    Answer:

    Jaw saw an average of 6 birds each day

    Step-by-step explanation:

    Given: One day, Jean saw 7 birds. The next day, she  saw 11 birds. The next day, she saw no birds.

    To find: average number  of birds Jean saw each day

    Solution:

    Average is a central value of a set of terms.

    Average of terms x_1,x_2,x_3,...,x_n is given by \frac{x_1+x_2+x_3+...+x_n}{n}

    Number of birds, Jean saw on day one (x_1) = 7

    Number of birds, Jean saw on the second one (x_2)  = 7

    Number of birds, Jean saw on the third one (x_3) = 7

    So,

    average number  of birds Jean saw each day = \frac{x_1+x_2+x_3}{3} =\frac{7+11+0}{3}=\frac{18}{3}=6

    Therefore,

    Jaw saw an average of 6 birds each day
