saw 11 birds. The next day, she saw no birds. What is the average number
of birds Jean saw each day? *

Answer 1

Jaw saw an average of 6 birds each day

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
`(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 =
`(x_1+x_2+x_3)/(3) =(7+11+0)/(3)=(18)/(3)=6`

Therefore,

Jaw saw an average of 6 birds each day
