Find the domain of the vector functions, r(t)r(t), listed below. You may use "-INF" for −[infinity]−[infinity] and use "INF" for [infinity][infinity] as necessary, and use "U" for a union symbol if a union of intervals is needed. a) r(t)=⟨ln(13t),t+8−−−−√,116−t√⟩

Renita analyzed two dot plots showing the snowfall during the winter months for city a and for city b. she found that the median snowfall is 5 inches less in city a than in city b. the mean snowfall is about 2 inches less in city a than in city b. which explains why there is a difference in the measures of center for the sets of data?
