Question

Media aritmetica a 7 numere naturale este 23.Stiind ca primul numar este 11,calculati media aritmetica a celorlalte 6 numere. VA ROG REPEEDEEE

Answer 1

(a+b+c+d+e+f+g):7=23

11+b+c+d+e+f+g=23x7=161

b+c+d+e+f+g=161-11=150

ma (b+c+d+e+f+g)=150:6=25

Answer 2

(a+b+c+d+e+f+g)/7=23; a+b+c+d+e+f+g=161; 11+b+c+d+e+f+g=161; b+c+d+e+f+g=150; (b+c+d+e+f+g)/6=150/6; (b+c+d+e+f+g)/6=25
