In a recent survey, people were each asked the number of times they have been on an airplane. Here is a list of the responses. 8,10,21,8,9,13,24,12
Find the range of the data set.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: your answer is a
