We believe that new materials and didactic models of this type have great educational potential because they encourage the analysis and understanding of various probability problems (Panizza, 2003). Accurate communication between teachers and students in the approach, interpretation, resolution, and testing of probability problems is of vital importance. The software used for this purpose is the MATHEMATICA program, a tool that facilitates the writing of formulas and calculations, as well as the construction of graphs, through a friendly interface, facilitating the self-taught work of the student and encouraging the development of analysis skills and problem solving.

This work presents a detailed description of the terms defined in the concept of curvature. It is of great importance that students from engineering courses understand this concept with certainty and confidence, because it will allow perceiving abstract terms, such as radius of curvature, osculating circle, normal vector; thus, they will have complete handling in the basic description of the movement of bodies.

The prevalence of obesity in adults in the state of Guerrero in 2012 was 71.5% (Barquera, 2012) The objective of this research was to generate a diagnosis of these conditions in both urban and rural locations in the seven regions of the state of Guerrero. The information was analyzed using an information system called SIOB, which is a technological tool developed to collect information from the population with a sample of 23,000 people, users of the public health sector of the state of Guerrero. We used the Weka tool of the University of Waikato (Eibe et al., 201d6) to generate a visible decision tree that shows the prevalence of these conditions in the state of Guerrero. It is considered that these visualization tools can help in the implementation of public policies that contribute to the prevention of these chronic degenerative diseases.","PeriodicalId":367381,"journal":{"name":"Journal Mathematical and Quantitative Methods","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121999818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It talks about the different types of simulation models that can be applied in mining operations such as stochastic, deterministic and discrete events. The underlying idea of this text is to highlight that with the increase in competitiveness, mining companies are in need of using simulation techniques to reduce costs, time and risks when making decisions, since simulation allows the creation of scenarios that approximate reality. In the end, the document concludes that simulation models are a tool to help in decision-making, for the optimization of resources, increased improvement and efficiency of the processes of loading, transport and unloading in open pit mines.","PeriodicalId":367381,"journal":{"name":"Journal Mathematical and Quantitative Methods","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123020455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
