![115, 370, 250, 93, 540, 225, 177, 425, 318, 182, 275, and\ 228.](https://tex.z-dn.net/?f=115%2C%20370%2C%20250%2C%2093%2C%20540%2C%20225%2C%20177%2C%20425%2C%20318%2C%20182%2C%20275%2C%20and%5C%20%20228.)
find:
Sample mean=?
![=\frac{\text{total dental expenses}}{number \ of \ employees}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7Btotal%20dental%20expenses%7D%7D%7Bnumber%20%5C%20of%20%5C%20employees%7D)
![=\frac{115+370+250+93+540+ 225+ 177+ 425+ 318+ 182+ 275+228}{12}\\\\=\frac{3,198}{12}\\\\=266.5\\\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B115%2B370%2B250%2B93%2B540%2B%20225%2B%20177%2B%20425%2B%20318%2B%20182%2B%20275%2B228%7D%7B12%7D%5C%5C%5C%5C%3D%5Cfrac%7B3%2C198%7D%7B12%7D%5C%5C%5C%5C%3D266.5%5C%5C%5C%5C)
Answer:
f(x)= -54x -4
g(x)= -3x -2
f+g)( x)= -54x -4 -3x -2 = -57x -6
Use the formula for area of a circle,
![a = \pi \times {r}^{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cpi%20%5Ctimes%20%7Br%7D%5E%7B2%7D%20)
and they give an approximation so use that for pi
