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

Find the missing length. The triangles are similar.
Marina CMI [18]

Answer:

RK= 13      SK= 12

Step-by-step explanation

First, we find the missing length of RK using the given information: 65-52=13

Then we divide 65 by 13 to get a scale factor: 65/13=5

(To check, we multipuly: 13*5=65)

We then apply the scale factor to MK to find SK: 60/5=12

(To check we multipuly: 5*12=60)

We now have our answers: RK:13, SK:12
