Answer:
9.24
Step-by-step explanation:
4.9 + (-1.2)(0.7)- (-5.18)
4.9 - 0.84 + 5.18
4.06 + 5.18
Answer: 9.24
4.9+ -1.2(0.7)- - 5.18
+ + = +
+ - = - + = -
- - = +
Therefore:
4.9+ -1.2(0.7)- - 5.18 = 4.9 - 1.2*(0.7) + 5.18 =4.9 - 0.84 + 5.18 = 9.24
now this assuming that M partitions XY on a 4:1 ratio "from X to Y", Check the picture below.
the probability is 1/6, or 16.6%
-3+4 cis (pi/20
D would be the answer
i hope this works :)
