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

Answer:

a1 = 4

a2= -2

a3 = -8

a4= -14

a5= -20

Step-by-step explanation:

a12= a1 + 11d

-62 = 4 + 11d

-62-4 = 11d

-66= 11d

d = \frac{-66}{11}\\

  = -6

a1 = 4

a2 = 4 - 6 = -2

a3 = 4 - (6×2) = -8

a4 = 4 - (6×3) = -14

a5 = 4 - (6×4) = -20

A boat is approaching a cliff known to be 40m tall. The angle of elevation is 30°. How far away is the boat from the cliff?
allochka39001 [22]

Answer:

x = 40 * \sqrt{3}  meters

Step-by-step explanation:

You have a 30-60-90 right triangle in this situation.

the height of this triangle is 40 meters

the opposite angle is 30 degrees.

use the tangent.

let x = distance between boat and cliff

tan 30 = 40/x

1/root (3) = 40/x

x = 40 * \sqrt{3}  meters
