What are the coordinates of the point on the directed line segment from (1, -6) to (8, 8) that partitions the segment into a rat
io of 4 to 3?
1 answer:
9514 1404 393
Answer:
(5, 2)
Step-by-step explanation:
Line segment AB is partitioned by point P into segments of the ratio m : n when point P satisfies ...
P = (mB +nA)/(m+n)
Here we want ...
P = (4(8, 8) +3(1, -6))/(4 +3) = (32 +3, 32 -18)/7 = (35/7, 14/7)
P = (5, 2)
The point (5, 2) partitions the segment into a ratio of 4 : 3.

Answer: x is less than or equal to 35.
Step-by-step explanation:
Assuming a normal distribution we find the standardized z scores for a:-
z1 = (80 - 180) / 25 = = -100/25 = -4
z2 = (280-180) / 25 = 4
Required P( -4 < z < 4) from the tables is >99.9%
b
z1 = 130-180 / 25 = -2
z2 = 230-180 / 25 = 2
from tables probability is 2* 0.4773 = 95.46 %
