To find the median of the numbers in the image, let's follow these steps:

1. List the numbers:
   The numbers are 7, 4, 8, 9, 5, and 4.

2. Arrange them in ascending order:
   $4, 4, 5, 7, 8, 9$.

3. Identify the middle numbers:
   Since there are 6 numbers (an even count), the median is the average of the two middle numbers. These are the 3rd and 4th numbers: $5$ and $7$.

4. Calculate the median:
   Median = $\frac{5 + 7}{2} = \frac{12}{2} = 6$.

Answer: The median of these numbers is 6.
