(-i+5)(1-5i) simplify using step by step. -for carnegie learning.

First you had to used their apply complex arithmetic rule.

Then you had to refine by equation.

Finally, refine again by equation.

Final

Hope this helps!

And thank you for posting your question at here on , and have a great day.

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.
