Answer 2

`55 (1)/(4) = 55.25;60 (1)/(2) = 60.5;70 (1)/(4) = 70.25;45 (3)/(4) = 45.75; \\ 50 (1)/(2) = 50.5;60 (3)/(4) = 60.75;65 (1)/(4) = 65.25;50 (1)/(4) = 50.25; \\ 45 (1)/(4) = 45.25;55 (3)/(4) = 55.75`

`(55.25 + 60.5 + 70.25 +45.75 + 50.5 + 60.75 + 65.25 + 50.25 + 45.25 + 55.75)/(10) = (559.5)/(10) = 55.95`
