Answer:
Least common multiple (LCM) of 5 and 10 is 10.
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>

True.
Because, OAC forms a triangle where:
- the base is AC,
- the other two sides are OA and OC with same length equal to OP (the radius of the circle)
- when you trace the bisectriz of AC you realize it is a line perpedicular to AC that intersects the center of the the circle, O
