Mean: Add all the numbers and divide by the amount of numbers.
20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)
Mean = 9.889 (rounded)
Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25
The middle number is 7
Median = 7
Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers
Range: Subtract the greatest number with least number
25 - 0 = 25
Range = 25

Answer:
(x, y) → (–x, –y)
Step-by-step explanation:
The rule for 180° rotation about the origin is

The coordinates of the image are obtained by negating both the x and y coordinates of the preimage.
Whether the rotation is clockwise or counterclockwise, the rule remains the same.
The correct option is (x, y) → (–x, –y)
Answer:
This is a complicated problem
Step-by-step explanation:
it's called collatz conjecture and well is just unsolved problems
