Suppose that you want to collect data on how frequently people in your community get sick. You decide to ask the first 100 people leaving a local doctor's office. a) Why might your results be biased?

i am not sure :

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
