Uma escola Estadual de Ensino Fundamental e Médio possui 600 alunos matriculados e neste periodo de isolamento social, os professores têm oferecido atividades remotas através de plataformas que podem ser retiradas na escola semanalmente para os alunos que não possuem acesso a internet. A tabela abaixo fornece a quantidade de alunos desta escola que realizam as atividades de algumas disciplinas oferecidas remotamente por semana: -me média quantos estudantes fazem as atividades de matemática por semana? A. 55 B.54,2 C.55,4 D.52,4 - qual a mediana da quantidade de estudantes qur realizam a atividades de matemática? A.8 B.48 C.185 D.22 - Qual a moda da quantidade de estudantes que realizam a atividade de matemática? A.8 B.22 C.48 D.185

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

answer: i'm not sure

step-by-step explanation:

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
