31) Heating or Cooling by Convection If air at a constant temperature, Te, flows over a small solid object whose temperature is T, the object's temperature is determined by Newton's law of cooling: dT :-k(T – T.) dt where t is time and k is a experimentally determined constant with units of reciprocal time (so if t is in sec (seconds), k is in sec). If the temperature, T, equals some value To > T, at t = 0, determine T(t). Note: if your answer is correct, you will able to verify that T→ Te as t → o.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
