<span>Work out the Mean (the simple average of the numbers)Then for each number: subtract the Mean and square the result.Then work out the mean of those squared differences.<span>Take the square root of that and we are done!</span></span>
You only need to look at the y intercepts.
-11 - -7 is -4, but you can't have a negative distance so it's just 4
all "atomic" or constituent statements are true
at least one "atomic" or constituent statement is true
The answer would be 10.
6 + 5 = 11
11 x 9 = 99
This means 9(6+5) = 99
99 - 89 = 10
