Ecology: Wetlands Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environmental Prote

Olegator [25]

Answer:

a) The variable of the study is: milligrams of nitrogen per liter of water.

This is the amount that needs to be measured and analyzed to reach conclusions in the study.

b) The variable is quantitative. The quantitative variables are those that represent quantities. This variables can be measured on a continuous or discrete scale. Then, all the variables that you can measure or count are quantitative variables(height of trees, number of passengers per car, wind speed, milligrams of nitrogen per liter, etc). On the other hand, qualitative variables are those that can’ t be measured, and they represent attributes, like apple colors (red, green), size of trousers (small, medium, large) and so on.

c) The population under study is the milligrams of nitrogen per liter of water that are in the entire lake. You can estimate the parameters of the population by taking samples (In the example, 28 samples are taken).

Found out g<br> 2(g - 15) = -26 <br> Please help

posledela

Answer: $g=2$

Step-by-step explanation:

To solve this exercise you need to remember the following properties:

1. The Distributive property states that:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2. The Addition property of Equality statest that:

If $a=b$ , then $a+c=b+c$

3. The Subtraction property of Equality statest that:

If $a=b$ , then $a-c=b-c$

4. The Division property of Equality statest that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

5. The Multiplication property of Equality statest that:

If $a=b$ , then $a*c=b*c$

Given the equation:

$2(g - 15) = -26$

You must solve for "g" in order to find its value:

- Apply the Distributive property:

$2g - 30= -26$

- Apply the Addition property of Equality adding 30 to both sides of the equation:

$2g - 30+30= -26+30\\\\2g=4$

- Apply the Division property of Equality dividing both sides by 2:

$\frac{2g}{2}=\frac{4}{2}\\\\g=2$

The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.

Anon25 [30]

If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

PQ → (0, 3), (2, 0).

Substitute:

$m=\dfrac{0-3}{2-0}=\dfrac{-3}{2}=-1.5$

QR → (2, 0), (4, -3).

Substitute:

$m=\dfrac{-3-0}{4-2}=\dfrac{-3}{2}=-1.5$

CORRECT :)

<h3>Answer: m = -1.5.</h3>
