Answer:
B. 1/3
Step-by-step explanation:
The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...
2 / 6 = x
If we simplify it would give us 
Add 1 to all parts.
-4+1<3x-1+1<5+1
-3x<3x<6
-3/3<3x/3<6/3

Answer:
-2.125
Step-by-step explanation:
Enrollment at X = 0 is at 20.
Enrollment at X = 8 is 120.
Find the difference between those values:
120 - 20 = 100
Divide that difference by the difference in the x values:
100 /8 = 12.5
The answer is D. 12.5
