ΔABC is a right triangle in which angle B is a right angle, AB = 1, AC = 2, and BC = square root of 3 . cos C × sin A equals wha

ad-work [718]

Remark

Study the triangle carefully. It may not be exactly as you have drawn it, but it will work if you just follow the givens.

Givens

AC = 2

AB = 1

BC = sqrt(3)

Step One

Find Cos C

Cos(C) = adjacent / Hypotenuse

Cos(C) = BC / AB

Cos(C) = sqrt(3)/2

Step Two

Find Sin(A)

Sin(A) = opposite / hypotenuse

Sin(A) = AB / AC

Sin(A) = 1/2

Step Three

Find Cos(C) * Sin(A)

Cos(C) * Sin(A) = sqrt(3)/2 * 1/2 = sqrt(3) / 4 <<<< Answer

Q3. Consider two identical pack of cards A and B. When one card from A is taken and shuffled with the card B, the first top card

vivado [14]

Answer:

0.02

Step-by-step explanation:

Pack A and B both consisted of 52 cards. When shuffled, 51 cards in A and 53 cards in deck B. It appears that the Top card of A left with only 51 possible cards to be taken from A (since we know the Queen hadn't moved).

The two possible cases are: probability of not taking King of Hearts (from A to B), and the other were we did.

Let K= the event of taking the King of Hearts from A to B and be $B_{K}$ the occasion being the top card of B.

$P(B_{K} )=P(K)P(B_{K} |K)+P(K^{C} )P(B_{K} |K^{C} )\\$

$=\frac{1}{51} \frac{2}{53} +\frac{50}{51} \frac{1}{53}$

$=\frac{52}{2703} \\=0.02$
