Answer:
A) cluster sampling ( b ) and systematic sampling ( e )
B ) Randomly selecting precincts increases the likelihood that the people polled represent the population well. ( c )
Step-by-step explanation:
Cluster sampling is a type of sampling plan used when there is an internally heterogeneous groups can be found inside a population that is supposed to be mutually homogeneous . while systematic sampling is a type of probability sampling that involves the selection of samples from a larger population at random but using a specific interval. to get the systematic sample the larger population is divided by the sample size.
from the information available in the report it is very evident that not all voters can be captured at once hence cluster sampling and systematic sampling would be employed .
B) the company will randomly select precinct to increase the likelihood of the sample size representing the entire population very well
Answer:
It gets quadrupled.
Step-by-step explanation:
Volume of cylinder is directly proportional to Height(h) and square of radius of base (r) with π as Constant of proportionality. ... If the height of a cylinder is doubled then the volume will get doubled. But, if the radius of the cylinder is doubled then the volume will get quadrupled.
The apples are x and cost $1, and the grapefruits are y and cost $2.
So, 1x and 2y
These together must equal $16
1x + 2y = 16
Hope this helped :)
