In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549

Answer:
6.50x+3.99
Step-by-step explanation:
every order of sweat shirts is charged 3.99
each individual sweatshirt costs 6.50 therefore x being the number purchased times 6.50 is the cost of the sweatshirts that plus the 3.99 is your total cost
The correct question is
Use calculator to find √(<span>68.1) to the nearest hundredth
we know that
T</span><span>o the nearest 'hundredth' is the same as saying </span>
<span>'Round off to two decimal places
</span><span>To do this you first have to determine the answer with a calculator to at least 3 decimal place
</span>√68.1-------> 8.252
The rounding will happen at the 5. It will either stay 5 or round up to 6, depending on the next digit which is a 2.
<span>The 2 is below 5, so the answer rounds down to give 8.25
</span>
the answer is
8.25
To solve for the answer of the question above, let x be the number of words on the list. As stated above, 2/3 of this is the number of words Martina needs to memorize which is 12. This may be expressed as,
(2/3)(x) = 12
Solving for x in the equation gives an answer of 18. Therefore, there are 18 words on the list.
