Linear equation

Predictive Analytics Questions Answered How can predictive models impact business decisions? Otherwise, one is forced to look at millions of rows every day and make decision. Human brain has non linear thinking to do this but, memory is limited. so we will end up doing the same thing over and over again. Predictive algorithms free human brain from its limitations and performs algorithms on computers do what human brains are not capable of- looking millions of records for each of at least three…

Technology: Past vs. Modern The earliest humans created technology in order to help them solve for their needs, they used stones, woods and other materials to manufacture the simplest and most original tools. After that, the younger generation used ancestral experiences and wisdom to continuous improvement and innovation technology in every period. That’s why we have today’s high-technology. Technology is developing faster and faster in each year, however, that’s resulting in people losing…

Equations (1.4) and (1.5) can be combined to obtain the equation for piezoelectric polarization as, P_pz=2 (a_s-a_o)/a_o (e_31-c_13/c_33 e_33) (1.6) The total polarization P tot is calculated by summing together the two polarization components: P_tol…

Harmonics: Harmonic distortions are injected at the generation as well as the consumer end. At the consumer end, harmonics are caused by nonlinear loads such as PCs, CFLs, electronic devices, etc. The harmonics distortion caused by non-linear load such as electric arc furnaces, large concentrations of arc discharge lamps, variable speed motors, saturation of magnetization of transformer and a distorted line current. The current generated by such loads will interact with power system impedance…

The search for the origins of humankind and the earliest human ancestor has intrigued anthropologists for generations. New evidence, while often scarce, is a vital aspect to the understanding and development of the field of paleoanthropology. Current research aids in the modification of the human ancestral tree and the analysis of various sites. One of the newest sites dealing with human evolution is the Rising Star cave system in South Africa, where a new species of human ancestors, Homo naledi…

Prepared by: Ahmed Alrahmani Prepared to: Dr. Maohong Fan Subject: Heat Transfer from Steam to Water Date: 11/01/2013 Summary: The objective of this experiment was to investigate the overall heat transfer ( Uₒ ) for the external heat exchanger at two different water circulation rates by using two methods “ Heating Liquids in Tank Storage ” and “ Corning Heat Exchanger “ . Briefly, the measurements were done by changing the volume flow rate between 40 lbm/min and 70 lbm/min for the first…

phenolphthalein was added and the content stirred on a plate stirrer with magnet to fully solubilize pectin.. The solution was titrated against 0.1M NaOH solution till PH 7.5 was attained (when the colour just started to turn pink). The following equation was applied to establish equivalent weight: Equivalent weight (EW)=(weight of pectin sample x 1000)/(volume of alakali (〖cm〗^3 )x Normality of Alkali) The…

A sample revealed three bags of 56, two bags of 57, one bag of 55, and two bags of 58. To test the hypothesis that the mean candies per bag is 56, how many degrees of freedom are there? * 8 * 9 * 7 * 1 Which of the following is most appropriately displayed with a frequency table? * What percentage of people prefer Hunt's brand ketchup * The home location of the most valuable customers * The relationship between gender and job performance *…

In the above figure shown, in blue is the vocal motor output pathway, where the signal begins in the HVc (High vocal center) which…

of rules and theorems that seemed only relevant for that section. We learned about sine, cosine, and tangent, which were chiseled in our brain. In high school we were introduced to things I didn’t know existed, such as derivatives, 4-step problems, linear regression lines. When I am asked the question what is math, I still seem to divert my attention to the elementary school response and explain that math is finite and always has an answer despite my knowledge that it doesn’t…
