Vtriangle d e f is shown. angle e f d is a right angle. the length of e f is 24 and the length of d f is 7.
which trigonometric ratios are correct for triangle def? select three options.
sin(d) = startfraction 24 over 25 endfraction
cos(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 24 over 7 endfraction
sin(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 7 over 24 endfraction

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

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?
