I think this is geometry. So you would have to use the standard equation of a circle.
The standard equation of a circle with center (h,k) and a radius of r is: (x-h)^2 + (y-k)^2 = r^2
With that equation, we know that the center of YOUR equation is (3 , 2).
So now make (x-3) and (y-2) equal to 0.
That would make x=3 and y=2.
Therefore the answer is A.
Answer: 11. Is A
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
