Arestaurant sells an average of 25 bottles of wine per night, with a variance of 25. assuming the central limit theorem applies, what is the probability that the restaurant will sell more than 600 bottles in the next 30 days? (hint: if x is a random variable indicating one day sale, then assume x ∼ poisson(λ = 25); use related d, p, q, and r functions to get the numerical answer.)

Yes of course i will indeed you with your problem.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
