Take -9 to other side and get 4n=0
final answer n=0
we will have to buy 12.
<h3>How to solve?</h3>
We know to begin with that for x candy bards:
x / 10 = 0.89; x = 8.90
We are trying to ascertain how many bars (y) must be added to this to amount to have an average of 0.80. This is represented:
(8.9 + 0.72y) / (10 + y) = 0.8
8.9 + 0.72y = 0.8 (10 + y)
8.9 + 0.72y = 8 + 0.8y
8.9 – 8 = 0.8y - 0.72y
0.9 = 0.08y
y = 0.9 / 0.08 = 11.25
However, since we cannot have a partial amount of candy bars, we will have to buy 12.

In case of the given experiment, it is being asked either the applicants were admitted to the Park university or not, it has only two outcomes, Yes and no. So having only two options as outcomes this experiment is a binomial experiment ..
Well....you cant divide 50 and 60...it gives you 3,000 and every triangle equals 180 so.....if you do 50 x 50 to do both lines you'll get 2,500 so no luck there.....so...it doesnt equal..180
