The goals scored by 4 players in a season of soccer were recorded in the graph below.
Simon scored 6 goals in the season.
Gigi scored 3 goals.
How many more goals did Henry score than Fiona? (2 marks)
--- 2 WORK AREA LINES (style=lined) ---
\(7\ \text{goals}\)
\(\text{Since Simon scored 6 goals}\)
\(\longrightarrow\ \text{1 soccer ball = 2 goals}\)
\(\longrightarrow\ \text{Henry scored 8 goals.}\)
\(\longrightarrow\ \text{Fiona scored 1 goals.}\)
\(\therefore\ \text{Extra goals}\) | \(=8-1\) |
\(=7\ \text{goals}\) |
The picture graph shows how many tonnes of concrete are needed for 4 jobs.
How many more tonnes of concrete does Job 1 need than Job 3? (2 marks)
--- 2 WORK AREA LINES (style=lined) ---
\(2\ \text{tonnes}\)
\(\text{Job 1 needs 9 tonnes}\)
\(\text{Job 2 needs 7 tonnes}\)
\(\therefore\ \text{Extra tonnes}\) | \(=9-7\) |
\(=2\ \text{tonnes}\) |
The bottles in Leisa's fridge are pictured below.
Leisa decides to make a graph where each bar represents one type of bottle in her fridge.
Leisa makes an error when creating the graph.
What should Leisa do to correct the error?
\(D\)
\(\text{Remove the ‘Water’ category since tonic water and}\)
\(\text{soda water are already shown.}\)
\(\Rightarrow D\)
During picking season, four groups of people were hired to pick apples.
A group will receive a bonus if they pick more than 24 apples per person in a 10-minute period.
The table below shows the total amount of apples picked by each group in the first 10 minutes.
Which group would have received a bonus in the first 10-minute period?
\(C\)
\(\text{Calculate apples picked per person (in 10 mins) for each group:}\)
\(\text{A} = 68\ ÷\ 3=22.67\dots\)
\(\text{B} = 95\ ÷\ 4 = 23.75\)
\(\text{C} = 122\ ÷\ 5 = 24.4\)
\(\text{D} = 143\ ÷\ 6 = 23.83\dots\)
\(\Rightarrow C\)
Chris did a survey of the number of female toilets in four shopping centres.
The results were recorded in the table below but the key has been left off the graph?
The total number of female toilets was 44.
How many toilets does | represent in the graph? |
\(B\)
\(\text{Total number of female symbols}\)
\(=5+4.5+5.5+7\)
\(=22\)
\(\therefore\ \text{The number of toilets one symbol represents}\)
\(=\dfrac{44}{22}\)
\(=2\)
\(\Rightarrow B\)
Clive and Alvin asked their friends how many books they had read in the past month.
Clive draws a picture graph to show the results for his friends.
Alvin draws a column graph to show the results for his friends.
How many more of Clive's friends read 3-4 books in the last month than Alvin's friends?
\(C\)
\(\text{Number of Clive’s friends}\)
\(=4\times 2\)
\(=8\)
\(\text{Number of Alvin’s friends}\)
\(=2\)
\(\therefore\ \text{6 more of Clive’s friends.}\)
\(\Rightarrow C\)
