Question

1. 5\frac{2}{3}\cdot\frac{1}{2}=
2. \frac{2}{3}\div\frac{1}{2}=
3. use the box plot below to answer the following question: what is the interquartile range?

Explanation:

Step1: Recall inter - quartile range formula

The inter - quartile range (IQR) is $Q_3 - Q_1$, where $Q_3$ is the third - quartile and $Q_1$ is the first - quartile.

Step2: Identify $Q_1$ and $Q_3$ from box - plot

From the box - plot, $Q_1$ is the value at the left - hand side of the box. Here, $Q_1 = 20$. $Q_3$ is the value at the right - hand side of the box. Here, $Q_3 = 40$.

Step3: Calculate the IQR

$IQR=Q_3 - Q_1=40 - 20 = 20$.

Answer:

20
