Answer:
The correct answer is Non-representative.
Explanation:
When a non-representative study is conducted. The researchers face or seek random samples in order to make their studies. On the other hand, a representative study is conducted with the purpose of looking for more specific or accurate samples.
Answer:
<em>The second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>
Step-by-step explanation:
We can't confirm the length of these diagonals based on the appearance of the figure, so let us apply Pythagorean Theorem;
This diagonal divides each figure ( square + rectangle ) into two congruent, right angle triangles ⇒ from which we may apply Pythagorean Theorem, where the diagonal acts as the hypotenuse;
5^2 + 5^2 = x^2 ⇒ x is the length of the diagonal,
25 + 25 = x^2,
x^2 = 50,
x = √50
Now the same procedure can be applied to this other quadrilateral;
3^2 + 7^2 = x^2 ⇒ x is the length of the diagonal,
9 + 49 = x^2,
x^2 = 58,
x = √58
<em>Therefore the second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>
Answer:
y=2x^2−5x+18
Step-by-step explanation:
Answer:
a = 7 + 2b/5 + 3c/5
b=−35/2 + 5a/2 − 3c/2
c = −35/3 + 5a/3 − 2b/3
Step-by-step explanation:
Yes
Answer:
We let x be the number of hours both could the job together.
The fraction of the job done by Elias is
x/40
The fraction of the job done by Niko is
x/50
Together they would be able to finish the job
x/40 + x50 = 1
x = 1 / (1/40 + 1/50)
x = 22.22 min
