The answer should be:
y=3.5x-2.1
Answer:
V = 27.4 in^2
Step-by-step explanation:
Converting to mixed numbers with fractions in decimal format makes this problem easier. 2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.
The volume formula is V = L*W*H.
Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
