A coordinate plane is titled: Number of Laps Swam. It shows day on the x-axis from 0 to 7 in increments of 1. It shows number of laps on the y-axis from 0 to 20 in increments of 1.
The approximate data points are as follows: left parenthesis 1 comma 18 right parenthesis, left parenthesis 2 comma 21 right parenthesis, left parenthesis 3 comma 14 right parenthesis, left parenthesis 4 comma 15 right parenthesis, left parenthesis 5 comma 11 right parenthesis, left parenthesis 6 comma 15 right parenthesis, and left parenthesis 7 comma 9 right parenthesis.

To determine which scatterplot correctly represents the data provided in the table for the number of laps swum per day, we need to analyze the given points based on the table:

  • Day 1: 18 laps
  • Day 2: 12 laps
  • Day 3: 10 laps
  • Day 4: 15 laps
  • Day 5: 13 laps
  • Day 6: 20 laps
  • Day 7: 9 laps

Now, let's clarify each coordinate of the data points (day, laps):

  1. (1, 18)
  2. (2, 12)
  3. (3, 10)
  4. (4, 15)
  5. (5, 13)
  6. (6, 20)
  7. (7, 9)

Now, we review the descriptions of the scatterplots:

  1. The first scatterplot contains incorrect data points for days 2 and 3.
  2. The second scatterplot matches the points: (2, 12) for day 2 and (3, 10) for day 3.
  3. The third scatterplot has incorrect data for day 3.
  4. The fourth scatterplot has day 6 showing 14 laps, which is also incorrect.

Since we are looking for the scatterplot that correctly corresponds to all the data points from the table, the second scatterplot is the correct answer as it accurately represents the data points provided.

So the answer is the second scatterplot.
