A person in a casino decides to play 3 games of blackjack. let w denote a win and l denote a loss. define the event a as "the pe

Ann [662]

Answer: The answer is {(w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l), (l, w, w)}.

Step-by-step explanation: Given that a person in the casino is going to play 3 games of blackjack. Here, 'w' denotes a win and 'l' denotes a loss.

Also, let 'A' be the event that the person wins at least one game of blackjack. Then, the outcomes of Event 'A' are

(i) win in 1st game loss in 2nd game loss in 3rd game

(ii) win in 1st game win in 2nd game loss in 3rd game

(iii) win in 1st game loss in 2nd game win in 3rd game

(iv) win in 1st game win in 2nd game win in 3rd game

(v) loss in 1st game loss in 2nd game win in 3rd game

(vi) loss in 1st game win in 2nd game loss in 3rd game

(vii) loss in 1st game win in 2nd game win in 3rd game

Thus, the outcomes of the event A are (w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l) and (l, w, w).

Thus, A = {(w, l, l), (w, w, l), (w, l, w), (w, w, w), (l, l, w), (l, w, l), (l, w, w)}.

Which of the following statments are true of the graph of the function f(x) = (x + 5)(x - 3). Select all that apply. pleaseee he

xeze [42]

Answer:

B, D, and E.

Step-by-step explanation:

We are given the graph:

$f(x)=(x+5)(x-3)$

We can expand the equation into standard form:

$f(x)=x^2+2x-15$

Since the leading coefficient is positive, our parabola curves up. Hence, it has a relative minimum.

The x-intercepts of a function is whenever y = 0. Hence:

$0=(x+5)(x-3)$

Zero Product Property:

$x+5=0\text{ or } x-3=0$

Solve:

$x=-5\text{ or } x=3$

So, our x-intercepts are (-5, 0) and (3, 0).

The y-intercept occurs when x = 0. Hence:

$f(0)=(0+5)(0-3)=-15$

So the y-intercept is (0, -15).

The axis of symmetry is given by:

$\displaystyle x=-\frac{b}{2a}$

In this case, from standard form, a = 1, b = 2, and c = -15. Hence:

$\displaystyle x=-\frac{2}{2(1)}=-1$

Our axis of symmetry is -1.

Therefore, the correct statements are B, D, and E.
