The unknown length is the hypotenuse of the right angle formed when connecting the top of the second floor and the distance from the wall from which the belt is installed. Using the trigonometric function, sine, the equation becomes,
sin 60° = 12 ft / h
The value of h from the equation is 13.86 ft. Thus, the answer is 13.86 ft.
Using the Central Limit Theorem, the percentage that is expected to be the closest to the actual percentage is:
A. The Tribune, at 68%.
<h3>What does the Central Limit Theorem state?</h3>
It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean and standard error , as long as and .
From this, a larger sample size leads to a smaller error estimate. Since the Tribune had the largest sample size, option A is correct.

The answer is thirty two over twenty
Answer:
(-2.5,1)
Step-by-step explanation:
hope that helps
Answer:
B
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 ( subtract 1 from both sides )
sin²x + cos²x - 1 = 0 ( subtract sin²x from both sides )
cos²x - 1 = - sin²x
then
= ← cancel sin²Θ on numerator and denominator
=
= -
