add them then divide by 3
16.00 + 40.00 + 130 = 186.00
186.00/3 = 62.00
the average is 62.00
To find the lower quartile take the number of terms=n=12
to find the lower quartile take the equation (n+1)/4= 3.25
this means that the lower quartile will be at the 3.25th position int he sequence when all the terms are ordered from smallest to largest. so when ordered: 12 19 19 19.5 20 28 28 28.5 34 36 45 45
so the lower quartile is between 19 and 19.5 exactly 19.125
Answer:
A
Step-by-step explanation:
![\dfrac{1}{3}+\dfrac{3}{5}+\dfrac{2}{3}= \left[ \dfrac{1}{3}+\dfrac{2}{3} \right]+\dfrac{3}{5}\\\\\\=\dfrac{3}{3}+\dfrac{3}{5}\\\\\\=1+\dfrac{3}{5}\\\\\\=\dfrac{5}{5}+\dfrac{3}{5}\\\\\\=\dfrac{8}{5}\\\\\\=1\dfrac{3}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B3%7D%7B5%7D%2B%5Cdfrac%7B2%7D%7B3%7D%3D%20%5Cleft%5B%20%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B2%7D%7B3%7D%20%5Cright%5D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B3%7D%7B3%7D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D1%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B5%7D%7B5%7D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B8%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D1%5Cdfrac%7B3%7D%7B5%7D)
