A light can shine blue (B), red (), or yellow (Y) Every second the color changes and is recorded. Estimate the probability the n
1 answer:
Answer:
The probability that the next color will be red is:
Step-by-step explanation:
The probability of an event is defined as:
Probability=(Total number of favourable outcomes)/(Total number of outcomes )
Here we have to find the probability that the next colour is red is given by:
<em>The recordings are given as:</em>
B R Y R R R R Y R B R R
Number of outcomes that red will come up=8
Total number of outcomes=12
Hence the probability is given by:

Please find the attached diagram for a better understanding of the question.
As we can see from the diagram,
RQ = 21 feet = height of the hill
PQ = 57 feet = Distance between you and the base of the hill
SR= h=height of the statue
=Angle subtended by the statue to where you are standing.
= which is unknown.
Let us begin solving now. The first step is to find the angle which can be found by using the following trigonometric ratio in
:
Which gives to be:
Now, we know that and
can be added to give us the complete angle
in the right triangle
.
We can again use the tan trigonometric ratio in to solve for the height of the statue, h.
This can be done as:
Thus, the height of the statue is approximately, 8.45 feet.
