You can't simplify it anymore
Step-by-step explanation:
Answer:
80 feet
Step-by-step explanation:
According to the tangent-secant theorem, the square of the tangent length is equal to the product of the secant segment and the external portion.
In other words:
30² = (10 + x) (10)
900 = 100 + 10x
800 = 10x
x = 80

The probability of a student taking a math class or a physics class is
when the probability of a student taking a math class is
, the probability of taking a physics class is
, and the probability of taking a math class and a physics class is ![0.15](https://tex.z-dn.net/?f=0.15)
How can we find the probability of taking math class or a physics class ?
Given in the question probability of the student taking class
![p(M)=0.70\\p(P)=0.30\\p( M and P)=0.15](https://tex.z-dn.net/?f=p%28M%29%3D0.70%5C%5Cp%28P%29%3D0.30%5C%5Cp%28%20M%20and%20P%29%3D0.15)
So we use the probability union intersection formula
![p(M or P)=p(M)+p(P)-p(M and P)](https://tex.z-dn.net/?f=p%28M%20or%20P%29%3Dp%28M%29%2Bp%28P%29-p%28M%20and%20P%29)
Substitute the values
![p(M or P)=0.7+0.3-0.15\\=0.85](https://tex.z-dn.net/?f=p%28M%20or%20P%29%3D0.7%2B0.3-0.15%5C%5C%3D0.85)
