The mean is  55

Step-by-step explanation:

Given;

x                          y                              xy

10                         7                             70

30                        8                             240

50                        10                            500

70                        15                            1050

89                        10                            890

Now as we know the mean is given by

\overline{x} = \dfrac{\sum f_ix_i}{\sum f_i}

Therefore we have

\overline {x} = \dfrac{70+240+500+1050+890}{7+8+10+15+10} =\dfrac{2750}{50} =55

Hence the mean is 55
