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

Answer:
- 32
- 400
Step-by-step explanation:
Lets start by defining the numbers in the equation.
This equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same
In slope-intercept form,
- m = slope or rate
- and b = y-intercept
Th equation is y=400+32x so now we know
For the first question the change per minute is the rate so it is <u>32.</u>
For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>
