Ответ:
119
explained: you would have to take all the numbers and line them from greatest to smallest, for example 100,103,103,105,106,112,115,106,112,115,117,121,122,122,128,129,141,141,141
and since your median is your middle number, and you have an even set of numbers that means you will have two medians 117 and 121. You add them up and divide by two which equals 119.
Hope this helps!
