9TrigonometryPythagorean TheoremInverse Trigonometry.
1 answer:
Given:
Given that a right triangle with one angle and one side.
Required:
To determine which of the option we need to use.
Explanation:
The given triangle is a right triangle and it having only one side and one angle.
Pythagorean Theorem : If in a triangle the square on one of the sides equals the sum of the squares on the remaining two sides of the triangle, then the angle contained by the remaining two sides of the triangle is right.
Therefore, here Pythagorean Theorem s not used.
We have to use the trigonometry formula.
Final Answer:
The option Trigonometry is correct.

Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:
In this problem, we have that the parameters are given as follows:
n = 4, p = 0.75.
Hence the mean and the standard deviation are given as follows:
- E(X) = np = 4 x 0.75 = 3.
