When a six sided die is rolled then what is the probability that the number
rolled will be four?

1/6

Step-by-step explanation:

There are six numbers in total on the die.

Numbers ( 1 - 6 )

The number 4 appears only once on the die.

There is a 1/6 chance that the die would land on a four.

Hope this helps.  

if x = 1, then the answer is 3.5

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
