Question

mean+mode=42 and mean-mode=4 find meadian and mode

Answer 1

$hello$

→mean+mode=42
→mean=42-mode..( 1 )

→mean-mode=4
→(42-mode)-mode=4
→42-2mode=4
→-2mode=4-42
→
$mode = \frac{ - 38}{ - 2}$
→
$mode = 16 \: \\ answer$
→mean=42-mode
→mean=42-16
→
$mean = 26 \\ answer$


empirical formula⤵

→mode=3median-2meàn
→16=3median-2(26)
→16+52=3median
→68=3median
→
$median = \frac{63}{8}$
→
$median = 22.66 \\ answer$
