<span>Often the university sites exist primarily for internal use, listing equipment and demos available to physics professors teaching large sections of introductory courses. They usually give lists of required equipment, they don't always give much information about setup, effective presentation and explanation of the physics.</span>
What does the central limit theorem tell us about the
distribution of those mean ages?
<span>A. </span>Because n>30, the sampling
dist of the mean ages can be approximated by a normal dist with a mean u and a
SD o/sqrt 54,
Whenever n<span>>30 the central limit theory applies.</span>
Harmonic mean between two positive numbers x and y, The simplified formula is 
I.e. you need to double the product of x and y then divide it by the sum of x and y...~
A. x = 9 and x = 11 is the answer you are looking for
Hope I helped you ^^
Answer is B, sodium acetate, because it is the solute
