A) If you only sample people in a sports supply store, your sample will be biased. People in a sports supply store are more likely to be people that belong to a gym.
B) While it does not have necessarily the same amount of bias as sampling people in the sports supply store, people that go to a park are generally more likely to be people that exercise or have a gym membership.
C) Taking a random sample of people in town is a good way to get a non-biased sample. They are not necessarily predisposed to answer your question one way or another.
D) For the same reason as choice A, this is a biased sample.
C is the best choice.
Answer:
Sedan: 4 passengers
Minivan: 6 passengers
Step-by-step explanation:
We can write the following system of equations:
, where 
represents the number of people a sedan can seat and 
represents the number of people a minivan can seat.
Subtracting the first equation from the second, we have:
Now plug in 
in any of the equations to solve for :
Verify that the solution pair 
works:
Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
Answer:
Step-by-step explanation:
-5t ≥ 70
t ≤ -14
Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3
200 miles
$71-$35=$36 left in budget
$36/.18 per mile= 200 miles
