Not sure but i think its both 1/8ths...not sure though...sorry
Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
Upon simplifying we will get,
Therefore, Hannah donated books.

y=cos(2x)
<span>dy/dx=-2sin(2x) </span>
<span>dy/dx at the point x=pi/4 is </span>
<span>dy/dx=-2sin(2*pi/4) </span>
<span>dy/dx=-2 sin(pi/2) </span>
<span>dy/dx=-2 </span>
<span>therefore the slope of the tangent is -2
</span>
using this slope find the equation of the line
<span>(y-y')=m(x-x') </span>
<span>(y-0)=-2(x-pi/4) </span>
<span>y=-2(x-pi/4)</span>
