Question

imi faceti media ponderata dintre numerele 7 6 5 4 4 3 si 3 in teza

Answer 1

media aritmetica =media ponderata, deci nu te ajuta cu nimic
Ma=(7+6+5+4+4+3)/6=29/6=4,8(3),  
Mponderata=(7+6+5+2x4+3)/4+2x1=4.8(3)
Mgenerala=(4,8(3)+3)/2=3,91(6)

Answer 2

7+6+5+4+4+3=30
30÷6=5
Nota de trecere e 5.
Teza trebuie revazuta.
