Answer:
Q.6 P(2)=2+2*2²-2³
P(2)=2
Step-by-step explanation:
6. p(x) = 2 + x + 2x^2 - x^3
In correct order: p(x) = -x^3 + 2x^2 + x +2
-x^3 + 2x^2 + x +2 = -2^3+2×2^2+2+2
-x^3 + 2x^2 + x +2 = -2^3+2×2^2+2+2 = -8+ 8 + 2+ 2
-x^3 + 2x^2 + x +2 = -2^3+2×2^2+2+2 = -8+ 8 + 2+ 2 = 2+2
-x^3 + 2x^2 + x +2 = -2^3+2×2^2+2+2 = -8+ 8 + 2+ 2 = 2+2 = 4
7. Number of balls played by the batsman = 30
Number of balls in which he hits boundaries = 6
Number of balls in which he hits boundaries = 6∴ Number of balls in which he did not hit a boundary = 30 − 6 = 24
Number of balls in which he hits boundaries = 6∴ Number of balls in which he did not hit a boundary = 30 − 6 = 24P = 24/30
= 45
45Thus, the probability that he did not hit a boundary is 45
9. The given value of x = 2
And given value of y = 1
In the given equation: 2x + 3y = K
= 2 × 2+ 3 × 1
= 4+3 = K
= K= 7
