Find x in this right triangle.

maks197457 [2]

Answer:

<em>x = 12</em>

Solve for x:

<em>Using Pythagorean Theorem </em>

a^2 + b^2 = c^2

a = 9

c = 15

b = x

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 144 | sqrt

x = 12

You are dealt two cards successively without replacement from a standard deck of 52 playing cards. Find the probability that the

kondaur [170]

Answer:

$\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%$

Step-by-step explanation:

There are 52 cards in a standard deck, and there are 4 suits for each card. Therefore there are 4 twos and 4 tens.

At first we have 52 cards to choose from, and we need to get 1 of the 4 twos, therefore the probability is just

$\frac{4}{52}$

After we've chosen a two, we need to choose one of the 4 tens. But remember that we're now choosing out of a deck of just 51 cards, since one card was removed. Therefore the probability is

$\frac{4}{51}$

Now to get the total probability we need to multiply the two probabilities together

$\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%$
