Answer:

the second answer is right

Step-by-step explanation:

while it is true that W=25/8, the definition itself (25/8) makes it a rational number (= a ratio of 2 integer numbers). so, in total, the first answer is therefore wrong.

X=pi, and pi is a typical example of an irrational number. so, this second answer is correct.

sqrt(10) < 3.16666666666...

so, Y=sqrt(10) and not 3.166666666..., so the third answer is already wrong there.

and consequently, Z=3.166666... and not sqrt(10), so the fourth answer is therefore also wrong.

Let G denote the centroid of triangle ABC. If triangle ABG is equilateral with side length 2, then determine the perimeter of tr

zhannawk [14.2K]

We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA= $\sqrt{3}$ . Hence CM=GC+GM=3* $\sqrt{3} /$ . Now, since GM is normal to AB, we have by the pythagoeran theorem that:
$AC^2=AM^2+GM^2=BM^2+GM^2=BC^2$
Hence, we calculate from this that AC^2= 28, hence AC=2* $\sqrt{7}$ =BC. Thus, the perimeter of the triangle is 2+4* $\sqrt{7}$ .

Why might the range not be the best estimate of variability?

Zinaida [17]

It may be because the range isn't actually considered an average, it's shown using a box and whiskers diagram, Mode is the most common number. Mean is all the numbers added up and divided by the amount of values there are in the adding up process. so overall the range is less useful to show variability as it only shows the lowest and highest number in the data, and not the different individual numbers variety amongst the results
