Answer:
Step-by-step explanation:
If 70 is 50% then 140 is 100%.
c is 75% of 140 = 105
a is 25% of 140 = 35
b is 100% of 140 =140
Step-by-step explanation:
-10-2x = 3x+15
5x = -25
x= -5

Answer:
21/2 = 10 1/2
21/2 = 21/2
True
Step-by-step explanation:
Here is what I got for the first one. MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|)
=1/5(2+0+4+7+13))
=5.2
And for the second one I got, MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|)
=1/5(1+2+8+7+4))
=4.4
