The answer is -0.48.
First, you multiply 1.2 to 4 to get 4.8. Then, since the 4 wasn't 4 but 0.4, you have to divide 4.8 by 10 to get 0.48. Finally, since -1.2 is negative, you put a negative sign in front of 0.48 to get -0.48.
A: 25h
b:20h+30(h-30)
25h=20h+30(h-30)
5h=30h-30^2
-25h=-30^2
25h=30^2
h=900/25
8(3+5)...they have the same factor which is 8..check
1/6 because the first number that you roll doesn't matter so it depends on the 2nd roll, in which the probability of rolling a specific number is 1/6
