The sample is not randomly chosen. if you call every tenth person in a sample of 40 people
then you have 10, 20, 30, 40
and your sample is 4 people
that seems pretty small. I hope this helps :) . Have a nice day!
Answer:
2x - 4
Step-by-step explanation:
x + 10 + x - 14
2x + 10 - 14
2x - 4
It would be 2.1 hours or about 2 hours.
It says the train travels about 2118 miles per 8 miles. So, divide 2118 by 8, which gives you 264.75 (when you see the word PER it usually indicates to divide). That gives you part A.
Then, you divide 560, (which is t<span>he distance between Columbus, Ohio, and New York) by 264.75 to see how many hours it took, which gives you 2.1152030217...., which simplifies to 2.1. Which gives you the answer for B.
So,
A is 560 and
B is 2.1 or 2
