(a) Amy pumped 35 gallons of water out of her pool. This was done over a period of 5 minutes at a constant rate. What was the change in the amount of water in the pool each minute?

7 gallons

Step-by-step explanation:

35 gallons: 5 minutes

find constant rate(one min per x number of gallons)

35:5

divide by 5 to get one minute

7:1

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
