to CR. The plantar…

Differences between the Actions of Squirrels in an Urban and a Natural Environment Introduction: In this research project the actions of the Easter Grey Squirrel () was observed in two different environments. The Eastern Grey Squirrel was chosen to be observed because it is one of the most common types of Squirrels in the Midwest. The Eastern Grey Squirrel has a number of predators including humans, foxes, hawks, and even owls. This is why it remains vigilant during the day, keeping a close…

results appear to support the findings in the experiment by Borniger, where they found that in a little bit of light, there was decrease in metabolic rate of mice (Borniger et al., 2014). Also 16 mgO2 /(L*hr*kg) is not a big difference of change in mean metabolic rate by the…
