Question

Um aluno obteve as seguintes notas: 7,0 - 6,0 - 9,0 - 5,0 - 9,0 - 8,0 Determine, a média, a moda e a mediana das notas desse aluno

Answer 1

Média: 
Me = 5,0 + 6,0 + 7,0 + 8,0 + 9,0 + 90 
Me = $\frac{44,0}{6}$
Me = 73,3

Moda: 
Mo = 9,0 (Por ser o valor que mais aparece)

Mediana:
Md = 5,0 - 6,0 - 7,0 - 8,0 - 9,0 - 9,0
Md = $\frac{7,0 + 8,0}{2}$
Md = $\frac{15,0}{2}$
Md = 7,5

Answer 2

Resposta:

Explicação passo-a-passo:

7,0 + 6,0 + 9,0 + 5,0 + 9,0 + 8,0 = 44

44 % pela quantidade de notas (6)= 7,3

Talvez tenha na alternativa para arredondar

mas o correto sem arredondar é 7,3
