4ax+12-3ax=25+3a
ax+12=25+3a
ax-3a=25-12
a(x-3)=13
198 round to the nearest hundreds is 200
198 round to the nearest tens is 200 too
The outlier (61) is at the low end of the data set, but doesn't affect the mean by a lot, so ...
The mean is centered among the other numbers in both sets of data.
_____
The mean without the outlier is 114. With the outlier, it is 107.4. The lower quartile is 108, so the mean does get moved outside the "box" of the box-and-whisker plot of the data set without the outlier.
Answer:
-sin(2A)
Step-by-step explanation:
1-(sin(A)+cons(A))^2
1-(sin(A)^2+2sin(A)cos(A)+cos(A)^2) :use FOIL to get it
1-(1+sin(2A))
1-1-sin(2A)
-sin(2A)
