Since the whole set is composed of a total of 55 people, with 45 people being drinks of either coffer or tea, then the remaining people not included in the 45 would be the non-drinkers. So 55-45, meaning there are 10 people who drink neither tea nor coffee. To obtain the probability:
10/55 = 2/11 = 0.182
Therefore, the probability of a person being picked at random does not drink either coffee or tea is 0.182.
Y^2 - 7y + 6 = 0
(y - 1)(y - 6) = 0
y - 1 = 0
y = 1
y - 6 = 0
y = 6
so y = 1 or y = 6
The answer is 3200.
100 * 32 = 3200, basically just multiply it and add the two zeros from 100 and add them to 32 and u get 3200.
The range of the piecewise function would be from [2,infinity), or the second choice.
