A group of 50 learners has the following masses in kg: [list of masses]. Calculate the number of learners whose mass exceeds 38 kg.

Here are the solutions for the math items.

Item 1: Learner Mass Analysis

Step 1: Count the total number of learners and those whose mass exceeds 38 kg.
The total number of learners is 50.
The learners with mass exceeding 38 kg are:
55, 63, 56, 40, 43, 66 (6 learners)
55, 58, 72, 48, 49, 50, 51, 52, 53, 58 (10 learners)
53, 54, 45, 41, 56, 39, 5
