Please Help!!! I will mark the brainiest and 70 points!

darkest shaded- 0.8 times 0.7= 0.56

In the middle- 0.8 times 0.3= 0.24 times 0.2 times 0.7= 0.14  0.24 + 0.14= 0.38

Light- 0.2 times 0.3= 0.06

0.38 + 0.06=0.44

0.56 times 0.44= 0.2464

I hope this helped!

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.
