The mean, median, and mode are all measures of central tendency. The mean is usually the preferred measure of central tendency,
padilas [110]

Answer and explanation:

1. It is commonly referred to as the arithmetic average: the mean measure of central tendency is also referred to as the arithmetic mean or arithmetic average or just average.

It is algebraically defined (that is, there is an equation you can use to calculate its value): the mean can be represented by the algebraic equation

a1+a2+a3...ai/n

2. There can be more than one median where there are an even number of data points and not odd number, in which the two middle number are divided by 2

It can be found when there are undetermined scores: median can be found with undetermined scores

3. It corresponds to an actual score in the data: the mode is an actual value in the data that appears more frequently than other values

There can be more than one: there can be more than one mode(bimodal,trimodal,multimodal) where 2 or more values appear the same number of times

german

Answer:

El ascensor recorrió unos 39 metros

Step-by-step explanation:

Segun la pregunta cada cada piso tiene 3 metros de altura, por lo tanto para calcular los metros que recorrió el ascensor tenemos que hacer el siguiente calculo:

metros desde el primer piso al quinto piso=3 metros*4=12 metros

metros desde el quinto piso al segundo piso=3 metros*3=9 metros

metros desde el segundo piso al octavo piso=3 metros*6=18 metros

Por lo tanto los metros que recorrió el ascensor=12 metros+9 metros+18 metros

metros que recorrió el ascensor=39 metros

El ascensor recorrió unos 39 metros
