315 - 4/15 = (314 + 1) - 4/15

= 314 + (15/15 - 4/15) . . . . . the process of taking 1 from the integer to make a fraction is sometimes called "borrowing"

= 314 + (15 -4)/15

= 314 11/15

To determine how a city’s residents feel about building a new youth center, a group considers surveying 50 random children at a
Lemur [1.5K]
This would result in a biased sample because:

- the survey is surveying elementary kids about a new youth center

most of those kids are more likely than not to want a youth center, so most of them will naturally agree without a doubt for the need of a youth center

- Even the adults at the elementary school are more likely than not to agree with a new youth center because they are teachers and can even benefit from working at the youth center

- in final words the reason why this survey will be biased is because there is no variety in the participants being tested. It is basically just asking teachers she students their preference, excluding the rest of an entire community

please vote my answer brainliest. thanks!
