The mean mass of a squad of 19 hockey players is 82 kg. A player of mass 93 kg joins the squad. work out the mean mass of the squad now

82.55kg

Step-by-step explanation:

Calculate the total weight of the 19 hockey players: 19*82=1558kg.

Calculate the total weight of new players: 1558+93=1651kg.
