Somebody , one quick problem (25 points): for making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the amount of fluoride? water (l) 1 0.5 0.8 2 1.5 0.5 2.5 fluoride (mg) 0.4 0.4 0.6 1.6 0.8 0.2 1.8

Fluoride ranges from 0.2 to 1.8. I'd use a scale from 0 to 2 with an interval of 0.2, since that seems to be the resolution of the data. That puts 10 intervals in the range, which is about the right amount. (You generally want between 5 and 20.)

Water ranges from 0.5 to 2.5, so I might use a scale from 0 to 3 with major intervals marked at 0.5 and minor intervals at 0.1. You'd like to have all data points be on grid lines, but with one at 0.8 and several at multiples of 0.5, some compromise is needed.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
