Question

If 1≤x≤3 and 3≤y≤5. The least possible average of 1 x and 1 y is:

Answer 1

We are given

$1\leq x\leq 3$

So, smallest x-value is 1

$3\leq y\leq 5$

So, smallest y-value is 3

now, we can find least possible average

so, least possible average value is

$=\frac{1+3}{2}$

$=\frac{4}{2}$

$=2$

So,

The least possible average value is 2.........Answer
