Answer:
34°
Step-by-step explanation:
The angle made when a tangent and a radius intersect=90°
Therefore angle OQP =90°
The triangle made by the two radii is isosceles ( base angles are equal) hence angle POQ=180-2(62)
=56°
The right triangle OPQ can hence be solved as follows
angle POQ=56°
angle OQP=90°
angle x=180-(56+90)=34° as all the interior angles of any triangle add up to 180°

I do not know the answer to this i suck at math
Answer:
a) The new correlation coefficient should be the same: R = 0.72
Step-by-step explanation:
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.
It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.
If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.
So the answer is
a) The new correlation coefficient should be the same: R = 0.72
