A random survey found that 7 of the 10 people surveyed prefer pizza. Based on those results, about how many people prefer pizza from a population of 60 people?
To estimate how many people out of a population of 60 prefer pizza, you can use a proportion:
7 out of 10 people prefer pizza
x out of 60 people prefer pizza
7/10 = x/60
10x = 7 * 60
10x = 420
x = 420/10
x = 42
Based on the survey results, about 42 people out of a population of 60 would prefer pizza.
