Based on data from 1990 to 2000, the retail cost of unleaded regular gasoline can be modeled by
R(t) = 0.035t + 1.16 dollars per gallon
and the retail cost of unleaded premium gasoline can be modeled by
P(t) = 0.034t + 1.35 dollars per gallon
where t is the number of years after 1990.†
(a) Solve the system of equations algebraically.
(t, P(t)) =

Explain what your solution means.
Our models predict that
years after 1990 the price per gallon for regular unleaded and premium unleaded will be the same price: $
per gallon.

(b) Based on your experience of purchasing gasoline, does your solution seem reasonable?
Yes
No

If you answer right ill give brainliest, : )

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
