The speed of the wind is changing according to the function V(t) = - +30, where t = time in minutes after 6:00p.m. an V(20) - V(10) = -5 ?
In a period of 5 minutes, the wind speed increased from 10 mph to 20 mph.

THE ANSWER IS BE smart wowiwiwiiw

Third option is correct.

Step-by-step explanation:

Statistical questions are those in which we get more than one numerical answer.

According to options,

In option 'A' how many theatres are there in my city, we get only one numerical value instead of collection of data.

In option 'B' how many students like classic movies in my class , in which we get only one numerical value.

In option 'C' how many movies do the students in my class watch in a month.

In this option we would get a collection of data i.e. more than one numerical value.

Because not every student watch same number of movies in a month.

In option 'D' again we get only one numerical value.

Hence, Third option is correct.
