Bonjour,
J'espère que vous allez bien. Je rencontre quelques difficultés avec un devoir de maths euro et je me demandais si vous pourriez m'aider à résoudre ce problème .
Merci d'avance pour votre aide.
Sujet :(niveau terminal)
PS: le graphique est en pièce jointe
The scatter graph shows the age of cars and the number of kilometers travelled.
1. Describe the relationship shown by this scatter graph.
2. The age and number of kilometers travelled by one of these cars look out of place.
a)What is the age of this car and how many kilometers has it travelled?
b)Give a possible reason why the results for this car are different from the rest of the cars.
3. We extract the former car from the set of data.
a)Use your calculator to find an equation of the line of best fit, giving the number y of kilometers travelled in terms of the age x of the car. Give your result to the nearest unit.
b)What could be the age of a car that has travelled 35000km? Give your result to 1dp.
c)What could be the mileage of a 6 year old car? Of a 10 year old car?
