Answer:
the answers are <em>interquartile range</em> and <em>mean absolute deviation</em>
Step-by-step explanation:
Since they are the conjugates of each (9-a and 9+a are conjugates, or with any number replacing 9) , we multiply it by (9+i)/(9+i) to get (9+i)^2/(9-i^2)=(81+2i+i^2)/(9-(-1))=(81-1+2i)/(10)=80/10+2i/10=8+i/5. Conjugates work because they make i into i^2 (-1) without any of the sneaky i's in the middle!
Answer:
B and C are correct
Step-by-step explanation:
17/4 = 4.25
4 and 1/4 = 17/4
