<h2>Answer</h2>

Stratified sampling

<h2>Explanation</h2>

Stratified sampling is a process of dividing members of the population into homogeneous (separate) subgroups before sampling. Then a random sample is drawn from each group. Members in subgroups may not be fix and subgroups are created under specific type.

<h3>Example</h3>

Subgroup:  Sophomore, Junior, Senior classes

This sampling technique increases the precision of sampling by reducing sample size especially when population size is too large.

In cluster sampling, a random subset of population is created and then random sample drawn from it. Members of all subgroups are equal.

In systematic sampling, fixed intervals from the larger population create the subset of population. Members of all subgroups are equal.

Answer:  the first election returns reached his family estate in Hyde Park, New York, on a November night in 1936, Franklin Delano Roosevelt leaned back in his wheelchair, his signature cigarette holder at a cocky angle, blew a smoke ring and cried “Wow!” His huge margin in New Haven signaled that he was being swept into a second term in the White House with the largest popular vote in history at the time and the best showing in the electoral college since James Monroe ran unopposed in 1820.

The outpouring of millions of ballots for the Democratic ticket reflected the enormous admiration for what FDR had achieved in less than four years. He had been inaugurated in March 1933 during perilous times—one-third of the workforce jobless, industry all but paralyzed, farmers desperate, most of the banks shut down—and in his first 100 days he had put through a series of measures that lifted the nation’s spirits. In 1933 workers and businessmen marched in spectacular parades to demonstrate their support for the National Recovery Administration (NRA), Roosevelt’s agency for industrial mobilization, symbolized by its emblem, the blue eagle. Farmers were grateful for government subsidies dispensed by the newly created Agricultural Adjustment Administration

Morgarella [4.7K]

Answer:

d. the actual dimensions.

Explanation:

In Engineering, it is a standard and common practice to use drawings and models in the design and development of buildings, tools or systems that are being used for proffering solutions to specific problems in different fields such as banks, medicine, telecommunications and industries.

Hence, an architect or design engineer make use of drawings such as pictorial drawings, sketches, or architectural (technical) drawing to communicate ideas about a plan (design) to others, record and retain informations (ideas) so that they're not forgotten and analyze how different components of a plan (design) work together.

Architectural drawing is mainly implemented with computer-aided design (CAD) software and it's typically used in plans and blueprints that illustrates how to construct a building or an object.

Additionally, architectural drawings such as a section view in a general plan, show in detail how the areas of a building relate to each other, as well as accurately illustrating the actual (true) shape and size of a building in the design and development process.

In dimension drawings, the dimensions written on the drawing are the actual dimensions and the drawings are then made using a scale to reduce the drawing in same proportion.
