Katie is thinking of starting a baby-sitting service and wants to figure out what percent of the population have young children. She goes to a community meeting about unsafe conditions on a playground and asks every fifth person attending the meeting if they have young children. Part A Explain why this sample is unlikely to be representative of the population.

The reason this sample is unlikely to be representative of the population is because she is only interviewing a community meeting, whereas the population of the world is 8 billion. It is not a good example of what the population is, because the meeting probably only has, tops, 100 people. The ratio here is 8 billion/100, which is why this sample is unlikely to be representative of the population.

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
