Question

Increasing life expectancy. A smoker is 15 times more likely to die of lung cancer than a nonsmoker. An ex-smoker who stopped smoking t years ago is w times more likely to die of lung cancer than a nonsmoker, where
w = 15 – t.

Graph the equation and use the graph to estimate how much more likely it is for Sandy to die of lung cancer than Polly, if Polly never smoked and Sandy quit 2 1/2 yrs ago.

Answer 1

polly is nonsmoker
sandy is ex- smoker
t= 2 1/2= 5/2 years
w= 15-t = 15- 5/2 = 25/2

so sandy is 25/2 more times likely to die than polly

Answer 2

so how do i graph this answer

Answer 3

im so lost

Answer 4

do you wanna draw graph,,?

Answer 5

yes, what points to draft?

Answer 6

take t on x-axis starts from 0 to ....at origin and w on y-axis starts from 0 to...15

now match the respective points of sandy and polly

Answer 7

so plot (0,0)?

Answer 8

thats origin...for polly..

Answer 9

so what nmber is the plot for sandy?

Answer 10

sorry ...t=0 so w= 15-0=15 for polly

so (0,15) plolly and (5/2,25/2) sandy

Answer 11

the graph will be up to down starting from 15 on y - axis

Answer 12

i know how to plot for y

Answer 13

but x how do i plot 5/2 and 25/2, when i divide it comes out to decimals, it doesn't make sense to me...
