Answer

Explanation:

Step1: Recall joint - relative frequency formula

Joint relative frequency = $\frac{\text{Frequency of the cell}}{\text{Total number of data points}}$

Step2: Identify relevant values

The frequency of teachers who teach math and not English is 22. The total number of teachers surveyed is 104.

Step3: Calculate joint - relative frequency

Joint relative frequency = $\frac{22}{104}\approx 0.2115$

Step4: Convert to percentage

$0.2115\times100 = 21.15%$. Rounding to the nearest percent gives 21%.

Answer:

21%
