Given:
The quadratic equation is
To find:
The vertex of the given quadratic equation.
Solution:
If a quadratic function is , then
We have,
It can be written as
...(i)
Here, .
Putting in (i), we get
On further simplification, we get
So, the vertex of the given quadratic equation is .
Therefore, the correct option is A.
Answer:
The probability that the total loss, X + Y is less than 2 is P=0.235
Step-by-step explanation:
We know the joint density function:
To find the probability that (X+Y)<2, we can divide this in two steps.
- When X=0, Y should be less than 2. This is P(X=0,Y<2).
- When X=1, Y should be less than 1. This is P(X=1, Y<1).
We can calculate P(X=0,Y<2) as:
We can calculate P(X=1,Y<1) as:
Then
