In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into 4 suits: spades,
liubo4ka [24]

Answer:

It is more likely she draws 2 red cards

Step-by-step explanation:

Given that:

Number of red d cards in deck = 26

Number of face cards = 4 * 3 = 12 face cards

If two cards are drawn with replacement ;

Probability = (required outcome / Total possible outcomes)

P(1st card red) = 26 /52) = 1/2

P(2nd card red) = 26 /52 = 1/2

P(1st card red) * P(2nd card red)

1/2 * 1/2 = 1/4 = 0.25

P(1st card face card) = 12/52 = 3/13

P(2nd card, face card) = 12/52 = 3/13

P(1st card face card) * P(2nd card face card)

3/13 * 3 /13 = 9/169 = 0.053

0.25 > 0.053

It is more likely she draws 2 red cards

x>0 \\ \\&#10;2 \log x= \log 64 \\&#10;\log x^2=\log 64 \\&#10;x^2=64 \\&#10;x=-8 \ \lor \ x=8 \ and \ x>0 \\&#10;\boxed{x=8}

Used formulas:
n \log_a b=\log_a b^n \\&#10;\log_a b, b>0

Peggy has saves 9,215. If she is paid $45 an hour, how many hours did she work?
Rus_ich [418]

First we set up our equation.  We know she has $9,215, and she gets paid $45 an hour.  So our variable would be the hours she has to work.

45n=9,215

Since we don't have any like terms to combine, we just divide both sides by 45, to isolate the variable.

n=204.8  Hope this helped!
