Question

Calculati media artitmetica si media geometrica a numerelor a si b in fiecare dintre cazurile a=27 si b=48

Answer 1

media aritmetica =
$\frac{a + b}{2} = \frac{27 + 48}{2} = \frac{75}{2} = 37.5$
media geometrica =
$\sqrt{a \times b} = \sqrt{27 \times 48} = 9 \times 4 = 36$

Answer 2

Ma=(27+48)/2=75/2=37,5
Mg=radical din 27x48=radical din 1296=36
