<span>This is the functionalist theory of aging. It is similar to traditional structural-functionalism of sociological theory. In such, having a function that a person or object can accomplish increases the utility and worth of the object (or person, in this case). This increase in utility increases the satisfaction, as well.</span>
The collection and collation of original data via direct contact with potential or existing customers. It is also called field research.
Answer:
Total Surface Area of Solid = C.s.a of hemisphere+C.s.a of cone+C.s.a of Cylinder
slant height of cone=√h²+r²
=√6²+8²
=√100
=10cm
height of cone = 10 cm
radius of hemisphere =radius of cone=radius of cylinder=8cm
T.S.A of solid=2πrh+2πr²+πrl
=πr[2h+2r+l]
=3.14*8[2*10+2*8+10]
=25.12[36+10]
=25.12*46
=1155.52 cm²

the reliability of the measurement
Answer:
the reliability of the measurement
Explanation:
Good Observations are more reliable and valid. Professor Ibrahim's refinement to define rating scales and be sure observers(seeing how they disagree on their observations and how this could affect research) are following this ensures judgement based on data collected from these individuals(observers) are more reliable, which will ensure construct validity.
