If (x + 2)2 + (y − 5)2 = 25 is the equation of a circle, which statement describes the circle's graph?
A) The center of the circle is (2, 5), and the circle's radius is 25.
B) The center of the circle is (−2, 5), and the circle's radius is 5.
C) The center of the circle is (2, −5), and the circle's radius is 5.
D) The center of the circle is (−2, −5), and the circle's radius is 5.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

1) is right
