d. linear association

 B. positive association and D. linear association

Step-by-step explanation:

From the graph we can see the dots are moving upwards but  in a certain direction .

Thus, option B and option D will describe the scatter plot.

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)

don't know what that says sorry i can't you
