Let's call the aces h, d, c, s for hearts, diamonds, clubs and spades. So, h, d are red and [ted] c, s[/tex] are black.

Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple

(x,y)\, x, y \in \{h,d,c,s\}

There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favour to deduce the probability of winning:

If we want a player to draw two card of the same colour, the following couples are good:

(h,h),\ (h,d),\ (d,h),\ (d,d),\ (c,c),\ (c,s),\ (s,c),\ (s,s)

so 8 possible couples over 16. This means that the probability that a player draws two cards of the same color is 8/16 = 1/2.

Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:

(h,c),\ (h,s),\ (d,c),\ (d,s)

which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.

Jay King, owner of a local Bed and Bath Store knows that his customers will only pay at most, $299 for a blow up bed. Assuming J
Roman55 [17]
If you would like to know the price Jay can pay the manufacturer for the blow up bed, you can calculate this using the following steps:

100% + 40% = 140%

140% of x is $299
140% * x = 299
140/100 * x = 299      /*100/140
x = 299 * 100 / 140
x = $213.6

40% of $213.6 = 40% * 213.6 = 40/100 * 213.6 = 85.44
$213.6 + $85.44 = $299

The correct result would be $213.6.

Factor the Polynomial: 20x³+34x²+6x = ?
Nataly_w [17]

Answer:

2x(5x+1)(2x+3)=0

Step-by-step explanation:

x{20x^2+34x+6}=0

2x(10x^2+17+3)=0

2x(10x^2+15x+2x+3)=0

2x{5x(2x+3)+1(2x+3)}=0

2x(5x+1)(2x+3)=0

The number 68 is increased to 73. What is the percentage by which the number was
Murljashka [212]

Answer: 1.1%

Step-by-step explanation:

To get a percentage you want to divide the ending number by the base number

73 / 68 = 1.07

It says to round to the neartest tenth, when rounding if the number is 5 or above you round up, if under 5 your number stays the same

7 is higher than 5 so we round up

1.1%
