Answer:
x = 2
Step-by-step explanation:
<u>Given</u>
2x^2-5+1=3
<u>Combine like terms</u>
-5 + 1 = -4
2x^2 - 4 = 4
<u>Add 4 to both sides</u>
2x^2 = 8
<u>Divide both sides by 2</u>
8/2 = 4
<u>Simplify</u>
x^2 = 4
<u>Square both sides</u>
![\sqrt{x^2} = x](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%7D%20%3D%20x)
![\sqrt{4}=2](https://tex.z-dn.net/?f=%5Csqrt%7B4%7D%3D2)
<u>Simplify</u>
x = 2
<u>Answer</u>
x = 2
Answer:
The experimental probability is 80%.
Step-by-step explanation:
Since approximately when there is a group of people, almost always half have the eyes of one color.
If the pool has 18 married and 22 not married, this means there are 40 people total
this means there’s a 18/40 probability that people who are married will be chosen
18/40 = 2/5
There is a 22/40 probability people who are un married will be chosen
22/40 = 11/20
