Maribella spends less time on homework per night.
To answer this question, we need to compare the number of hours each person spends on homework per night.
From the table for Marco's homework, we can see that he spends 3.25 hours of homework in 3 days, which means he spends an average of 3.25/3 = 1.0833 hours per night.
From the table for Maribella's homework, we can see that she spends 4.2 hours of homework in 4 days, which means she spends an average of 4.2/4 = 1.05 hours per night.
Comparing these averages, we can see that Marco spends less time on homework per night, with an average of 1.0833 hours, while Maribella spends an average of 1.05 hours per night.
Therefore, the correct statement is:
Marco spends less time on homework per night.
To determine who spends less time doing their homework per night, let's calculate the average time spent per night for Marco and Maribella.
For Marco:
Average time per night = Total hours spent / Number of days
Average time per night = (3.25 + 9.75 + 13.0 + 32.5) / (3 + 9 + 12 + 30)
Average time per night = 58.5 / 54
Average time per night ≈ 1.08 hours
For Maribella:
Average time per night = Total hours spent / Number of days
Average time per night = (4.2 + 8.4 + 21.0 + 29.4) / (4 + 8 + 20 + 28)
Average time per night = 62.0 / 60
Average time per night ≈ 1.03 hours
Comparing the averages, we can see that Maribella spends less time on homework per night (approximately 1.03 hours) compared to Marco (approximately 1.08 hours).
Therefore, the correct statement is: Maribella spends less time on homework per night.

Community A has the most children. There are 2,600 children in this community if there are 1,000 households.
Community B has the most children. There are 2,500 children in this community if there are 1,000 households.
To determine which community has the most children if both neighborhoods have the same number of households, we need to compare the average number of children per household.
For Community A:
Average number of children per household = Total number of children / Number of households
Average number of children per household = (26 + 52 + 104 + 195) / (10 + 20 + 40 + 75)
Average number of children per household = 377 / 145
Average number of children per household ≈ 2.60
For Community B:
Average number of children per household = Total number of children / Number of households
Average number of children per household = (30 + 60 + 125 + 212.5) / (12 + 24 + 50 + 85)
Average number of children per household = 427.5 / 171
Average number of children per household ≈ 2.50
Comparing the averages, we can see that Community A has the most children, with an average of approximately 2.60 children per household, compared to Community B's average of approximately 2.50 children per household.
To find out how many children live in Community A if there are 1,000 households, we can multiply the average number of children per household by the number of households:
Number of children in Community A = Average number of children per household * Number of households
Number of children in Community A = 2.60 * 1,000
Number of children in Community A = 2,600
Therefore, the correct statement is:
Community A has the most children. There are 2,600 children in this community if there are 1,000 households.
