53kg, 42kg, 41kg, 60kg, 44kg, 49kg. Calculate the mean weight giving your answer correct to two decimal places

Mean is simply the average of all numbers and to find it you add up all the numbers and divide for how many numbers there are (in this case we 6 numbers, 6 masses).

So, 53+42+41+60+44+49 = 289 kg

Mean = 289/6 = 48,1666666 ...

So 48,17 is your answer
