\text{Answer: 0.02, 0.2, 2, 20, 200, 2000}

Step-by-step explanation:

Since we have given that

0.02,0.2,?,20,?,?

There is a pattern :

In First term,  2 is divided by 100 i.e. 0.02

In Second term, 2 is divided by 10 i.e. 0.2

In Third term, 2 is multiplied by 1 i.e. 2

In Fourth term, 2 is multiplied by 10 i.e. 20

In Fifth term, 2 is multiplied by 100 i.e. 200

In Sixth term, 2 is multiplied by 1000 i.e. 2000

So,

Sequence becomes

0.02,0.2,2,20,200,2000

  7. The population of interest is the 20 counties.
  8. The parameter of interest is the list of all counties in the U.S.

The objective of this essay is to test utilities provided by city governments, for this a sample of 20 counties was taken then contacted each city of them counting how many of them provided utilities to their residents, finding out that 12 out of 192 cities (6.25%) provided electricity to their residents.

The study variable is:

X: Number of city governments that provide utilities (electricity) to their residents, in a sample of 192.

The population of the study is the city governments in the U.S.

And the parameter of interest is the population proportion of city governments in the U.S. that provide electricity to their residents.

I hope it helps!

Solve the following system of equations by substitution
WITCHER [35]

Answer:

(-1, 1)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right  

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = 2x + 3

y = x + 2

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                  2x + 3 = x + 2
  2. [Subtraction Property of Equality] Subtract <em>x</em> on both sides:                         x + 3 = 2
  3. [Subtraction Property of Equality] Subtract 3 on both sides:                        x = -1

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em> [Original Equation]:                                                                  y = -1 + 2
  2. Add:                                                                                                                    y = 1
