Answer:

The registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.

Step-by-step explanation:

We are given the following in the question:

The U.S. Department of Transportation announces that of the 250 million registered passenger vehicles in the US, 2.1% are electro-gas hybrids.

Population and sample:

  • Population is collection of all the observations of individuals of interest.
  • Sample is a subset of population.
  • Population is always larger than the sample.
  • Population is the universal set of all observations.

Thus, for the given case,

Individual of interest:

250 million registered passenger vehicles in the US

Population of interest:

250 million registered passenger vehicles in the US

Sample:

2.1% electro-gas hybrids.

Thus, the registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.

The steps are +2 then *4 then -8 then ÷2

Input  is 5

5 +2 =7 *4 = 28-8 = 20 ÷2 = 10     Output is 10

Input  is 9

9 +2 =11 *4 = 44-8 = 36 ÷2 = 18     Output is 18

Input  is 14

14 +2 =16 *4 = 64-8 = 56 ÷2 = 28     Output is 28

Input  is 18

18 +2 =20 *4 = 80-8 = 72 ÷2 = 36     Output is 36

Input  is 23

23 +2 =25 *4 = 100-8 = 92 ÷2 = 46     Output is 46

Input  is 7.5

7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20     Output is 20

Input  is 11.54

11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08     Output is 23.08

10000*4%= 400 Geese year1

10400*4%=416 Geese  year 2

10816*4%= 432.64 Geese year 3

11,248.64*4%= 449.95 Geese. year 4

11248.64+449.95= 11698.59

What is the inverse of y = 3x + 9? A. y= 1/3x - 3 B. y = 1/3x + 9 C. y = -1/3x - 3 D. y = 9x + 3
Aneli [31]

Answer:

1/3x - 3

Step-by-step explanation:

To find the inverse, we exchange x and y and then solve for y

y =3x+9

Exchange x and y

x = 3y+9

Then solve for y

Subtract 9 from each side

x-9 =3y+9-9

x-9 = 3y

Divide by 3

1/3(x-9) = 3y/3

1/3(x-9) = y

Distribute

1/3x-3 = y

The inverse is 1/3 x -3
