Answer:
They should interview 1620 adults now.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level, 
is the standard deviation of the population and n is the size of the sample.
In this question:
z wont change, neither will
We want to increase n as such the margin of error is reduced to one third.
We have that the margin of error is inversely proportional to the square root of the size of the sample, which means that for the margin of error to be reduced to one third, the sample size has to be multiplied by 
. So
180*9 = 1620

Answer:
The farmer should expect to LOSE 10 pounds of soybeans per acre per year
Step-by-step explanation:
f(x)=-x^2 + 20x + 100
just find how many soybeans his land will yield (per acre) after 10 and 20 years:
After 10: 200 pounds of soybeans/acre
After 20: 100 pounds of soybeans/acre
Because 10 years have passed and they lost 100 pounds of soybean production per acre, the farmer should expect to lose 10 pounds of soybeans per acre per year (-10 pounds of soybeans per acre/year)
Of course not.
-- Take a washable marker, and give your little sister another washable marker.
-- Stand back-to-back in your bedroom, you facing the front wall, and her facing the back wall.
-- When you say 'GO', both of you draw a straight line on the wall.
Then look at the lines.
-- The front and back walls are parallel planes, but it would be
amazing if the two lines are parallel. One could even be a
horizontal line and the other a vertical one . . . definitely not parallel.
