Suppose 7/10 of people surveyed agree that dogs are the best pets to own. How many people would you have to select randomly, on average, in order to get 30 people who DO NOT think dogs are the best pets to own?

100 people

Step-by-step explanation:

7/10 of people surveyed agree that dogs are the best pets to own. This means: 1 - 7/10 = 3/10 do not think that dogs are the best pet to have.

Let the total number of people selected randomly be x.

3/10 × x = 30

3x/10 = 30

3x = 30 × 10

3x = 300

Divide both side by 3

3x/3 = 300/3

x = 100

100 people will be selected randomly.
