Answer:
all her patients patients with no cavities
patients younger than 18
every patient with braces
Step-by-step explanation:
when a sample is selected in a manner that some elements, in this case patients, of population have higher or lower probability of sampling then that sample is biased.
From given case, all the following are biased samples
all her patients patients with no cavities
patients younger than 18
every patient with braces
because they are non-random sample of a population in which all other elements were not equally likely to be chosen!
Well, how many minutes are there in a year? It would be way too easy to say "too many".
First, we calculate minutes in a day, which is 60 x 24 (minutes in an hour x number of hour)
This equals 1440. There are 365 days in a year, so we multiply 365 by 1440, which equals 525,600
The conversion of oz to gallon occurs, and bigger units mean division since their capacity makes the necessity for them significantly smaller; we divide 525600 by 128, and we get 4106.25.
4106.25 gallons of water are wasted in a year
Answer:
He generates a random whole number from 1 to 3.
