Step-by-step explanation:
The mean of a group of values is calculated as
mean = 
Given 5 numbers with a mean of 12, then
= 12 ( multiply both sides by 5 )
sum = 60
let the number removed be x , then
= 11 ( multiply both sides by 4 )
60 - x = 44 ( subtract 60 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
The number removed was 16
Answer:
Step-by-step explanation:
since EG bisects angle DEF
31 = x + 15
31 - 15 = x
x = 16 degree
6x - 4 = 56
6x = 56 + 4
x = 60/6
x = 10
