Ahot air balloon descends to the ground. the function h(t) = 210 - 15t can be used to describe the altitude of the
balloon as it approaches the ground. which statement best describes the graph of the function that models the
descent of the balloon?
the graph is discrete because there cannot be fractional values for time.
the graph is discrete because there cannot be negative values for altitude.
the graph is continuous because there can be fractional values for time.
the graph is continuous because there can be negative values for altitude.

High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. because the number of slots remains relatively stable, some colleges reject more early applicants. suppose that for a recent admissions class, an ivy league college received 2851 applications for early admission. of this group, it admitted 1033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. in the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. counting the students admitted early and the students admitted during the regular admission process, the total class size was 2375. let e, r, and d represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool.suppose a student applies for early admission. what is the probability that the student will be admitted for early admission or be deferred and later admitted during the regular admission process?
