If 3 is added to twice a number, the result is 17. Find the number

Crank

Answer:

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call $x$ the number we want to find.

Twice the number is equal to

$2x$

So, if we add 3 to 2x, we get

$3+2x$

And we know that this is equal to 17:

$3+2x=17$

Now we can solve the equation to find x: first, we subtract 3 from both sides

$3+2x-3=17-3\\2x=14$

Now we divide both sides by 2:

$\frac{2x}{2}=\frac{14}{2}\\x=7$

Two cards are drawn in succession and without replacement from a standard deck of 52 cards. Find the probability that the second

Svetllana [295]

Answer:

The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497

Step-by-step explanation:

Total number of face cards = 12

Total cards = 52

Probability of getting face card on first draw= $\frac{12}{52}$

Remaining no. of face cards = 11

Remaining number of total cards = 51

Probability of getting face card on second draw= $\frac{11}{51}$

The probability that the second card is a face card if it’s known that the first card was a face card = $\frac{12}{52} \times \frac{11}{51}= \frac{12}{52} \times \frac{11}{51}=0.0497$

Hence The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
