Answer 1

Answer:

93yr

Step-by-step explanation:

mean weight=Total weight/number of the objects

42=Total weight of students/50

Total weight of students=42*50

(mean weight+1)=(total weight of students +Teacher weight)/(50+1)

42+1=42*50+teacher weight/51

43*51=42*50+teacher weight

Teacher weight=43*51-42*50

Teacher weight=2193-2100

Teacher weight=93yr
