Yes 2 i agree with the question
I'm sorry, I didn't fully understand your question, but if it is What is the percent of liberal in State B the answer is 60%
x% * 35 = 21
x/100 * 35 = 21
35x/100 = 21
35x = 2100
x = 2100/35
x = 60
or 60 %
Rate of change is Rise over run=3/36=1/12 inches
The probability that the seed will produce a plant is almost certain at 90%
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
