the mean of five numbers is 30 if one nimber is excluded their mean becomes 28 find expacted number?​

38

Step-by-step explanation:

Mean = sum of numbers / total number

30 = sum of numbers / 5

sum of numbers = 30 x 5 = 150

28 = sum of numbers / 4

Sum of numbers = 28 x 4 = 112

Difference = 150 - 112 = 38

a=r

d=q

c=p

b=s

hope this !

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
