There would be 14 female and 7 male, so the total number of students is 21.
Answer:
x = 14
Step-by-step explanation:
![f(x) = 10 - \frac{9}{2} x \\ \\ plug \: f(x) = - 53 \\ \\ - 53 = 10 - \frac{9}{2} x \\ \\ \frac{9}{2} x = 10 + 53 \\ \\ \frac{9}{2} x = 63 \\ \\ x = 63 \times \frac{2}{9} \\ \\ x = 7 \times 2 \\ \\ x = 14](https://tex.z-dn.net/?f=f%28x%29%20%3D%2010%20-%20%20%5Cfrac%7B9%7D%7B2%7D%20x%20%5C%5C%20%20%5C%5C%20plug%20%5C%3A%20f%28x%29%20%3D%20%20-%2053%20%5C%5C%20%20%5C%5C%20%20-%2053%20%3D%2010%20-%20%20%5Cfrac%7B9%7D%7B2%7D%20x%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B9%7D%7B2%7D%20x%20%20%3D%2010%20%2B%2053%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B9%7D%7B2%7D%20x%20%20%3D%2063%20%5C%5C%20%20%5C%5C%20x%20%3D%2063%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B9%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%207%20%5Ctimes%202%20%5C%5C%20%20%5C%5C%20x%20%3D%2014)

Option D: 14 is the right answer
Step-by-step explanation:
In order to find the value of given expression we have to put the given value for f in the expression
Given expression is:
![f^2+5](https://tex.z-dn.net/?f=f%5E2%2B5)
We have to find the value of expression on f=3
So,
putting f=3 in expression
![= (3)^2+5\\= 9+5\\=14](https://tex.z-dn.net/?f=%3D%20%283%29%5E2%2B5%5C%5C%3D%209%2B5%5C%5C%3D14)
The value of given expression at f=3 is 14
Hence,
Option D: 14 is the right answer
