We know that the diagonals of a rectangle bisect each other.
So, If we draw the second diagonal of the rectangle, it will bisect the first diagonal, which is the hypotenuse of the triangle.
Also, in a rectangle, the bisectors of the sides and the diagonals are concurrent.
Hence, if we draw bisectors of the two sides of the given triangle, these bisectors and the second diagonal, which is the bisector of the hypotenuse, meet at a point.
Circumcenter of a triangle is nothing but the point of intersection of the bisectors of the sides of the triangle.
Since the above bisectors and the hypotenuse (the first diagonal of the rectangle) are concurrent, the circumcentre lies on the hypotenuse.
Hence, the circumcenter lies on the hypotenuse of the triangle.
The z-score for 5 minutes is found from:
Reference to a normal distribution table shows that the cumulative probability for a z-score of 1.667 is around 0.9522.
Therefore the probability that a conversation lasts for longer than 5 minutes is:
1 - 0.9522 = 0.048 to 3 d.p.
Answer:
The answer is 60
Step-by-step explanation:
I am going to assume that A and a are the same variable. For future reference, a and A wouldn't be considered the same variable so be careful with that :)
We can first plug in 2 for a and 4 for b
4(2) + 2(4^2) - 2(2 - 3(4))
8 + 2(16) - 2(2 - 12)
8 + 32 - 2(-10)
8 + 32 - (-20)
8 + 32 + 20
60
