When is choosing a sample from a population least likely to be appropriate? choose all that apply.
when the population is small
when the population is large
when the sample contains proportions of items/events/people that are different from those of the population
when the sample contains only items/events/people that reflect the population
when surveying the entire population is time consuming
when surveying the entire population is expensive

when the population is small

when the sample contains proportions of items/events/people that are different from those of the population

Step-by-step explanation:

The sampling method is resorted to only when

i) population is large

ii) Surveying entire population is time consuming

iii) surveying the entire population is expensive

iv) when the sample contains only items/events/people that reflect the population

Otherwise, when population is very small we can survey the whole population instead of sample.

Similarly when sample contains proportions of items/events/people that are different from those of the population, the survey will not be effective if sampling is adopted

Hence we have choosing a sample from a population least likely to be appropriate whenever

the population is small

and or  the sample contains proportions of items/events/people that are different from those of the population

A) and C)

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
