Whta is the first quartile

the first quarter of the data

Step-by-step explanation:

lets say you have this data

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16

first, count the data, there is clearly 16 here.

split the data into four.

like this;

1, 2, 3, 4,  /  5, 6, 7, 8,/  9 ,10, 11,  12, / 13 , 14 ,15 ,16

the numbers before the first slash is the 1st quartile, the 2nd is before the second, the 3rd is before the third and the 4th is before the fourth slash.

to clear it up. 1, 2, 3, 4 would be your 1st quartile. the first 1/4 of the data.

Hope this helps. Good luck

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.
