Answer:
Not the same.
Step-by-step explanation:
Given that there is a rotation of 180 degrees . To check whether this is a reflection over the y axis.
Reflection over the y axis make the coordinates (x,y) as (-x,y)
i.e. this means rotation of 180 degrees about the origin anticlockwise.
Hence just rotation of 180 degrees is not the same as a reflection over y axis.
The conditions are:
i) 180 degree to be rotated anticlockwise
ii) Rotation is about the origin
Hence a rotation of 180 degrees need not always be the same as reflection over y axis.

Answer: The Median: 78, The First Quartile: 63, and The Third Quartile: 99
Step-by-step explanation: Ok, so let's put the data set from least to greatest....
(63, 63, 76,) (77, 79,) (84, 99, 99)
First Quartile Third Quartile
First, let's find the median, since you made a little mistake...
77 + 79 = 156
156 ÷ 2 = 78
The median is 78!
Now, let's determine the first quartile and the third quartile.
For the the first quartile/third quartile it'll be the middle number, if it's even we'll do the same extra step just like we'll do for the median. In this case it's not even therefore...
First Quartile: 63
Third Quartile: 99
I hope this helps!
