1. Find the median of the following data :
1) 3,1,5,6,3,4,5
2) 3,1,5,6,3,4,5,6

a ) The first step -  arrange them in ascending or descending.

1,3,3,4,5,5,6

then median is to find the middle so -

the middle of this is "4" (there are odd numbers of numbers)

b) the first step- -  arrange them in ascending or descending.

1,3,3,4,4,4,6,6

then median is to find the middle so -

here the middle is 4 and 4 ( there are even numbers of numbers)

so you find average -

4+4/2 = 4

these are the answers I guess.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

the answer will be b x² +x-1
