It was said that the question was answered before but I didn't get any answers. please send all answers.

Question 1: Which car manufacturer has the greatest number of car models (carline)? Consider variations as separate models. For instance, BMW 228i and BMW 228i xDrive, are different models. (HINT: Use Count in Measure and Sort.) Question 2: a) Which car manufacturer has the highest average fuel economy for city driving?? b) Which car manufacturer has the highest average fuel economy for highway driving?? (Question 3: Which car model has, on average, the greatest difference between its highway fuel economy and its city fuel economy? (HINT: Create a calculated field that subtracts city fuel economy from highway fuel economy.) Question 4: What is the relationship between combined fuel economy and engine power (engine displacement)? (i.e., when an engine becomes more powerful,, what happens to fuel economy ?) Question 5: a) Which transmission type has the best average combined fuel economy? b) Which transmission type has the worst average combined fuel economy? (Hint: Use the "Transmission Description" dimension.) Question 6: Which manufacturers produce small four-wheel drive (4WD) SUVs and small 2WD SUVS whose average engine displacement (engine power) is greater than 3.0? (HINTS: Use a filter with the "Carline Class Desc" dimension to show small 4WD and small 2WD only! Also use a filter to hide average Engine Displacement that is less than 3.0.) Question 7: a) What is the relationship between city fuel economy and highway fuel economy? b) What is the one car model with the lowest city and the lowest highway fuel economy? (HINT: To find it is required to put labels with the car model names. an answer, od to go
