The gas mileage for a certain vehicle can be approximated by m=-0.02x2 +3.9x - 49, where x is the speed of the vehicle in mph. Determine the speed(s) at which the car gets 30 mpg. Round to the nearest mph. Part 1 The car reached a gas mileage of 30 mpg twice Part 2The vehicle will get 30 mpg at speeds of approximately _______ mph and _______ mph .
Question 14 of 15 (1 point) Attempt of Unlimited View question in a DODUD 15 Section Exercise 36 The gas mileage for a certain vehicle can be approximated by m= -0.02x+3.9x - 49, where x is the speed of the vehicle in mph. Determine the speed(s) at which the car gets 25 mpg. Round to the nearest mph. Part 1 of 2 The car reached a gas mileage of 25 mpg twice Part: 1/2 Part 2 of 2 mph and...
Your used Chevy's gas mileage (in miles per gallon (mpg) is given as a function M (x) of speed in miles per hour (mph), where M(1) - 2000 Calculate M' (40), M' (50) and M' (60) rounded to two decimal places M' (40) = mpg/mph M' (50) = mpg/mph M' (60) = mpg/mph
The
equation M(x,y)=56+0.2x-0.8y gives the mileage (in mpg) are the new
car as the function of tire pressure x (in psi) and speed y (in
mph). Find M(36,42). (include the appropriate units) and explain
what it means.
The equation M(x,y) = 56 +0.2% - 0.8y gives the mileage (in mpg) of a new car as a function of tire pressure x (in psi) and speed y ſin mph). Find M(36,42) (include the appropriate units) and explain what it means. M[36,42)-01...
1.
This equation M(x,y)=61+0.6x-0.1y gives the mileage (in mpg) I have
a new car as a function of tire pressure x (in psi) and speed y (in
mph). find M(30,47) (include the appropriate units) and explain
what it means.
2. This equation M(x,y) 61+0.1x-0.4y gives the mileage (in
mpg) I have a new car as a function of tire pressure x (in psi) and
speed y (in mph). Find Mx(29,44) (include the appropriate units)
and explain what it means.

A certain model of automobile has its gas mileage (in miles per gallon, or mpg) normally distributed, with a mean of 26 mpg and a standard deviation of 4 mpg. Find the probability that a car selected at random has the following gas mileages. (Round your answers to four decimal places.) (a) less than 20 mpg (b) greater than 28 mpg (c) between 24 and 28 mpg
A company claims that you can expect your car to get one mpg better gas mileage while using their gasoline additive. A magazine did a study to find out how much a car’s gas mileage improved while using the gasoline additive. The study used 36 cars and recorded the average mpg with and without the additive for each car in the study. The cars with the additive averaged 1.20 mpg better than without and had a variance of 0.36 (mpg)2.a....
The fuel efficiency for a certain midsize car is given by E(V) = -0.018V2 + 1.620V + 3.7 where E(v) is the fuel efficiency in miles per gallon for a car traveling v miles per hour. (a) What speed will yield the maximum fuel efficiency? Round to the nearest mile per hour. mph (b) What is the maximum fuel efficiency for this car? Round to the nearest mile per gallon. mpg Need Help? Read It Watch It Talk to a...
