Question

in the country of chad infant mortality due to malaria has been greatly reduced thanks to insecticde treated bed nets. the percentage 'p' of insecticide remaining in treated bed net t years since the bed is first used can be modeled byt the following linear equation p(t)= -9.42t+ 99.4. is the y-intercept applicable why or why not? and interpret the slope?

Answer 1

The y-intercept is applicable. It shows the percentage of infant mortalitydue to malaria before the bed is first used.
The slope -9.42 shows that each next year when the bed is used the percentageof infant mortality decreases by 9.42%.
