algebra Use a table to find the product. (3k - 1)(4k + 9) Verified answer calculus Let $$ \alpha , \beta $$ , and $$ \gamma $$ be the angles of a triangle. (a) Use Lagrange multipliers to find the maximum value of $$ f ( \alpha , \beta , \gamma ) = \cos \alpha \cos \beta \cos \gamma $$ , and determine the angles for which the maximum occurs. (b) Express $$ f ( \alpha , \beta , \gamma ) $$ as a function of $$ \alpha $$ and $$ \beta $$ alone, and use a CAS to graph this function of two variables.

A method of probability sampling (where all members of the population have an equal chance of being included) Population is divided into 'strata' (sub populations) and random samples are drawn from each. This increases representativeness as a proportion of each population is represented.
When should the method of stratified random sampling be used quizlet?Stratified sampling is useful when the strata differ from one another, but the individuals within a stratum tend to be alike. In cluster sampling, items are drawn from the population in groups, or clusters.
What sampling is like stratified sampling?Stratified Sampling and Cluster Sampling are both a part of probability sampling in statistical analysis. Probability Sampling is a procedure of selecting samples from a broad population for any kind of market research study.
Which sampling method samples are selected at random?Probability sampling refers to the selection of a sample from a population, when this selection is based on the principle of randomization, that is, random selection or chance.
