10(y+2)-y=2(9y-8)
Mutiply the first bracket by 10
Mutiply the second bracket by 2
(10)(y)(10)(2)= 10y+20
(2)(9y)(2)(-8)= 18y-16
10y+20-y= 18y-16
10y-y+20= 18y-16
9y+20= 18y-16
move 18y to the other side
sign changes from +18y to -18y
9y-18y+20= 18y-18y-16
-9y+20= -16
move +20 to the other side
sign changes from +20 to -20
-9y+20-20=-16-20
-9y= -36
divide by -9
-9y/-9= -36/-9
y= 4
Answer: y= 4

Step-by-step explanation:
Your most likely to land on tails because out of the 200 u landed on heads 14 times whereas u landed on tails 186 times since there's only two sides to a coin. there for you are more likely to land on tails than heads.
1. Mean.

2. <span>Standard deviation.
First we have to square each value and calculate the mean of that squares:

so the variance:

and the standard deviation:
