The amount of pyridoxine (in grams) in a multiple vitamin is normally distributed with mean = 110 grams and standard deviation = 25 grams. what is the probability that a randomly selected vitamin will contain between 82 and 100 grams of pyridoxine?

0.21108

Explanation:

Given,

Mean,

Standard deviation,

Let X represents the amount of pyridoxine contained by vitamin,

So, the probability of vitamin will contain between 82 and 100 grams of pyridoxine,

= P( 82 ≤ X ≤ 100 )

= 0.21108

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
