Acircle is represented by the equation below: (x + 2)2 + (y − 4)2 = 225
which statement is true?
(a)the circle is centered at (−2, 4) and has a radius of 15.
(b)the circle is centered at (2, −4) and has a diameter of 15.
(c)the circle is centered at (2, −4) and has a radius of 15.
(d)the circle is centered at (−2, 4) and has a diameter of 15.

wow ok so the answer is 1k or just k

because of combining like terms xd

answer: the answer is   graph (a)

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.

y = -1

x = 8

hope this !
