Question

Calculati media aritmetica a numerelor

a) x= 127,38 si y=132,62

b) x= 2,8(3) si y=1,1(6)

Answer 1

a) x=127,38
    y=132,62
    Ma=(127,38+132,62):2
    Ma=260:2
    Ma=130

b)  x=2,8(3)=283-28 /90=255/90
     y=1,1(6)=116-11 /90=105/90
    Ma=(255/90+105/90):2
    Ma=(360/90):2
    Ma=4:2
    Ma=2
