Student Running Times and Percentages

The video tutorial explains how to determine the percentage of students who ran a mile in 12 minutes or less. It involves analyzing time intervals, calculating the total number of students, and using these figures to compute the percentage. The process includes identifying relevant time intervals, summing the frequencies, and performing a division to find the percentage, which is then converted from a decimal.

What is the main objective of the problem discussed in the video?

• To calculate the total number of students who participated in the run.

• To identify the percentage of students who ran a mile in 12 minutes or less.

• To find the average time students took to run a mile.

• To determine the fastest time recorded by a student.

Which time interval should be included in the calculation?

• 13 to 14 minutes

• 9 to 10 minutes

• 17 to 18 minutes

• 15 to 16 minutes

Why are the intervals 13 to 14 and 15 to 16 minutes excluded?

• They have no students in them.

• They represent times slower than 12 minutes.

• They represent times faster than 12 minutes.

• They are not relevant to the problem.

How do you calculate the percentage of students who ran the mile in 12 minutes or less?

• Add the number of students who ran in 12 minutes or less to the total number of students.

• Divide the number of students who ran in 12 minutes or less by the total number of students.

• Subtract the number of students who ran in 12 minutes or less from the total number of students.

• Multiply the number of students who ran in 12 minutes or less by the total number of students.

What is the decimal result of dividing 14 by 34?

• 0.75

• 0.4117647

• 0.5

• 0.25

How do you convert a decimal to a percentage?
