Answer:

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AD}{CD}$ = $\frac{BD}{AD}$ , substitute values

$\frac{x}{13}$ = $\frac{3}{x}$ ( cross- multiply )

x² = 39 ( take the square root of both sides )

x = $\sqrt{39}$ → D

Tatiana [17]

Answer:

the probability that a student takes theater given that the student is taking choir is 0.3

Step-by-step explanation:

The probability that a student takes theater and choir = 0.078

The probability that a student takes choir = 0.26

the probability that a student takes theater given that the student is taking choir ?

We can solve this using conditional probability.

P(B|A) = P(A and B)/P(A)

In our case the conditional probability will be:

P(Theater | Choir) = P(Choir and Theater)/ P(Choir)

Putting the given values

P(Theater | Choir) = (0.078) / 0.26

P(Theater | Choir) = 0.3

So, the probability that a student takes theater given that the student is taking choir is 0.3
