Answer:
(a) .55
(b) .08
(c) about 42681 people
Step-by-step explanation:
Statistics!!
(a) .55 = point estimate
The point estimate is the middle of those two values, or the average. (.63+.47) / 2 = .55.
(b) .08 = ME
The margin of error is the difference between the point estimate and the outer values of the interval. .63-.55 = .08
(c) 42681 people
We think that .55 of the population want to add the bike lanes, so .55 * 75783 = 41680.65 ≈ 42681
To answer the question above, let x be the shorter one of the pieces. With the variable, we can express the longer piece as 2x + 3. Based on the given, the sum of the lengths of these pieces should sum up to 14 ft.
2x + 3 + x = 14 ft, x = 3 2/3 ft
Substituting this value for the longer piece, we get 10 1/3 ft. Thus, the lengths of the pieces are 3 2/3 ft and 10 1/3 ft.
