The graph below shows the amounts of waste produced by three companies over a period of 15 years.
The line graph shows three companies in terms of their waste production between the years 2000 and 2015.
Overall, there were significant changes in the amounts of waste output by all three companies shown on the graph. While companies A and B saw waste output decrease over the 15-year period, the amount of waste produced by company C increased considerably.
In 2000, company A produced 12 tonnes of waste, while companies B and C produced around 8 tonnes and 4 tonnes of waste material respectively. Over the next 5 years, the waste output of companies B and C went up by around 2 tonnes, but the figure for company A went down by approximately 1 tonne.
From 2005 to 2015, company A cut waste output by roughly 3 tonnes, and company B reduced its waste by around 7 tonnes. By contrast, company C saw an increase in waste production of approximately 4 tonnes over the same 10-year period. By 2015, company C’s waste output had increased to 10 tonnes, while the respective amounts of waste from companies A and B had decreased to 8 tonnes and only 3 tonnes.
The charts below show the results of a questionnaire that asked visitors to the Parkway Hotel how they rated the hotel's customer service. The same questionnaire was given to 100 guests in the years 2005 and 2010.
The pie charts show the visitors’ responses to a survey about customer service at the Parkway Hotel in 2005 and in 2010.
It can be seen that overall customer satisfaction increased considerably from 2005 to 2010. While most hotel guests rated customer service as satisfactory or poor in 2005, most of them described the hotel’s service as good or excellent in 2010.
If you look at the positive responses first, in 2005 only 5% of the hotel’s visitors rated its customer service as excellent, but this figure rose to 28% in 2010. Furthermore, while only 14% of guests described customer service in the hotel as good in 2005, almost three times as many people gave this rating five years later.
Looking at the negative feedback, the proportion of guests who considered the hotel’s customer service to be poor fell from 21% in 2005 to only 12% in 2010. Similarly, the proportion of people who thought customer service was very poor dropped from 15% to only 4% over the 5-year period. Finally, a fall in the number of ‘satisfactory’ ratings in 2010 proves that more people gave positive responses to the survey in that year.
The chart below shows the total number of Olympic medals won by twelve different countries.
The bar chart illustrates the overall number of medals won by different countries at the Olympic Games.
Overall, USA is by far the most successful Olympic medal winning nation. Furthermore, figures for gold, silver and bronze medals won by any particular country tend to be fairly similar.
In first place, the USA has won a total of around 2,300 Olympic medals, including approximately 900 gold medals, 750 silver and 650 bronze. In second place, the Soviet Union, has won over 1,000 medals. Again, the number of gold medals won by this country is slightly higher than the number of silver or bronze medals.
Other four countries - the UK, France, Germany and Italy - have won more than 500 Olympic medals, all with similar proportions of each medal colour. Apart from the USA and the Soviet Union, China is the only other country with a noticeably higher proportion of gold medals (about 200) compared to silver and bronze (about 100 each).
The diagram shows the life cycle of the honey bee.
nymph = immature form of an insect
moult = shed or lose old feathers, hair or skin to allow for new growth
The diagram shows the various stages in the life of honeybee. As is illustrated in the diagram the complete life cycle of honeybee lasts between 34 and 36 days. Overall, there are five main stages in the development of the honey bee, from egg to mature adult insect.
During the first stage of the life cycle, the female adult lays an egg; the female typically lays one or two eggs every 3 days. After this, between 9 and 10 days later, each egg hatches and the immature insect, or nymph, appears.
During the next stage of the life cycle, the nymph grows in size and sheds its skin three times. This moulting first takes place 5 days after the egg hatches, then 7 days later, and again another 9 days later. After a total of 30 to 31 days from the start of the cycle, the young adult honey bee emerges from its final moulting stage. This stage lasts for 4 days, and finally it reaches full maturity.
The table illustrates the percentages of people using different functions of their mobile phones between 2006 and 2010.
It is clear that in the given period, the main reason why people used their mobile phones was to make calls. However, there was a remarkable increase in the popularity of other mobile phone features, particularly the Internet search feature.
In 2006, mobile phone usage to make calls was 100%. while the popularity of text messaging was 73% and taking photos was 66%. Oppositely, less than 20% of owners played games or music on their phones, and there are no figures given for those who are surfing the internet or recording video.
Over the next 4 years, there was relatively a slight change in the figures for the top three mobile phone features. However, mobile web usage increased dramatically to 41% in 2008 and then to 73% in 2010. There was also a marked rise in the use of mobile games and to record video, with figures reaching 41% and 35% respectively in 2010.
