Answer:

76

Step-by-step explanation:

median is the number in the very center of the list of numbers in order:

64, 72, 72, 80, 85, 89

to find the one in the middle we take away the numbers from both ends:

72, 72, 80, 85

72, 80

since there are two numbers in the middle we’ll find the average

(72+80)/2

152/2

76

Answer:

76

Step-by-step explanation:

Median means middle

so we are looking for the middle number

place the numbers in order and look for the number thats in the middle

64, 72, 72, 80, 85, 89

72 and 80 are both the middle numbers.

Therefore, we add 72+80 and then divide by 2

72+80= 152

152/2= 76

Final answer: 76 is the median

The parallelogram is reflected across the line y = x. Which of the following are coordinates of a vertex of the image?
Korvikt [17]

Answer:

A'(1,-5)

Step-by-step explanation:

The coordinates of the given quadrilaterals are

A(-5,1),B(-4,3),C(-2,1),D(-3,-1)


The reflection in the line y=x has the mapping,

(x,y)\rightarrow(y,x)


We just have to swap the coordinates.


This implies that,


A(-5,1)\rightarrow A'(1,-5)


B(-4,3)\rightarrow B'(3,-4)


C(-2,1)\rightarrow C'(1,-2)


D(-3,-1)\rightarrow D'(-1,-3)


Therefore the correct answer is A.

A'(1,-5)
