The answer to this question should be: Participants should be selected into the treatment group randomly.

In an experiment, the participant is given an intervention and it hoped to change a parameter. In every experiment, you must ask the participant permission so they must be aware of the experiment. Since this is an experiment, the researcher is allowed to do something that changes the participant behavior as long as it is intentional for the research. The experiment questionnaire should be given to the participant, not the population.
By putting the participant randomly, you can minimize confounding factor from the participant.

jok3333 [9.3K]

The answer is length = 10 yd, width = 2 yd
proof
The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20

How many triangles can be constructed with angles measuring 120°, 40°, and 10°? one more than one none

FrozenT [24]

I might be wrong but i believe you can make more than one with those 3 angles. the 120 and 40 can make one and if angled right can make 2 and the 10 deg on one of the other angles lines would give you a 3rd.

$5\cdot\dfrac{x^2-2x}{6}:\dfrac{3x-6}{x}=5\cdot\dfrac{x(x-2)}{6}\cdot\dfrac{x}{3x-6}\\\\=5\cdot\dfrac{x(x-2)}{6}\cdot\dfrac{x}{3(x-2)}=\dfrac{5\cdot x\cdot x}{6\cdot3}=\dfrac{5x^2}{18}$
