To create a dot plot from the provided data, we will represent each student's score with a dot above the corresponding score.
Here is the breakdown of the scores and dots above each score:
- Score 45: 10 dots
- Score 46: 7 dots
- Score 47: 4 dots
- Score 48: 8 dots
- Score 49: 3 dots
- Score 50: 1 dot
Now, we are specifically interested in how many dots will be above the number 47.
According to the dataset, there are 4 students who achieved a score of 47. Therefore, there will be 4 dots above the number 47 in the dot plot.
So the answer is:
4
