What is the probability that the manufacturing unit has carbon emission beyond the permissible emission level and the test predicts this?

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

false

5x+10 is the correct one

hope this

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
