Ludmilka [50]

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
