Answer: quantitative
Step-by-step explanation:
Measured variables in statistics may be subdivided into quantitative or Qualitative variables depending on whether the variable in question is numeric or non-numeric. Variables which are designed to evaluate on the basis of Number or quantity may be termed as quantitative variables while those which measure attribute and are used for characterization are called Qualitative variables. In the scenario above, the variable is concerned with the determination of concentration of nitrogen draining into water bodies, concentration follows that numeric calculations be Made in other to determine the amount of nitrogen in milligram per Litre in a particular water body in other to prevent its effect on wildlife which could result from excessive concentration in water bodies.
Answer:
6
Step-by-step explanation:
The sum of the exterior angles of any polygon = 360°
Thus the sum of the interior angles = 2 × 360° = 720°
The sum of the interior angles of a polygon = 180° (n - 2), hence
180(n - 2) = 720 ← divide both sides by 180
n - 2 = 4 ← add 2 to both sides
n = 6
The polygon has 6 sides
Answer:
Its an Obtuse angles
Step-by-step explanation:
x+79=2x-37
(x+79)+(-79)=(2x-37)+(-79)
x+79-79=(2x-37)-79
x=2x-37-79
x=116
An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees.

For odd function f(-x)= -f(x)
1) f(-x)= sin(-x) = -sin(x)=-f(x) sin is odd function
2) f(-x) = sin(-2x) = -sin 2x=-f(x)
3) f(-x)= (-x)³+1 = -x³ +1 (not an odd function)To be an odd function, it should be like this:if a function is (x³+1), to be odd f(-x) should be -(x³+1)=-x³-14) f(x)= x/(x²+1)
f(-x) = (-x)/((-x)²+1)= -x/(x²+1)=-f(x)
So, f(-x) gives

,
that means that f(x)= x/(x²+1) is an odd function.
5)f(x) = ∛(2x)
f(-x) = ∛(2*(-x)=∛(2x*(-1)) = ∛(2x)*∛(-1)=
- ∛(2x)= -f(x)
