( 7 + 3i ) - ( 2 + 3i )
= 7 - 2 + 3i - 3i don't forget the adjictive inverse which is 3i - 3i = 0

Answer:
Step-by-step explanation:
13.71
Step-by-step explanation:
Given the data as : 13 , 17, 9, 21
Finding the mean of the data;
sum of data set =13+17+9+21=60
Number of data set ,n,= 4
Mean= sum/n =60/4 =15
Finding the deviation from the mean
13-4=9
17-4=13
9-4=5
21-4=17
Squaring the deviations from mean
9²=81
13²=169
5²=25
17²=289
Adding the squares of deviations from the mean
81+169+25+289 =564
Finding n-1
4-1=3
Finding variance
564/3 =188
Finding the standard deviation
√188 = 13.71
You can use the numbers -10 and -270. When you multiply two negatives it turns to positive so this will work.
-10•-27=270
-10+(-27)= -37
