Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6

Answer:
Step-by-step explanation:
The monthly rents paid by the 10 people are
845, 875, 890,900,960, 965, 990, 1015, 1045, 1065.
The mean rent is determined by
Sum of rent paid/ total number of people that paid rent.
Mean = (845+875+890+900+960+965+990+1015+1045+1065) /10 = 9550/10 = 955
Median = (960+965)/2 =1925/2 = 962.5
Suppose that one of the people moves, her rent changes from 1065 to 915, the mean becomes
(845+875+890+900+ 915 + 960+965+990+1015+1045)/10 =9400/10 = 940
The median is (915 +960)/2 =1875/2 = 937.5
Therefore,
a) the mean decreases by
955 - 940 = 15
b) the median decreases by
962.5 - 937.5= 25
