Question

Mean of 17, 4, 8, 6, 15 is m'and median of 8, 14, 10, 5, 7, 20, 19, n is
(m-1). Find the values of m’and n'​

Answer 1

Answer:

m = 10, n = 8

Step-by-step explanation:

mean = sum of terms / total no of terms

= 4+6+8+15+17 / 5

= 50/5

= 10

m = 10 ---♳

median is the middle term when arranged in ascending order. if even no of terms are there then the average of middle 2 terms gives the median.

AO = 5,7,8,10,n,14,19,20

median = 10+n / 2

given median = (m-1)

so , m-1 = 10+n / 2

from ♳..m=10

then

9 = 10+n / 2

18 = 10+n

n = 8

hence solved..

here i took m' and m to be equal.if its not equal please do not follow this ans.
