We are given points 
and 
.
We first find the midpoint M, of AB, which divides the segment AB into 2 equal parts,
then we find the midpoint N of AM, and midpoint K of MB.
Thus each of the half parts is divided into 2 equal parts. The whole segment is divided into 4 equal parts.
The coordinates of M, N and K are found as follows:
the coordinates of M are:
the coordinates of N are:
similarly, the coordinates of k are:

Solution:
As 360°= 2 π Radian
1 Radian =
1. Sin(-1)= Sin ( )
= Sin (-57°16'22")=-0.84147
2.
= (229°54'32")
=75.963757 Degrees

= (5°43'38")
= 84.26083 Degrees
Answer:
0.0406, 0.8284,0.7887
Step-by-step explanation:
Given that Mattel Corporation produces a remote-controlled car that requires three AA batteries
X is N(34, 5.5)
Hence sample size of 25 would follow a t distribution with df = 24
This is because sample size <30
t distribution with df 24 would be bell shaped symmetrical about the mean and unimodal.
Std error of sample mean = std dev /sqrt n=
Prob (X>36) =
i.e nearly 4.1% of the sample would have a mean useful life of more than 36 hours
X>33.5 implies
=0.82837
=0.8284 proportion will have a mean useful life greater than 33.5 hours
Proportion between 33.5 and 36 hours
=
