- The fuel consumption of a car travelling at a speed of 72 km/h is approximately 10 L.
- The speed of a car that has a fuel consumption of 12 km/L is approximately 85 km/h
- The coldest day was July 7th.
- The hottest day was July 19th.
- There does not appear to be a change in temperature on July 1stand 2nd, July 10thand 11th, July 17th
and 18th. - Seattle
- Both cities appear to have rising temperature as the month progresses, but Seattle seems to have more
hot days and on the 20th, the temperature is still rising. The temperature in New York seemed to rise on
the 19thbut on the 20ththe temperature appears to drop off. - There appears to be a difference of approximately 10 degrees between the temperatures of the cities
- The first graph is labeled correctly as being continuous data. The amount of fuel remaining in your gas tank is
plotted for each hour you drive. However, the amount of fuel in your gas tank decreases every minute/second
you drive. All values on the graph are meaningful and therefore can be joined. This is continuous data. The
second graph is also labeled correctly as being discrete data. The cost of CDs is plotted for each CD you
purchase. The cost to you changes only when another CD is purchased. The values between the plotted points
are not meaningful and therefore are not joined. This is discrete data.
