In a symmetric distribution, better known as the Gaussian or normal distribution, two thirds of the observations or 66.67% of the observation belongs to the area between the -3∅ to +3∅ where ∅ is the standard deviation of the group. it is assumed here that the mean is 1 and the area under the curve is also 1.

Answer:
w=14
Step-by-step explanation:
29-15=14
I have no idea 60-€ is the answer pop a chocky $70.00 or like $0.10
So first of all, we know that 16 oz= 1 pound.
Let's do a quick calculation:
3.2 pounds*(16 oz/1 pound)= 51.2 oz.
Note that pound (in 3.2 pounds) and pound (in 1 pound) cancels out so you get the oz unit.
Hope that would help :))
