Eight homerooms in a middle school had the following distribution of students. 29, 32, 33, 28, 30, 30, 29, 33

What is the MAD of students?
A. 1.25
B. 1.625
C. 2.25
D. 2.8

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
