Answer:
Divide them both by 100
Step-by-step explanation:
75, 76, 80, 83, 84, 85, 89, 91, 94, 94
The median is 84.5
You add the two middle numbers (84, 85) and divide by 2.
The problem in the picture would be
x^2+10x+21
A squared + b squared = c squared
8.6^2+14.7^2=c^2
73.96+216.09=c^2
square root both sides and...
c=17.03085
Your answer is A
