PRACTICE QUESTIONS
1. Draw an XY grid like this
a) Label quadrant 1, 2, 3, 4
b) Label the x axis and the y axis.
c) Plot point A (5,5) B (5, -4) C ( -6, 2)
d) Connect points A, B, and C
e) What shape did you draw?
2. Draw another XY grid.
a) Draw square WXYZ at W(2, 2) X(4, 2) Y(4, 4) Z(2, 4)
b) Translate the entire shape 5 spaces down
c) Translate the new shape 6 spaces left
d) Rotate the new shape 90 degrees CCW around point Z
e) Reflect the new shape over the Y axis
3. Draw a bar graph. Give titles to the X axis and the Y axis. Use this data:
In 1920, Canada's population was seven million.
In 1930, Canada's population was eight million.
In 1940, Canada's population was nine million.
In 1950, Canada's population was fourteen million.
In 1960, Canada's population was sixteen million.
In 1970, Canada's population was nineteen million.
In 1980, Canada's population was twenty three million.
In 1990, Canada's population was twenty seven million.
In 2000, Canada's population was thirty one million.
In 2010, Canada's population was thirty three million.
a) What does this graph show?
b) Why to the bars keep getting taller?
c) What decade saw the biggest jump?
d) What could you predict the population for 2020 to be?
4. Here is the population of some large Canadian cities.
a) Round each number to the nearest million.
b) What is the mean?
c) What is the median?
d) What is the mode?
e) Of mean, median, and mode, which one is a good choice to show how big a typical Canadian city is?
f) Of mean, median, and mode, which one is not a good choice to show how big a typical Canadian city is?
