I think it would be easy to find it because its 30 feet away and even if he didn't know his feet he could always leave rocks/pebbles to the treasure so he won't lose it.
Answer:
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) =
OP.Cosθ = 1×Cosθ =
Cosθ =
θ = , where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = , where n = integer
Common value of θ will be, θ =
Option B will be the answer.
Answer: 0.0107
Step-by-step explanation:
Given : The time for the event for boys in secondary school is known to possess a normal distribution with
Let x be the random variable that represents the time for mile run in its secondary-school fitness test.
z-score :
Now, the probability that a randomly selected boy in secondary school can run the mile in less than 322 seconds is given by :-
Hence, the probability that a randomly selected boy in secondary school can run the mile in less than 322 seconds = 0.0107
