Answer:
<em>35.11 ft</em>
<em></em>
Step-by-step explanation:
This given situation can be thought of as triangle where PQ is the length of pole.
PR is the length of rope.
and QR is the distance of bottom of pole to the point of fastening of rope to the ground.
And
Given that:
PQ = 44 ft
PR = 51 ft
To find:
Side QR = ?
Solution:
We can apply Sine Rule here to find the unknown side.
Sine Rule:
Where
a is the side opposite to
b is the side opposite to
c is the side opposite to
Now,
Let us use the Sine rule again:
So, the answer is <em>35.11 ft</em>.
The probability that the number selected is the square of a natural number will be .
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
P is the probability
F(E) is the favorable event
T(E)is the total event
The probability is found as;
Hence the probability that the number selected is the square of a natural number will be .
