In the question,
Let the total number of geese be = 100x
Number of Male geese = 30% = 30x
Number of Female Geese = 70x
Let us say 'kx' geese migrated from these geese.
Number of migrated Male geese = 20% of kx = kx/5
Number of migrated Female geese = 4kx/5
So,
<u>Migration rate of Male geese</u> is given by,
<u>Migration rate of Female geese</u> is given by,
So,
The ratio of Migration rate of Male geese to that of Female geese is given by,
Therefore, the<em><u> ratio of the rate of migration of Male geese to that of Female geese is,</u></em>
<em><u>Hence, the correct option is (B).</u></em>

For this case we have the following expression:
By definition, a coefficient is the term that accompanies one or more variables.
For example:
The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
