12,9,12,11,10,18,7,19,13,19
Mean = 13 (Average)
Median = 12 (Middle)
Mode = 12, 19 (most common)
The answer would be a reason being sinangle= opposite/hypotenuse
if u shift ur phone and observe it is 12/13
Answer:

Explanation:
Let's begin writing down everything
(X×(-11)+5)×(-9)+X-55
Now we can multiply
-9(-11X+5)+X-55
99X-45+X-55
And so we get
100X-100
Factorize 100
100(x-1)
The answer is it’s 5 pie over 4
