Answer:
a) 0.0255
b) 0.7050
c) 0.2945
Step-by-step explanation:
Probability that one of those sampled saying that Roosevelt was the best president since World War II = 330/2062 = 0.16
Probability that one of those sampled don't mention Roosevelt = (2062 - 330)/2062 = 1732/2062 = 0.84
a) The probability that both adults picked say Franklin Roosevelt was the best president since World War II = (330/2062) × (329/2061) = 0.0255
b) The probability that neither of the two adults say Franklin Roosevelt was the best president since World War II = (1732/2062) × (1731/2061) = 0.7050
c) The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = Probability that one of the two adults mention Roosevelt + Probability that the two adults mention Roosevelt
Probability that one of the adults mention Roosevelt = [(330/2062) × (1732/2061)] + [(1732/2062) × (330/2061)] = 0.269
Probability that two of the adults mention Roosevelt has been done in (a) and it is equal to 0.0255
probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = 0.269 + 0.0255 = 0.2945

Answer: Ok so I'm not sure what your question is but if you are looking for y then the answer is y= 3 - x, if you are looking for x then the answer is x = 3 - y.
The answer is c because you need to multiply both numbers inside the parentheses by the number on the outside
Given:
Line
To find:
Slope of the perpendicular line and slope of the parallel line.
Solution:
Equation of a given line:
Subtract 8x on both sides, we get
Divide by -6 on both sides.
Slope of this line is .
If two lines are perpendicular then their slopes are negative inverse of one another.
Slope of perpendicular line =
If two lines are parallel, then their slopes are equal.
Slope of perpendicular line =
