Answer:

2 face cards

Step-by-step explanation:

By definition, there are 12 face cards (Kings, queens, and jacks) and 36 numbered cards (2's through 10's) in a standard deck of 52 cards.  Aces are not considered face cards (no face on the card).

The ratio of face cards in a full deck is (12/52) or slightly over 23%.

The likelihood of a face card in a hand of 8 cards is:

(8 cards)*(12 face cards/52 cards) = 1.85 cards.  We need to round to the nearest whole card, so the expected number of face cards in a hand of 8 is 2 cards.

Find the unknown side of the triangle and explain!!!
klasskru [66]

Since this is a right triangle, we can use Pythagorean theorem. Pythagorean theorem is a^2 + b^2 = c^2

a = one leg of the triangle

b = the second leg of the triangle

c = the hypotenuse of the triangle

in this problem,

a = 8 in

b = 6 in

c = ?

We need to plug our numbers into the pythagorean theorem and solve for c

8^2 + 6^2 = c^2.

Square each term on the left side.

64 + 36 = c^2

Add the terms together on the left side.

100 = c^2.

Take the square root of each side

10 = c

The missing side is 10 inches
