The standard deviation of the set is 5.2
To find standard deviation, we take the square root of the variance.
The answer is 8300.
Divide 91300 by 11 you will get the answer.
Problem-solving is the act of defining trouble; figuring out the cause of the problem; figuring out, prioritizing, and choosing alternatives for an answer; and enforcing a solution.

Answer:x= 5/2 x= -1/2
Step-by-step explanation:
4(x-1)2-9
4(x2-2x+1) - 9
4x2 - 8x + 4 - 9
4x2 - 8x - 5
4x2 +2x - 10x - 5
2x(2x+1) - 5(2x+1)
(2x-5)(2x+1)
therefore, x= 5/2 x= -1/2
