Answer:

12

Step-by-step explanation:

Quartiles are statistical measures that divide a dataset into four equal parts, representing values below which a specified proportion of the data falls.

  • The first quartile (Q1) represents the 25th percentile, meaning 25% of the data falls below this value.
  • The second quartile (Q2), also known as the median, represents the 50th percentile, meaning 50% of the data falls below this value.
  • The third quartile (Q3) represents the 75th percentile, meaning 75% of the data falls below this value.

Since Q3 is 10 minutes, 75% of the rides are less than 10 minutes long.

Therefore, we would expect about 75% of the 16 rides to be less than 10 minutes long:

[tex]\sf 75\% \; of \; 16\;rides = \dfrac{75}{100}\times 16=\dfrac{1200}{100}=12\;rides[/tex]

So, approximately 12 rides would be less than 10 minutes long.
