Is 6 over 3 an irrational number

No, you've already proven it's not irrational by writing it as 6/3.  You get 2.  

Step-by-step explanation:

An irrational number is any number that cannot be written as a fraction.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

probability for j is 1/4

while

a is 1/6
