Answer:
The mean is 85.25
The medium is 86
The mode is 92
Step-by-step explanation:
The mean is all the numbers added divided by the number of values.
77 + 92 + 80 + 92 divided by 4
341 divided by 4 = 85.25
The median is the middle number
92 + 80 divided by 2
172 divided by 2 = 86
The mode is the number that occurs the most which is 92.

Answer:
Step-by-step explanation:
Given: In parallelogram DEFG,
DH = x + 1
HF = 3y
GH = 3x - 4
and HE = 5y + 1
Solution: Since, DH,HF, GH and HE represents the diagonals of the parallelogram and we know that the diagonals of the parallelogram bisect each other, therefore
x+1=3y (1)
3x-4=5y+1 (2)
Multiply equation (1) with 3 and then subtract equation (2) from it, we get
3x+3-3x+4=9y-5y-1
7=4y-1
y=2
Substituting the value of y=2 in equation (1), we get
x+1=3(2)
x=5
Therefore, the value of x and y are 5 and 2 respectively.
