Show that crude death rate can be expressed as weighted arithmetic mean of age-specific death rates.

Show that criide death rate can be expressed as weighted arithmetic mean of age spefiic death rates.

Show that any function can be expressed as the sum of an odd function and even function

Show that the mean deviation with respect to Arithmetic mean is zero

The decomposition of dimethyl ether leads to the formation of CH_(4) , H_(2) and CO and the reaction -rate is given by Rate k[CH_(3)OCH_(3)]^(3//2) . The rate of reaction is followed by increase in pressure in a closed vessel , so the rate can also be expressed in terms of the partial pressure of dimethyl ether , i.e., Rate =k[P_(CH_(3)OCH_(3))]^(3//2) . If the pressure is measured in bar and time in minutes , then what are the units of rate and rate constants ?

For the first order reaction Ararr2B , rate can be expressed any one of the following rate equations. (1)-(d[A])/(dt)=k_(1) [A] (2) (d[B])/(dt)=k_(2) [A] Find the relation between k_(1) and k_(2) .

Show the ''difference between the arithmetic mean and median can never be greater then the standard deviation''.

What do you mean by rate law?

Show that the unit of a rate constant depends on the unit of time and the overall of the reaction.

Prove that the difference between the arithmetic mean and the medain can not be greater than the standard deviation. ]

What is crude rate of natural increase?
