convert 22km/L to miles per gallon.
7. Miles-per-Gallon 6pts A car’s miles-per-gallon (MPG) can be calculated with the following formula: MPG = Miles driven / Gallons of gas used Design a program that asks the user for the number of miles driven and the gallons of gas used. It should calculate the car’s miles-per-gallon and display the result on the screen.Draw a flowchart in algorithmic language
Based on tests of the Chevrolet Cobalt, engineers have found that the miles per gallon in highway driving are normally distributed, with a mean of 32 miles per gallon and a standard deviation of 3.5 miles per gallon. a) If 25 cobalts are randomly selected, how many will have less than 30 miles per gallon? b) How many miles per gallon determine the 3rd quartile? c) 20 cobalts are randomly selecred and the miles per gallon for each car are...
The gas mileages (in miles per gallon) for 22 cars are shown in the frequency distribution. Approximate the mean of the frequency distribution.
You currently drive 375 miles per week in a car that gets 18 miles per gallon of gas. You are considering buying a new fuel-efficient car for$15,000(after trade-in on your current car) that gets 45 miles per gallon. Insurance premiums for the new and old car are$1000 and $500 per year, respectively. You anticipate spending $1500 per year on repairs for the old car and having no repairs on the new car. Assume gas costs$3.50 per gallon. Over a five-year...
The miles per gallon ratings for 2001 model year vehicles vary according to an approximately Normal distribution with mean ? = 20.23 miles per gallon and standard deviation ? = 6.10 miles per gallon. (a) What percent of vehicles have miles per gallon ratings greater than 28? (b) What percent of vehicles have miles per gallon ratings between 28 and 31? (c) What percent of vehicles have miles per gallon ratings less than 12.55?
If a car has an EPA mileage rating of 30 miles per gallon what is the rating in kilometers per liter? 1 L = 1.06 qt)
Suppose that gasoline costs $3.55 per gallon. Your car gets 35 miles per gallon. How many gallons of gas do you need to drive 455 miles? How much will gasoline cost to drive 1000 miles? How many miles can you drive on 19 gallons of gas? How far can you drive on $15 worth of gas?
The following data represent the miles per gallon for a particular make and model car for six randomly selected vehicles. Compute the mean, median, and mode miles per gallon. 23.8,37.3,36.7,32.7,31.7,34.8 Compute the mean miles per gallon. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
2) In order to develop a confidence interval for the average miles per gallon (MPG) for a brand of hybrid car, a simple random sample of 97 cars is selected from the population of 10,000 cars manufactured. The 97 cars had a sample mean MPG of 51.9 MPG and a sample standard deviation of 4.5 MPG. (6 points) a) Compute a 99% confidence interval for the average miles per gallon (MPG) for this brand of car. b) Imagine that an...
A department of transportation's study on driving speed and miles per gallon for midsize automobiles resulted in the following data: Speed (Miles per Hour) 30 50 40 55 30 24 60 24 51 56 Miles per Gallon 28 24 24 22 30 33 21 Compute the sample correlation coefficient (to 2 decimals and enter negative value as negative number). 35 26 24 What can you conclude, based on your computation of the sample correlation coefficient? - Select your answer -...
