Final answer:
The codes that go into block 20 of an evaluation can vary depending on the specific evaluation system or programming language being used. Block 20 is often used to store information related to the performance or results of an evaluation.
Step-by-step explanation:
The codes that go into block 20 of an evaluation can vary depending on the specific evaluation system or programming language being used. In general, block 20 is often used to store information related to the performance or results of an evaluation. For example, in a programming language like Python, block 20 may contain codes that calculate the average score of a student in a class using a loop and conditional statements. It could look something like this:
score_sum = 0
num_scores = 0
for score in scores:
score_sum += score
num_scores += 1
average_score = score_sum / num_scores
In this example, the codes in block 20 calculate the average score by summing up all the scores and dividing it by the total number of scores.
