Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2
Hi!
The point where the three altitudes of a triangle intersect is called the orthocenter.
Altitudes are lines which pass through the the vertex of a triangle, and bisect the other side.
There are three other points like an orthocenter; an incenter, a circumcenter, and a centroid. They're where the angle bisectors, the perpendicular bisectors, and the medians of a circle intersect, respectively.
Hope this helped!
A.) P(defective | foo) = P(defective & foo)/P(foo)
4% = P(defective & foo)/30% . . . . . . . . . plug in the given data
0.04*0.30 = P(defective & foo) = 0.012 = 1.2%
The probability that a widget was produced at the foo factory and is defective is 1.2%.
b.) P(defective | foo) ≠ P(defective) (4% ≠ 5%), so the events P(defective) and P(foo) are NOT independent.
c.) P(foo | defective) = P(defective & foo)/P(defective)
P(foo | defective) = 1.2%/5% = 24%
The probability that a widget was produced at the foo factory given it is defective is 24%.
