Answer:

Independent Events

The outcome of one event does not affect the other.

If A and B are independent events then the probability of both occurring is

P(A and B)=P(A)×P(B)

Dependent Events

The outcome of one even affects the outcome ot the other.

If A and B are dependent events then the probability of both occurring is

P(A and B)=P(A)×P(B| A)

(B| A) - probability of B given A

A statue is mounted on top of a 16 foot hill. From the base of the hill to where you are standing is 77 feet and the statue subt

DanielleElmas [232]

Consider right triangle with vertices B - base of the hill, S - top of the statue and Y - you. In this triangle angle B is right and angle Y is 13.2°. If h is a height of the statue, then the legs YB and BS have lengths 77 ft and 16+h ft.

You have lengths of two legs and measure of one acute angle, then you can use tangent to find h:

$\tan 13.2^{\circ}=\dfrac{\text{opposite leg}}{\text{adjacent leg}} =\dfrac{16+h}{77}, \\ \\ 0.2345=\dfrac{16+h}{77},\\ \\ 16+h=0.2345\cdot 77=18.0565,\\ h=18.0565-16=2.0565$ ft.
