3. Let a; = 40sin (351i) for i = 1, ..., 10. Let Q, be the frequency of a, falling into the interval (0, 13], Q2 be the frequency of a, falling into the interval (13, 18], Q3 be the frequency of r; falling into the interval (18, 26), and Q, be the frequency of r, falling into the interval (26, 31]. Let Q = In(3 + (Q1* + 21Q2| + 3|Q3| +4|Q4[). Then T =5sin (100Q) satisfies:- (A) O
