Answer:
![P(A\cup B)= 0.875](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%200.875)
Step-by-step explanation:
From the diagram, none of the students play both instruments.
This means the two events are mutually exclusive.
![P(A\cup B)=P(A)+P(B)](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3DP%28A%29%2BP%28B%29%20)
The number of people playing instruments is 20.
![P(A\cup B)= \frac{20}{40} + \frac{15}{40}](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%20%5Cfrac%7B20%7D%7B40%7D%20%20%2B%20%20%5Cfrac%7B15%7D%7B40%7D%20)
![P(A\cup B)= \frac{35}{40}](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%20%5Cfrac%7B35%7D%7B40%7D%20)
![P(A\cup B)= 0.875](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%200.875)
Answer:
The square root of 8 in radical form is represented as √8 which is also equal to 2√2 and as a fraction, it is equal to 2.828 approximately.
1. Find all of the factors for 40.
2. Find the factors of 60.

Answer:
(5,-3) if the system is
y=x-8
2x+3y=1
Step-by-step explanation:
I think the system is to read:
y=x-8
2x+3y=1.
Please correct me if I'm wrong.
I'm going to plug 1st equation into 2nd equation giving me:
2x+3(x-8)=1 ->I replaced y with (x-8).
Distribute:
2x+3x-24=1
Combine like terms:
5x-24=1
Add 24 on both sides:
5x=25
Divide both sides by 5:
x=5
If y=x-8 and x=5, then y=5-8=-3.
The solution is (5,-3).
