Construct a scatter diagram using the data table to the right. this data is from a study comparing the amount of tar and carbon monoxide (co) in cigarettes. use tar for the horizontal scale and use carbon monoxide (co) for the vertical scale. determine whether there appears to be a relationship between cigarette tar and co. full data set tar co tar co tar co 16 15 9 11 2 3 9 10 8 11 12 12 1 1 14 13 6 7 16 17 18 18 11 12 5 7 9 9 10 11

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

i'm sorry i don't know
