Question

select the correct answer from each drop - down menu.
an organization asked 500 students, selected at random from high schools across the united states, whether they want fast food served in school cafeterias. the survey found that 79% of the students agreed that fast food should be introduced, 10% disagreed, and the rest had no view on this matter.
based on this data, of the 500 students want fast food served at the school cafeteria, and students have no view on this matter.

Explanation:

Step1: Calculate students wanting fast food

To find the number of students who want fast food, we use the percentage of students who agreed (79%) and multiply it by the total number of students (500). The formula is \( \text{Number of students} = \text{Total students} \times \text{Percentage} \). So, \( 500 \times 0.79 = 395 \).

Step2: Calculate students with no view

First, find the percentage of students with no view. The total percentage should be 100%, so we subtract the percentage of students who agreed (79%) and disagreed (10%) from 100%. That is \( 100\% - 79\% - 10\% = 11\% \). Then, we find 11% of 500. Using the formula \( \text{Number of students} = 500 \times 0.11 = 55 \).

Answer:

For the first drop - down: 395 (since \( 500\times0.79 = 395 \))
For the second drop - down: 55 (since \( 500\times(1 - 0.79 - 0.10)=500\times0.11 = 55 \))
