What proportion of students did not have a job in 1990?
The total number of students in 1990 = 155 + 125 + 1475 +1610 = 3365
The total number of unemployed in 1990 = 155 + 125 = 280
The percentage of students unemployed in 1990 = (280 / 3365) x 100 = 8.3%
What distinguished the graduates' group with the highest and lowest unemployment rates?
The unemployment rate for each group of graduates = (number of unemployed /
total number of students) x 100
Unemployment rate for 1990 private university graduates = (155 / (155+1475)) x
100 = 9.5%
Unemployment rate for 1990 state university graduates = (125 / (125 + 1610)) x
100 = 7.2%
Unemployment rate for 2000 private university graduates = (125 / (125 + 1350)) x
100 = 8.5%
Unemployment rate for 2000 state university graduates = (150 / (150 + 1250)) x
100 = 10.7%
The difference between the highest unemployment rate (2000 state university)
and the lowest unemployment rate (1990 state university) = 10.7-7.2 = 3.5%
In 1990, how many more people were employed than in 2000?
The number of employed in 2000 = Private + State = 1250 + 1350 = 2600.
The number of employed in 1990 = Private + State = 1475 + 1610 = 3085
The difference in the number of employed in 1990 and 2000 = 3085 -2600 = 485.
What percentage of travelers using Royal Air Services took Royal Baby Airlines in 2010?
The total number of passengers travelling with Royal Air Services in 2010 was
1,542,000 + 985,000 = 2,527,000. For the sake of simplicity, you could omit the thousands from the calculation since the question asks for proportions rather than absolute numbers.
The percentage of travelers flying with Royal Baby Airlines = (the number of passengers using Royal Baby Airlines / amount of passengers using Royal Air Services) x 100 = (985 / 2527) = 38.98% which is approximately 40%.
In 2012, what percentage of total ticket sales was Royal Baby Airlines responsible for?
The number of tickets sold by Royal Baby Airlines in 2012 was 1750000.
The overall number of tickets sold by Royal Air Services in 2012 = 1750000 +1995000 = 3745000.
The percentage of tickets sold by Royal Baby Airlines in 2012 was (1750000 / 3745000) x 100 = 46.73% ≈ 47%.
Wood, electricity, and kerosene were among the various energy sources once used to power home heating systems. However, in contrast to a more modern source, solar energy, these are more costly. Although there are some alternatives, only a few appliances can use solar energy for heating. Additionally, since the sun is the primary source of solar energy and it is most needed during the winter, it can be challenging to obtain solar energy for heating purposes.
Question: Winter is when solar energy is least available.
The text states that because the sun isn't as active in the winter, solar energy isn't really available during that season.
It is anticipated that both Royal Airlines and Royal Baby Airlines will sell 10% more tickets in 2015 than they did in 2009. The typical cost of a Royal Baby Airlines ticket is £75, while the typical cost of a Royal Airlines ticket is £232. What are Royal Air Services' anticipated ticket sales revenues for 2015?
In 2009, Royal Airlines sold 2005000 tickets.
The number of tickets each airline is expected to sell in 2015 is 2005000 x 1.1 = 2205500.
The combined revenues in 2015 from ticket sales is = (2205500 x 75) + (2205500 x 232) = 677088500 ≈ £677 million
