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.

i made a clay snake 9 5/8 inches long, but a section 1 7/8 inches long broke off. how longis the snake now?
Fofino [41]
The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8

= ((77 × 8) − (15 × 8)) / (8 × 8)

= (616 - 120) / 64

= 496/64

= 31/4

Tell whether x and y show direct variation.Explain your reasoning.If so, find k #3
WINSTONCH [101]

Answer:

x and y do not show direct variation.  

Step-by-step explanation:

The formula for direct variation is

y = kx     Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y <em>do not</em> show direct variation.

You need to multiply a negative to make it positive as a negative multiplied by a negative equals a positive. But anything besides -1,-2,-3,-4,-5 and all positves can be placed.
