Final answer:
Without having the actual stemplot, we are not able to determine the number of games in which the team scored at least 70 points. Typically, in a stemplot, the stems represent the tens place and leaves represent the ones place, where stems '7' and above would indicate scores of 70 points and higher.
Step-by-step explanation:
To answer the student's question regarding the basketball team's scoring record, we must understand how to read a stemplot (stem-and-leaf plot). However, the question mentioned does not provide the actual stemplot, but in a typical scenario, the stems represent the tens place of the scores, while the leaves represent the ones place. If we had the stemplot, we would look for stems representing '7' and above, as these would correspond to scores of at least 70 points.
Assuming we had a stemplot, and the leaves for stem '7' were '0', '1', and '2', it would mean the team scored 70, 71, and 72 points in three different games. If there were more leaves on the stem '7' or any stems higher than '7', those would also represent games where the team scored at least 70 points. The number of these leaves would provide the answer to the student's query about how many games the team scored at least 70 points.
