Answer:

\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}\\

Step-by-step explanation:

There are 14 marbles in total, of which 5 of them are red. Therefore, the probability that the first marble she chooses is red is \frac{5}{14}.

Since she does not replace the marble, there are now 13 marbles in total, of which 4 are red (she drew one of the red marbles on her first draw). Therefore the probability of her drawing a red marble on her second draw is \frac{4}{13}, assuming she draws a red marble on the first draw.

Thus, the probability she draws a red marble on both draws is \fbox{$\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}$}.

Given right triangle jkl, what is the value of cos(l)? five-thirteenths five-twelfths twelve-thirteenths twelve-fifths
kykrilka [37]

The value of the cosine ratio cos(L) is 5/13

<h3>How to determine the cosine ratio?</h3>

The complete question is added as an attachment


Start by calculating the hypotenuse (h) using

h^2 = 5^2 + 12^2

Evaluate the exponent

h^2 = 25 + 144

Evaluate the sum

h^2 = 169

Evaluate the exponent of both sides

h = 13

The cosine ratio is then calculated as:

cos(L) = KL/h

This gives

cos(L) =5/13

Hence, the value of the cosine ratio cos(L) is 5/13
