Answer:
well for the cats she can do 3 for each and dogs 2 for each
After removing the outliers, the new total of student heights is
68*50 -82 -86 = 3232
so the new mean is
3232/48 = 67.33
1st angle = 2 * 2nd angle
3rd angle = 2nd angle + 80
1st angle = 2x
2nd angle = x
3rd angle = 80 + x
2x + x + 80 + x = 180
4x = 100
x = 25
1st angle = 50
2nd angle = 25
3rd angle = 105
1.)
-x=3-4x+6
3x=3+6
3x=9
X=3
c
2.)
-6+x=-2
x=4
B
