Mark is flying a kite and realizes that 300 feet of string is out. Mark anchored the kite to the ground. The angle of the string
with the ground is 42.5∘. How high is Mark's kite above the ground? Find your answer to the nearest tenth.
1 answer:
Answer:
The kite is 202.7 feet above the ground
Step-by-step explanation:
The scenario is depictedd in the picture attached
we have to find the height.
Trigonometric ratios will be used to find the height.
So,
The height is 202.68 feet
Rounding off to the nearest tenth
202.7 feet
Therefore, the kite is 202.7 feet above the ground ..

Answer:
The expected number of times is 4.
Step-by-step explanation:
Looking at the question, we see that this follows a geometric distribution because it is asking for the expected number of trials hat will bring about the FIRST SUCCESS. The probability of success is
Since it is a geometric distribution, we know that the expected value of a random variable X, E(X) that follows a geometric distribution is given as:
E(X) = 1/p where p is the probability of success.
Therefore, the expected number of times will be
E(X) = 1/(1/p) = 1/(1/4) = 4.
Hence, the expected number of times is 4.
