En el año 2013 la empresa británica Biomatrix, diseñó un sistema ecológico de tratamiento de aguas contaminadas urbanas que logra recuperar la calidad del agua y revitalizar el paisaje a un costo bastante bajo. Este tratamiento consiste en cada 6 horas instalar un reactor que permite oxigenar el agua, cada 18 horas ubicar una colonia de bacterias que se alimentan de la contaminación y finalmente cada 12 horas, crear islas flotantes con diversas plantas que mejoran la circulación del rio. Si el día de hoy a las 00:00 horas se inicia el tratamiento, ¿Cuántas veces coincidirán las tres etapas a lo largo de 3 días?

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
