Answer 2

Answer:

Step-by-step explanation:

(10×140) + (20×133) + (30×118) (40×100) + (50×75) + (60×45) + (70×25) + (80×9) + (90×2) all divided by ( 140 + 133+ 118+100+75+45+25+9+2) = 2700÷ 647 =4.173106646

we do this because the mean equals sum of all the numbers divided by the number of numbers.

i couldnt do the median cause there are too much numbers to find it
