Question

If the mean of 4, x, 6, 9, y and 13 is 8 then x, y

Answer 1

Answer:

x=(0 to 8) if x is greater than 0 not specified

y=(0 to 8) if y is greater than 0 not specified

Step-by-step explanation:

Mean= 4+6+9+13+x+y÷5=8

=19+13+x+y÷5=8

=32+x+y=8×5

=32+x+y=40

=x+y=40-32

=x+y=8

Therefore,

x= or x>0 and y=0 or y>0

As x+y is even both x and y must be either even or odd.

x=(0 to 8)

y=(0 to 8)

There should be more conditions to solve this equation further.

Answer 2

Answer:

4+x+6+9+y+13÷6=8

32+x+y=48

x+y=48-32

x+y=16

therefore x=(0-16)

y=(16-0)
