Answer 2

Given,

l=40

h=15

f1=7

f2=6

fo=3

To Find,

Mode=?

Solution,

The formula for mode is  $l + (\frac{f_1 - f_0}{2*f_1 - f_0 -f_2} ) * h$

Putting values in the formula we get,

Mode = $l + (\frac{f_1 - f_0}{2*f_1 - f_0 -f_2} ) * h$

Mode = $40 + (\frac{7 - 3}{2*7 -3 -6} ) * 15$

Mode = $40 + (\frac{4}{14 -9} ) * 15$

Mode =$40 + (\frac{4}{5} ) * 15$

Mode = $40 + 4*3$

Mode = 40 + 12

Mode = 52

Hence, mode is 52
