When ever I encounter problem like this, I make the equation become:
z = anything buy z.
First, you want to get 2/5 to the other side, to do so, you need to multiply 5/2 on both side. then you are left with z+1=5/2 y. Then you subtract 1 from both sides to make z on its own. The answer should be z = 3/2y or z= 1
y
2/5(z+1)=y
2/5(z+1)5/2=5/2y
z+1=5/2y
z+1-1=5/2y-1
z=3/2y or z=<span>1y</span>
z = anything buy z.

Using the percentage concept, it is found that the correct option is given by:
There is a positive association because the percentage of residents living in a house that have a dog is greater than the percentage of all residents who have a dog.
<h3>What is a percentage?</h3>The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
Of the 38 people in houses, 17 have dogs, hence the percentage is given by:
pH = 17/38 = 44.74%.
Out of all residents, the percentage is given by:
pA = 21/66 = 31.82%.
The percentage in houses is considerably greater than for all residents, hence the statement that explains the positive association is given by:
There is a positive association because the percentage of residents living in a house that have a dog is greater than the percentage of all residents who have a dog.
