If this question is not multiple choice, another point on the circle could be (1,6) because it is 5 units away from (1,1).
4(y= 1/2x -4)
4y = 2x -16
y= -2x -9
5y = -25
Y= -5
So since there is only one answer with y= -5 the answer is A

Answer:
b. 2.01 < σ < 2.81
Step-by-step explanation:
The 90% confidence interval for the population standard deviation is calculated as:
< σ < 
Where n is equal to 51, s is equal to 2.34, 
is 10%, 
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of 
in the right tail and 
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of 
in the right tail.
So, replacing n by 51, s by 2.34, by 67.50 and by 34.76, we get that the The 90% confidence interval is equal to:
< σ <
2.01 < σ < 2.81
