To solve the first question in the image:

1. **Panjang interval kelas pada tabel distribusi frekuensi di atas** (Class interval length):

The interval length is calculated by subtracting the lower bound of a class from the upper bound.

For example, for the first class interval (40–49), the length is:
\[
49 - 40 + 1 = 10
\]

Therefore, the correct answer is **e. 10**.
