Based on the tables, it can be concluded that Marco spends less time on homework per night.
To compare the time spent on homework by Marco and Maribella, we can look at the number of hours they spent on different numbers of days.
From the given tables, we can see that:
Marco:
- On 3 days, Marco spent 3.25 hours on homework.
- On 9 days, Marco spent 9.75 hours on homework.
- On 12 days, Marco spent 13.0 hours on homework.
- On 30 days, Marco spent 32.5 hours on homework.
Maribella:
- On 4 days, Maribella spent 4.2 hours on homework.
- On 8 days, Maribella spent 8.4 hours on homework.
- On 20 days, Maribella spent 21.0 hours on homework.
- On 28 days, Maribella spent 29.4 hours on homework.
Comparison:
- On all corresponding days, Maribella spends more time on homework than Marco.
- If we consider the average time spent per day, we can calculate it by dividing the total hours by the total number of days.
- For Marco: (3.25 + 9.75 + 13.0 + 32.5) / (3 + 9 + 12 + 30) ≈ 2.131 hours per day
- For Maribella: (4.2 + 8.4 + 21.0 + 29.4) / (4 + 8 + 20 + 28) ≈ 1.707 hours per day
- Based on the average time spent per day, Marco spends less time on homework per night compared to Maribella.
Therefore, the correct statement is:
Marco spends less time on homework per night.
To answer the question, we need to compare the average time spent on homework per night by Marco and Maribella.
To find the average time spent on homework per night, we need to divide the total number of hours by the total number of days.
For Marco:
Average time spent per night = Total number of hours / Total number of days
Average time spent per night = (3.25 + 9.75 + 13 + 32.5) / (3 + 9 + 12 + 30)
For Maribella:
Average time spent per night = Total number of hours / Total number of days
Average time spent per night = (4.2 + 8.4 + 21 + 29.4) / (4 + 8 + 20 + 28)
Now, let's calculate the averages.
For Marco:
Average time spent per night = 58.5 / 54 ≈ 1.083
For Maribella:
Average time spent per night = 63 / 60 ≈ 1.050
Since the average time spent on homework per night for Marco is less than the average time spent per night for Maribella, the correct statement is:
Marco spends less time on homework per night.
