The lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of 17 days. in what range would you expect to find the middle 95% of most pregnancies?

yes yes yes yes yes yes yes yes yes

true !

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
