Identify whether the variable in the information below is qualitative or quantitative. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample.
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.

A ladder leans against the side of a house. The angle of elevation of the ladder is 73°, and the top of the ladder is 14 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.
Answer:
4.3 feets
Step-by-step explanation:
Given that:
Angle of elevation = 73°
Horizontal distance from foot of ladder to bottom of wall = x feets
Height of ladder = 14 feets
The horizontal distance, x :
Using trigonometry :
Tan θ = opposite / Adjacent
Tan θ = 14 / x
Tan 73 = 14 / x
3.2708526 * x = 14
x = 14 / 3.2708526
x = 4.2802295
x = 4.3 feets

3x+9=5x+21
What is x
Answer:
X = -6
1. 3x + 9 = 5x + 21
2. Subtract -5x from both sides
3x + 9 - 5x = 5x + 21 - 5x
3.-2x + 9 = 21
4. Subtract 9 from both sides
-2x + 9 - 9 = 21 - 9
5.-2x = 12
6. Divide both sides by -2
-2x/-2 = 12/-2
7. x= -6

Mr smith earns $75 a day plus $35 for each car he sells if e is the amount he earned and c is the number of cars he sold which expression below shows how much mr smith will earn in a day
Answer:
110
Step-by-step explanation:
So if add 75 + 35 you will get the number 110
Really hoped this helped
The expression Mr smith will earn in a day is e= 75 + 35c.
What is expression?
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an equation, a coefficient is a number that is multiplied by a variable.Given:
Mr smith earns $75 a day plus $35 for each.
if e is the amount he earned,
and c is the number of cars he sold
So, the amount he earned
e= 75 + 35c
Hence, the expression is e= 75 + 35c.

B
h
A
C
D 4
20
Answer:
is it A and C ):
Step-by-step explanation:
The value of h is 8 units.
What are similar triangles?"Two triangles are similar when their corresponding sides are in proportion and all corresponding angles are equal."
For given question,
ΔBAD and ΔCBD are similar triangle.
So, their sides are in proportion.
[tex]\Rightarrow \frac{BA}{CB}= \frac{AD}{BD}= \frac{BD}{CD}[/tex] ..................(i)
For given figure,
BD = h, CD = 4 units
Now, we find the length of the side AD.
⇒ AD = AC - CD
⇒ AD = 20 - 4
⇒ AD = 16 units
From (i),
[tex]\Rightarrow \frac{AD}{BD}= \frac{BD}{CD} \\\\\Rightarrow \frac{16}{h} =\frac{h}{4}\\\\ \Rightarrow 16\times 4=h\times h\\\\\Rightarrow h^2=64\\\\\Rightarrow h=8[/tex]
Therefore, the value of h is 8 units.
