Answer:
9
Step-by-step explanation:
Let the equation of a parabola be
= 4ax.
Then , focal length of the parabola is a.
As , (0,0) is the vertex and its focus is (a,0)
Thus, focal length comes out to be a.
Here,
a is given as 9 units .
Thus focal length of the parabola, d, equals to 9 units

Step-by-step explanation:
mean- add all number/by the total nos
=231/10=23.1
median - the middle value of data after arranging in ascending order
11,14,15,16,23,23,27,27,32,43
therefore the median is 23
mode - is the no that has occurred more
so mode will be 23 and 27
