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.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
