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 [tex]x_1,x_2,x_3,...,x_n[/tex] is given by [tex]\frac{x_1+x_2+x_3+...+x_n}{n}[/tex]
Number of birds, Jean saw on day one [tex](x_1)[/tex] = 7
Number of birds, Jean saw on the second one [tex](x_2)[/tex] = 7
Number of birds, Jean saw on the third one [tex](x_3)[/tex] = 7
So,
average number of birds Jean saw each day = [tex]\frac{x_1+x_2+x_3}{3} =\frac{7+11+0}{3}=\frac{18}{3}=6[/tex]
Therefore,
Jaw saw an average of 6 birds each day
