Răspuns :
calculezi media aritmetica a numerelor respective si dupa calculezi media aritmetica +102 si imparti la 5..dupa scazi medile si ai diferenta
[tex]m_a_1=\frac{101+102+103+104}{4}\\
m_a_1=\frac{410}{4}=\ \textgreater \ m_a=102,5\\
m_a_2=\frac{101+102+103+104+102}{5}\\
m_a_2=\frac{512}{5}=102,4
m_a_1-m_a_2=102,5-102,4=0,1[/tex]
