Frequency tables are used to represent datasets and their frequencies
The average number of miles he drove per month is 1358.3 miles
<h3>How to determine the average number of miles</h3>From the frequency table, the total number of miles travelled in a year is:
Total = 16300 miles
There are 12 months in a year.
So, the average number of miles is:
Divide
Hence, the average number of miles he drove per month is 1358.3 miles

Since A and B are the midpoints of ML and NP, we can say that AB is parallel to MN and LP. In order to find ∠PQN, we can work with the triangles PQB and NQB. According to SAS (Side-Angle-Side) principle, these triangles are congruent. BQ is a common side for these triangles and NB=BP and the angle between those sides is 90°, i.e, ∠NBQ=∠PBQ=90°. After finding that these triangles are equal, we can say that ∠BNQ is 45°. From here, we easily find <span>∠PQN. It is 180 - (</span>∠QNP + ∠NPQ) = 180 - 90 = 90°
