Suppose the weights of 1 year-old boys are approximately normally distributed, with a mean of 22.8 Ibs and a standard deviation of about 2.15. if we randomly select a 1-year-old boy, what is the probability that he'll weigh more than 20 pounds?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

Yes because all of the sides are the same length which makes it a flipped shape
