Or, you could: ⤺ Go back to the previous part There's nothing more to do from here. Advice a) To find the mean you first need to sum the numbers, i.e.: \[ \simplify[]{{a}+{b}+{c}} = \var{a+b+c} \] Then divide through by the number of values being summed: \[ \text{Mean} = \simplify{{a+b+c}/3} \] b) The mean is \[ \simplify[]{({a}+{b}+{f}+{c}+{d})/5} = \simplify[fractionnumbers]{{(a+b+f+c+d)/5}} \] \( \endgroup \) Score: 0/2 Total 0/2 Move to the next questionTry another question like this oneReveal answers
