Answer:
91.125
Step-by-step explanation:
Total number/ Total number of quantity
16+32+10+28+8+19+32+26+33+39+98+399
729
Divode by number of quantity (8)
729/8
=91.125

Paralell ines have same slope
perpendicular lines have slopes that multiply to -1
y=mx+b is slope intercept
m=slope
b is irrelivant for this problem
solve for y first
5x+7y=12
7y=-5x+12
y=-5/7x+12/7
paralell is same slopoe but differnt b
y=-5/7x+b
sub (5,2)
(x,y)
2=-5/7(5)+b
2=-25/7+b
29/7=b
y=-5/7x+29/7
perpendcular
-5/7 times what=-1
what=7/5
y=7/5x+b
(5,2)
2=7/5(5)+b
2=7+b
-5=b
y=7/5x-5
