You select two cards from a standard deck of 52 cards, one after the other. What is the probability that you select and ace then a king? A. 1/13
B. 4/663
C 2/13
D 1/169

Answers

it would be 1/169 because it is not very likley

It would be 2/13 because imagine being given 4 decks of 13 cards and you have. Higher chance of having one to two of an ace or king in the deck compared to pulling none to all four. So 2/13 due to the ratio of 13

Answers

The inverse function theorem says

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(f^(-1)(16))}$

We have

$f(x)=x^2+4x-5$

defined on $x>-2$ , for which we get

$f^(-1)(x)=-2+√(x+9)$

and

$f^(-1)(16)=-2+√(16+9)=3$

The derivative of $f(x)$ is

$f'(x)=2x+4$

So we end up with

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(3)}=\frac1{10}$

Translate the sentence into an equation using n as the unknown number. Then solve the equation for n. Round to the nearest hundredth if necessary. The quotient of a number divided by 6 is 3.5.

Answers

Answer:

$(n)/(6)=3.5$

n= 21

Step-by-step explanation:

The equation is simple, you just have to reason the sentence, the quotient of a number, this means that the result of the division is 3.5, and the number has to be divided by 6, so the equation would end up looiking like this:

$(n)/(6)=3.5$

As 6 is dividing and you want to clear N, you just put it on the other side of the equation multiplying, and you end up with this:

n=6(3.5)

n=21

So your answer for this equation would be n= 6.

n/6 = 3.5
Multiply both sides by 6.
n = 21
