Answer:
x=9
Step-by-step explanation:
Since this is an equilateral triangle, all angles are equal to (180/3) 60 degrees
<N = 60 = 7x-3
60 = 7x-3
Add 3 to each side
60+3 = 7x-3+3
63 =7x
Divide by 7
63/7 =7x/7
9 =x
I believe that the answer you need is x=0.42
The mathematical expectation of Option A is 4. The mathematical expectation of Option B is 2.75. Option A offers a greater likelihood of advancing to the finish line.
b is correct
