Sol : Here a=4 n=6 d=? Length of tree after 6 years would be a6 = a+(6-1)d => a6 = a+5d and after 4 years would be a4 = a+3d given a6 = 1/5 (a4)+a4 => a+5d = [1/5(a+3d)]+a+3d =>5a+25d = 6(a+3d) => 7d = a => d=4/7 Just a slight change in this. Initial height is 4 ft. So after one yr, is is 4+d after...

It is B - 32%. You don't need to divide by 2. m+d is on both sides.rohan_vus wrote:Not sure , i am taking a hit .
If 68 % fall within one standard deviation means 32 % are outside this . Since its symmetric around mean , so 32/2 = 16 % would be outside m + d .
