The midpoint is (0, 1/2)
hope this helps
Answer:
B
Step-by-step explanation:
The line runs through Greenwich
The partitions involves dividing the line into subsegments
The coordinate of the point on the directed line segment is (0.5,-2)
<h3>How to partition the line?</h3>
The given parameters are:-
line segment = (-1, -1) to (5,-5)
Segment ratio = 1 : 3
The coordinates of the partition is calculated as:
![(x,y) = (\frac{mx_2 + nx_1}{m+ n},\frac{my_2 + ny_1}{m+ n})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7Bmx_2%20%2B%20nx_1%7D%7Bm%2B%20n%7D%2C%5Cfrac%7Bmy_2%20%2B%20ny_1%7D%7Bm%2B%20n%7D%29)
Substitute known values
![(x,y) = (\frac{1 *5 + 3 * -1}{1+ 3},\frac{1 *-5 + 3 * -1}{1+ 3})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7B1%20%2A5%20%2B%203%20%2A%20-1%7D%7B1%2B%203%7D%2C%5Cfrac%7B1%20%2A-5%20%2B%203%20%2A%20-1%7D%7B1%2B%203%7D%29)
Evaluate the products
![(x,y) = (\frac{2}{4},\frac{-8}{4})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7B2%7D%7B4%7D%2C%5Cfrac%7B-8%7D%7B4%7D%29)
Evaluate the quotients
![(x,y) = (0.5,-2)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%280.5%2C-2%29)
Hence, the coordinate of the partition is (x,y) = (0.5,-2)

Answer:
64
Step-by-step explanation:
![mean=\frac{sum\ of\ total\ number\ of\ score}{total\ number\ of\ students}](https://tex.z-dn.net/?f=mean%3D%5Cfrac%7Bsum%5C%20of%5C%20total%5C%20number%5C%20of%5C%20score%7D%7Btotal%5C%20number%5C%20of%5C%20students%7D)
we have given that mean of 9 students is 84
so total score of 9 students = mean×9
=84×9=756
and we have given mean score of exam is 82 and there is total 10 students so the total score of 10 students =10×82
=820
so the unreadable score = score of 10 students -score of 9 students =820-756=64
