Answer: The scatterplot shows a positive correlation because the values of y increase as the values of x increase.
Which of the following is the best approximation of the correlation coefficient for the data displayed in the scatterplot? 0.5

Answer:
![y(t)=52sin(3.3t+\pi/2)+56](https://tex.z-dn.net/?f=y%28t%29%3D52sin%283.3t%2B%5Cpi%2F2%29%2B56)
Step-by-step explanation:
We are given that
Height of crest, h=108 feet
Time for one cycle, T=1.9 s
We have to find a sinusoidal function of the form y = A sin(ωt - Φ) + B that models the motion of the coaster train during this run starting at the top of a hill.
We are given
![y=Asin(\omega t-\phi)+B](https://tex.z-dn.net/?f=y%3DAsin%28%5Comega%20t-%5Cphi%29%2BB)
Amplitude,![A=\frac{108-4}{2}=52 feet](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B108-4%7D%7B2%7D%3D52%20feet)
![B=A+4=52+4=56 feet](https://tex.z-dn.net/?f=B%3DA%2B4%3D52%2B4%3D56%20feet)
![\omega=\frac{2\pi}{T}](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7B2%5Cpi%7D%7BT%7D)
Using the formula
![\omega=\frac{2\pi}{1.9}=3.3/s](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7B2%5Cpi%7D%7B1.9%7D%3D3.3%2Fs)
We assume,
Horizontal shift ![\phi=-\frac{\pi}{2}](https://tex.z-dn.net/?f=%5Cphi%3D-%5Cfrac%7B%5Cpi%7D%7B2%7D)
Substitute the values
![y(t)=52sin(3.3t+\pi/2)+56](https://tex.z-dn.net/?f=y%28t%29%3D52sin%283.3t%2B%5Cpi%2F2%29%2B56)
Hence, the sinusoidal function that models the motion of the coaster train during this run starting at the top of a hill is given by
![y(t)=52sin(3.3t+\pi/2)+56](https://tex.z-dn.net/?f=y%28t%29%3D52sin%283.3t%2B%5Cpi%2F2%29%2B56)
