The base of the resulting right triangle is for both sides, and the height is as given. This triangle is isosceles, which means perpendiculars are medians and vice versa. Use the table to assess whether the number of trips home is independent of the student's college attendance status (in-state or out-of-state) or dependent on it. First, we drop a perpendicular, shown above, to the base of the triangle, cutting the triangle into two congruent right triangles. The height of a triangle with sides 10, 10, and 16, if we use 16 as the base is 6 (Pythagorean Theorem and diagram below). Suppose you let event A A A represent whether the students attend an in-state or an out-of-state college, and event B B B represent whether the students visit home more than four times or visit home four or fewer times. Enter each fraction as a percent rounded to the nearest tenth, if necessary.Ĭ. Organize the responses in a two-way frequency table.ī. Of the 740 students who attend an out-of-state college, 118 visited home more than four times and 622 visited home four or less times.Ī. The survey finds that of the 1260 students who attend an in-state college, 928 visited home more than four times and 332 visited home four or less times. (i) equilateral triangle with side 10 cm.
