are you asking how many values of x there are? if so, i'm pretty sure the answer is 3.
-6/7p+1/7 um Idk what you wanted me to do but I added -4/7p with -2/7p
The numbers DO differ by 10 if they are
- 1 and 11
- 2 and 12
- 3 and 13
- 4 and 14
- 5 and 15
Each outcome technically has two ways of occurring, but since we're taking two marbles at a time, that would be the same as saying, for instance, that drawing 1 and 11 is the same as drawing 11 and 1. We only count such an event once.
So the answer is (a) 5.
Angle M equals 45°
Angle N equals 15°
