Answer:
The median is 72
Step-by-step explanation:
The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.
In this question:
Scores: 86, 67, 62, 82, 64 and 77
Sorted: 62, 64, 67, 77, 82, 86
Middle elements: 67 and 77
Median: (67 + 77)/2 = 72
The median is 72
These questions are no problem, so long as you remember the rules for rotations. A point that is rotated 90 counterclockwise is simply x and y flipped, and negating the y.
For example, 2,9 becomes -9, 2.
So point A would be -1, 1, B would be -2, 1. So on and so forth.
Answer:
B
