As a general rule, the normal distribution is used to approximate the sampling distribution of the sample proportion only if:a. the population proportion Π is close to 0.50.b. the underlying population is normal. c. the sample size n is greater than or equal to 30.d. nΠ and n(1-Π) are both greater than or equal to 5.

hope this : )

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 )
