Answer 2

Answer:

Task 5: 11

Step-by-step explanation:

Task 5:

Let the hidden card be x, the for finding we need to arrange them in ascending order, so we should first arrange the numbers that we have:

7, 8, 15.

Now,

case 1) if we assume x to be greater than 15, then : 7,8,15,x (Ascending order) then our median would be $\frac{(8+15)}{2}$=11.5. which is not the case here as median is given to be 9.5.

case 2) if we assume x to be lesser than 7, then : x,7,8,15 (Ascending order) then our median would be $\frac{(7+8)}{2}$=7.5. which is not the case here as median is given to be 9.5.

case 3) So, now we assume x to be somewhere between 7 and 15. then : 7,x,8,15 or 7,8,x,15; whichever be the case, in both of them median will be =$\frac{(8+x)}{2}$ which is already given to us to be 9.5.

Therefore, $\frac{(8+x)}{2}$=9.5

=> (8+x)=9.5x2=19

=>8+x=19 then =>x=19-8=11.
