Answer:
x² + y² = 6.25
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.
From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so
( x – 0)² + ( y - 0)² = (2.5)²
x² + y² = (2.5)²
x² + y² = 6.25

Answer:
D
Step-by-step explanation:
A margin of error provides information on the percentage points ones results will differ from the real value.
If margin of error is 3% and estimated value is 6%, it means that the confidence interval would be within ±3 of the estimated value.
So, the confidence interval would be between 3% (6% - 3%) and 9% (6% + 3%)
