For the results of the study to be generalizable, the researchers should conduct an experiment .

Option E

Explanation:

A researcher is somebody who studies something, that is, a structured and structured investigation. Scientists are frequently described as scientists.

In conducting an experiment, the researcher will obey all the empirical measures of the process, from the feasibility of the theory to the use of controls and statistical testing.

Although all researchers use rationale, operationalization, and the scientific system steps, this isn't always an aware process.

Training and experience suggest that many scientists use an instinctive method, the' streamlined' scientific method, to perform an experiment. Using the basic steps, accurate findings are generally achieved, but where tests are difficult and costly, the strict scientific guidelines should always be followed.

The execution of an experiment has several stages, in which the experiment's conditions and form are made clear.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
