Given the following formula, with A = 27 and t = 3, solve for r. <br> A=p(1+rt)

Nookie1986 [14]

Answer:

Step-by-step explanation:

The given formula is

$A=p(1+rt)$

Where $A=27$ and $t=3$

To solve for $r$ , first we need to move $p$

$\frac{A}{p}=1+rt$

Then, we move the term 1

$\frac{A}{p}-1=rt$

Finally, we move the factor $t$

$\frac{\frac{A}{p}-1 }{t} =r$

Replacing given values, we have

$\frac{\frac{27}{p}-1 }{3} =r\\r=\frac{\frac{27-p}{p} }{3} \\r=\frac{27-p}{3p}$

Thereofre, the right answer is A.

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a king and

STALIN [3.7K]

Answer:

0.0181 probability of choosing a king and then, without replacement, a face card.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of choosing a king:

There are four kings on a standard deck of 52 cards, so:

$P(A) = \frac{4}{52} = \frac{1}{13}$

Probability of choosing a face card, considering the previous card was a king.

12 face cards out of 51. So

$P(B|A) = \frac{12}{51}$

What is the probability of choosing a king and then, without replacement, a face card?

$P(A \cap B) = P(A)P(B|A) = \frac{1}{13} \times \frac{12}{51} = \frac{1*12}{13*51} = 0.0181$

0.0181 probability of choosing a king and then, without replacement, a face card.
