Answer:
z=(-6)
Step-by-step explanation:
(2/3)*z=(-4)
2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.
2*z=(-12)
z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.
z=(-6)
Answer:
-s = -4
Step-by-step explanation:

That condition is true if P(A) and P(B) are independent of one another. For example, if I was pulling marbles out of a bag, if I am replacing the marbles back after I pull one out, then P(A or B) = P(a)+P(B).
Answer: 3 minutes
