    a. 17.7

    b. 18

    Step-by-step explanation:

    To calculate the mean we will have to sum up the whole given value divided by the numbers

    So let's solve

    a. 5+31+20+1+7+8+29+27+14+35/10

    177/10

    17.7

    Therefore the final answer is 17.7

    b. Since another value is added

    It will be

    177+21/11

    198/11

    18

    Therefore the final answer is 18
