Vamos estimular o pensamento matemático, a partir de um problema com o índice de massa corporal
Resumo
In this problem it is required to analyze the possibility that the arithmetic mean of the body mass index (BMI) of the members of a group of people remains within a certain range, when changing one of the members of the group by another person whose mass is greater than that of the replaced person. The fact of not knowing the number of members of the group, nor their BMI, is used to stimulate mathematical thinking through the construction and analysis of particular cases that, in turn, provide elements for a general analysis. A look at the problem using two variables functions is included and it is concluded with some didactic-mathematical comments.
