Final answer:
To find the music types chosen by 40% of the surveyed people, 40% of 55 people is calculated, which equals 22 people. Those music types liked by 22 individuals represent the 40% music preference.
Step-by-step explanation:
To determine which types of music were chosen by 40% of the people Maribel surveyed, we must first calculate 40% of the total number of people surveyed. Maribel surveyed 55 people, so:
To find out which types of music were chosen by 40% of the people surveyed, you need to multiply the total number of people surveyed by 40% (or 0.40). In this case, 40% of 55 is 22. So, 22 people chose the favorite types of music that were selected by 40% of the surveyed people.
40% of 55 = 0.40 × 55 = 22 people
Therefore, the types of music chosen by 22 people represent the music preferences that correspond to 40% of the surveyed population.
