A study is done to compare the fuel efficiency of cars. The first group of cars generally get about 30 miles per gallon. The second group of cars generally get about 15 miles per gallon. Based on the mean values of each​ group, what inference can be​ made? What else might a person conclude from the mean​ values? Which of the following is a correct inference based on the mean​ values? A. The cars in group 1 and group 2 are  equally fuel efficient.
B. The cars in group 1 generally are m ore fuel efficient.
C. The cars in group 2 generally are m ore fuel efficient.​

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
