An architect is designing a water fountain for a park she uses the given function to model the water jet flowing from the fountain nozzles where h(x) gives the height of the water jugs in feet x feet from the starting point h(x)=-1/20x+x+15

Xf(x) = 2x + 5 1 7 2 9 3 11 4 13 5 15 6 17 linear functions grow by equal differences over equal intervals. in the table above, what column could be added to prove this relationship?

The table shows the distances travelled by a paper aeroplane. a. find the range and interquartile range of the data. the range is feet. the interquartile range is __feet. b. interpret the range and interquartile range of the data. __ feet the distances travelled by the paper aeroplane varied by no more than__ feet. the middle half of the distances travelled by the paper aeroplane varied by no more than __ feet.
