Determine the type of sampling used (simple random, stratified, systematic, cluster, or convenience). A group of test subjects is divided into twelve groups; then four of the groups are chosen at random.

over the argument its not good to fight.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

4+4+2x

or

2x+8
