Rose Harrison and Clara Huizink Solutions for Exercise 5: Practice 2

Here are the numbers of croissants a baker sold each day during a three-week period:

$35,47,34,46,62,41,35,47,51,59,56,73,38,41,44,51,45,60,25,35,46$

Construct an ordered stem-and-leaf diagram to represent the data.

The masses (in grams) of $11$ Chinese striped hamsters are:

$21.6,22,4,27.2,30.5,25.2,23.1,25.3,21.3,20.9,24.5,25.2$

Construct an ordered stem-and-leaf diagram to represent the data.

The stem-and-leaf diagram shows the distances in kilometres students in one class travel to school.

$$\begin{gathered} \begin{array}{llllll}0& 4& 6& 6& 7& \\ 1& 2& 3& 3& 3& 8\\ 2& 0& 2& 6& 9& \\ 3& 1& 1& 2& 7& \\ 4& 0& & & & \end{array} \\ \text{ Key: }2\mid 0\text{ represents }20 \mathrm{km} \end{gathered}$$

If the least distance travelled is $d \mathrm{km}$, then find the value of $d$.

The stem-and-leaf diagram shows the distances in kilometres students in one class travel to school.

$$\begin{gathered} \begin{array}{llllll}0& 4& 6& 6& 7& \\ 1& 2& 3& 3& 3& 8\\ 2& 0& 2& 6& 9& \\ 3& 1& 1& 2& 7& \\ 4& 0& & & & \end{array} \\ \text{ Key: }2\mid 0\text{ represents }20 \mathrm{km} \end{gathered}$$

If the greatest distance travelled is $x \mathrm{km}$, then find the value of $x$.

The stem-and-leaf diagram shows the distances in kilometres students in one class travel to school.

$$\begin{gathered} \begin{array}{llllll}0& 4& 6& 6& 7& \\ 1& 2& 3& 3& 3& 8\\ 2& 0& 2& 6& 9& \\ 3& 1& 1& 2& 7& \\ 4& 0& & & & \end{array} \\ \text{ Key: }2\mid 0\text{ represents }20 \mathrm{km} \end{gathered}$$

Find the number of students in the class.

The stem-and-leaf diagram shows the distances in kilometres students in one class travel to school.

$$\begin{gathered} \begin{array}{llllll}0& 4& 6& 6& 7& \\ 1& 2& 3& 3& 3& 8\\ 2& 0& 2& 6& 9& \\ 3& 1& 1& 2& 7& \\ 4& 0& & & & \end{array} \\ \text{ Key: }2\mid 0\text{ represents }20 \mathrm{km} \end{gathered}$$

Write down how many students travel $13\mathrm{km}$

The stem-and-leaf diagram shows the distances in kilometres students in one class travel to school.

$$\begin{gathered} \begin{array}{llllll}0& 4& 6& 6& 7& \\ 1& 2& 3& 3& 3& 8\\ 2& 0& 2& 6& 9& \\ 3& 1& 1& 2& 7& \\ 4& 0& & & & \end{array} \\ \text{ Key: }2\mid 0\text{ represents }20 \mathrm{km} \end{gathered}$$

Students who travel more than $18\mathrm{km}$ get cheaper bus fares. Find the percentage of students who get cheaper bus fares.

Here are the heights of one-year-old apple trees in centimetres

$\begin{array}{lllllllll}180& 184& 195& 177& 175& 173& 169& 167& 197\\ 173& 166& 183& 161& 195& 177& 192& 161& 166\end{array}$

Organise and represent the data in a stem-and-leaf diagram.
