<span>If 75% of the students had taken 8 courses, 25% had not. Of these remaining 25%, 60% of them (or 60% of 25% = 15%) had taken 6 or 7 courses. Thus 90% (75% + 15%) of the students had taken 6, 7 or 8 courses.
Thus only 10% had taken less than 6 courses. I hope this helps.

Answer:
f^-1=(-1/4)x+1
Step-by-step explanation:
to solve for the inverse, you can just switch the x and the y:
y=-4x+4
switch:
x=-4y+4
subtract 4 from both sides:
x-4=-4y
divide by -4:
(-1/4)x-(-4/-4)=y
simplify:
(-1/4)x+1=y
Multiply both sides by 6:
6M = uh
Then divide both sides by h:
u = (6M)/h
