Question

if the mean of 2,4,6,8,x,y is 5 then find the value of x+y

Answer 1

Answer:

x + y = 10

Step-by-step explanation:

The mean is calculated as

mean = $\frac{total}{count}$, thus

$\frac{2+4+6+8+x+y}{6}$ = 5 ( multiply both sides by 6 )

20 + x + y = 30 ( subtract 20 from both sides )

x + y = 10
