Answer:
![n(A \cup B) = 6](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%206)
Step-by-step explanation:
In Venn sets, we have that:
![n(A \cup B) = n(A) + n(B) - n(A \cap B)](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%20n%28A%29%20%2B%20n%28B%29%20-%20n%28A%20%5Ccap%20B%29)
In which n is the number of elements that each set contains.
In this question:
![n(A) = 8, n(B) = 9, n(A \cap B) = 6](https://tex.z-dn.net/?f=n%28A%29%20%3D%208%2C%20n%28B%29%20%3D%209%2C%20n%28A%20%5Ccap%20B%29%20%3D%206)
So
![n(A \cup B) = n(A) + n(B) - n(A \cap B) = 8 + 9 - 6 = 17 - 6 = 11](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%20n%28A%29%20%2B%20n%28B%29%20-%20n%28A%20%5Ccap%20B%29%20%3D%208%20%2B%209%20-%206%20%3D%2017%20-%206%20%3D%2011)
So
![n(A \cup B) = 6](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%206)
Answer: ~15.05267 (im not sure though i just used a calculator)
Answer:
v = -8.8
Step-by-step explanation:
4.3v + 10.75 = 8.11 + 4v
0.3v + 10.75 = 8.11
0.3v = -2.64
v = -2.64 / 0.3
v = -8.8
5x10+15-40(50)+40+10+24
50+15-40(50)+40+10+24
65-40=25+50=75+40=110+10=120+24=144
144 is your answer
