Answer 2

Answer:

$29.84 \: is \: the \: answer.... \\ \\ median \: of \: 0 - 10 \: is(xi) \: 5 \\ median \: of \: 10 - 20 \: is(xi) \: 15 \\ median \: of \: 20 - 30 \: is(xi) \: 25 \\ median \: of \: 30 - 40 \: is(xi) \: 35 \\ median \: of \: 40 - 50 \: is(xi) \: 45 \\ then \: \: fi \: \: \: \: are \: \: 5 +8 + 15 + 20 + 14 = 62\\ then \: \: fixi \: are \: 25 + 120 + 375 + 700 + 630 = 1850 \\ then \: mode \: \: is \: \frac{fixi}{n} = 1850 \div 62 = 29.84 \\ plz \: mark \: it \: as \: brainliest \: answer \: plzzzzz$
