We are being informed that 9% of the people said turkey; &
7/100 said mashed potatoes.
The percentage of people that chose mashed potatoes = 7%
This implies that, in the given survey, the percentage of people who chose turkey is quite higher than those who chose mashed potatoes which makes turkey to be more popular.
It has to do with the unit circle, I think it is A because it should be 2(0+ (-1)) but I would probably wait for someone to come behind me and explain it better sorry couldn't help more
