absorbed in the food coloring over time decreases. To find the concentration of the solution the equation for Beer’s law was used. Knowing A‚ є‚ and b‚ it was possible to solve for c and graph the points in the Concentration vs. time graph. This graph shows that over time the concentration of the food coloring is decreasing in the bleach. This function is for a zero-order reaction‚ and as it was not linear‚ it is not a zero-order reaction. The natural log of the concentration is for a first order

Date: 5th March 2010 Abstract Bone lengths can be used to provide stature estimations in case of unidentified skeletal remains‚ an important tool in forensic and bioarchaelogical cases. Where the bones are broken or fragmented‚ regression equations can be used to estimate total bone length from its fragments‚ which in turn can be used to estimate stature. The aim of this study was to test 2 new measurements of the femoral shaft to see if they could be used as predictors of maximum femoral length

Regression Analysis The concepts and principles developed in dealing with simple linear regression (i.e. one explanatory variable) may be extended to deal with several explanatory variables. We begin with an example of two explanatory variables‚ both of which are continuous. The regression equation in such a case becomes: Y = α + β1x1 + β2 x2 It is customary to replace α with β 0‚ and so all future regression equations would be written as Y = β0 + β1x1 + β2x2 ……βnxn Regression with two explanatory

Search patterns vary and depend on the type of scene‚ the victims and suspect’s actions as well as the location and size of the area. Having someone in command can eliminate or lessen the chances of evidence or effort being duplicated. While each scene and victim may need a different search pattern‚ each pattern searches the probable points of entry first and any exits possibly used by the criminal. A line/strip search is one that is used by one or two investigators who walk in straight lines

The simplest single – equation linear regression model is: Y = β0 + β1X βs – coefficient that determine the coordinates of the straight line at any point β0 – is the constant or intercept term‚ it indicates the

chemical reactions. A certain run from the previous task was twice duplicated to for a “hot and cold” test for reaction rate. The prior run was again duplicated for a test with catalyst. The data obtained was graphed in a linear regression form‚ using the Arrhenius equation: lnk=-EaR-1T+lnA‚ reaction rate: rate = k[A]x[B]y and other principles held in chemistry. The graph from the results determined that there is a relation between rate and the previously mentioned factors. The results validated

Invertible matrix From Wikipedia‚ the free encyclopedia (Redirected from Nonsingular matrix) Jump to: navigation‚ search In linear algebra an n-by-n (square) matrix A is called invertible (some authors use nonsingular or nondegenerate) if there exists an n-by-n matrix B such that where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case‚ then the matrix B is uniquely determined by A and is called the inverse of A‚
