Asurvey asked 10 boys and 10 girls how many hours they spent playing video games the previous week. the number of hours are given in the line plots. two line plots one above the other, both are labeled from two to twenty by twos. the top line plot is labeled boys and it has three xs above ten, two xs above fifteen and one x above eight, twelve, thirteen, fourteen and twenty. the bottom line plot is labeled girls and it has three xs above four, two xs above ten and one x above three, six, seven, eight and fifteen. select from the drop-down menus to complete each statement. the data set with the greater range is . the median . pic:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
