Answer:
433
Step-by-step explanation:
Answer: The last paper has to be 99 over 100 to move the class average by 1 point
Step-by-step explanation:
total points on the 23 exams: 23*75 = 1725
-----
For 24 papers to average 76 points you need 24*76= 1824
---
Score on the final paper would have to be (1824-1725) = 99
Factoring (4x-14) would be 2(2x-7)
The answer is (24, 24).
Solution:
To find the point M that divides segment AB into 2:3 or 2/3 ratio, we determine k by writing the numerator of the ratio over the sum of the terms in the given ratio. Then, we calculate for the coordinates of point M from the slope of the line segment and the coordinates of A = (x1, y1) = (0, 0) and B = (x2, y2) = (60, 60) using the equation
(x, y) = (x1 + k(x2 - x1), y1 + k(y2 - y1) )
Therefore,
M = (x, y) = (0 + (2/5)(60 - 0), 0 + (2/5)(60 - 0)) = (24, 24)
