(2-7i)(-1+4i)
2x-1=-2
2x4i= 8i
-7ix-1=7i
-7ix4i=-28i^2

so the answer is
-2+8i+7i+28i^2
=28i^2+15i-2

What percent of students ran the mile in 12 minutes or less?

otez555 [7]

41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran. Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.
