Answer:
(x - 2)(7x - 4)=0
Step-by-step explanation:

Find the standard deviation of the following data set. Assume the data set is a sample. 14,28,10,16,23,17,17,23,22,22,26
vlada-n [284]
5.43724529184 would be the standard deviation.
Answer:
a) and b) satisfied the condition of the given equation.
Step-by-step explanation:
Given:
≠
+ 
Then,
≠ 
a) For a = 21, b = 4 and c = -2, then we have;
≠ 
≠ 
≠ 
≠ 
Therefore the condition of the given equation is satisfied.
b) For a = 1, b = 10 and c = 1, then we have:
≠ 
≠ 
≠ 
Therefore the condition of the given equation is satisfied.
