The answer to this is very simple. First, just multiply 15.12 x 6.3 = 95.256
The discriminant of a quadratic equation is calculated through the equation,
D = b² - 4ac
In the given above, a = 5, b = -4, and c = 3. Substituting these values to the equation,
D = (-4)² - 4(5)(3) = -44
Since the discriminant is negative, the roots are non-real.

51/4 because you multiply 12*4 which is 48 and add 3 so you get 51. You keep the denominator so you should get 51/4.
Answer:
D
) Close to 50 times but probably not exactly 50 times
Reasoning:
Right in the beginning, we know that she flips the coin 100 times. Which means A and B cannot be true. Between C and D, only D makes sense because you can't be sure if something will land exactly a number of times.
