First you find the median, the middle term (if there are an even number of terms it is the average of the middle two terms.) Since you have 21 terms, odd, you just use the middle term, in this case 8. The first quartile works the same way, but just on the left half between the start and the median...so the first quartile is 6.
Square root of 256 is 16
Square root of 625 is 25
Square root of 121 is 11
OK I will answer give me a few minutes I’ll try to be fast and come back to you in the comment section
AB= 3x+4 + 5x-6 = 8x-2
the others are just what they are given as
30 = arc BC / 2
arc BC = 2(30)
arc BC = 60
answer
D. 60
