6. No, the conclusions wrong because 20 out of 50 peoples favourite is drawing which means 20/50 which equals 0.4 times 100 which is 40% not 60%
7. Yes, the conclusion is right because 5/50 is equal to 0.1 times 100 which is 10%

Answer:
(x − 5)² + (y − 4)² = 4²
(x − 5)² + (y + 4)² = 4²
Step-by-step explanation:
x=1 and x=9 are vertical lines. If both are tangent to the circle, then the circle has a diameter of 8, or a radius of 4, and the center of the circle is on the line x=5.
y=0 is the x-axis. Since the circle is tangent to that, the center of the circle is either 4 units above the x-axis or 4 units below.
So two possible equations of the circle are:
(x − 5)² + (y − 4)² = 4²
(x − 5)² + (y + 4)² = 4²
