Step-by-step explanation7:
Simply the expression which is 30
<h3>Answer:</h3>
x=135°
<h3>Explanation:</h3>
All the internal angles of the octagon are angles of 135°
52=2*26=2*2*13
We can see that 52=2*2*13,
so 52 is divisible by 1, by 2, by 4, by 13, by 26 and by 52.
The z-score of the data can be calculated by the formula expressed as follows:
z = ( score - mean ) / standard deviation
z = (126 - 150 ) / 11 = <span>-2.18
</span>
A z-Score<span> is a statistical </span>measurement<span> of a </span>score's<span> relationship to the mean in a group of </span>scores<span>. A </span>Z-score<span> of 0 means the </span>score<span> is the same as the mean.</span><span>
