Answer:
x=8
y=8√3
Step-by-step explanation:
y = cos 60° ×16 = ½× 16 = 8
x = sin 60° ×16 = ½√3 × 16 = 8√3

you flip the ratio from the original line
you multiply length times width times height.
Probabilities are used to determine the chances of events
The probability that two are nearsighted and one is not, is 0.0645
<h3>How to determine the probability</h3>
The given parameters are:
n = 3 -- the number of Australians selected
r = 2 --- the number that are nearsighted
p = 16% --- the proportion that are nearsighted.
The probability that two are nearsighted and one is not, is calculated using the following binomial probability formula
![P(x = r) = ^nC_r * p^r * (1 -p)^{n-r}](https://tex.z-dn.net/?f=P%28x%20%3D%20r%29%20%3D%20%5EnC_r%20%2A%20p%5Er%20%2A%20%281%20-p%29%5E%7Bn-r%7D)
So, we have:
![P(x = 2) = ^3C_2 * (16\%)^2 * (1 -16\%)^{3-2}](https://tex.z-dn.net/?f=P%28x%20%3D%202%29%20%3D%20%5E3C_2%20%2A%20%2816%5C%25%29%5E2%20%2A%20%281%20-16%5C%25%29%5E%7B3-2%7D)
![P(x = 2) = 0.0645](https://tex.z-dn.net/?f=P%28x%20%3D%202%29%20%3D%200.0645)
Hence, the probability that two are nearsighted and one is not, is 0.0645
