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
