Which pair represents the same complex number?
lorasvet [3.4K]
For this case we have the following complex number:
 1 + i
 Its equivalent pair is given by:
 root (2) * (cos (pi / 4) + i * sin (pi / 4))
 Rewriting we have:
 root (2) * (root (2) / 2 + i * (root (2) / 2))
 (2/2 + i * (2/2))
 (1 + i)
 Answer:
 
option A represents a pair with the same complex number

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 7, 18, 18, 15, 17, 10, 1
Serhud [2]

Answer:

Mean= 13.38

Median= 15

Step-by-step explanation:

The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students

Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8

= 107/8

= 13.38

The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers

7 , 7, 10, 15, 15, 17, 18, 18

Median = 15+15/2

= 30/2

= 15

Hence the mean is 13.38 and the median is 15
