8. A survey showed that 56% of car owners prefer four-door cars, 31% prefer two-door cars, and 13% have no preference. You ask 300 people. How many do you think will prefer four-door cars? (1 point)
Out of 300 people, approximately 0.56 x 300 = 168 people will prefer four-door cars.
To find out how many people would prefer four-door cars, we can use the given percentages.
56% prefer four-door cars, which means 56 out of 100 people prefer four-door cars.
To calculate the number of people who prefer four-door cars out of 300, we can set up a proportion:
56/100 = x/300
Using cross-multiplication, we can solve for x:
100x = 56 * 300
Dividing both sides by 100:
x = (56 * 300) / 100
Performing the calculation:
x = 16800 / 100
x = 168
Therefore, out of the 300 people surveyed, it can be estimated that around 168 people will prefer four-door cars.
