We know that the average score for the entire class is 70. We also know that there are 35 students in the class and 20 of them are male, leaving 15 female students. We can use these numbers to set up an equation:

(20 * 73 + 15 * x) / 35 = 70

Simplifying this equation, we get:

1460 + 15x = 2450
15x = 990
x = 66

Therefore, the average score for the 15 female students in the class is 66.
