The number of throws that the player make X follows binomial distribution.

The probability that the player makes x throws out of eleven throws is

$P(X=x)=C(x,11)0.5^x(0.5)^{11-x}=C(x,11)0.5^{11}$

The probability that the player makes at most nine out of eleven free throws

$\sum_{x=0}^9C(x,11)0.5^{11}=1-\sum_{x=10}^{11}C(x,11)0.5^{11}\\ =1-C(10,11)0.5^{11}-C(11,11)0.5^{11}=1-\frac{12}{2^{11}} \\ =1-\frac{3}{512} =\frac{509}{512}$

Correct choice is (B).

Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).

stich3 [128]

Answer:

$(g\cdot f) = -3x^2-3$

Step-by-step explanation:

$f(x) = x^2 + 1$

$g(x) = -3$

The problem state to multiply the function $f$ and $g$ so the symbol seems to be incorrect.

We actually want to calculate

$g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3$

Note

$g\circ f(x)=g(f(x))=g(x^2+1)=-3$
