A, D, and E are true

One X on the line plot marks one time something happened. So the two x’s above the 1 means that he practiced piano for one hour (see to the right that says hours next to the numbers, so 1=1 hour) two times.

45 minutes is 3/4 of an hour, and is the mark right between 1/2 and 1. There is one x above this mark, so that means Thaddeus practiced for 45 minutes one time, so B is false

Thadeus practiced piano for 30 minutes two times, so C is false because he didn’t mostly practice for thirty minutes.

D is correct because there are 2 Xs above the 0, which means two times he practiced for zero hours, which means he didn’t practice at all.

E is correct because 15 minutes is 1/4 of an hour, so it is the mark between 0 and 1/2. We see there are three x’s there, so that means he practiced for 15 minutes 3 times.

I hope this helps! Let me know if you want me to explain it differently.
