11' For an agricultural experiment, 300 seeds were planted in one plot and 200 were planted in a second plot. If exactly 25 percent of the seeds in the first plot germinated and exactly 35% of the seeds in the second plot germinated, what percent of the total number of seeds germinated? (300*0.25+200*0.35)/500 = 29%
