Means, Monics and More

Level pending

The arithmetic mean, the geometric mean and the harmonic mean of the roots of the polynomial P ( x ) = x 100 2 x 99 + 3 x 98 4 x 97 + ( ) 100 x + 101 \begin{aligned} P(x) = x^{100} - 2 x^{99} + 3 x^{98} - 4 x^{97} + (\cdots) - 100x + 101 \end{aligned} are the only roots of the monic polynomial Q ( x ) Q(x) .

Evaluate the sum of all true statements.

(0) = There are no true statements.

(1) = A M > G M > H M AM > GM > HM .

(2) = P ( x ) > Q ( x ) , x R P(x) > Q(x), \: x \in \mathbb{R} .

(4) = Q ( 0 ) > 2 Q(0) > 2 .

(8) = P ( x ) P(x) has no real roots.

(16) = Q ( Q ( x ) ) Q(Q(x)) has 6 real roots.


The answer is 10.
