Why not just write 82? It better if you write each score out completely,
Does "7:2 ,5,5,5,8,8,8,8,9" mean 72, 75, 75, 75, 78, 78, 78, 78, 79. If so, count the 78s.
the other two you have to do on your own though

4 students scored 78. 2 years late SRRYYYYY.
Answer is 4
Reasoning-
because the number in the right section is the tens place while the numbers on the right are the ones place. Therefore using this logic if it says 7:8,8,8,8 that means it’s 4.
To determine how many students scored 78, we need to analyze the stem-and-leaf plot. In the stem-and-leaf plot provided, the stem represents the tens digit of the scores, and the leaf represents the units digit.
Looking at the stem "7", we see that there is only one leaf, which is "8". This means that there is one student who scored 78. Therefore, the answer is 1.
