Question

if the mean of x observations is 30 and their mode is 75 then finds medium​

Answer 1

Answer:

We know that (formula)

Mode=3median-2mean

75=3median-2(30)

75=3median-60

135/3=median

45=median

Answer 2

Answer:

$\huge\boxed{\red{45}}$

Step-by-step explanation:

Formula for mean , median and mode

3 Median = Mode + 2 Mean

Median = ?

Mode = 75 .

Mean = 30 .

Let the median be x .

3 x = 75 + 30 × 2

⇒ 3 x = 75 + 60

⇒ 3 x = 135

⇒ x = 135/3

⇒ x = 45

Hence the median is 45 .

NOTE :

This type of formula is called empirical formula as it is approximate .

It is not 100% correct and accurate .
