Answer:
WZY=170°
XYZ=60°
Step-by-step explanation:
Straight line, so WZY=180-10=170
Angles in a quadrilateral add to 360°, so:
100+30+170=300
360-300=60
XYZ=60°

when the degree of the numerator is greater than the denominator's, then it has no horizontal asymptotes.
quick note:
when the degree of the numerator is 1 higher than the degree of the denominator, then it has an slant-asymptote, so this one has a slant-asymptote.

Answer:
7.9
Step-by-step explanation:
Mean=sum of observations/no. Of observations
Mean=(12+7+12+9+2+15+6+6+6+1+11)/11
Mean=87/11
Mean=7.9
