Fuel economy estimates for automobiles built one year predicted a mean of 26.5 mpg and a standard deviation of 8.31 mpg for highway driving. assuming the gas mileages for automobiles are normally distributed, use the empirical rule to answer the following: the middle 99.7% of automobiles can be expected to have gas mileages between and . approximately % of automobiles will have a gas mileage more than 34.81 mpg. approximately % of automobiles will have gas mileages between 34.81 and 43.12. which of the statements below describes the gas mileages of the best 2.5% of cars? they get less than 1.57 mpg. they get more than 43.12 mpg. they get less than 9.88 mpg. they get more than 51.43 mpg.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
