Answer:
√63
Step-by-step explanation:
a² + b² = c²
1²=1
8²= 64
now think what + 1 = 64
b= √63
b ≈ 7.94
Pythagorean theorem:
b² = c² - a²
b=√c²﹣a²
b= √ (8)² - (1)²
b=√ 64 - 1
C
400
Explanation:

Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).
