<h2>
0.87</h2>
Step-by-step explanation:
let A be the event that employees work full time
Pr(A) = 1 - 0.35= 0.65 ( given : Pr( employee work part time) = 0.35)
let B be the event that employees earn more than $20,540
Pr(B) = 0.52
Pr( employee work full time and earn more than $20,540) = 0.3
Pr( A∩B) = 0.3
we know that
Pr( employee work full time or earn more than $20,540) = Pr( A∪B)
Also
Pr( A∪B) = Pr(A) + Pr(B) - Pr(A∩B)
= 0.65 + 0.52 - 0.3
= 1.17 - 0.30
= 0.87

Answer:
3 buses are needed.
Step-by-step explanation:
If there are only 2 buses, it would be full, but there would still be 12 students without a bus. To take all students, you'd need 3 buses. 2 buses will be full, and the other bus would only have 12 students.
Answer: 4
Step-by-step explanation: I don't think you are in 1st grade but if you are here you go.
That would be
![x = + \frac{ \sqrt[]{3} }{ \sqrt[]{2} }](https://tex.z-dn.net/?f=x%20%3D%20%20%2B%20%5Cfrac%7B%20%5Csqrt%5B%5D%7B3%7D%20%7D%7B%20%5Csqrt%5B%5D%7B2%7D%20%7D%20)
BTW the plus sign is supposed to have this sign underneath it _
Good luck.
