Question

in a school survey, 40% of students said their favorite subject is math, science, and history. there were 250 students who responded to the survey. a) how many students chose math, science, and history?

Explanation:

Step1: Calculate the percentage of students who chose math or science

The percentage of students who chose history is \(18\%\). The total percentage of students is \(100\%\). So the percentage of students who chose math or science is \(100\% - 18\%=82\%\)

Step2: Calculate the number of students who chose math or science

There are \(n = 250\) students in total. To find the number of students who chose math or science, we use the formula \(x=n\times p\) (where \(p\) is the percentage in decimal form). Since \(p = 0.82\) and \(n = 250\), then \(x=250\times0.82 = 205\)

Answer:

\(205\)
